Much work has also been done on P cycling in New Zealand steepland pasture and also some work on S (Search for; A Gillingham, J Rowarth, M Hedley) New Zealand work will generally refer to dairy production on rolling country, or mixed stock grazing on very steep country. (we do not have any feed lot production). I am looking at K tranfer patterns around steep land paddocks, and have found the use of detailed linear sampling patterns (eg one sample every 10m,in a line that covers changes from camp zones to infrequently grazed zones- samples are analysed individually) to yield the most infomation. I have been using a lot of multivariate analysis techniques to look at the patterns in the results. P, however, should be much more "stable" than K, and the deposition pattern across the paddock will be directly related the faeces deposition pattern (J Rowarth, PhD thesis, Massey University- can't remenber the date sorry- about 1988) Hope this helps :-) Sally ???!!!!oooooOOOOOPPPPPSSSsssssss.....

Date: Sat, 1 Mar 1997 14:25:30 -0600 From: Michael Russelle <russelle@SOILS.UMN.EDU> Subject: Re: Effect of Cattle ... on Soil P A few contacts: Cameron J.P. Gourley (gourleyc@dri.agvic.gov.au) is in charge of a large, multi-investigator study in Victoria, Australia, on the interaction of dairy cow stocking rate and P fertilization, in which P cycling is being measured. David Correll has ongoing research in the northeastern USA on how pastures influence nutrient losses and microorganism impacts on surface waters, and has a recently published summary of work in 'Nutrient Cycling in Forage Systems', R.E. Joost and C.A. Roberts (ed.), 1996. In the same volume, both Bruce Matthews (Hawaii) et al., and Paul Peterson and Jim Gerrish (Missouri) have chapters on nutrient distribution in pastures under various conditions. You likely have heard about Andrew Sharpley's (ans3@psu.edu) work on P dynamics. He is now at the USDA-ARS Pasture Laboratory in University Park, PA. Jay Dorsey (jdorsey@soils.umn.edu) is involved in an on-farm investigation of how management intensive grazing affects indexes of sustainability, among which are soil nutrient status, bird populations, stream insect diversity, etc. A nice review article was written by Haynes and Williams (Advances in Agron. 49). There are several papers on excreta distribution (Peterson et al., Agron. J. 48:440 and 444; Richards and Wolton, J. Brit. Grassland Soc. 31:89; West et al., 1989, Soil Sci. Soc. Am J. 53:784). Afzal and Adams (Soil Sci. Soc. Am. J. 56:1160) found that inorganic N concentrations were as different between samples taken 10 cm apart as samples taken at larger distances. Conclusion: You can't take enough samples to characterize 50-acre pastures. Take John Sloan's advice and concentrate on small areas for detailed sampling. If possible, measure runoff from large areas, and try to predict those P losses from fine-scale measurements. Best of luck in your sampling.

Date: Thu, 6 Mar 1997 12:34:10 -0500 From: "Richard E. Woodward" <rwoodward@MINDSPRING.COM> Subject: Microbe population measurement Greetings! from Dick Woodward with Sierra Evironmental Services, Inc., Houston, TX. I am microbiologist specializing in industrial microbiology applications. I am interested in participating in this list because many of my projects involve bioremediation of soils. In addition to the usual hydrocarbon remedial actions, recent clean ups have focused on a mixed glycol spill and a nonylphenol (estorgen disrupter) spill. I routinely conduct treatablity studies to identify soil factors that are limiting microbial growth then design a treatment system for field implementation. I am particularly interested in how people monitor changes in soil microbial populations and would be interested in starting a thread on this topic. I am currently using an instrument "borrowed" from the metal working industry, to provide real-time measurement of soil microbe populations. For the interest of the group: HMB IV REPLACES PLATE COUNTS The portable, hand-held HMB IV measures the population of aerobic microorganisms in soils in 30 minutes. The battery operated unit provides near real-time measurements of microbe population densities for effective process control of bioremediation in the laboratory (treatability studies) and in the field. The data can define population trends for process control, verify the effect of nutrients and adjuvants, and evaluate the toxicity of candidate treatment materials. The assay measures only viable, vegetative biomass, so spores and resting structures that distort the traditional MPN/ plate count technique are excluded. Because the instrument can test water, mixed liquor, sludge and soils, the microorganism population is measured in its own medium. The HMB IV was recently featured in Water World, Water Technology News and Environmental Solutions Product Guide. Case studies featuring various applications have been presented at ASM, ACS and WEF conferences. If you are interested in near real-time data on microbial population dynamics in soils, send me your snail mail address. I'd be pleased to share my experiences with the HMB IV.

Votes must be received by 23:59:59 UTC, 26 Mar 1997. This vote is being conducted by a neutral third party. Questions about the proposed group should be directed to the proponent. Proponent: Wolfgang Bujatti <sea-life@pacific-ocean.com> Mentor: Jonathan Grobe <grobe@netins.net> Votetaker: Jani Patokallio <jpatokal@alpha.hut.fi> RATIONALE: sci.environment.waste Keywords: waste management, hazardous waste, garbage, refuse, industrial waste, municipal solid waste, domestic refuse, source reduction, collecting and fractioning of wastes, waste processing, reuse, recycling, incineration, waste treatment, conditioning to inert them, waste disposal, composting, hazard potential for subsequent generations, greenhouse gases The increasing quantity and the hazards of wastes evolved to a very serious environmental problem. They can impair the general well- being of man, animals, vegetation, their basis of existence or their natural environment. Waste-related discussions are currently taking place on environmental newsgroups - particularly on sci.environment - but as this topic needs an integrated approch by environmentalists, biologists, ecologists, chemists, technicians and lawyers the Usenet community would be better served by a more specific forum. Moreover it would ease the traffic at sci.environment (about 30 postings a day). This newsgroup is proposed to provide a forum for scientific discussion on the one hand by people who are interested in the effects which their wastes can take on our natural environment (soil, water, air and the seas) and on the other hand by people involved in collecting, fractioning, processing, treating, recycling or dumping wastes or other waste management methods. This group is proposed as unmoderated group. A moderation should be the last precaution against off-topic posts, spam, or repetitive flaming (attacks). As this newsgroup has the aim to bring together very differnent groups of people it wouldn't be easy for a moderator to filter the postings to serve all. Sci.environment is an unmoderated group too. This group is not being created as sci.bio.ecology.waste, sci.engr.environment.waste or misc.legal.waste as it is intended to maintain a scientifically and factually based focus of all waste-related topics rather than a primarily opinion based focus nor an only specific biological, technical or legal talk. I've chosen the label waste instead of a more specific description (such as recycling or dumping) since this is the usual description for departements of administrations, non governmental organisations and enterprises. CHARTER: sci.environment.waste An unmoderated newsgroup which would provide a world wide forum for a serious discussion by people who try to reduce wastes, which are involved with collecting, fractioning, processing, treating, recycling or dumping wastes or with other waste management methods or people which treat them, so that they can reused for a different purpose, as well as by people, who are cronfronted with the dangers of wastes in everyday life. To assist governments, NGOs, environmentalists and scientists in the acquisition of scientific and legal waste-related information as well as an informative arena on the many different world wide techniques of conditioning, recycling and reusing wastes. Specific topics may include but are not limited to: + the many different types of wastes and their effection on the ecosystems in the soil, the rivers, the atmosphere and the seas and oceans + industrial and municipal solid waste (domestic refuse) + dumping (nowadays or in the past) of toxic wastes in landfill sites + sealing and watertighten of landfill sites and underground dumping sites + different world-wide skills and techniques of waste reduction in the production-process, of processing, treating, recycling and reusing wastes and other waste management methods + environmental impact of waste treating plants and landfill sites + pros and cons of waste incineration and the rank of its spent air + waste-to-energy + specific problems of transport of hazardous wastes on land, air and sea + pacticable collection systems + wastewater and sludges use, composting + reuse of tyres, waste-paper, packings, etc. + hazards of waste batteries, neon tubes, refrigerator-liquid, synthetics, etc. + greenhouse gases The following types of posts are strictly PROHIBITED in this newsgroup: * Material and advertisments unrelated to conditioning, recycling, and impact of wastes (off-topic) * Spam (defined as articles posted to more than 5 newsgroups) * Make-money-fast or other chain or fraudulent schemes * Forged posts (anonymous posts are allowed) * Personal insults or repetitive flaming (attacks) The use of e-mail addresses from articles posted to this group for the purpose of sending junk (mass unsolicited) e-mail or for compiling a list so that others may do so is specifically PROHIBITED. Binaries are only allowed by adding format or extension in the subject line. On-topic advertising and employment (help and/or position wanted) noticesis are limited to once per week. Please send such post only on fridays. Discussions about saving the nature without context to wastes should better take place on sci.environment or sci.bio.conservation, and the talk about energy-production (with the only exception of waste-to-energy discussion) and production techniques (with the only exception of waste reduction in the production-process) should better take place on sci.energy or on the sci.engr hierarchy. The general "netiquette" FAQs posted in news.announce.newusers and news.answers apply to the proposed group. Participants are encouraged to use descriptive Subjects (e.g., "Burning PCBs" rather than just "Help" or "Question"). In the absence of moderation, prohibitions can, of course, only be enforced by the collective will of the group and/or by after-the-fact complaints to the offender's service provider. END CHARTER. HOW TO VOTE: Follow these instructions *exactly*! Votes are counted by computer. You should send E-MAIL (posts to a newsgroup are invalid) to: voting@hut.fi Just replying to this message won't work. Check the address before you mail your vote. Your mail message should contain one and only one of the following vote statements: I vote YES on sci.environment.waste I vote NO on sci.environment.waste Voter name: If your mail software does not indicate your real name (for example, AOL and Delphi do not), include _exactly_ the statement above on a _separate_ line and add your name after the colon. Having your name in your signature line is NOT enough! Do NOT join the lines together or remove the words "Voter name"! You may also vote ABSTAIN (which does exactly that) or CANCEL (which removes any earlier votes). ABSTAIN does not affect the final vote count in any way but is listed, whereas CANCEL is not. IMPORTANT VOTING PROCEDURE NOTES: Standard Guidelines for voting apply. One person, one vote. Votes must be mailed directly from the voter to the votetaker. Anonymous, forwarded or proxy votes are not valid. Votes mailed by WWW/HTML/CGI forms are considered to be anonymous votes. Vote counting is automated. Failure to follow these directions may mean that your vote does not get counted. If you do not receive an acknowledgment of your vote within three days contact the votetaker about the problem. It's your responsibility to make sure your vote is registered correctly. Duplicate votes are resolved in favor of the most recent valid vote. Addresses and votes of all voters will be published in the final voting results post. The purpose of a Usenet vote is to determine the genuine interest of persons who would read a proposed newsgroup. Soliciting votes from disinterested parties defeats this purpose. Please do not distribute this CFV. If you must, direct people to the official CFV as posted to news.announce.newgroups. Distributing pre-marked or otherwise edited copies of this CFV is generally considered to be vote fraud. When in doubt, ask the votetaker.

Woodward" <rwoodward@MINDSPRING.COM> Subject: Re: Microbe population measurement Bob: We are doing some soil survey work with the HMB IV to locate petroleum reservoirs by identifying soils with elevated microbe populations. We have found a very strong positive correlation with other data (presence of hydrocarbon degrading heterotrophs, seismic, satellite and drilling) and elevated soil microbes over virgin (pressurized) deposits. The correlation weakens after the reservoir has been tapped and depressurized over time. Soil samples for the analysis were collected from the surface. I routinely use the HMB IV to monitor soil bioremeidation in transects across land treatment units. The HMB IV identifies areas with lower activity so I can do additional sleuthing and take corrective action. Frequently, the problem is ventilation (oxygen starvation due to soil saturation), however at one site low pH apparently increased the availability of some divalent cations (Cu, Mn and Zn) that supressed microbial growth. Liming corrrected the problem. Regards, Dick At 04:18 PM 3/7/97 -0600, you wrote: >Greetings from Bob Blaisdell.

I am Douglas Frink, not a soil scientist per se, but an archaeologist with the Archaeology Consulting Team, who views the soil as the primary context from which significant archaeological information can be found. As might be deduced, my primary interests in soils involve pedogenesis; that aspect of pedology which views the growth of the soil over time. For my one "Burning" topic I would like to invite the Soils-List members to visit the new OCR Carbon Dating web page. The OCR procedure is a chemical (not radiometric) means for determining the age of organic carbon (both charcoal and humus) within the soil context. The web site contains past publications augmented with recent data, and has been developed to increase exposure and discussion of these findings. Douglas

California) I've been reading the list for several years; I'm working on propagating native grasses from the 5000' elevation Ca. Coast Range, replanting sites that have lost about a foot of topsoil in the past century (so the Nat'l. Forest hydrologist with long experience up there tells me). I've realized we're trying to propagate soil, basically -- starting from the half inch or so of A-horizon remaining, some deeper pockets, and a lot of square meters of fine gravel surface with very fine black silt below the top, and isolated bunchgrasses standing on pedestals their roots are holding. I've gotten soil microbiology samples done at OSU Corvallis for baseline, put about 600 plants in, and have 12,000 more in a seed farm planting for a seed increase (from a pound of hand-collected seed last year). I'm very curious to know if anyone's worked on inoculating soil into gravel/sand/mulch piles, trying to propagate the micro-biota that are currently on the site. And whether there's much chance what's living in the remaining soil will be at all close to what supported the original soils there. We're not expecting to "restore nature" -- just to keep from losing that last half inch, hold off the Medusahead grass and other fire-prone invasives, and get baseline info so over time, whatever does establish there can be tracked and perhaps helped along. I figure it's a 200-year project.

The GEOSEA Congress is held triennially in Southeast Asia and it offers an excellent opportunity to exchange scientific and technical information among earth scientists from within and outside the region. The GEOSEA Congress is a premier event in the region and has been well attended by the scientific community worldwide. Southeast Asia is a dynamic region which is growing rapidly and is anticipated to be an economic force by the turn of the century. Earth sciences play a crucial role in sustaining this drive towards development. In appreciation of this fact, "Earth Science in Support of Growing Southeast Asian Economies" is chosen as the theme of GEOSEA '98. The Congress is designed to highlight the important contribution of earth sciences in economic development to policy makers, decision makers and regulators. TOPICS To provide a forum for the discussion of current development and research activities the Congress will focus on geology, petroleum geology, economic geology, engineering geology, environmental geology, geoscience education, tectonics, structural geology, geochemistry, geophysics, petrology, stratigraphy, sedimentology, mineralogy, paleontology and other aspects of earth science that is relevant to the Southeast Asian region. CALL FOR PAPERS Keynote address by invited speakers on topics of relevance to the theme and of special interest to the Southeast Asian region are planned. The programme includes oral and poster presentations. Papers on original research related to the topics above are invited for consideration. =46IELDTRIPS In conjunction with GEOSEA '98 the following fieldtrips are planned. Details of these fieldtrips will be given in the next circular.

It seems that this topic has been studied by researchers in every field related with soils.

Date: Thu, 20 Mar 1997 18:01:05 -0600 From: Michael Russelle <russelle@SOILS.UMN.EDU> Subject: precision farming of forages A few weeks ago, I asked people on the soils-l and forage-mg lists whether they had any information on the use of precision agriculture techniques relating to nutrient application on perennial forages. This is a summary of the responses I received. I cannot vouch for the accuracy of this information and no recommendation is implied in this listing; it is only as complete as those who took time to reply -- my thanks to each of you who did: Of course, some farmers have been practicing site specific farming of forages for years. As Dan Wiersma (dwiersma@facstaff.wisc.edu) pointed out, farmers in Wisconsin wanting legume hay will plant red clover in poorly drained areas and alfalfa elsewhere. But more intensive site specific management of nutrients on perennial forages does not appear to be widely practiced at the present. According to several respondents, there is little being done using this technology on forages in the Canadian Prairies, New Zealand, California, Wisconsin, Minnesota, western New York state, Oklahoma, Kansas, or Nebraska. A few exceptions and interesting ideas follow: 1) Use of site specific application of lime is being tested in Wisconsin, according to Dan Undersander (djunders@facstaff.wisc.edu). 2) Dan Wiersma reminded me that the planned regional dairy research center in Marshfield, Wisconsin, will likely be farmed using precision agriculture techniques. Land characteristics (field boundaries, soil characteristics, elevation, etc.) will be built into a GIS database for future use. 3) In New Zealand, Jim Crush (crushj@agresearch.cri.nz) and colleagues are planning to apply differential fertilizer P rates, depending on pasture plant species presence. It evidently requires 3x more P to keep white clover in a clover/perennial ryegrass mixture than for maximum yield of either in monocultures under their conditions. How variable rates will affect plant populations over time is unknown. 4) Chuck West (cpwest@comp.uark.edu) reported that Arkansas researchers and extension personnel are promoting precision application of livestock waste to avoid areas of high runoff potential. This has been based more on landscape features than soil test results to date. Location and management of rotational grazing is also being done in consideration of site specific characteristics. 5) According to Dan Putnam (dhputnam@ucdavis.edu), researchers in California have discussed the possibility of using site specific farming with alfalfa, but do think it will pay on their relatively uniform soils, considering the relatively low cost of P and K fertilizer. 6) Northwest Precision Ag (Blackfoot, Idaho, 208-785-5758) has just begun grid sampling alfalfa fields for macro and micronutrients and will begin detailed yield monitoring this year. They feel that the potential for profitability of site specific farming is likely higher with perennial crops that with annuals. One requirement of site specific farming is the need to monitor yields over the field to determine response to the variable input. Machinery for forages has been lacking, but some equipment has been developed recently: 1) Leonard Bashford (bsen052@unlvm.unl.edu), Univ. of Nebraska, has worked with a MS student to develop a baler with a yield monitor and GPS. They will present a paper on the work this summer at the Am. Soc. Agric. Engineers meeting in Minneapolis, MN. 2) Ag Tech Inc. and Technological Solutions International (tsi@initco.net) have developed a yield monitor for use in windrowers, and has equipment and software for site specific application of fertilizers and chemicals. TSI does not recommend grid sampling, but rather take many fewer samples and concentrate on sampling different landscape position, soil drainage, and other characteristics that will likely impact yield. 3) Kevin Shinners (kjshinne@facstaff.wisc.edu) and Ron Schuler (rschuler@facstaff.wisc.edu) have developed a forage harvester with yield sensors that will be field tested this year. 4) I have heard that New Holland has developed or is developing forage and manure application equipment to use with GPS, but found no information on their web page about it. That summarizes what I heard about in the past few weeks. Thanks, again, for your responses. If you know of any other use of precision farming approaches for fertilizer, livestock manure, or waste disposal on perennial forages, please contact me. Thank you.

Date: Fri, 21 Mar 1997 09:47:33 +0100 From: Bujatti Wolfgang <Wolfgang.Bujatti@BMU.GV.AT> Subject: 2nd CFV: sci.environment.waste - Deadline: 26 Mar 1997 SECOND AND FINAL CALL FOR VOTES unmoderated group sci.environment.waste Newsgroups line: sci.environment.waste Impact of Wastes and Waste Management Methods. Votes must be received by 23:59:59 UTC, 26 Mar 1997. This vote is being conducted by a neutral third party. Questions about the proposed group should be directed to the proponent. Proponent: Wolfgang Bujatti <sea-life@pacific-ocean.com> Mentor: Jonathan Grobe <grobe@netins.net> Votetaker: Jani Patokallio <jpatokal@alpha.hut.fi> RATIONALE: sci.environment.waste Keywords: waste management, hazardous waste, garbage, refuse, industrial waste, municipal solid waste, domestic refuse, source reduction, collecting and fractioning of wastes, waste processing, reuse, recycling, incineration, waste treatment, conditioning to inert them, waste disposal, composting, hazard potential for subsequent generations, greenhouse gases The increasing quantity and the hazards of wastes evolved to a very serious environmental problem. They can impair the general well- being of man, animals, vegetation, their basis of existence or their natural environment. Waste-related discussions are currently taking place on environmental newsgroups - particularly on sci.environment - but as this topic needs an integrated approch by environmentalists, biologists, ecologists, chemists, technicians and lawyers the Usenet community would be better served by a more specific forum. Moreover it would ease the traffic at sci.environment (about 30 postings a day). This newsgroup is proposed to provide a forum for scientific discussion on the one hand by people who are interested in the effects which their wastes can take on our natural environment (soil, water, air and the seas) and on the other hand by people involved in collecting, fractioning, processing, treating, recycling or dumping wastes or other waste management methods. This group is proposed as unmoderated group. A moderation should be the last precaution against off-topic posts, spam, or repetitive flaming (attacks). As this newsgroup has the aim to bring together very differnent groups of people it wouldn't be easy for a moderator to filter the postings to serve all. Sci.environment is an unmoderated group too. This group is not being created as sci.bio.ecology.waste, sci.engr.environment.waste or misc.legal.waste as it is intended to maintain a scientifically and factually based focus of all waste-related topics rather than a primarily opinion based focus nor an only specific biological, technical or legal talk. I've chosen the label waste instead of a more specific description (such as recycling or dumping) since this is the usual description for departements of administrations, non governmental organisations and enterprises. CHARTER: sci.environment.waste An unmoderated newsgroup which would provide a world wide forum for a serious discussion by people who try to reduce wastes, which are involved with collecting, fractioning, processing, treating, recycling or dumping wastes or with other waste management methods or people which treat them, so that they can reused for a different purpose, as well as by people, who are cronfronted with the dangers of wastes in everyday life. To assist governments, NGOs, environmentalists and scientists in the acquisition of scientific and legal waste-related information as well as an informative arena on the many different world wide techniques of conditioning, recycling and reusing wastes. Specific topics may include but are not limited to: + the many different types of wastes and their effection on the ecosystems in the soil, the rivers, the atmosphere and the seas and oceans + industrial and municipal solid waste (domestic refuse) + dumping (nowadays or in the past) of toxic wastes in landfill sites + sealing and watertighten of landfill sites and underground dumping sites + different world-wide skills and techniques of waste reduction in the production-process, of processing, treating, recycling and reusing wastes and other waste management methods + environmental impact of waste treating plants and landfill sites + pros and cons of waste incineration and the rank of its spent air + waste-to-energy + specific problems of transport of hazardous wastes on land, air and sea + pacticable collection systems + wastewater and sludges use, composting + reuse of tyres, waste-paper, packings, etc. + hazards of waste batteries, neon tubes, refrigerator-liquid, synthetics, etc. + greenhouse gases The following types of posts are strictly PROHIBITED in this newsgroup: * Material and advertisments unrelated to conditioning, recycling, and impact of wastes (off-topic) * Spam (defined as articles posted to more than 5 newsgroups) * Make-money-fast or other chain or fraudulent schemes * Forged posts (anonymous posts are allowed) * Personal insults or repetitive flaming (attacks) The use of e-mail addresses from articles posted to this group for the purpose of sending junk (mass unsolicited) e-mail or for compiling a list so that others may do so is specifically PROHIBITED. Binaries are only allowed by adding format or extension in the subject line. On-topic advertising and employment (help and/or position wanted) noticesis are limited to once per week. Please send such post only on fridays. Discussions about saving the nature without context to wastes should better take place on sci.environment or sci.bio.conservation, and the talk about energy-production (with the only exception of waste-to-energy discussion) and production techniques (with the only exception of waste reduction in the production-process) should better take place on sci.energy or on the sci.engr hierarchy. The general "netiquette" FAQs posted in news.announce.newusers and news.answers apply to the proposed group. Participants are encouraged to use descriptive Subjects (e.g., "Burning PCBs" rather than just "Help" or "Question"). In the absence of moderation, prohibitions can, of course, only be enforced by the collective will of the group and/or by after-the-fact complaints to the offender's service provider. END CHARTER. HOW TO VOTE: Follow these instructions *exactly*! Votes are counted by computer. You should send E-MAIL (posts to a newsgroup are invalid) to: voting@hut.fi Just replying to this message won't work. Check the address before you mail your vote. Your mail message should contain one and only one of the following vote statements: I vote YES on sci.environment.waste I vote NO on sci.environment.waste Voter name: If your mail software does not indicate your real name (for example, AOL and Delphi do not), include _exactly_ the statement above on a _separate_ line and add your name after the colon. Having your name in your signature line is NOT enough! Do NOT join the lines together or remove the words "Voter name"! You may also vote ABSTAIN (which does exactly that) or CANCEL (which removes any earlier votes). ABSTAIN does not affect the final vote count in any way but is listed, whereas CANCEL is not. IMPORTANT VOTING PROCEDURE NOTES: Standard Guidelines for voting apply. One person, one vote. Votes must be mailed directly from the voter to the votetaker. Anonymous, forwarded or proxy votes are not valid. Votes mailed by WWW/HTML/CGI forms are considered to be anonymous votes. Vote counting is automated. Failure to follow these directions may mean that your vote does not get counted. If you do not receive an acknowledgment of your vote within three days contact the votetaker about the problem. It's your responsibility to make sure your vote is registered correctly. Duplicate votes are resolved in favor of the most recent valid vote. Addresses and votes of all voters will be published in the final voting results post. The purpose of a Usenet vote is to determine the genuine interest of persons who would read a proposed newsgroup. Soliciting votes from disinterested parties defeats this purpose.

I am currently taking my first soils class and find it very enjoyable. I enjoy it enough to have volunteered to assist in a research project. The research project involves the comparison of two different types of soil water samplers, the porous ceramic cup type and the teflon and steel type. The brands that are being used are Soilmoisture and Prenart, respectively. I was wondering if anyone had performed research with these two different types of lysimeters before and had found any differences in any of the areas that are involved with using them, such as; cleaning, installation, and test results. I have conducted some library research, but have yet to come up with anything that would be geared towards what I am doing. Any help with this would be greatly appreciated. Also I am looking for any information on a bulk density sampler that is or was made by a company named Uhland. If the name has changed or the sampler is being produced by a different company, I'd appreciate any information on that. Thanks for your time in advance and if I made any dumb mistakes with this, please excuse them, my computer skills are in the Fred Flintsone category. Waiting for winter to end, Grant Delaware Mistake #1: I brilliantly forgot to leave my address. It is GDELAW61@Mail.Caps.Maine.Edu. Thanks.

At AgResearch we have developed fertiliser recommendation software specifically for pastoral agriculture in New Zealand. The Outlook (TM) decision support software has been designed for the evaluation of P and S fertiliser strategies by farm consultants in conjunction with their farmer clients. The software is licensed to farm consultants through the AgResearch Soil Fertility Service. The underlying dynamic model is based on the P and S cycles in the soil-plant-animal system, including fertiliser inputs and soil and animal mediated losses. Initial soil fertility is estimated from the Olsen P and phosphate extractable organic S soil tests, and recent fertiliser history. In the sulphur submodel organic S, sulphate and elemental S pools are considered. Animal production responses to fertiliser are estimated from relationships between soil P and S status, fertiliser inputs, relative pasture yield and stocking rate. Maintenance and economically optimum fertiliser strategies can be automatically calculated or the user can enter their own scenarios. Alternative fertiliser policies can be evaluated in terms of nutrient budgets, soil P and S status, pasture and animal production, and economics.

Quick" <dquick@ZOO.UVM.EDU> Subject: Re: fraudulent letter (fwd) Fraudulent Chain Letter This statement may be copied or reprinted by online users The American Cancer Society is greatly disturbed by reports of a fraudulent chain letter circulating on the internet which lists the American Cancer Society as a "corporate sponsor" but which has in no way been endorsed by the American Cancer Society. This letter appears to have started on America Online but has now spread well beyond the online service. There are several variations of this letter in circulation. The text of the original message reads as follows: LITTLE JESSICA MYDEK IS SEVEN YEARS OLD AND IS SUFFERING FROM AN ACUTE AND VERY RARE CASE OF CEREBRAL CARCINOMA. THIS CONDITION CAUSES SEVERE MALIGNANT BRAIN TUMORS AND IS A TERMINAL ILLNESS. THE DOCTORS HAVE GIVEN HER SIX MONTHS TO LIVE. AS PART OF HER DYING WISH, SHE WANTED TO START A CHAIN LETTER TO INFORM PEOPLE OF THIS CONDITION AND TO SEND PEOPLE THE MESSAGE TO LIVE LIFE TO THE FULLEST AND ENJOY EVERY MOMENT, A CHANCE THAT SHE WILL NEVER HAVE. FURTHERMORE, THE AMERICAN CANCER SOCIETY AND SEVERAL CORPORATE SPONSORS HAVE AGREED TO DONATE THREE CENTS TOWARD CONTINUING CANCER RESEARCH FOR EVERY NEW PERSON THAT GETS FORWARDED THIS MESSAGE. PLEASE GIVE JESSICA AND ALL CANCER VICTIMS A CHANCE. IF THERE ARE ANY QUESTIONS, SEND THEM TO THE AMERICAN CANCER SOCIETY AT ACS@AOL.COM As far as the American Cancer Society can determine, the story of Jessica Mydek is completely unsubstantiated. No fundraising efforts are being made by the American Cancer Society in her name or by the use of chain letters. Furthermore, the email address ACS@AOL.COM is inactive. Any messages to the American Cancer Society should be instead sent through the American Cancer Society website at http://www.cancer.org. This particular chain letter with its heartbreaking story appears to have struck an emotional chord with online users. Although we are very concerned that the American Cancer Society's name has been used to manipulate the online public, we applaud the good intentions of all who participated in this letter. We are pleased to note that there are so many caring individuals out there and hope that they will find another way to support cancer research. Jessica Mydek's story, whether true or false, is representative of that of many cancer patients who benefit daily from the efforts of legitimate cancer organizations nationwide.

This horizon contains organic carbon (and organic matter) of different ages. In general, the calculated constant is based on the mean of all these different aged carbons. A vast difference in the constant can be found between fresh organic matter, a well evolved A-horizon, and a buried paleo-A horizon.

Date: Thu, 27 Mar 1997 10:37:52 -0800 From: Rob Harrison <robh@U.WASHINGTON.EDU> Subject: Re: Relationship between OC & OM Richard; Theoretically, anything that can accept an electron could take the role of oxygen as your described. However, there are only a few chemical species that commonly do this in soils and water. These include nitrate, sulfate, manganese, iron, hydrogen, and carbohydrates. The energetic sequence of electron acceptors following the elimination of gaseous oxygen from a submerged soil, for instance, are as follows. They will not necessarily follow in this order in reality, since some are solid-phase (Manganese oxide), some are typically dissolved in water (sulfate), and some are gaseous or dissolved in water (oxygen). Gaseous or dissolved electron acceptors can move around by diffusion, whereas solid-phase species force microbes to move to them. I'm not sure whether or not elemental sulfur will be reduced in an anoxic soil. Theoretically, it could be, but I have not encountered this happening. It certainly oxidizes in the presence of gaseous oxygen, and is often used to acidify soil in this way. Once it is present as sulfate, it is often an important electron acceptor in anaerobic soils as shown below. Rob Harrison Suggested readings include: Ponnamperuma, F.N. 1972.

In Italy we use 1.724 only because it is the same number applied by official analytical methods for organic fertilizer. There is not a correct number (or a magic number). Remember also that generally it is used a correction factor for the organic carbon not recovered. It ranges from 1.19 to 1.33. See: D.W. Nelson and l.E. Sommers. 1982. Total carbon, organic carbon and organic matter. p. 539-579 In: Page A.L., R.H. Miller e D.R. Keeney (ed.). Methods of soil analysis, Part 2. Chemical and microbiological properties 2=AA ed.
