Subject: Chemical residues in compost
I would appreciate any help you might be able to give in answereing this
question from a local (North texas) backyard composter:
"We use a popular horse worm medicine called Zimecterin (Ivermectin) Paste
1.87%. Does the active chemical in this worm medicine persist in compost
whose food stock includes manures from horses doctored with this substance?"
This product is distributed by the Farnam Companies in Phoenix.
I would add that these folks who ask this question are wonderful organic
farmers and would deeply appreciate any help you could provide.
Thanks in advance for your consideration.

Subject: conference hunting
Hi Friends
I am currently involved in a project on the relationship between erosion
and slope vegetation. The study focuses on the roles of a pine forest on
erosion control and slope stabilization in a gorge. I have been hunting
a conference in which I could introduce the preliminary result of
this study and share some idears with other colleages. A very intereting
conference called 'VEGETATION AND SLOPE STABILIZATION' has been hold in
Oxford, UK, last September. Is anybody know any information about the
coming-soon conference of this kind or similar? I would be appreciated
very much if he or she could offer me the information.
Thank you very much for your friendly help!

There is a lab in Germany that made a lot of research in compost-quality
and organic farming which maybe can help to get informations about
persistence of organic residues (medicine) in compost:

phone: +49 5542 981565, fax: +49 5542 981568
The knowledge about persistence of organic residues in compost is very
poor in general. Unfortunately a lot of researchers dealing with compost
are publishing in very small journals. So, if anybody has some brand new
results, it could be interesting to hearing about that here.

Subject: Soil moisture modeling
Currently I'm a graduate student at the Environmental Change Unit,
University of Oxford. As part of masters thesis I'd like to model the
effects of projected climate change on agricultural output in the Imperial
Valley, California. I need some advice on modeling soil moisture and
evapotraspiration in extreme conditions. If anyone has any experience in
this area I'd like to ask:
1. What models have been developed to predict the effects of
climate/temperature on irrigation? Have irrigation models been developed
that can be used for this sort of study?
2. What soil and/or crop models deal well with heat stress and drought?
I'll be in El Centro over Christmas. If anyone on this list lives in the
Imperial Valley or San Diego County areas please let me know. I'd like to
discuss these issues further with someone working in the area.
Thanks,

Hallo to all!
I have a question concerning aqua regia in soil analysis:
Does someone on the list have an idea about the theory and background
for analysing soil nutrients in aqua regia. It is the macro- and
micro soil- cations that I have analysed in a project concerning
forest soils, but I need some more information of how, and why this
strong acid is used for analysing soil samples and what fractions of
the cations is extracted.
I would be gratefull for any information or fx selected litterature
about the subject.

I am Patrick Coyle, a research chemist at Callaway Chemical Company.
Among other products our company makes a line of emulsion and solution
copolymers of acrylamide.
About two years ago Janet Roloff had an article in Science News
(Science News, Vol. 144, pgs 280-1) about using polyacrylamide to halt
soil erosion in irrigated fields. Always on the lookout for possible
new markets for our products, I did some literature searching, but
could only find some articles dating back to 1986 in Soil Science.
Unfortunately, I got tied up in some other things and didn't have a
chance to follow-up at that time.
Is anyone still working on this type research? If so, I would be
interested in getting some pointers to some literature sources or
possibly contact with a researcher.

Subject: Fertilizer N reducing the rate of OM mineralization
Some results from a laboratory incubation I did have shown that adding
N fertilizer decreased the rate of N mineralization from mushroom
compost amended soils. I am aware of other work that has found added
N may reduce the rate of organic matter decomposition (i.e. reviewed
by Kare Fog in Biological Reviews 1988, 63:433-462). This latter work
is mainly on organic materials with high C:N ratios and lignin contents,
and low N contents. In contrast mushroom compost has a C:N of 18
and contains 1.8% N, however the organic N it contains is resistant to
mineralization. Has anyone found similar results to these with composts
or other organic materials of similar quality ???

From: M.Turner@massey.ac.nz (Max Turner )
Subject: Looking for collaborators
Dear Listers
I would like to use the list for something a little different and I hope you
can assist me in my search.
I am looking to identify a small group of Soil Science lecturers (especially
in the soil fertility/fertilisers/land use areas) from a number of
different, english speaking countries. Probably some of the people I need to
know are not even current subscribers to this list, in which case you may be
able to assist me by mentioning this note to the appropriate person(s).
What I am looking to do is to offer these potential collaborators an
opportunity to participate in an exciting international educational
opportunity (details of which I am happy to elaborate once an expression of
interest has been received).
I hope to make contact with a global group of soils lecturers who are as
enamoured as I am with the use of the computer as an educational tool. If
you are of like mind then please contact me and acquaint me with your
interest in participating, together with your skills and special area of
expertise in Soil Science. For those with an interest in cooperation, but
who possess limited computer skills, I am prepared to do much of the
development work if your area of special interest is appropriate to the
project; so lack of computing skills need be no deterrent.
All told I hope to identify at least 10-12 enthusiastic lecturers, teaching
students at around the 300-400 level soils (ie students with at least some
basic understanding of how soils work) or at the post-graduate level, from a
number of different countries and climates. If this sounds interesting to
you please take the time to contact me at Massey University (in New
Zealand). Incidentally this initiative has the support and backing of the
Professor of Soil Science (Prof Russ Tillman), the Dean of the Agricultural
and Horticultural Faculty (Prof Robert Anderson) at Massey University, so it
is a legitimate undertaking.
I look forward to hearing from you if you wish to be involved.
Sincerely
Max Turner
(Senior Lecturer in Soil Science)

Subject: Re: CO2 Emissions
In reply to Patrick Joyce, concerning the rates of wasteage and CO2
emissions as organic matter is lost from a soil. He doesn't tell us the time
scales he's interested in, but my interest in this topic involves time
scales on the order of 100-10,000 years.
When an A horizon becomes buried, and therefore removed from additions of
carbon from decaying organisms, etc., it begins to lose organic carbon. In
the following three studies, organic carbon in buried soils was compared
with that of a nearby, surface A horizon that was not buried. In all three
studies, burial was caused by anthropogenic factors.
Hallberg et al. (1980) Proc. Soil Sci. Soc. America 42:339-343
Time of burial: 100 years beneath spoils from railroad cut
Carbon content of surface A: 2.6%
Carrbon content of buried A: ca. 1.5%
Loss: 42%
Mattingly and Williams (1962) J. Soil Sci. 13:254-258
Soil buried 1500 years under Roman amphitheater
Buried A: .77-.8% organic carbon
Surface A: 2.4%
Loss 68%
Gardiner and Walsh 1966 Proc. Royal Irish Acad. 65C:29-35
Soil buried 4000 years under burial mound
Buried A: 1.1%
Surface A: 4.9%
Loss: 78%
My impression is that the rate of decay is greatest in the first 100 years
following burial, but then begins to become more gradual. Organic carbon
bound tightly with clays would be the last to be lost, and can stay around
for 10s of thousands of years.
My literature on this subject is very out-of-date. Maybe others on the list
can add some more recent sources. I'd be interested in hearing them.

I am looking to talk with people that are in the bioremedation of petroleum
cantaminated soils.
Thank you

Peter,
Bioremediation of petroleum contaminated soils has proven to be an effective
remediation technology. It is however, not suitable for all soil types or
for all types of petroleum products. As with any remediation technology,
there are limitations which must be examined prior to implementation to
ensure that remediation goals are met. There are many good references on this
subject, and I would be happy to provide you with a list of references in you
desire.
I am employed by an environmental consulting firm and we have had very good
success bioremediating petroleum contaminated soils. I can provide some
actual data on the success of these projects if it will help you. Please
respond via e-mail.
Best Wishes,

Dear Mr Corey,]
I am aware of the general funtion and proccesses of bioremedation.
Currently I am working on an independant research project on a site near my
university and would like more information on the enzymatic processes
involved and techniques of isolating and identifying the different products
as the petroleum is being broken down.
I woul dlike some information on your company as I lived in that part of
Maine as a HIgh School student and would like to return someday if I could
find a job in this field.
Thanks for your time,
Peter Lawrence
