Subject: Re: Microbe population measurement
Gerhard, Thanks for your interest in the HMB IV. I have sent a package of
information for your review via snail mail.
There is a considerable amount of work in progress evaluating soil microbe
populations with the HMB IV. One of the most interesting involves a project
with the Mississippi State Geologist, Jack Moody. Jack is interested in
identifying hydrocarbon deposits in the state using non invasive methods.
His program as included remote sensing (a joint project with NASA), some new
electronic technology and evaluation of surface samples for enhanced microbe
populations above hydrocarbon deposits. In every case we have examined,
there is a dramatic increase in the total microbe population above virgin
reservoirs. Above producing reservoirs the correlation is less intense but
an elevated population is still present. Jack is presenting a poster
session of his work at the Society of Petroleum Geologists meeting in Dallas
the end of this month. I may be able to provide you with an abstract if you
are interested. I think the method will be enbrace by E&P companies because
if allows for the analysis of many samples directly, in the field.
Traditionally, exploration has been under sampled because fo the cost of
shipping and processing samples in the laboratory.

Many of the traditional methods of enumeration tend to underestimate the
actual population. I conducted some comparative studies several years ago
by evaluating Acridine Orange Direct Count (AODC) vs. traditional plate
count techniques. The AODC reported more that two orders of magnitude more
organisms!
The HMB is based on an enzyme assay and the results were consistent with the
AODC method. Your observations may be a function of your test method.

Subject: FYI: fraudulent cancer patient chain letter (fwd)
Just thought everyone should know, in case you're thinking of sending the
chain letter you'd just received onward. The following is a statement
from the American Cancer Society regarding the fake chain letter.
______________________________________________________________________________
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.

1. k facor
Date: Sat, 5 Apr 1997 11:28:23 -0500
From: Jscott6615@AOL.COM
Subject: k facor
Hi
Alan Peer, Project Leader, from the Jasper County Missouri Soil Survey has
asked me to submitt the following from him:
K factors
The Soil Erodibility Nomograph (USDA - Natural Resources Conservation
Service's Agricultural Handbook 537) is used to compute K factors.
The equation in the USDA - Natural Resources Conservation Service's
National Soils Handbook page 618-37 shows the following equation to
figure the K factor: K factor = {2.1 X M to the 1.14 power X 10 to the
minus 4 power X (12 - a) + 3.25 X (b - 2) + 2.5 X (c - 3)}/100; where
M = (percent si + percent vfs) X (100 - percent clay) and a = percent
organic matter, b = structure code, and c = profile permeability
class.
This equation fits the nomograph curve for vfs + si values of less
than about 67 percent. The curve changes at that point and no
equation for the rest of the curve for values of vfs + si greater than
67 percent.
Gerald Crenwelge, USDA, NRCS Lubbock, TX, has developed a program
written in QWBasic to compute the K value from lab and pedon data.
However, this does not work with values of vfs + si above 67 percent.
He is going to extrapolate the formula for values greater than this
and integrate this into the program.
Is the equation already in some literature so that it does not have to
be extrapolated?
There is some indication that the formula does not really fit the
nomograph. Is this true?

From: Ginger Paige <ginger@TUCSON.ARS.AG.GOV>
Subject: Re: k factor
I don't have any direct experience with determining the K factor, so I asked
a collaborator to check the calculations of the K factor in RUSLE. Here is
what he found.
I checked RUSLE v105 to see if it would calculate a K for a soil with 92%
vfs and silt and it did. However, there is nothing in the documentation
saying how it is done. Also, the documentation does state that the
nomograph is good for soil with less than 70% vfs and silt. Matt Romkens
(ARS in Oxford) is the
lead author of the K section of RUSLE. You might give him a call to see
what was done to extend the nomograph.

1. Help -- UK chalk soil properties
Date: Wed, 9 Apr 1997 11:06:47 -0400
From: Byron Bodo <bodo@INTERLOG.COM>
Subject: Help -- UK chalk soil properties
Am trying to find some general info on UK chalk soil. In the course
of some reading on hydrology and NO3 contamination of groundwater,
I found contradictory claims suggesting that the UK chalk soils are
both permeable and impermeable.
I'm not even sure what chalk soil is as we don't seem to have
any in these parts. Just guessing that's it's a cousin
of marl & has very high CO3 content.
Would much appreciate, if someone could give me the $0.25 quick
study.
TIA

Byron:
The state of Mississippi and Alabama have chalk deposits that have been
studied for the use of containing hazardous wastes. I suggest that you
contact the Hazardous Waste Division of the Mississippi Dept. of Envir.
Quality at 601-961-5171 or the Mississippi Geological Survey at
601-961-5500.
I think you will find out that your chalks and ours are of the same
period (Cretaceous) with similar hydrologic properties. Since chalk is a
variant of limestone, I also suspect that this property could vary
depending on the location (like limestone).

Date: Tue, 15 Apr 1997 10:16:33 +0900
From: David Mussared <mussared@WEBMEDIA.COM.AU>
Subject: 'Land and Water News' (Australian interest only)
(apologies for cross-postings)
Dear All
This email is to announce the launch of a new Australian publication,
called 'Land and Water News'. The first issue was published today.
'Land and Water News' is an independent, national roundup of breaking news
in the Australian land and water field. It is a quality newsletter aimed at
business, government and research professionals working in the area.
Each month (except January), 'Land and Water News' will report on new
developments in Federal and State Government policy and legislation;
funding arrangements; business news; research updates; relevant public
debates; local government issues; and key reports, reviews and
publications.
'Land and Water News' is entirely independent. It accepts no advertising,
and is not funded by any agency nor organisation. The newsletter is
available only by paid subscription, which costs $220 a year.
For a complimentary copy (including subscription details) please contact
the editor, David Mussared. Contact details are:

-----------------------------------------------------------------
For more information about 'Land and Water News', please read on:
Compare our price
-----------------
At $220 a year, 'Land and Water News' is cheaper than most daily newspaper
subscriptions. It is devoted entirely to accurate, high-quality reporting
of interest to professionals in the field.
At $220 a year, 'Land and Water News' is a fraction of the price of a
commercial newspaper clipping or media monitoring service. It is posted to
you as an executive summary of important developments.
At $220 a year, 'Land and Water News' is far cheaper than employing your
own media consultant to keep tabs on public issues which affect your work.
The next issue: Federal Budget analysis
---------------------------------------
The next issue of 'Land and Water News' will be published shortly after the
May 13 Federal Budget, and will include a detailed analysis of the Budget's
impacts on natural resource and environment issues throughout Australia.
What's in it for you?
---------------------
Subscribing to 'Land and Water News' is like having your own, personal
media consultant chasing up issues which are important to you, and
delivering a monthly summary of new developments.
Because 'Land and Water News' is financially independent, it can report
critically on hot issues. It draws on an extensive network of inside
contacts, as well as published and unpublished information from many
sources, to tell you what is really going on - not just the official
version.
A subscription to 'Land and Water News' will arm you with a monthly
intelligence report, at a glance. It will dramatically reduce the amount of
reading you need to do to stay abreast in this rapidly changing area.

I'm at present Project Researcher at the University of Leuven (Belgium),
Department of land management.
I'm getting a phd thesis on the 24th april (not yet!). Studied the sorptive
capacities of phosphate saturated soils (Langmuir, kinetics of 32P exchange),
studied more particularly the phosphate availability in solution of a
temporarily submerged mineral field.
Present interest field: the same but the aim is to model the 1D P transport in
the vadose zone, special problem:
1. leaching possibilities in very saturated soils for P (livestock, manure...)
2. Fate of organic P (mineralization-immobilization)
3. colloidal transport of P

The following are goals of the symposium :
Advances in soil survey using modern tools: methods and results
This symposium is intended for researchers with some background or
knowledge of the information available in the soil survey program, and who
have an interest in increasing their knowledge of the application of the
soil survey data. The symposium seeks to explore a rapidly developing
field in which new tools have been developed to better study and use soil
survey data while observing soils in the field, characterizing soil
landscapes, determining and analyzing soil variability, and developing
models to characterize the spatial variability of soils. The objective of
the symposium is to present how modern tools or the application of new
theoretical approaches contribute to a refined spatial analysis and
knowledge of soil variability. =BB
New tools of soil characterization are first considered. Conventional
methods of observing soils have generally been slow and tedious, and often
result in a limited number of observations over a small area. Individuals
are requiring more accurate and site-specific data on soil properties and
variability of soils at greater depths than previously attained in soil
surveys. To fulfill the need for deeper and more intense sampling, precise
methods of observing soils are required.=20
Participants will learn about new developments in geophysical methods that
are helping to increase the application of tools such as the
ground-penetrating radar, magnetometers, electrical conductivity equipment,
infrared detectors, and other remote sensing techniques. New laboratory
equipment as well field equipment will be discussed. Systematic sampling
using geophysical methods and computer graphic techniques can enhance and
develop a better understanding of soils and the landscapes on which the
soils occur. Problems related to the lack of quality soil data and the
limited quantity of data related to the application of soil surveys in
Geographic Information Systems (GIS) will be explored and evaluated.. The
ability to use new tools and technologies can result in rapid, reliable
interpretation of soils data on site. =20
The interest for soil spatial analysis of an evolutive theoretical
background in such areas as artificial intelligence, geostatistics, fuzzy
logic, and mathematic modeling will be presented. The interest of coupling
soil observations with topographic parameters derived from Digital
Elevation Models will also be considered for soil spatial variability
modeling. =20
Modeling data from the theoretical background can be very useful in helping
to understand field data, and in helping to solve field problems. This
symposium will stress the need to use and interpret quality field data and
illustrate the features and limitations of modeling the field data. =20

I have been off of the list for a couple of months because of network
problems. I was wondering if anything new has been discussed about the
use of polyacrylamide emulsions for soil stabilization?

Subject: Contacts in Turkey ?
My name is Richard MacEwan. I lecture in soils, hydrology and land
rehabilitation at Ballarat University, Australia.
I am planning to be in Turkey to attend a symposium in Istanbul at
the beginning of September. I am interested in making contact with
any soil scientists in Turkey who would be able to show me what is
happening in the soil management / land rehabilitation area. Anyone
out there? I will have a week to spare either at the end of August or
second week of September.
Regards.
Richard

Hi to Soil-L'ers!
I just joined this interesting listserv group. I am doing a Geography M.A.
Thesis in regard to the soils of Utah, Idaho and Wyoming.
What I am looking for:
the soils classification data
any articles or books devoted to the certain soils
The locales I am covering:
Abraham, Millard County, Utah (near Delta)
Location: 39 23 48 N, 112 43 02 W (coordinates)
Elevation: 4591
Vocation, Park County, Wyoming (near Cody and Powell)
Location: 44 39 48 N, 108 56 34 W
Elevation: approximately 3900-4300 feet (?)
Eden and Hunt, Jerome County, Idaho (near Twin Falls)
Location: 42 40 42N, 114 14 57 W
Elevation: approximately 4600 feet
I did make field trips to the three places above. From what I gathered,
the Abraham soil appears to be alkalai (alkaline) while the Vocation and
Eden soils looked like loam soil. If I am correct, alkalai soil is more
loose than loam soil. Any comment?
From what I read, there was confusion on the nature of the soil in the
Abraham area: dust or sand. So would it be correct to call alkalai soil
"dust", not "sand"?
What I would like to know the most is whether alkalai and loam soil is
dangerous to inhale, particularly from dust storms. From what I have read,
there were frequent duststorms in those three areas. I would want to know
what it was like to have such soil in the body (mouth, eyes, ears, inhaling).
I have found data on dust and respiratory/lung diseases linked but they
are mainly confined to coal miners and mines.
Any help would be welcome! Cheers, Mr. Newby Ely
