MidWest Plan Service News Release
The First International Conference on Air Pollution from Agricultural
Operations is set for February 7-9, 1996 at the Westin Crown Center in Kansas
City, Missouri. "The conference was planned by an 18-member international
committee in response to the need for information on measurement, estimation
and
control of agricultural emissions of odor, gases, dust and microorganisms,"
says
Al Heber, conference chair.
Sponsored by the MidWest Plan Service (MWPS), the conference will feature
both technical sessions and workshops to provide practical skills and applied
scientific information. "Emissions from area (wind erosion of soil, beef
feedlots),
enclosed (livestock buildings), storage (lagoons), handling (grain elevators)
and
moving point (harvesting, engine exhaust) sources will be addressed in 72
paper
presentations and 10 workshops," Heber notes. "Forty-five papers, three
workshops,
and two banquet speeches will be related to the technical and regulatory
issues
of LIVESTOCK ODOR. Most of the 41 papers and four workshops related to
livestock
buildings also pertain directly to INDOOR AIR QUALITY. Nine papers, two
workshops
and both keynote speakers will address GOVERNMENT POLICY. SOIL EROSION is a
topic in 14 papers and CROP HANDLING in 14 papers and five workshops. This is
a
unique opportunity for people working in these different areas to come
together
under a common theme."
Workshops cover sampling and control of dust, gases and microorganisms,
air
cleaning with cyclones and scrubbers, gas and particle physics, and
regulatory
compliance. Olfactometry equipment will be brought to the conference for an
odor
measurement workshop.
Keynote speakers Dr. Stan Meiberg, Director of the Air, Pesticides and
Toxics
Division of the U.S. Environmental Protection Agency Region 6 and invited
speaker Dr. Linda Rosenstock, Director of NIOSH, will kick off the conference
at
noon on Wednesday after several workshops that morning. Dr. Meiberg will
present
an overview of the EPA and its role in agriculture.
Dr. Rosenstock will address potential occupational health hazards from
agricultural air pollutants and how the conference theme falls under the
NIOSH
Farm Safe 2000 initiative. At the Thursday luncheon, Dr. John Sweeten of the
Department of Agricultural Engineering at Texas A&M University will kick off
the
technical sessions on odor. Dr. Cees van't Klooster of the Department of
Agricultural
Engineering at the DLO-Institute for Agricultural and Environmental
Engineering in
The Netherlands will provide the European perspective on pollutant emissions
from
enclosed sources at the Thursday evening banquet.
The conference is endorsed by the Northeast Regional Agricultural
Engineering Service (NRAES), the American Society of Agricultural Engineers
(ASAE) and the USDA Cooperative Extension Service. Attendees will include but
will not be limited to academic and industrial researchers; consulting
engineers
and scientists; educators; agricultural equipment and facilities designers;
air
pollution control equipment manufacturers; state regulatory officials; and
leaders
in related agricultural industries.

Apologies if you've already received this mail from the Quaternary
listserv...
I would be very very grateful for any advice concerning means of clay
dispersal.
I am in the process of obtaining size fractions by settling in a tube, using
filtered seawater as the settling medium. I cannot use distilled water as I
want to measure the radioactivity of the size fractions obtained,
particularly for
Cs-137, Am-241 and Pu isotopes. Distilled water would cause desorption of
some
of the adsorbed Cs. Unfortunately, Calgon does not seem to be very effective
as a dispersing agent in seawater. Any advice on other dispersing agents
would
be very welcome.
Thanks

Training Program on
COMPUTER SIMULATION OF CROP GROWTH AND MANAGEMENT RESPONSES
May 27 - June 7, 1996
Athens, Georgia
Presented by
The University of Georgia
College of Agricultural and Environmental Sciences
and
Georgia Center for Continuing Education
Site of Olympic Soccer, Volleyball, and
Rhythmic Gymnastics 1996
RATIONALE
Today more than ever, increased food production depends on
judicious use of resources. Many soil, climatic, plant, and
management factors affect the way a crop will respond to
irrigation, fertilizer and other management practices. Determining
appropriate crop management strategies under these uncertainties
has major economic and environmental implications. Computer
simulation models of the soil/crop/atmosphere system can make a
valuable contribution to both furthering our understanding of the
processes determining crop responses and predicting crop
performance in different areas. With the increasing availability
of personal computers, user-oriented simulation models will greatly
facilitate the task of optimizing crop and nutrient management and
deriving recommendations concerning crop management. They also can
be used to investigate environmental and sustainability issues of
agro-ecosystems. The University of Georgia, in collaboration with
the University of Florida, International Fertilizer Development
Center (IFDC), Michigan State University, University of Hawaii, and
the International Consortium for Agricultural Systems Applications
(ICASA), has been at the forefront in developing crop models and
decision support systems suitable for use and application in both
developed-and developing-country agriculture. The University of
Georgia is organizing this training program on Computer Simulation
of Crop Growth and Management Responses at the Georgia Center,
Athens, Georgia, from May 27-June 7, 1996.
PROGRAM OBJECTIVES
In this training workshop participants will learn how a
comprehensive simulation model of crop growth and development and
water and nutrient dynamics is constructed and how it can be
applied to real world problems. Specifically, the program will
focus on:
1. Operation of the new DSSAT v3 software.
2. Description of the CERES and CROPGRO computer
simulation models.
3. Data requirements and collection for systems
simulation.
4. Application of the simulation, models to cropping,
environmental, and sustainability problems.
5. Integration of the crop simulation models with data
base management and geographic information systems.
PROGRAM CONTENT
The program will describe the practical approaches to simulating
the effects of soil, climatic, management, and pest factors and
their interaction with the input needs of crops. The program will
demonstrate how the processes of crop growth and development, water
use, uptake of nutrients and response to irrigation, fertilizer,
and other management decisions can be simulated. The program will
make extensive use of "hands on" practical sessions on personal
computers that demonstrate the application of simulation models to
cropping systems in various regions of the world. Together with
these applications, the methods for assessing the economic risks
and environmental impacts associated with agricultural production
in real world problems will be discussed. Procedures for managing
soil, crop, and weather data will be described.
The program will make extensive use of the CERES (maize, wheat,
rice, sorghum, barley, and millet,), CROPGRO (peanut, soybean, dry
bean, and tomato), SUBSTOR (potato), and CROPSIM (cassava) models
for crop growth, development, and response to water and nutrients.
Techniques for simulation of synthetic weather sequences will be
described. Programs to create, run, and analyze both single season
simulations and crop rotation simulations will be explained. The
crop simulation models, data preparation, and application programs
have been integrated into the new Decision Support System for
Agrotechnology Transfer (DSSAT) v3 software package, Participants
will be provided with a complete copy of DSSAT v3.
ABOUT THE TRAINING WORKSHOP
The program will begin May 27 and end June 7, 1996. It will be
held at the Georgia Center, University of Georgia, Athens, Georgia,
USA. International participants should plan to arrive 2 days

One topic I would to see some discussion of is fluid flow and conductivity in
soils. I currently have a Site Technician Certification in VT.
This cert. allows me to classify soils and design on-site inground septic
disposal systems. The testing material in the state, however, mostly
concentrated on soil analysis and system design and not really on what
happens after discharge and/or the basis of the current adopted regulations.

Subject: Re: Discussion ??
Jeff:
What you have said is true for small, on-site leachfield system designs in
Vermont that are under the 1,000 gpd threshhold. Once a system is designed
that exceeds this threshhold, a limited hyrdogeologic study is required. As
the total leachate volume increases, the scope of the hydrogeologic study
increases correspondingly.
As you attain 6,500, 10,000, and 15,000 gpd threshholds, the state Indirect
Discharge Permit (IDR) process take precedence and the entire hydrogeologic
study becomes quite a complicated, regulatory-driven investigation as travel
and renovation time, along with downgradient impact (chemically and
biologically) to groundwater and surface waters at specific compliance points
are closely studied under pre-approved QA/QC programs.
The IDR process can take well over a year to complete for many sites
throughout the state; it is very expensive on both the engineering and
hydrogeologic end. This is why, as a Site Technician, you probably are not
frequently exposed to it; most developers can't afford to undertake these
types of investigations, therefore, they opt to go for individual, on-site
system design. Often it means sacrificing one, or several lots from their
project, but it can save many thousands of dollars in the design process, and
much time from the overall project approval span.
Please feel free to contact me direct with more specific question regarding
the IDR process.

Kent,
Thanks for your detailed reply to my discussion topic. The reason I submitted
the topic for discussion was more for a general conceptual analysis as to why
I would find mottling or GW in a test pit and how I could more easily
identify a good or bad site before the backhoe gets there.
Could you direct me to some good literature regarding these subjects.
I will keep you in mind for further questions :).
Thanks,

At Los Alamos National Laboratory, we are currently in the process of
remediating various sites
that have hazardous or mixed wastes. Budgets are very unpredictable but we
may be able to use
some summer help. Do you have HAZWOPER training and current OSHA medical
surveillance?

Hi list
My name is Patrick Vaughan. I am an adjunct faculty member (Geology) at San
Diego State University and a self employed engineering geologist working out
of Santa Cruz, CA. My interest in soils is primarily related to the
application of soil stratigraphic analysis and soil age dating to geologic
hazards, mostly active faulting.
My "burning" question is rather esoteric but I have not yet found any
information about this issue: Does aerosolic (coastal) sodium have any
influence on the rate of development and location of dithionite extractable
iron in sandy soils?
Thanks.

Dear Pat, and all,
This doesnt address your question exactly, but it may be
of relevance?
Maybe you want to look at Fe in soils for different reasons
to me. I primarily want to remove any potential interferents from
soils when I at the solid-state 13C CPMAS NMR of the organic matter
therein. In the publication below we showed that HF deashing was
far more efficacious in removing Fe minerals from soils than dithionite
treatment, and generally seems to have minimal impact on the actual
chemistry of the soil organic matter.
The removal of magnetic materials from surface soils.

Skjemstad J.O., Clarke P., Taylor J.A., Oades J.M., Newman R.H.,
Aust. J. Soil Res., 1994, 32, 1215 - 1229.
Perhaps your question has to do with the impact
of Na+ on the disperivness of clay minerals (high SAR values)
leaving behind very specific types of Iron containing
minerals as well as sand?
(A bit of gratuitous advertising now ;-) )
If you are interested in 13C CPMAS NMR
there are web pages and links (some still under construction)

Jeff:
An excellent reference on mottling, although perhaps hard to find, is Brian
T. Bunting's "The Geography of Soil", Aldine Publishing Company, Chicago,
Revised Edition, 1967. Check out pages 125-134.
As you know, mottling is indicative of a transitionally waterlogged horizon,
usually overlying a gleyed horizon. The mottling is caused by oxydation and
reprecipitation of ferric iron in the better aerated interstices of the soil
matrix. Bunting refers to some early work by Bloomfield (1951) where it was
found that the presence of high concentrations of leaf and grass debris in
the Ao horizon caused gleying in underlying horizons through degeneration and
reprecipitation of Fe. This was not found to be as prevalent in cases where
the Ao horizons were composed predominantly of raw humus or peat.
As far as getting a feel for the soils before you bring out the excavator;
that's a gut feeling that comes with experience. You should take the time to
start identifying wetland plant species, and to look at regional and
localized drainage patterns, both on your topo and in the field. Also, a
small-diameter hand auger is an excellent preliminary tool to carry out in
the field. I have one that, with handle extensions, can bore down to 16'
below-grade in favorable soils; many times I can get more than enough
information from a good series of hand borings to eliminate the need for a
backhoe completely.
I hope this is of help to you. Where in Vermont are you located? If you are
interested in a joint field excursion at some time, perhaps we could arrange
something.

Kent,
Thanks for the reference, I'll check my local library and see if they can get
it for me.
I live in Rutland and would be very interested in a joint excursion to
further my knowledge and "comfort level" regarding soils and the
identification thereof.
You see, it's not that I don't know what the hell I'm doing, it's just the
lack of time in and a minimal variety of soils that bothers me a little. I've
designed and/or reviewed probably a hundred disposal systems in the office,
but looked at maybe 50 pits altogether.
Please drop me a line if you have an opportunity for the joint venture in the
future. I'll buy lunch :)
Again, thanks for the offer.
Jeff
Happy Thankgiving to all, GO COWBOYS !!!!

Subject: Crop chloride content
Greetings, agmodelers and soils listers
Can anyone give me an idea of the chloride content of sweet corn, field corn,
or potato? I'm interested in the content of the standing crop at harvest
time, that is, I ultimately want to know the kg/ha of Cl taken up during the
season. References to published values, or your personal recollections, would
be helpful.
I have been advised this content varies a lot, and the plants tend to take all
they can get. The conditions I have are a sandy soil, where nearly all the Cl
is applied as KCl about a month before the crop is planted, so probably 6
weeks before emergence. My feeling is that these conditions would result in
rather low Cl uptake.
If you'd rather respond privately than to the list, my e-mail address is
below. Thanks....

I am not sure of your location, so I can't give you local contacts. In any
case, the best way to find local trainers is to contact any environmental

Phil,
Thanks for the info on removal of magnetics.
I think you picked up on the primary question I was trying to get at in the
second part of your response re: Na dispersion of clay minerals. Na
dispersiveness will affect clay accumulation in coastal soils and presumably
Fed location as well.
I have tried to use secondary Fed as a comparative tool to estimate soil age
in different California locales. While I can see increasing trends with age
at any particular site, rates of secondary Fed accumulation vary between the
sites, thereby limiting the comparative utility of Fed. Obviously, several
factors may influence the observed differences. I am trying to determine
what role Na and/or Na fluxes have in affecting the chemical paths that
control development of secondary Fed.
Thanks.

Hello!
Did any work with the SURFTEMP model for predicting soil temperature?
I was expecting to get some information from a presentation at the ASA
meetings (Comparison of measured and predicted soil temperature using
SURFTEMP) but the presentation didn't happen. Then, I was trying to find
something from the abstract but I couldn't find it.
I am collecting continuous soil temperature at different soil depths and I
thought it would be worth of trying the model to see how good it works for
my conditions.

Hi Marcus,
I assume that your core will be closed to the atmosphere during measurement.
The simple way to measure head space volume above the cores is to set up a
barometer so that you have a measurement of atmospheric pressure. Next,
in the head space above the core, attach a differential transducer that
measures somewhere around the 2 inch range. You can obtain these from
Honeywell Corporation which are called "Microswitch Transducers" and generally
cost about $22.00 each. The transducer may be attached to a datalogger;
we generally use the CR-10 by Campbell Scientific. Please contact me if I
can be of any assistance. Best regards.
