"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 Julian Clifton <------------------------------>

Date: Thu, 9 Nov 1995 17:45:23 -0500 From: "Dr. Gerrit Hoogenboom" .<.gerrit@bae.griffin.peachnet.edu.>. Subject: Crop Modeling Workshop --=====================_815967895==_ Content-Type: text/plain; charset="us-ascii" --=====================_815967895==_ Content-Type: text/plain; charset="us-ascii" 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.

Date: Tue, 14 Nov 1995 14:01:38 -0500 From: KSKgeos@aol.com 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 S.

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?

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.

Date: Fri, 17 Nov 1995 14:45:30 -0500 From: KSKgeos@aol.com Subject: Re: Discussion ?? 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.

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.

Date: Tue Nov 21 09:27:56 CST 1995 From: wstites@fsmail.uwsp.edu 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....

Date: Tue, 21 Nov 1995 13:26:22 -0500 From: Soilage@aol.com Subject: Re: Fe in soils 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. Patrick Vaughan <------------------------------>

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.

Thank you in advance for your responses, Marcus Graduate Student Soil Physics Group Department of Environmental Science, Policy and Management 108 Hilgard Hall University of California at Berkeley Berkeley, CA 94720 510-643-0956 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. James A.
