 ;USDA–CSRS Water Quality Activities Priority Components Research Program:

Twenty-three water quality research grants were competitively selected for awards in 1989 and 46 in 1990 under the Cooperative State Research Service (CSRS) Water Quality Special Research Grants Program, with another 44 to be awarded by CSRS in 1991. These projects are part of CSRS’s major program component under the President’s Water Quality Initiative.

The following are selected examples of progress being made on some of these research grants:
 * Progress is being made by South Carolina scientists in the use of an electromagnetic (EM) technique to map underground concentrations of certain chemicals leaking from farm lagoons.
 * Research in North Carolina shows progress in mapping the potentials of soils for poultry litter application as based on soil characteristics.
 * Promising new methods for safe on-farm disposal of pesticide wastes are being developed by Arkansas scientists.
 * Greater understanding is being obtained by scientists on the degradation, persistence, and movement of pesticides, such as atrazine and metolachlor and other chemicals at several locations. Early results in Montana studies show dicamba movement through soils was reduced as more time was allowed between chemical application and irrigation.
 * Missouri research shows that movement of pesticides through soil cracks and large pores was decreased if irrigation was delayed after application of chemicals.
 * Less preferential flow of water and solute occurred in soils in applications of chemicals were made to wet soils after irrigation rather than to dry soils before irrigation in Arizona research.
 * Detoxification of contaminated soils and water by inoculation with microbes or by application of enzymes holds promise of being more cost-effective than presently-used physical–chemical treatments, according to research in Pennsylvania.
 * West Virginia studies of the bacterial quality of water passing through activated charcoal filters, show promise for cleaning up drinking water in home water systems.
 * In Washington and Oregon, economic costs are being determined of farm management changes that could result from policies to abate possible nitrate build-up in ground water. Records of chemical use and field operations are being combined with soil and other factors to improve prediction models of chemical contamination of ground water.
 * Improved models are the result of research in Oklahoma and Florida that can better match soils and crop management strategies for use by Extension, Soil Conservation Service, and farm managers.
 * In New York research, improved simulation models and geographic information system (GIS) maps are being developed, improved, and tested to predict chances of pesticide movement to ground water.

A Farm Demonstration Tour of one of the USDA Demonstration Projects in Maryland, will be held Friday, July 26th. The focus of the program is to show Monocacy target area farmers how Best Management Practices (BMP’sBMPs [sic]) are being implemented on neighboring farms. The idea is to let farmers talk to farmers about the pros and cons of various practices, and discover what options might work well on their own operations. ES, SCS, and ASCS are cosponsors of this project near Frederick, MD. For information about the tour call the Monocacy Project office at (301) 899-0133.
