An extensive pesticide properties database was compiled, which includes six physical properties, ie, solubiUty, half-life, soil sorption, vapor pressure, acid pR and base pR for about 240 compounds (4). Because not all of the properties have been measured for all pesticides, some values had to be estimated. By early 1995, the Agricultural Research Service (ARS) had developed a computerized pesticide property database containing 17 physical properties for 330 pesticide compounds. The primary user of these data has been the USDA s Natural Resources Conservation Service (formerly the Soil Conservation Service) for leaching models to advise farmers on any combination of soil and pesticide properties that could potentially lead to substantial groundwater contamination.

A successful modem hazardous industrial waste treatment program for a particular industry will include not only traditional water pollution control but also air pollution control, noise control, soil conservation, site remediation, radiation protection, groundwater protection, hazardous waste management, solid waste disposal, and combined industrial-municipal waste treatment and management. In fact, it should be a holistic environmental control program. Another intention of this handbook series is to provide technical and economical information on the development of the most feasible total environmental control program that can benefit both industry and local municipalities. Frequently, the most economically feasible methodology is a combined industrial-municipal waste treatment.

Information on surface soils is available from a number of sources, including surface soil maps compiled by the U.S. Geological Survey and the geological surveys of various states. At the present time, the coverage of such maps is not complete, nor has any systematic data on air permeability of soils been compiled. However reports issued by the Soil Conservation Service (SCS) of the U.S. Department of Agriculture contain information on most soils on a county-by-county basis. While no direct air permeability information is contained in these reports, the data and descriptive material contained there may be useful in estimating air permeabilities.

Soil is one of the most important natural resources because it is the central basis for all agricultural activity. Soil conservation is most important as it maintains the productive capacity of this resource. Environmental effects related to different uses of soil are equally important.

Conservation agroecosystems developed in the Great Plains of the U.S. to control soil erosion are characterized by the presence of varying quantities of plant residues on the soil surface. This residue mulch protects the soil from the erosive forces of wind and water, resulting in improved stream water quality and soil conservation. Conservation tillage systems also help maintain soil productivity and reduce energy requirements of crop production (15). However, crop yield reduction has been observed with conservation wheat production in some areas of the U.S. (16-18) and with rice culture in the Far East (, 20). 

Poor soil-conservation practices in the early 1900s contributed to the loss of much topsoil to wind storms thick with dust.

Great Plains created what was described as a black blizzard (Hurt, 1977, 1981). The disastrous events of the Dust Bowl led to the US Soil Erosion Service Act of 1935, which declared soil erosion a national menace and directed the US Department of Agriculture to establish the Soil Conservation Service (Wehrwein, 1938).
