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. 

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.

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).

In September 1933, the Soil Erosion Service, which later became the Soil Conservation Service, was created in the United States Department of the Interior (Simms, 1970). The next month on October 10, 1933, the first soil erosion control project of the Soil Erosion Service was established in Coon Valley, Wisconsin (Geiger and Keller, 1970). 

The disastrous events of the Dust Bowl led to the Soil Erosion Service Act of 1935. On April 27 of that year, the United States Congress declared soil erosion a national menace in an act directing the USDA to establish a Soil Conservation Service (Wehrwein, 1938). Also in 1935, the Soil Erosion Service was transferred from the United States Department of the Interior to the USDA with Hugh Hammond Bennett as its head (Morgan, 1965). This was soon followed by the Soil Conservation and Domestic Allotment Act of 1936. The State Soil Conservation Districts model law of 1937 was designed to customize soil conservation measures to reflect more local needs, placing more public focus on agricultural production methods.

Pesticide labeling usually does not tell about these properties of the pesticide product. The Soil Conservation Service, Cooperative Extension Service, your trade association, or your pesticide dealer may have specific information about the characteristics of the pesticides you are using. 

Soil is also an important factor in the breakdown and movement of pesticides. Your local Soil Conservation Service can help determine the types of soil in your area and how they affect breakdown and movement. The three major soil characteristics that affect pesticides are texture, permeability, and organic matter. 

The Soil Conservation Service can provide valuable information on the geology of an area and on the potential for groundwater contamination on your property.

Culminating a long-term international effort, the Soil Survey staff of the Soil Conservation Service (U S. Department of Agriculture) developed a Comprehensive Soil Classification System (CSCS) for world soils (Soil Survey Staff 1975). The CSCS defines soil classes strictly in terms of soil morphology, rather than based on soil genesis. A brief explanation of the 10 soil orders in the CSCS is given in Table 7.4 (see also Bodek et al. 1988). Their temporal relationships are considered in Fig. 7.6. 

Procedures and techniques used with cement grouts in the United States were developed primarily by the large federal agencies concerned with dam construction The Corps of Engineers, The Bureau of Reclamation, and the Soil Conservation Service. Predictably, each of these organizations developed its methods unilaterally, resulting in major areas of difference in philosophy and execution. 

Rainfall at Lakeland, FL, for 1974 was 112 cm. Of this amount, 66 cm fell during a 72-h period. There were 24 periods of rain of 3-h duration each, averaging 2.72 cm of rain IS. The Soil Conservation Service (SCS) method [9] of estimating the quantity of runoff water was applied, resulting in 18 cm/year of runoff. Thus, the net amount of rainwater available to infiltrate the phosphogypsum was 94 cm in 1974. However, 1974 was an unusually dry year. Normal annual rainfall in the phosphate region is about 140 cm. Using the same runoff for a normal year results in a net available rainwater of 122 cm.
