Abstract/Contents:The effects of different application rates of sewage sludge and sludge compost (0, 40, 80, 120, and 240 metric tons/ha) on soil physical and chemical properties were studied at two pH levels. Sludge application rates exceeding 120 metric tons/ha were difficult to apply and produced a cloddy seedbed, while the same rate of compost was easily applied and produced a friable seedbed. Sludge and compost increased the water content and the water retention of a silt loam soil. Both the sludge and compost increased the salinity and chloride levels of the soil to a level which may affect salt-sensitive plants. The soil's cation exchange capacity increased as much as threefold as a result of the addition of sludge and compost. Nitrate-nitrogen levels were highest at the 15-20 cm soil depth but decreased sharply below this level. Available phosphorus was high during the 2-year study and appeared to be in excess of that needed for good crop growth.
