Abstract
Land applications of sewage sludges on agricultural soils are frequently used to recycle nutrients such as N through crop production. The rates of application have to be adjusted to the crop needs to avoid excess concentrations of NO- 3 in soils likely to be leached. The organic matter mineralization in soils or of organic amendments are often characterized via laboratory incubations, and first order kinetics used to describe C and N mineralization, allowing the determination of potentially mineralisable C and N (Lindeman and Cardenas, 1984; Stanford and Smith, 1972). Sewage sludge degradation in soils and the amount of N available for crop use vary with the pedoclimatic conditions including soil characteristics (texture, structure, pH, organic matter, microbial activity, etc.), temperature, soil water content and aeration.
