Abstract:

Decomposition of plant and animal debris described by a single pool Plant debris input needs to be calculated only in the plough layer because of the one-layer nature of the model. Plant debris input was estimated based on the yield of the specific arable crop according to the method of F.I. Levin (1977) Agrochemistry, no.8, p.36 (in Russian) Decomposition of soil organic matter described by a single pool obtained by fitting
