    Description

    FARMSIM consists of a crop-soil (FIELD), a livestock (LIVSIM) and a manure (HEAPSIM) module that are functionally integrated to allow capturing feedbacks between these identities at farm scale, as affected by farmers’ management decisions. FIELD simulates long-term changes in soil fertility (C, N, P and K), interactions between nutrients that determine crop production, and crop responses to management interventions such as mineral fertiliser and/or manure applications. Different fields within a farm represent combinations of crop types and sets of soil properties. Simulation of livestock productivity, growth and herd dynamics is done with LIVSIM, while nutrient cycling through manure is simulated with HEAPSIM.
