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.
NUANCES-FARMSIM (FArm-scale Resource Management SIMulator) is an integrated crop – livestock model developed to analyse African smallholder farm systems.
