The model simulates the effect of surface mulch on runoff, soil
loss and crop yield. Crop growth simulation is based on SUCROS* [Notice: see
MAIZE. The model is validated for maize and the mulch type of Cassia
siamea prunings, in Madakos, Kenya, but if the necessary crop physiological
properties and mulch decomposition rate are known, other species may be
