Faecal excretion by ruminants and manure availability for crop production in semi-arid West Africa por Fernández Rivera, S., Williams, Timothy O., Hiernaux, Pierre H.Y., Powell, J.M.

“…A model is presented to predict the yearly faecal output by grazing ruminants under fluctuating feed supplies. Statistics on livestock population and cultivated areas are used to evaluate the effects of livestock to cropped area ratios and the spatial location of livestock at manuring time, on the potential amounts of manure available for crop production. …”
