In the Sahelian rangelands biomass production is constrained by soil moisture in the drier (100-250 mm) parts and by soil nutrients in the wetter parts. Similarly, for a given Sahelian range, nutrient deficiency would be more prominent in good than in poor rainfall years. To test this hypothesis,...

Crop livestock production systems in Africa are constrained by wide fluctuations in the quality and quantity of feed resources during the year and by the low availability of nutrients, especially nitrogen and phosphorus, in most soils, which threatens the sustainability of primary production. In ...
