Journal Article 1998

Autor: Shapiro, Barry I. Sanders, J.H.

In semiarid West Africa, inorganic fertilizer use and sustainability objectives are complementary. With increasing population pressure and low levels of purchased inputs, crop yields in many regions are declining. Moderate use of inorganic fertilizer is required for increasing yields in a sustain...

Two critical factors that explain low crop productivity in the Sahelian agro-ecozone are inadequate moisture and poor soils, particularly phosphorus (P) deficiency. The purpose of this long-term study was to explore the use of both local phosphate rock (PR) and inorganic P on yields and risk of...

Autor: Shapiro, Barry I. Sanders, J.H.

An important debate is currently under way among researchers and policy makers about the relative merits of using organic versus inorganic fertilisers to improve soil fertility in semi-arid areas of sub-Saharan Africa. Environmentalists argue that use of inorganic fertiliser contributes to natura...
