Abstract

African soils are commonly short of phosphorus (P). Additions of fertilizer P can increase yields on most soils which have not previously received additional P. Agroforestry and management of mycorrhizas have the potential to improve the P nutrition of crops in tropical Africa but they cannot, however, replace P removed in additional crop yields. This review deals with two main problems: Assessment of fertilizer P requirements (Sections 1-4); Residual effects of fertilizer P (Sections 5-8).
