In the Sub-Saharan Africa,
soil-fertility depletion in smallholder farms is the fundamental
biophysical root cause for declining per capita food production. In
the soils of this region, Phosphorus deficiency is widely considered
the main biophysical constraint to food production in large farmland
areas. Therefore there is a need to adopt measures in order to build
up soil P capital especially among smallholder farmers who are
economically poor. It has been reported that use of inorganic
fertilizers is a fast and immediate way to avail P mostly for plant
uptake and boost crop yields. Meanwhile organic fertilizers either
alone or combined with inorganic fertilizer have also shown its
importance in rising up soil available P and other adjacent
contribution to promote nutrient uptake and lastly increase crops
yield. This review paper explores the different alternatives which
may be adopted by the smallholder farmers in SSA in order to build
up soil available P and increase the yields of their crop.
