Soil Fertility Replenishment in Africa: An Investment in Natural Resource Capital
Soil fertility depletion in smallholder farms is the fundamental biophysical root cause for declining per-capita food production in Africa, and soil fertility replenishment should be considered as anExpand
Agronomic Value of Unacidulated and Partially Acidulated Phosphate Rocks Indigenous to the Tropics
Publisher Summary This chapter evaluates the degree to which phosphate rocks (PR) and partially acidulated phosphate rocks (PAPR) are suitable for use in tropical agriculture. Considerable researchExpand
Role of manures and crop residue in alleviating soil fertility constraints to crop production: With special reference to the Sahelian and Sudanian zones of West Africa
In the West African semi-arid tropics (WASAT), continuous cultivation leads to drastically reduced levels of soil organic matter. Such reductions in the level of soil organic matter have resulted inExpand
Role of manures and crop residue in alleviating soil fertility constraints to crop production: With special reference to the Sahelian and Sudanian zones of West Africa
In the West African semi-arid tropics (WASAT), continuous cultivation leads to drastically reduced levels of soil organic matter. Such reductions in the level of soil organic matter have resulted inExpand
Alleviating soil fertility constraints to increased crop production in West Africa: The experience in the Sahel
Lack of moisture limits crop production in semi-arid west Africa but poor soil fertility is a more serious constraint in the long run. Work done by IFDC and ICRISAT showed that phosphorus is the mostExpand

Comparison of five soil testing methods to establish phosphorus sufficiency levels in soil fertilized with water-soluble and sparingly soluble-P sources
Field experiments were conducted in Niger with pearl millet (Pennisetum glaucum [L] R. Br.) in which the crop was fertilized with phosphate rock (PR) from two deposits from Niger (Tahoua and Parc W).Expand
Use of phosphate rocks in the tropics
The use of finely ground phosphate rocks (PRs) as directly applied P fertilizers in tropical farming systems is a cheaper alternative to acidulated, water-soluble P products. However, theExpand
Livestock and Sustainable Nutrient Cycling in Mixed Farming Systems of sub-Saharan Africa
Ever-increasing human population and urbanisation are intensifying the demand for agricultural commodities in sub-Saharan Africa (SSA). As a result, the traditional balance between people, theirExpand
