Advances in integrated soil fertility management in sub-Saharan Africa: challenges and opportunities. | 2007

Nutrient balances for different farm types in Southern Mali

S. Kanté; E.M.A. Smaling; H. van Keulen

Soil nutrient mining is one of the main causes of the current stagnation, or even decline in crop yields in Southern Mali. Limited information is available on the impact on soil fertility of different management packages as implemented at different farm types. The aim of the current study was to analyse nutrient flows in agricultural systems in Southern Mali for different farm types in two villages, varying in pressure on the soil resource. In each of the villages, 20 farms were selected and classified in three classes on the basis of differential nutrient management. Partial nutrient balances (imports in fertilizers minus exports in grain and straw) and complete nutrient balances (including difficult-to-quantify flows) were established.
