| Description |
An FAO study reveals that the loss of soil fertility in some African countries is so rapid that food production targets will not be met by the end of the century unless land management techniques improve drastically. FAO scientists studied soil fertility in 38 sub-Saharan countries in order to establish the amount and rate of loss of the primary plant nutrients, nitrogen, phosphate and potash, set against the inputs of mineral fertilizers, manure, rain and dust deposits, biological nitrogen fixation, and sedimentation. The result was that these countries suffered net losses each year which were described as 'awesome' - up to 60kg of nitrogen per hectare, 25kg phosphate / ha and 60kg potash/ha. The situation will be redeemable only if improved land management uses chemical fertilizers more efficiently, leaves crop residues, and minimizes leaching and erosion.
