Animal manure is of vital importance in maintaining soil fertility in semiarid west Africa due to the low level of use of inorganic fertilizer. Using data from Niger however, it is shown that insufficient animals are available to provide the manure needed to sustain crop yields on a long-term bas...

Despite its vital role in supporting crop production, a key question that has often been posed is whether sufficient amounts of manure are available to permit adequate food production and improvement of soil quality on a long-term basis. While this question can be addressed at a regional, nationa...
