Journal Article 1995

Autor: Williams, Timothy O. Powell, J.M. Fernández Rivera, S.

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...

Journal Article 1995

Autor: Williams, Timothy O. Powell, J.M. Fernández Rivera, S.

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...

Journal Article 1999

Autor: Williams, Timothy O.

Animal manure is one of the principal sources of nutrients for soil fertility maintenance and crop production in semi-arid west Africa. Farm-level decisions concerning the use of manure are governed by socioeconomic and institutional factors, as much as they are by agronomic ecological concerns. ...

Night corralling of livestock directly in crop fields during the dry season contributes to nutrient cycling for the benefit of crops. Rangeland grazing and corralling livestock on selected croplands result in a spatial transfer of organic matter and nutrients from rangelands to the corralling sit...
