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. ...

Livestock manure is an important source of nutrients for crop production in semi-arid West Africa. An assessment of the potential of manure to sustain crop production calls for an estimation of the amounts of manure that could be produced and captured and the feed resources required to maintain l...

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

Animal manure is of vital importance to soil-fertility maintenance in semi-arid West Africa due to its intrinsic value as a soil amendment and because of the low level of inorganic fertiliser use. This paper provides a regional overview of manure utilisation for food crop production. Results of e...
