Journal Article 1998

Autor: Powell, J.M. Ikpe, F.N. Somda, Z.C. Fernández Rivera, S.

Most farming systems in semi-arid West Africa rely on organic matter recycling for maintaining soil fertility. The cycling of biomass through ruminant livestock into dung (faeces) and urine that fertilize the soil has long been an important factor in the nutrient cycling processes of these integr...

Journal Article 1997

Autor: Somda, Z.C. Powell, J.M. Bationo, B. André

The changes in soil pH and mineral N concentrations of cattle and sheep urine patches were compared to those occurring in fertilizer urea placement zones in a study in Niger. Urine and fertilizer solutions each containing 400 mg N (800 kg N/ha) were spread onto individual plots covering a surface...

Autor: Somda, Z.C. Powell, J.M. Fernández Rivera, S. Reed, J.D.

Mixed farming systems in semi-arid West Africa rely on recycling organically bound nutrients to maintain soil productivity. The passage of plant biomass through ruminant livestock plays a major role in the nutrient cycles of this region. The feeding value of crop residues and browses and their im...
