Conference Paper 1996

Autor: Powell, J.M. Fernández Rivera, S. Hiernaux, Pierre H.Y. Turner, M.

The sustainability of nutrient transfers in integrated rangeland/cropland systems of the Sahel was examined in relation to the impact of livestock. Rangeland nutrient balances are considered in equilibrium whereas croplands lack the internal capacity to replenish nutrient off takes in grain and c...

The influence of forage type, feed allowance and watering time on faeces and urine excretion by cattle, sheep and goats was studied. Higher amounts of nitrogen (N) were excreted during the day than during the night. The occurrence of defaecation and urination was highest at the time of getting up...

Conference Paper 1995

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...
