Working Paper 1992

Autor: Haque, I. Aduayi, E.A. Sibanda, S.

Examines the present status of research on copper (Cu) in the soil, plant and ruminant animal system in sub-Saharan Africa with emphasis on forage crops. The soil content of total and available Cu and the distribution of Cu in the soil profile are demonstrated. The biochemical role of Cu in the p...

Conference Paper 1992

Autor: Haque, I.

Crop livestock production systems in Africa are constrained by wide fluctuations in the quality and quantity of feed resources during the year and by the low availability of nutrients, especially nitrogen and phosphorus, in most soils, which threatens the sustainability of primary production. In ...

In most small-scale farms in sub-Saharan Africa, net negative balances of nutrients result when nutrients are removed from the farm by harvested crops, because farmers cannot afford inorganic fertilizers. A key resource that could be useful in reversing this trends is manure from livestock. The N...
