However, reliance on locally available organic nutrient sources for both crop and livestock production is rapidly becoming unsustainable. A series of feeding and agronomic trials have been conducted to address the role of livestock in sustainable nutrient cycling. This paper reports results of a greenhouse study that evaluated the effects of applying crop residue and browse leaves, or feces derived from these feeds, at equal organic-N application rates (150 kg ha Springer 1999 Article PeerReviewed application/pdf en http://oar.icrisat.org/5110/1/NutrCycAgro54%283%29215-226.pdf Powell, J M and Ikpe, F N and Somda, Z C (1999) Crop yield and the fate of nitrogen and phosphorus following application of plant material and feces to soil.
