Management and utilization of animal manure as a resource for crop production under two major grazing systems in Tanzania
Kimbi, G.G|Semoka, J.M|Lyimo-Macha, J.G / 2001

A study was carried out to establish and analyse factors limiting use of animal manure for crop production and evaluate manure management practices under two major animal grazing systems in Morogoro, Dodoma, and Kilimanjaro regions in Tanzania. The results of the study indicated that major variations revolved around the two grazing systems studies, use of manure for crop production and extent of manure management were highest in areas of high population density and extensive grazing system. Major constraints to manure use in extensive grazing system included inadequate knowledge/skills, inferior transport facilities and long distance to the farms. Low volume of manure production was found to be major problem in intensive grazing system. In this system there was evidence of use of other organic fertilizers such as crop residues The paper, therefore, concludes that efforts be directed towards sensitising and training program aimed at increasing extent of animal manure use, as well as manure management in areas of low population density where extensive grazing system is usually practiced. In areas of high population density and intensive anima keeping system, focus should be on manure management because of animal manure for crop production is already common. Strategies to address manure use constraints should thereof ore take into account differences in grazing systems in planning soil fertility improvement programme
