The most important factors limiting agricultural
production in Iringa District is deterioration of soil fertility, high prices of in
organic fertilisers and accessibility to the villages. Recently, there has been an increased interest in the use of organic materials as a locally and cheap available source of nutrients for crop production. This paper describes the findings obtained from a survey which was conducted in Iringa District about the extent of the current use of organic manure. It outlines different nutrient values of different manures and benefit of there use. It also discusses the constraints which restrict their widespread use and suggests strategies for encouraging their more effective use in the future. Le Mare, P.
