Importance of Livestock Manure in Crop Production in Tanzania

Soil nitrogen depletion is considered one of the important constraints to improving the productivity of crop production in sub-Sahara Africa. It has been found that farmers cannot afford to apply recommended levels of mineral fertiliser to cropland, leading to nutrient mining. With the increasing importance of livestock in the livelihoods of poor farmers, livestock manure or leguminous forages can offer a potential solution to soil fertility loss in mixed farming-systems. Studies have found positive effects of manure application on crop yield, but the effects depend on the management practices when handling the manure. The objective of this study is to investigate how small-scale farmers in mixed systems in Tanzania manage soil fertility and manure and how their use of manure affects crop productivity. Data for this study is derived from a sample of 994 livestock keepers interviewed in 2017.
