Manure management

  1. 1. Manure management 4. Good manure management • Avoiding losses of manure mass (liquids and solids) from the boma, the storage system and the field. • Limiting exposure of excreta to the air through: (1) rapid and complete removal of faeces and urine from the floor of the building to the storage facilities; (2) covering solids with a plastic sheet; and (3) immediate incorporation into the soil of the manure after field application. • Store manure solids tightly compacted on a heap or in a pit, and covered with plastic sheet to restrict the impact of rain and wind. • Mix the manure with materials with a high C/N ratio may reduce N losses during storage. • Manure should be applied to the field shortly before or during active crop growth and immediately incorporated into the soil to avoid N losses.

Why manure? • Animal manures contain important plant nutrients such as nitrogen, phosphorus, potassium and other trace elements. • Animal manure addition to soil increases the biological activity of the soil. Increased soil biological activity results in an increased nutrient availability. • Animal manure provides organic matter for the soil, which is very important for soil fertility. As manure decomposes, crop nutrients are supplied to the plant gradually over time. • Animal manures provide nutrients for immediate crop growth and also for future yields. • Correct use of animal manure subsidises the use of inorganic fertiliser and mitigates climate change.

Collect as frequent as possible, as fresh as possible and put in the soil as fast as possible II. Always cover your manure heaps/pits III. Use manure in fodder as well as in cash crops I II III Light Jesse Owino, International Livestock Research Institute Jesse Owino Mazingira Centre, International Livestock Research Institute, P.O.
