Organic amendments are very important in maintaining the soil productivity of sands. This research aimed at exploring the effects of variations affecting manure quality and nutrient availability that occur as a result of manure handling and storage. Secondly, the research evaluated the effects of these variations on the yield of peanut as well as soil properties of sands to which they are applied. The study was conducted by carrying out experiments on: (1) manure storage techniques; (2) manure storage using the pit method in three provinces; and (3) use of a combination of inorganic fertilisers and manure as a viable option for crop production for farmers. Our results indicated that pit storage produced better quality manure than the heap storage method traditionally used by farmers and could be a suitable option for extended storage of manure. In the field experiments, application of different organic treatments gave higher yields compared with application of inorganic fertiliser alone. The highest gross margins were found with an application rate of 10 tonnes manure/hectare produced by storage in a pit (manure:rice straw ratio of 1:0.5). Only few changes in soil properties were found after the peanut crop but incorporation of different types of organic amendments improved all soil properties more than application of inorganic fertiliser alone.
