Note sur la pathologie du bétail en Grande Comore (République Fédérale Islamique des Comores)
Abstract
Note on the pathology of livestock in Grande Comore (Islamic Federal Republic of Comores). This study on maize growing in pots shows that (i) in combination with other inputs (farmyard manure and lime), the most soluble phosphorus sources (triple and simple superphosphate) can be replaced by partially acidulated rock phosphate (50 %) obtained by mixing simple superphosphate and rock phosphate both originating from the rock phosphate deposits in Matongo (Burundi), (ii) the exchangeable Al can be reduced by both the addition of farmyard manure and lime, but the action of the different phosphorus 'source leave the most Bray-1 extractable phosphorus in the soil, the largest quantifies correspond to the highest doses of farmyard manure.
