TAILIEUCHUNG - Effects of cattle and poultry manures on organic matter content and adsorption complex of a sandy soil under cassava cultivation (Manihot esculenta, Crantz)

Ducks do not require elaborate houses. The house should be well ventilated, dry and rat proof. The roof may be of shed type, gable or half round. It may have solid or wire floors. The wire floors are not popular with breeders. Under semi-intensive system the house should have easy access to outside run as the ducks prefer to be outdoors during the day time and even during winter or rains. Generally the proportion of night shelter to outside run is 1/4:3/4. The run should gently slope away from the houses to provide drainage. Normally a continuous water channel. | African Journal of Environmental Science and Technology Vol. 3 8 pp. 190-197 August 2009 Available online at http AJEST DOI ISSN 1991-637X 2009 Academic Journals Full Length Research Paper Effects of cattle and poultry manures on organic matter content and adsorption complex of a sandy soil under cassava cultivation Manihot esculenta Crantz S.

Accepted 14 July 2009 This study examined the A and B horizons of deep developed and moderately unsaturated sandy ferrallitic soils amended with cattle and poultry manures under cassava Manihot esculenta Crantz cultivation. Therefore a plot experiment was carried out by using a randomized complete blocks design in 4 replications and fields treatments which included unfertilized control and one dose 10 t ha of both manures. The study of the different fractions of animal manures showed that the poultry had the greatest content of C organic carbon N nitrogen P phosphorus K potassium Ca calcium and C N ratio p . However the value of Mg magnesium in the studied manures was not significantly different p . The manure treatment significantly increased the soil organic matter contents from to and respectively with poultry and cattle manures p . Organic fertilizer significantly increased the cation exchange capacity from to and me 100 g and the bases .
