Abstract

This study was carried out to evaluate the effect of three fast growing agroforestry tree species; Acacia crassicapa, Gliricidia sepium and Leucanea leucocephala, litters on the organic matter content of the soil. The soil samples were collected from the plot supporting the ten years old tree species with the use of a soil hugger at three depths; 0-10cm, 10-20cm and 20-30cm and were analysed for percentage organic matter content. The data collected were subjected to analysis of variance (ANOVA) at 5% level of significant. The results indicate that organic matter was highest at 0-10cm under leucanea leucocephala followed by Gliricidia sepium, and least in Acacia crasicarpa. Percentage organic matter was highest at depth 10-20cm in Acacia crassipa followed by Leucanea leucocephala and least in Gliricidia sepium. At depth 20- 30cm, percentage organic matters was also found highest in Acacia crassicapa followed by Leuceana leucocephala and Least in Gliricidia sepium. The result shows significant difference in percentage organic matter under the different tree species and at different level.
