| description | Decomposition and N release pattern from the leaves of three shrubs species were studied under field conditions. Leaves of <i>Leucaena leucocephala</i> (Lam.), <i>Guazuma ulmifolia</i> (Lam.) and <i>Moringa oleifera</i> (Lam.) and two mixtures, <i>Leucaena</i> + <i>Moringa</i> and <i>Leucaena</i> + <i>Guazuma</i>, in a complete randomized block design, were studied during the dry and wet seasons. Litterbags were randomly distributed in each experimental block and placed on the soil surface, and residues were recovered after 2, 4, 8, and 16 weeks. Double exponential model decay was better fitted to describe the pattern of the decay of the release of various leaf constituents. Litter dry weight loss and N release were faster from <i>Moringa</i>, followed by the <i>Leucaena</i> + <i>Moringa</i> mixture, while the <i>Guazuma</i> leaf litter decomposed much slower. In the wet period, a rapid N release was observed for <i>Moringa</i> (60%) and <i>Leucaena</i> + <i>Moringa</i> (43%) in the first two weeks. In contrast, <i>Guazuma</i> and the <i>Leucaena</i> + <i>Guazuma</i> mixture released about 46% of N in 16 weeks. In the dry period, leaves released most of their N during the first 8 to 16 weeks. <i>Moringa</i> and <i>Leucaena</i> + <i>Moringa</i> ranked first, having lost 81 and 75% of its initial N, respectively. The ratios of condensed tannin and polyphenols to N were significantly correlated with the N released. It was concluded that the initial mass loss from the leaf litter was high and rapid in the rainy period in comparison to the dry period. The residue disappearance pattern of <i>Moringa</i>, <i>Leucaena</i> and <i>Leucaena</i> + <i>Moringa</i> followed an asymptotic model, with more than 80% of the original residue released during the 16-week study period. |
