Abstract

The decomposition of the leaf mulches ofLeucaena leecocephala, Gliricidia sepium andFlemingia macrophylla has been studied under field conditions. Mulch samples were analysed over a period of 70 days on carbon, nitrogen, phosphorus,potassium, calcium and magnesium left. Loss rates for the elements show similar patterns for the three mulches. Losses of mulch material are caused by decomposition as well as removal by soil-dwelling fauna (insects, arthropods, etc.) feeding on the mulch.

Based on the data decomposition-and nutrient release functions are developed for the three mulches. These functions are useful in alley-cropping system analysis and models.
