Introduction

Green biomass that contains high nutrients is good sources of nutrient for organic compost and increasing
the amount would correspondingly increase the nutrient quality of compost product.

Green compost materials are much higher in Nitrogen and are important element in amino acids
and proteins, serving as vital protein source for the compost microbes, helping to speed up the process of
decomposition. In this context, Nitrogen-rich leaves from fast growing legume tree Gliricidia sepium in the
live fence of different agroforestry models were utilized for this study. In fast composting, it also requires the
inclusion of a higher proportion of sappy green matter with higher nitrogen content (lower Carbon/Nitrogen
ratio) such as grass and other plant cuttings and poultry manure (Misra and Roy, 2004).

Materials and Methods

The study was conducted at Institute of Animal Nutrition, Kattupakkam, Kancheepuram District.
Nitrogen-rich leaves from fast growing legume tree Gliricidia sepium in the live fence of different agroforestry
models were utilized for this study. The objective of the study is to develop organic compost utilizing fresh /
fallen Gliricidia sepium tree leaves and evaluate its potential to support nutritive requirement of crops.

Kancheepuram district is dominated by agriculture based community where rice farming is the major
livelihood activities of the people. Abundant crop residue is a common after harvest in which some are burned
while others are just left to decompose naturally. Within the farming community, Gliricidia sepium, a legume
tree can be seen near residential houses as live fence and in boundary of the farmlots. The study followed the
Completely Randomized Design (CRD) in three replicates. The treatments (T) were Crop residue with fallen
leaves + Gliricidia green biomass at 3:3 ratio - Control (without inoculum)( T ) , Crop residue with fallen
1
leaves + Gliricidia green biomass at 3:3 ratio + EM culture( T ), Crop residue with fallen leaves + Gliricidia
2
green biomass at 3:3 ratio + TNAU Biomineralizer ( T ), Crop residue with fallen leaves + Gliricidia green
3
biomass at 3:3 ratio + Trichoderma viride)( T ).

The composting procedure used in this study was based on the recommended procedures given by
Cuevas, 1997 for composting and only varied with the addition of inoculam during composting.
