Evaluation of the effect of Organic Waste on Nutrient Quality of Compost

Abstract

The technique of composting is the degradation of organic matter and production of valuable nutrient rich compost that can improve soil fertility. The use of appropriate type of organic waste for composting can give better result when compost is applied on soil. It will improve in proper recycling of organic waste into a value added soil amendment. So, the presented study is to evaluate the nutrient contents and physiochemical parameters of compost prepared from different types of organic waste. The study was done by taking 4 types of wastes (A=fruits waste, B =vegetable waste, C=farm waste, D= cooked leftover food). The analysis of compost showed that nutrient content and physiochemical parameters considerably affected by the type of organic waste used for composting. Waste from the cooked leftover food contains more nutrient content as compare to other waste (N=.42%, P=.19%, K=.36%). Organic matter was also higher in cooked food waste (8.18%). The C/N ratio for fruits and vegetable waste was same, 11:1 and highest for cooked food waste, 13:1. The result of experiment shows that nutrient contents and physiochemical parameters of compost prepared from cooked leftover food was better than the other wastes that were used for study. All the compost prepared matched the standards of Indian Fertilizer Control Order. So these compost are suitable for the use on soil.
