Quality Assessment of Composts from different Organic sources

Abstract

Currently, environmental pollution is a global issue that is directly or indirectly related to human activities. Uses of chemical fertilizer also cause long-term environmental pollution. Concerning this, the composting technique for the management of organic waste is a good deal. This method or technique is better than chemical fertilizers as it is eco-friendly and environmentally friendly. The use of compost depends on its different quality parameters. The presented study shows the comparative analysis of three types of compost which were prepared by windrow type of composting. Composts were differentiated based on their organic matter source. Analysis of compost quality was done based on their macronutrient - Nitrogen, Phosphorus, and Potassium and the physical composition of compost. The result shows that all three types of composts match the quality standard of the Indian Fertilizer Control Order-1985. Compost from vegetable waste contains more nutrients as compared to others. All three were very less different in their nutrient composition. By comparing the composting time duration fruit waste is converted into compost earlier than others. This shows that vegetable waste gives high-quality compost that can be used as organic fertilizer. Fruits and farm waste are also useful but vegetable wastes give better quality compost concerning macronutrients.
