A Study of Generation and Regulation of Crop Residue: Bioenergy

Abstract

Background: Agricultural residues are a significant part of the waste generated in India. It is challenging for farmers to manage surplus crop residue sustainably because of large production and limited options. Ultimately, most farmers burn crop residue without giving it a second thought. Besides affecting the environment, burning crop residues also reduces soil fertility, soil nutrient content and soil organic humus levels by releasing greenhouse gases. Methods: This study was conducted to identify surplus crop residues available and their current uses. Vidarbha region in Maharashtra was selected for the study and cotton, tur and soybean crops were selected since these are the most commonly grown crops there. A man-to-man survey was conducted to determine the type and amount of crop residue available and how it is currently being used. Three farmlands in the Vidarbha region of Maharashtra were selected for the study. Four different varieties of cotton, tur and soybean were grown on three farms. The yield and crop residue generated were measured per unit area. Analysis of crop residue availability was conducted using statistical methods. Result: Based on the study, it can be concluded that biomass waste is abundantly available and there is potential to generate bioenergy by utilizing agricultural waste effectively. Furthermore, the regression study shows that crop output is a major predictor of crop residue generated.
