Crop residue As a component of INM

Crop residue as a component of INM The crop residue is the material left after the harvesting of crop and byproduct of agriculture based industry. Introduction

Present status of crop residue management Crop residue as a component of INM As the crop residues may interfere with tillage and seeding operations for the next crop, many farmers prefer to burn the residues left in the field that lead to air pollution and wastage of nutrients. Farmers have been burning large quantities of crop residues, particularly in areas with high yield potential.

Process residues Crop residue as a component of INM They can be used as animal fodder and manufacture of organic manure viz. vermicompost.

Potential uses of crop residues Crop residue as a component of INM Biomass energy production Livestock feed Compost Mushroom Culture Production of base material for Oyster mushroom production

Crop residue as a component of INM Potential uses of crop residues Bedding material for animals Biogas generation Raw material for industry Fuel Production of vermicompost As packing material and thatching of houses, compost pit etc.

Nutrient composition of vermicompost and garden compost Nutrient element Vermicompost (%) Garden compost (%) Organic carbon 9.8– Nitrogen 0.51– Phosphorus 0.19– Potassium 0.15– Calcium 1.18– Magnesium 0.093– Sodium 0.058–0.158 <0.01 Zinc – Copper – Iron – Manganese – Crop residue as a component of INM Source: ICRISAT, 2004

As a result crop residue is being burned and used mainly for livestock feed. However crop residue can be used as an energy source, compost, ethanol production, fiber production and other synthetic compound formation. Future prospects Crop residue as a component of INM The value of crop residue for protecting fields and maintaining soil fertility and productivity for future food and fiber production is often misunderstood.

Crop residue is that material left after harvesting the crop and processing the crop into usable resources. It is a good source of nutrients which is utilized by transforming the crop residue into compost and other usable products. Crop residue as a component of INM Let Us Sum Up:
