CROP RESIDUE MANAGEMENT

DEFINITION • Crop residue management means maintaining cover on 60% of the soil surface at planting to protect water quality.

• It also provides seasonal soil protection from wind and rain erosion and adds organic matter to the soil.

• It conserves soil moisture, improves infiltration, aeration and tilth.

INTRODUCTION The crop residue is the material left after the

harvesting of crop and byproduct of agriculture based industry.

PRESENT STATUS OF CROP RESIDUE MANAGEMENT

Farmers have been burning large quantities of crop residues, particularly in areas with high yield potential.

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.

Crop residue

Field residuee.g. stalks, leaves, and stems etc

Processed residue e.g. seed, bagasse, and roots etc

Field residue:-

Good management of field residue can increase efficiency of irrigation and control of erosion.

Field residue are materials left in an agricultural field or orchard after the crop has been harvested.These residue includes stalks and stubbles (stems), leaves and seed pods.

Process residues

They can be used as animal fodder and manufacture of organic manure .

Process residue are those materials left after the processing of the crop into a usable resource.

These residue include husks, seeds, bagasse and roots

Potential uses of crop residues

Biomass energy production

Livestock feed Compost

Biogas generation

Mushroom Culture

Raw material for industry

EFFICIENCY OF NUTRIENT UPTAKEThe efficiency of nutrient uptake by crops from fertilizers or residue release is generally thought to be similar.

It has a great economic value, mineralogist nutrient uptake .

Due the crop residue management the yield and quality will be good.

It also improves soil quality and crop productivity.
