Possible Residue Management Solutions

Collection

Residue incorporation (most difficult)

Burning

Complete burning (mostly practiced)

Partial burning

Residue Mulch

Impacts & Challenges

Conservation Agriculture & Residue management

Three Principles

• No/Minimum Tillage

• Soil Cover with residue

• Crop Rotation

Three Benefits

Enhanced Productivity

Richer Resources

Climate Adaptation

<<<<<<<<<< Choosing Directions >>>>>>>>>

•Un-sustainability can not be the option

•It need to be biophysically and socio-economically sustainable.

•Sustainability also demands confronting climate change

Way Forward• Turning Agriculture Waste into Wealth

• Forceful implementation or willful adoption

• Farmer and Environment Friendly Innovation, widespread with proper knowledge dissemination and effective trainings

• Innovative business cases for scaling and Win Win for all

• Avoid Policy Mismatch

• Super SMS should be mandatory, Combine custom operator should also have two Happy Seeders per combine (1200+1400)

• Breakeven

• Farmer should be rewarded for not burning

• A Sacred service to save environment, water, soil health and timely seeding with more net returns
