Crop rotation (change from continuous to different cropping systems and tillage practices (change from conventional to no-till) are two most important methods of soil carbon enhancement and can be expected to peak in long term.

Thanks Bahrani ji , you ere very right . beside these farmer can go for in-situ and ex-situ green manuring, organic manuring, cover cropping and residue retention of the crops in the field.

It is very important to to enhance organic C for sustainability of the soil and crop productivity through farm yard manure- use, crop residue incorporation, green manuring and inclusion of leguminous crops in crop rotation. By neglecting these, crop yields tend to decline.

Thanks sir for sharing of your views

Agroforestry practices have been proven as an effective means of increasing soil carbon sequestration.
