Chandra to roll the crop down we should get a roller something similar to whats shown by sri which can cut the stem of the plant which inturn will will make the plant to lie down on the ground and eventually dry(i have seen a lot of farmers using weedicide sprayer attached to these wheels which cut the cover crop and sprays herbicide on them at the same time) i dont think rolling down the cover crop wont be a major issue for cover crops like RYE, long and thin stem plants. Major issue i see is building an equipment or lets say a drill which can cut through the cover crop and plant seed directly on the ground because eventually only those seeds germinate which are in contact with the soil I have seen zero tillage seed drills in ludhiana but none of them actually cuts the left over thats on the ground instead it drags the material with itself and then you need an additional labour to manually remove it from the tynes because it starts effecting your seed rates. Hope you understood what i meant. Sorry for being so haphazard, i shall try and be more systematic next time.
Chandra i can see alot of added advantage with no till farming plus using a cover crop once a year which can return all the nutrients to the soil and eventually lower our fertilizer rate for the next crop.
We should workout a good mixture of cover crops that we can use in our climate conditions because as i read somewhere, the more diverse the cover crop the better it is.
