Talked to my professor about tilling and green manure

14 years ago

We were talking about mycorrhiza and then she talked about ploughing in green manure - cover crops. I asked her about no till practices, and, wouldn't tilling destroy the myco networks?

She said although that can happen, tilling in green manure helps it decompose faster, and that the destruction to the fungal works is outweighed by the benefit of green manure.

She said no till practices are relatively new, and are mainly used for erosion control.

So I wonder, if there aren't any erosion concerns where someone is, would it be better to till in green manure, say once a year, as opposed to not tilling it in at all? According to my professor, yes. What do you think?
