@ThommesM: I am also reading up about tilling less and I love your leaves under the oak tree mulch.
Has anyone tried undersowing with the green manures? I have been reading Elliot Coleman's books and bought some seed to undersow corn, root crops, tomatoes, beans, etc. In some experimental cases they are using only the green manures as the growing mulch and when the overwintered cover crops die back it stays as mulch ...planting directly in the cover crop. So interesting!
