    To determine if 6 years of zero tillage management has affected potential fertility and structure of the surface soil, in a 40-year crop rotation experiment in a Black chernozem at Indian Head. Further, to determine how any changes are influenced by fertilizer (N + P), legume green manure, legume hay crops, straw removal and cropping frequency.
