The document discusses healthy soil and cover crops. It recommends getting a soil test from your local Extension Office or Midwestern Bio-Ag for a complete analysis. Cover crops add biomass and improve soil in various ways depending on the crop, such as suppressing weeds, fixing nitrogen, or breaking up clay. Buckwheat can be tilled in after blossoming to add biomass. A winter mix of rye, hairy vetch and crimson clover provides soil cover and nutrients into spring.
