We used to basically throw and mow cover crops from an airplane and just let crop fodder lay on it after harvest. After several dry falls that method left skippy stands and undesirable waste of seed. Now we spread after crop is off and cover with turbo tills for ensuring seed to soil contact. And the summer stuff I just couldn’t stand to see all the pigweeds and nightshade go to seed. That’ll present trouble on down the road. I do live by no till. Tillage has its place as said before to fix drainage issues. There’s extremes to everything I’ll keep no tilling my plots. Best of both worlds.
