I followed the lead by Ron on the ATV discer from lowes for $158. In the directions it states that the discs are used to break up previously plowed soil. For remote food plot use, can I just remove the leaf litter/dead grasses and disk to break the soil, or do I have to plow first? I am planting rye/oats/wheat/brassicas and annual clovers (no-plow seeds) in some fertile soil.
