Some farmers use a plow or disc to turn over and loosen the soil after harvest - a process called tillage. There are 3 types of soil tillage including conventional, conservation and no-till. Conventional tillage can leave the soil exposed to rain and wind, which can sometimes lead to soil erosion. Conservation planting allows the crop residue to break down, which adds organic matter while protecting the soil from erosion. No-till works in the same way as conservation tillage, but there is less disruption of soil since the planter does not go as deep to plant the seeds, and no crop residue is turned over.
