What is wrong with tilling?

The downside of tilling is that it destroys the natural soil structure, which makes soil more prone to compaction. By exposing a greater surface area to air and sunlight, tilling reduces soil’s moisture-retaining ability and causes a hard crust to form on the soil surface.
