What are 3 types of cover crops?
It’s important to note that there are four classes of cover crops: grasses (such as ryegrass or barley), legumes (such as alfalfa or clover), brassicas (such as radishes or turnips) and non-legume broadleaves (such as spinach or flax).
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.
