Cover Crops are used to prevent soil erosion, improve soil structure, organic matter, suppress weeds and pests. They can also be used as forage for livestock. Cover crops cover the soil so that it is protected over the winter.
There are 4 types of cover crops:
- Grasses (Rye, Wheat, Barely, Oats) – Adds organic matter
- Legumes (Alfalfa, Clover, Peas) – Nitrogen fixer
- Brasicas (Radish, Turnips, Mustard) – Good for pest control
- Non-Legumes Broadleaves (Spinach, flax)
Here is a video from MIGardener that will help explain cover crops a bit further.
