Cover crops are plants grown between main crops to benefit the soil and environment. They help prevent erosion, improve soil quality, control weeds, and provide nutrients for future crops. Different types of cover crops, like legumes, grasses, and Brassicas, offer various benefits. Legumes help add nitrogen to the soil, grasses are good for erosion control and soil structure, and Brassicas help with nutrient recycling and weed control. Buckwheat is a fast-growing summer cover crop that is great for recycling nutrients and attracting bees. Choosing the right cover crop is important to avoid negative effects. Overall, cover crops can improve soil health, water quality, and wildlife habitats on farms.
