How does the use of cover crops impact the need for synthetic fertilizers and pesticides?

The use of cover crops can reduce the need for synthetic fertilizers and pesticides. Leguminous cover crops fix nitrogen, reducing the need for nitrogen fertilizers. Cover crops can also suppress weeds, reducing the need for herbicides. Additionally, they can improve soil health and promote beneficial insects, which can help to control pests and diseases, reducing the need for pesticides. Overall, cover crops promote a more sustainable and ecologically balanced farming system.
