5 Benefits of Crop Rotation for Sustainable Agriculture | Crop Management

b
To use up all of the nutrients in the soil so that our crops are more nutritious.
c
To keep the soil more healthy, by using crops that demand different soil nutrients, while others even put nutrients back in the soil.
d
To determine which crops will succeed the best, so that next year the farmer can plant just that one crop year round.
