Final answer:
Crop rotation of corn and soy beans enriches the agricultural environment by balancing soil nutrients and ensuring sustainable crop production.
Step-by-step explanation:
Farmers often rotate corn (a cereal crop) and soy beans (a legume) because this practice has multiple benefits for the soil and the crops.
Planting a field with each crop in alternate seasons can enhance environmental quality and support the natural resource base necessary for sustainable agriculture.
Corn is primarily a source of carbohydrates, while soy beans contribute much-needed protein to diets and fix nitrogen in the soil, which helps fertilize subsequent corn crops.
This rotation can lead to an improved balance of essential nutrients in the soil and ensure a more sustainable crop production.
