When a farmer plants a field with different crops from year to year, this is called Crop Rotation. How is Crop Rotation keeping our farmland sustainable for future use? a To cross pollinate and make new hybrid crops 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.

Answer 1

c To keep the soil more healthy, by using crops that demand different soil nutrients, while others even put nutrients back in the soil.

Crop rotation helps prevent soil depletion and promotes soil health by diversifying the types of crops grown in a field. Different crops have different nutrient requirements, and rotating crops can prevent the depletion of specific nutrients in the soil. In addition, some crops, like legumes, can actually add nutrients back into the soil through nitrogen fixation. This helps maintain the fertility and structure of the soil, ensuring its long-term sustainability for future agricultural use.
