Final answer:
Crop rotation is an effective mitigation activity for farms. It improves soil nutrient levels and breaks crop pest cycles, reducing the need for pesticides. Additionally, it helps diversify crops and protect water quality.
Step-by-step explanation:
Crop Rotation
Crop rotations are planned sequences of crops over time on the same field. Rotating crops provides productivity benefits by improving soil nutrient levels and breaking crop pest cycles. Farmers may also choose to rotate crops in order to reduce their production risk through diversification or to manage scarce resources, such as labor, during planting and harvesting timing. This strategy reduces the pesticide costs by naturally breaking the cycle of weeds, insects and diseases. Also, grass and legumes in a rotation protect water quality by preventing excess nutrients or chemicals from entering water supplies.
