Final answer:
An example of a crop rotation pattern is alternating between corn and soybeans, which helps improve soil health by replenishing nitrogen and reduces pesticide costs by disrupting pest cycles.
Step-by-step explanation:
Crop Rotation Pattern Example:
One example of a crop rotation pattern involves alternating between corn (a cereal crop) and soybeans (a legume). By planting corn one season and soybeans the next, farmers can take advantage of the natural benefits each plant provides to the soil and ecosystem. Corn, being a high nitrogen user, depletes the soil of this important nutrient, while soybeans, thanks to the nitrogen-fixing bacteria in their root nodules, can help replenish nitrogen levels in the soil. This rotation pattern promotes soil health and fertility, and reduces reliance on chemical fertilizers. Furthermore, it helps in breaking the cycle of pests, weeds, and diseases, potentially lowering pesticide costs and protecting water quality by minimizing run-off.
