Question 1 Report

Which of the following is the best way to reduce surface run-off on farmlands?
Answer Details
Providing adequate plant cover is the best way to reduce surface run-off on farmlands. When plants are present, they act as a physical barrier that slows down the movement of water across the soil surface. Plant roots also help to bind soil particles together, making it less likely for the soil to be eroded by surface run-off. This results in improved soil fertility, water conservation, and increased crop yields. Therefore, farmers can use crops that provide good ground cover to reduce surface run-off, such as cover crops, legumes, and grasses.
