Which method can effectively reduce runoff in an irrigation system?

Using cycle and soak scheduling is an effective method for reducing runoff in an irrigation system because it allows water to be applied in intervals rather than all at once. This approach involves splitting the total watering time into shorter cycles with breaks in between, allowing the soil to absorb the water, thereby minimizing surface runoff.

When water is applied too quickly or in large amounts, the soil may not be able to absorb it efficiently, leading to excess water that runs off the surface. Cycle and soak scheduling enhances soil infiltration rates and ensures that the water penetrates deeper into the soil profile, promoting healthier root growth and reducing wasted water.

In contrast, continuous watering and watering all day do not give the soil the opportunity to absorb the water effectively, potentially leading to significant runoff and ineffective irrigation. Watering during high winds can exacerbate the issue by causing the water to drift away from the intended area, ultimately wasting water and increasing runoff.
