Which of the following is NOT a benefit of proper irrigation?

The correct answer identifies increased pest activity as not being a benefit of proper irrigation. Proper irrigation systems are designed to provide the right amount of water to crops, which enhances growth and crop production while also promoting healthier soil conditions. Proper irrigation practices can lead to a reduction in soil erosion by maintaining soil structure and moisture levels, preventing washout during rain events.

Efficient water usage is a fundamental goal of proper irrigation, ensuring that water is applied where it is needed, minimizing waste and promoting sustainability. Conversely, increased pest activity is generally a concern associated with irrigation, as overly wet conditions can create a favorable environment for pests and diseases, thereby negatively affecting crop health. Proper irrigation promotes benefits that enhance agricultural productivity while managing water resources effectively, unlike the impact of pests, which can harm crops and reduce overall yield.
