Why is monthly soil moisture monitoring valuable for irrigation management?

• A. It helps detect over- or under-watering patterns and informs scheduling to conserve water.
• B. It helps determine soil pH levels
• C. It determines pesticide needs
• D. It replaces ET calculations

Answer: (A)

Tracking soil moisture provides direct feedback on the water available to plant roots. By checking the root zone moisture, you can see how quickly soil dries after irrigation or rain, how long it stays moist, and where moisture is consistently high or low. That information lets you schedule irrigation to match actual plant needs: you water when moisture is dropping to levels that support growth, and you pause when the soil is already sufficiently moist. The result is conserving water, reducing leaching and stress from both drought and over-watering, and promoting uniform root-zone moisture for steady growth. It also supports better irrigation decisions by aligning planned watering with real soil conditions rather than relying on guesses. It doesn’t determine soil pH or pesticide needs, and it doesn’t replace ET calculations; it complements them by showing the actual soil water status. That practical feedback is why monthly soil moisture monitoring is valuable for irrigation management.
