2. Minimum allowable depletion

3. Maximum allowed depletion

4. Adequate moisture distribution

The correct answer is: Maximum allowed depletion

MAD in irrigation terminology stands for Maximum Allowed Depletion. This concept is crucial in irrigation management as it refers to the maximum amount of soil moisture that can be depleted from the root zone before irrigation should take place. Understanding MAD helps ensure that plants receive adequate water, preventing stress and optimizing growth. By knowing the maximum allowed depletion, irrigators can determine the proper timing for watering and amount needed, which contributes to efficient water use and conservation. This term aids in managing watering schedules effectively, balancing crop needs with resource availability. The focus on maximizing efficiency and encouraging healthy plant growth makes MAD a vital consideration in irrigation practices.
