Which statement is true regarding Distribution Uniformity (DU)?

• A. High DU indicates uneven irrigation
• B. High DU allows for even irrigation of the root zone
• C. Low DU is always acceptable
• D. DU does not affect irrigation schedule

Answer: (B)

The statement that high Distribution Uniformity (DU) allows for even irrigation of the root zone is accurate because it highlights the significance of DU in irrigation practices. When DU is high, it means that water is distributed evenly across the landscape, ensuring that all areas receive sufficient moisture. This uniformity is crucial for promoting healthy plant growth as it prevents dry spots and overwatered areas, which can lead to root diseases or water wastage. Achieving high DU is essential for efficient water management, as it allows the root zone of plants to absorb water consistently, thereby enhancing plant health and reducing the need for additional irrigation. Good DU contributes to the overall sustainability of landscape practices, particularly in water-scarce regions where efficient water use is a priority.
