Distribution Uniformity (DU) is a measure of how evenly water is applied across a field during irrigation. For example, if one inch of water is applied in one part of the field and only half an inch is applied in another part of the field, that is poor DU. In short, bad DU means that either too much water is applied resulting in unnecessary expense, or too little water is applied, causing stress to crops. Better DU means more profits through cost savings, healthier crops and better yields.
