    Soil water tension (SWT) represents the magnitude of the suction (negative pressure) the plant roots have to create to free soil water from the attraction of the soil, and move it into the root cells. The dryer the soil, the higher the suction needed, hence, the higher SWT.

Cooperative Extension classroom and field demonstration Size: 1MB. Irrigation System Evaluation Poor distribution uniformity and low irrigation efficiency have negative impacts on the benefits and profitability of irrigation.

An evaluation utilises selected measurements of system performance (and management) to identify causes of any poor performance and how these deficiencies can be rectified. In order to calculate the in-field distribution of water by the irrigation system, otherwise known as the uniformity, to work out the efficiency and to determine how adequately the irrigation system met the irrigation target application, specific evaluation procedures for specific irrigation systems must be.

An irrigation system’s uniformity of water distribution or distribution uniformity (DU) is a key measurement of a system’s water use efficiency. If water is not distributed evenly or uniformly on a field, areas receiving less acre-feet of water will have poorer plant health and reduced crop yields Farm irrigation system evaluation book to avoid reduced yields, the system must.
