What is an Irrigation System Evaluation?
To determine the performance of a center-pivot irrigation system, some undercover work is needed. • Interview the irrigator, the person running the irrigation system; determine how the system is operated. • Closely observe the system as it operates; measure its performance. • Use a catch-can analysis to determine how uniformly (or not) the system applies water. By this process, an irrigation system evaluation results in an Irrigation Water Management (IWM) Plan. This plan: • Promotes desired crop response (higher yields) • Conserves water • Minimizes water quality degradation • Minimizes irrigation-induced soil erosion • Promotes efficient, safe application of agricultural chemicals & fertilizer While it sounds complex, the Irrigation System Evaluation is actually a logical examination of the irrigation system, its components and operation. For private landowners who have invested a large amount in the equipment and incur significant costs in pumping water, an IWM plan can ensure lando
