Abstract | [Abstraact]: In irrigated environments the uniformity of the water application has a major effect on the soil water content and the subsequent spatial variation in crop stress and yield. However, the evaluation of sprinkler irrigation uniformity using traditional catch can analyses is resource prohibitive and commonly results in only small grids being used to infer whole field performance. A trial was established in a lettuce crop irrigated with a solid set sprinkler system to evaluate the potential to use electromagnetic sensing for irrigation performance assessment. After crop establishment, the uniformity of the irrigation applications was deliberately modified within one sprinkler plot (9 m x 11 m) by reducing the sprinkler operating pressures. The uniformity of the water applied at each irrigation was measured using a grid of catch cans. The apparent soil electrical conductivity (ECa) was measured |
