Catch can audits measure sprinkler performance, while using a portable soil moisture sensor will measure the effectiveness of the irrigation. Both methods are valid and help correlate sprinkler performance with soil moisture uniformity that affects irrigation scheduling and ultimately the appearance of the turfgrass.

Online course from the Irrigation Training & Research Center.Two of the most important concepts in landscape irrigation are distribution uniformity and precipitation rate. DU refers to how evenly water is applied to a landscape. DU is used to measure the performance of an existing irrigation system and is determined through a catch can test. Precipitation rate identifies the rate at which irrigation water reaches the ground surface, and is affected by sprinkler flow rate and area of coverage. PR is an important value that is used in both system design and irrigation scheduling. This class does not qualify for TCEQ.
