2016 TL Irrigation Seminar: Auditing: Soil Moisture vs. Catch Cans

Presented by Brian Vinchesi, CIC, CID, CGIA, CLIA, CLIM, CLWM

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.

ITRC: Distribution Uniformity & Precipitation Rate

Intermediate | Landscape (1.5 CEUs)

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. This class does count for 1.5 New Jersey CECs/WC and 1.5 North Carolina CEs.

ROI of Improving Drip Irrigation System Distribution Uniform

This session will discuss the magnitude of drip irrigation in the United States and California and the importance of using distribution uniformity measurements to assess existing drip irrigation system performance. We'll discuss how DU is measured, the results of DU measurements taken to date in California and the potential implications of poor DU in terms of input costs, foregone yield/quality and environmental implications. Attendees will also learn about two efforts underway to improve poor on-farm drip irrigation system DU.
