| Abstract/Contents: | "Best management practices for water conservation in lawns include using improved irrigation technologies and adjusting mowing heights to increase water-use efficiency without sacrificing turfgrass quality. Smart irrigation controllers have demonstrated their ability to effectively reduce water use and raised mowing heights have also demonstrated their positive effects on turf during periods of drought stress. The combined effects of smart irrigation and high mowing heights could further reduce the water and mowing requirement of Kentucky bluegrass (Poa pratensis L.) turf, a high-input turfgrass species predominantly utilized in Minnesota lawns. The objectives of this research are to 1.) Investigate the combined effects of mowing height and irrigation on Kentucky bluegrass lawn quality and 2.) Estimate the environmental impacts regarding water savings, and potential reductions in labor requirements and CO2 emissions from mowing. This trial ran from 16 June to 28 September 2019. Kentucky bluegrass was mowed once weekly, at 3.8, 6.4, or 8.9 cm. Irrigation treatments included a traditional controller (no runtime adjustment) and a smart-irrigation controller (runtime adjustment based on automatic seasonal adjustment feature), and was programmed to apply 8.4-mm water on odd days. Frequent precipitation and a midsummer-N application likely contributed to no significant effects from irrigation on turf quality, turf height at time of mowing, and clipping yield. Smart irrigation significantly reduced water use with an average monthly irrigation reduction of 22%. Acceptable turf quality was observed across all mowing heights during July, August, and September; and clipping yields were similiar among the mowing heights during August and September. The lowest mowing height violated the one-third-rule more frequently than the two higher mowing heights. Higher heights of cut could reduce labor requirements and CO2 emissions as mowing frequency could potentially be reduced from once weekly. This trial will be repeated during June-Sept in 2020 and 2021." |
