Abstract/Contents

Abstract: As a response to shrinking supplies of potable water, treated effluent has become an important water source and a common practice of turfgrass irrigation. Decentralized water treatment systems can produce water with adjusted level of nitrate in the effluent water based on the plant’s growing requirements. A greenhouse study was performed at New Mexico State University during summer of 2015 using tailored water (water adjusted for NO3- N at 15 ppm) to establish bermudagrass, buffalograss, and inland saltgrass from seeds. Control containers were irrigated with potable water and received amount of granular Ca(NO3)2 fertilizer to match the total N applied to containers irrigated with tailored water. Leachates from two depths were collected weekly and analyzed for NO3-N, total N, and electrical conductivity. Although the amount NO3-N in the leachate was different for three grasses, none of them had more then 10 mg L-1 of NO3-N in the leachate by the end of the study. Bermudagrass irrigated with tailored water was fastest (24 days after seeding, DAS) to reach 50% cover. However, water quality did not affect DAS to reach 75% cover for bermudagrass and buffalograss.
