Slow/Controlled-Release Fertilizer Applications and Nitrous Oxide Emissions from Fairways and Roughs
Benefit of slow/controlled release fertilizers:
The use of slow or controlled-release fertilizers has become very valuable and common practice in maintaining golf course turfgrass. The applications of these types of fertilizers have provided several benefits. First, slow-release fertilizers are a great resource towards suppling adequate amounts of fertilizer without requiring frequent fertilizer applications. With a need for fewer applications, superintendents save time and fuel while freeing crews for other projects. In addition, controlled-release, consistent N delivery reduces the risk of turfgrass foliar burn and helps turfgrass take up more nutrients while reducing the amount lost to the environment through leaching, denitrification, runoff, or volatilization. The long-term benefits of these types of fertilizers are appreciated.

Surfactants for water conservation and their impact on soil health
Soil surfactants have been used in regular turfgrass maintenance programs to increase irrigation efficiency, because their use has been shown to increase uniformity and improve the moisture retention in the root zones (Alvarez et al., 2016; Kostka and Bially, 2005; Leinauer et al., 2001; Leinauer et al., 2010; Leinauer and Devitt, 2013; Mitra et al., 2005). Due to their ability to weaken the surface tension, wetting agents permit the penetration of water not only into repellent rootzone areas but also into the meso and micropores of soils. Thus, in addition to offering remediation of LDS and hydrophobic soil conditions, soil surfactants may also help to reduce irrigation requirements by improving water use efficiency. Several studies have documented improved turfgrass performance under drought or decreased irrigation when soil surfactants were applied (Alvarez et al., 2017; Cisar et al., 2000; Kostka, 2005; Kostka et al., 2007). Currently, 94% of golf courses in the United States have incorporated soil surfactants into their regular maintenance protocols (Gelernter et al., 2015).

Selection of Water Saving Kentucky Bluegrass and Tall Fescue for Colorado Turfgrass Industry & Relationships of Soil Analysis, Turf Quality, and Shoot Analysis of Kentucky Bluegrass Under Effluent Water Irrigation on Golf Courses
Dr. Yaling Qian, Associate Professor, Department of Horticulture and Landscape Architecture Colorado State University, September 2019
Project 1: This on-going RMEGI supported research began in 2017 to compare turfgrass quality and growth of 15 different Kentucky bluegrass entries, 19 tall fescue entries and 1 perennial ryegrass line under different irrigation treatments to determine relative drought resistance of the different entries and document the water quantity needed for each entry to maintain acceptable and desirable turf quality.
Project 2: Research was conducted on eight golf courses in the semiarid Front Range of Colorado to determine the effects, if any, of watering with effluent water on turfgrass and the degree of accumulation of different minerals or salts in turfgrass shoots when effluent water is used for irrigation. Three courses have used effluent water irrigation for 10 years, three courses for 18-26 years and two courses have used effluent water irrigation for 15 and 18 years. Turf quality of Kentucky bluegrass was evaluated on 25 roughs from the above-mentioned golf courses and analyzed for a variety of mineral concentrations.

Efficacy and Safety of Proxy-rate Programs in Winter for Annual Bluegrass Seedhead Management Adam Van Dyke, M.S., CPAg, Professional Turfgrass Solutions LLC
This RMEGI supported research was conducted from November 2017 until May 2018 on a 70:30 annual
bluegrass: creeping bentgrass putting green at Murphy Creek Golf Course in Aurora, Colorado. Proxy® (Bayer)
was applied at two winter timings, and at different rates, to evaluate the effectiveness of making early
applications compared to just making traditional spring applications for controlling seedheads of annual
bluegrass. Proxy was applied at a pre-snow timing (before snow cover) on November 20, 2017 and at a postsnow
timing (after snow melt) on March 8, 2018.
