ABSTRACT

The trend in golf greens construction during the past three decades has been towards putting greens with at least 90% sand and limited amounts of silt, clay, or organic matter. High sand based systems typically have low cation-exchange capacity (CEC) and large saturated hydraulic conductivities (>30 cm h^–1), thus, are prone to NO^–₃ leaching and possibly contribute to ground or surface water contamination. Clinoptilolite zeolite (CZ) has a high CEC (160 cmol kg^–1), a large affinity for NH⁺₄ ions and water molecules that may reduce N leaching on sand based putting greens. The impact of CZ amendment of sand putting greens on N leaching and N uptake by creeping bentgrass (Agrostis stolonifera L.) was determined. The lysimeter method was used for growing creeping bentgrass in the greenhouse to determine NO^–₃ and NH⁺₄ leaching potential and fertilizer N use efficiency. Four N levels (0, 98, 196, and 293 kg NH⁺₄-N ha^–1) and two media, sand-CZ mix (9:1, w/w), and unamended sand, were included as treatments. Sand plus CZ had a lowered concentration of NO^–₃ and NH⁺₄ in leachate while doubling the water retention capacity and increasing CEC 200 fold. The greatest reduction of N leaching was found from lysimeters amended with CZ at the highest N rate. Nitrate and NH⁺₄ leaching was 86 and 99% lower, respectively, than the unamended sand lysimeters. The N fertilizer use efficiency was improved by 16 to 22% with the addition of CZ to sand, depending on N application rate. Amendment of sandy rooting media with clinoptilolite promoted better fertilizer N uptake efficiency and reduced N leaching from a highly leachable soil.
