Abstract/Contents:"Many golf course putting greens and athletic fields have been constructed on high sand content rootzone media as prescribed by the United States Golf Association (USGA). The sand is usually amended with relatively small amounts of various materials, with peat moss being the most common, to improve moisture and nutrient retention while maximizing rootzone drainage, compaction resistance, and aeration. Due to limited supplies, a trend to replace peat with inorganic soil amendments (IOSA) is occurring in the construction of new greens and athletic fields. However, little research as to the long-term (> 5 years) benefits of these materials exists. In 1997, a field study was initiated to investigate the potential of IOSA as a replacement to peat in putting greens constructed in the Southeastern United States. Plots were constructed using a rootzone sand (RZS) meeting USGA specifications alone and the RZS amended at 15% by volume with either Canadian sphagnum peat (CSP), calcined clay (CC), or diatomaceous earth (DE). Creeping bentgrass (Agrostis palustris Huds. X A. stolonifera L. 'L-93) was seeded on 8 October 1997 at 73.3 kg ha-1. Plots amended with CSP established to 95% ground cover 6 months after seeding, which was 3 months prior to plots with either IOSA and 15 months prior to the straight RZS plots. Once established and actively growing, turfgrass color for all plots was generally acceptable (7.0). The bulk density of lab packed RZS was greater (1.61 Mg m-1) than the IOSA mixtures (1.49 Mg m-3), while CSP amended sand had the lowest bulk density (1.41 Mg m-3). In the upper 10 cm of field cores, significantly lower bulk densities were measured in amended plots. Organic matter contents greater than 1% by weight for plots amended with CSP and CC would explain lower bulk density measurements in this zone. Plots amended with CSP had 13 to 31% lower deceleration values than straight RZS and IOSA amended plots, indicating CSP amended plots were associated with softer playing surfaces. Resistance to penetration in the upper 5 cm was variable for the various rootzone mixtures, however, in the lower 20 to 30 cm depths resistance to penetration ranked in the order of CC>DE>RZS>CSP. The addition of CSP to RZS provided for the earliest turfgrass establishment, excellent turfgrass color, reduced bulk density, and lower impact absorption characteristics. Throughout the 3-year duration of this study, CSP was the best amendment for providing turfgrass cover and quality."
