| Abstract/Contents: | "Properly chosen sands for golf green and athletic field construction will undergo less compaction, but may have poor water-holding capacity and a low cation exchange capacity (CEC). Amendments often are added to sand during construction to improve growing conditions. The objectives of this research were to investigate the effects of organic and inorganic soil amendments on the growth of creeping bentgrass (Agrostis palustris Huds) `Crenshaw' established on a sand-based media in the glasshouse under stressed and unstressed conditions. The organic amendments, hypnum moss peat, Dakota reed sedge peat, and Irish moss peat were added to the sand at 1% on a dry weight basis (approximately 10% v/v) of the sand mix. The inorganic amendments, Axis (a diatomaceous earth), Profile (a porous ceramic clay,) Flex-A-Clay (a polymer coated sand), and Bio-ceramic (a ceramic material) were added at 10% v/v. An additional Bio-ceramic treatment at 5% v/v also was included. Following establishment, the grass was subjected to water, nitrogen (N), and high temperature stress. The organic amendments improved visual quality, clipping yield, and root growth in both unstressed and stressed conditions. Dakota peat was the most effective of the organic materials. The inorganic amendments did not improve clipping yield or root growth in unstressed conditions. In water-stressed conditions, all inorganic materials except Profile increased total clipping yield by 72 to 136%. The Bio-ceramic and Flex-A-Clay increased root dry weight by 70% in water-stressed conditions. Under high temperature stress (35/30 C day/night), all inorganic materials except Profile increased total plant weight at termination. Dakota peat was the only organic material to increase total plant weight in the high temperature study. The most effective treatments on the growth of creeping bentgrass were Axis among inorganics and Dakota peat among organics under high temperature stress. While peat remains the most effective amendment for sand greens, inorganics would be of potential benefit, particularly under stressed conditions." |
