| Abstract/Contents: | "Inorganic soil amendments have been suggested for use in turf to alleviate soil compaction, to increase the water retention and hydraulic conductivity, and to improve many other soil physical properties. No single soil conditioner can have all those properties. They, therefore, should be used in a site- and case-specific way. This study was to determine the effects of four different inorganic soil amendment materials: Bio-ceramic, Profile, Axis, and Bio-Flex-A-Clay on the soil hydraulic parameters of a sand-based media. The inorganic materials were added to a USGA sand-based green at 15% v/v during construction in 1996. The study was conducted during the 1997 and 1998 seasons. A laboratory study using a peat amendment and a pure sand control was also conducted in the spring of 1999. Data collected on the field areas included saturated hydraulic conductivity (K^D[sat), water retention, water release curves, bulk density, and total porosity on both undisturbed anbd recompacted samples collected from the treated plots one and two years after establishment. The Profile treatment had significantly higher cation exchange capacity (CEC) than the control in both years. Bio-ceramic had a higher CEC and Bio-Flex-A-Clay had lower CEC than the control in 1997. Profile increased the K^D[sat significantly in the recompacted and undisturbed samples in 1998. Axis increased water retention in both recompacted and undisturbed samples. K^D[sat of all treated plots was reduced by 75% in November of 1998. The K^D[sat values in the spring of 1999 increased from the low levels of 1998 by 19.2% (Bio-Flex-A-Clay), 43.5% (control), 58.6% (Bio-ceramic), 72.1% (Profile) and 81.7% (Axis). The changes of K^D[sat over the winter may have been induced by freezing and thawing that occurred over the winter. This hypothesis was further tested in the laboratory in a freeze-and-thaw study conducted in 1999. The bulk density of sand mixed with Bio-Flex-A-Clay, peat, Axis and Profile was decreased by 10.7%, 7.2%, 2.5% and 2.2% respectively following a freeze-and-thaw cycle. The decrease of bulk density in the control and in sand treated with Bio-ceramic was negligible." |
