| Abstract/Contents: | "This project is designed to i) improve recommendations for sand particle size distribution and the depth of the root zone by consideration of the microenvironment, ii) evaluate composts as organic additives and inorganic products for root zone mixes compared to peat sources, iii) assess the potential of various root zone mixes to reduce management and resource inputs, and iv) monitor the physical, chemical, and biological changes that occur in root zones as greens mature for understanding the factors that contribute to the success or failure of greens. Ten sand mixes have been constructed to give a wide range of size distributions falling with the USGA's recommendations for root zone mixes. Packed cores of the sand mixes have been made, and characterization of the sand mixes in terms of physical properties is underway. Saturated hydraulic conductivity has been measured for the ten sand mixes (without amendments); all are above the lower acceptable limit, and six of the ten mixes are above the upper acceptable limit for the accelerated range of saturated hydraulic conductivity. As expected, correspondence of sand size distribution with saturated hydraulic conductivity was evident. Air-filled porosity at 40 cm tension was found to be within or slightly above the range recommended by the USGA. It was evident that air-filled porosity at 40-cm water tension did not completely measure porosity responsible for saturated hydraulic conductivity. Other physical properties are currently being measured. Irish moss peat, sphagnum moss peat, reed sedge peat, and sewage sludge products have been obtained as organic matter sources and are in the process of being characterized. Leaf compost and mushroom compost will also be obtained for characterization and inclusion in text mixes. Physical measurements of sand mixes with organic amendments will follow in the near future. Laboratory assessment of the sand mixes alone and in combination with amendments will be complete spring of 1997. Based on these laboratory data, root zone mixes having a range of characteristics will be identified for study in the two microenvironments of the field research facility at North Brunswick, New Jersey. It is anticipated that putting green construction will be completed in late summer of 1997. Therefore, turf grow-in will be performed over the fall, winter, and spring of 1997-1998." |
