摘要

Analysis of the particle size distribution of Maui and Oahu glass sands (recycled glass) and an imported silica sand indicated that only the Oahu glass sand met USGA guidelines for golf green construction without additional screening. Bulk density,total porosity, capillary pore space, air-filled pore space and water retention capacity of the silica and Oahu glass sand alone and with 4:1 (v:v) mixtures of 8 sources of organic matter were measured. Total porosity, capillary porosity, total air-filled porosity and water retention capacity in the various mixtures of silica sand were lower than the USGA recommendations for putting greens. Organic matter-Oahu glass sand mixes had the desired bulk density and total porosity for putting greens in most instances, although performance of specific organic materials and composts varied with individual tests. Water retention capacity (or capillary porosity) and air-filled porosity of glass sand/organic matter mixtures were beyond the recommended range. Macadamia husk compost and cattle manure compost appeared to have the greatest potential of the organic materials in this study. Additional testing is required to determine the suitability of specific organic materials as a substitute for peat moss. Common bermudagrass (Cynodon dactylon) turf grew satisfactorily in all of the different mixtures.
