| Abstract/Contents: | "Root zone depth of golf greens will not only affect the cost of construction, but also the criteria of materials to be used. The objective of this study was to investigate the hydraulic properties as affected by root zone depth, sand particle size, organic amendments, and wetting directions. Two sand sources and three mixtures of the sands with reed sedge peat were tested in this study at seven soil depths, 10, 20, 30, 40, 50, 60, and 80 cm. Water content was monitored at 5-cm intervals of the soil profile and matric potential was measured at the soil surface after the root zones were saturated with water from the top and bottom, respectively. Based on matric potential measurements, capillary connections broke at 40 cm tension for Sand I and Sand II, respectively. Whereas mixing 5% (v/v) peat extended the breaking tension of Sand I and Sand II to 50 and 56 cm, respectively. Adding 15% peat (v/v) to Sand II increased the breaking tension to 66 cm. The greatest water content difference due to wetting direction at the same tension was 7% for the mixture of Sand I/5% peat. Total volume of water in the root zone integrated from the van Genuchten equation showed significant differences when the root zones were deeper than 20 cm. The results showed that both water availability and supply capacity are important for deciding the root zone depth." |
