| Abstract/Contents: | "Laboratory assessment of saturated hydraulic conductivity (Ksat) of sand root zones before construction of golf putting greens is often extrapolated to rather precise expectations of field water infiltration. This study compared pre-construction Ksat of mixes to water infiltration of 4-yr old creeping bentgrass putting greens in two microenvironments. Root zone mixes containing various sand size distributions were arranged in a randomized incomplete block design nested over two micorenvronments. Double-ring infiltration through the 0- to 50-mm surface depth was measured. Pre-construction Ksat ranged from 407 to 937 mm h-1, with root zones ranked greatest to lowest: coarse, coarse-medium, medium = medium-fine 2, and medium-fine 1. As expected, water infiltration was dramatically lower than Ksat. Greater infiltration in the enclosed microenvironment was only observed on coarse sand (37 mm h-1) compared to other root zones that had infiltration of 9 to 23 mm h-1. Infiltration rates of root zones in the open microenvironment ranged from 12 to 68 mm h-1 and were ranked greatest to lowest: coarse-medium, medium, medium-fine 1 = medium-fine 2. Thus, expectations that pre-construction root zone Ksat serves as a precise index for water infiltration of putting greens are unreliable." |
