| Abstract/Contents: | "Three greens construction profiles popular in Australia were compared in terms of their hydrological properties under a well established grass cover. The constructions compared were (a) the USGA profile (b) a Uniform Sand profile, similar to the specifications of the University of California profile, and (c) a Modified USGA profile which uses 150mm coarse sand under the 300mm of medium sand. All profiles had a total depth of 450mm. The experimental site was a bowling green with a common playing surface but built in three separate 7m x 41m sections, each section having a different construction profile and an independent drainage system. Saturated drainage hydraulic conductivity (K^D[s) was twice as large at 200mm depth as at 300mm depth; it did not differ between the profiles. Infiltration rates, measured using double-ring and disc permeameters, were highly variable and lower (p<0.05) in the Uniform Sand profile than the USGA and Modified USGA profiles. Infiltration was limited by water repellency of the surface. The change in total water content to 300mm depth, W, during the drainage and drying cycle was represented by the relationship W=atā»^D]b^D]; where t is the time scale of measurements, a is the intercept and b the slope of the drainage curve. Field capacity was attained in approximately the same time (3.7 to 4.7 d) for all profiles. Readily available soil moisture (RASM) was calculated as the difference between total water content at field capacity and at an arbitrary "stress point" of 1 bar metric potential, determined with a pressure plate apparatus. RASM in the top 300mm of the USGA profile was higher (38mm) than in the other profiles (33mm). The larger water storage of the USGA profile was a result of the "perching" of water above gravel in this profile. Despite the different methods of construction, the three greens showed only relatively small differences in hydrological properties which would not be expected to have any impact on normal management requirements. However, differences between field measurements and laboratory determinations (eg, of field capacity) confirm the importance of in situ determination of hydrological properties of greens for optimum irrigation management." |
