Abstract/Contents: | Presents the results of "a lysimeter trial...carried out under glasshouse conditions in which the physical, chemical and turfgrass growing properties of a pure sand rootzone (SD) were compared with a zeolite-amended sand rootzone (CZ) and a nutrient-loaded, zeolite-amended sand rootzone (NLZ)." Details methods and materials used in the study, stating that "mature discs of browntop bentgrass from an existing pure sand golf green were cut to 20 mm [millimeters] depth and 100 mm diameter. These discs were planted in 100 mm diameter plastic lysimeter tubes of 450 mm length, each tube containing 230 mm rootzone sand (as appropriate) overlying 200 mm 'Grade 6' gravel chip. Turf was allowed to establish in the top of each lysimeter before commencing the trial." Lists four management stages used in the experiment: nutrient stress only, fortnightly fertilizing and leaching, nutrient stress only, and moisture stress only. Reports that "zeolite-amended sand was shown to offer nutrient and moisture retention benefits relative to a pure sand rootzone." Concludes that "rootzones amended with zeolite were clearly able to buffer against times of nutrient and moisture stress for period [periods] of up to approximately two weeks. However, results from this trial suggest that further work should be carried out to quantify the precise management required to optimise [optimize] the performance and benefit of nutrient-loaded, zeolite-amended sand rootzones, with respect to fertiliser [fertilizer] management." |
