| Abstract/Contents: | Presents a study initiated during 2008 to "(1) evaluate the soil chemical properties such as cation exchange capacity (CEC), mineralizable N [nitrogen], and pH [potential hydrogen] as affected by treatments during the grow-in period and age of the putting green," and "(2) analyze the decomposition of soil organic matter (lignin and cellulose) and to understand its spatial distribution and the effects on soil chemical properties." Details methods and materials used during the experiment, noting that "four-inch deep cores of soil samples were collected from each plot and subdivided evenly into 12 layers. Soil pH, cation exchange capacity (CEC), total C [carbon], total N, and mineralizable N were measured for each layer." Reports that "the initial differences of soil chemical properties disappeared due to topdressing practice over a period of 6 years at the top of the rootzones." Concludes that "results of the study verified the potential of using DRIFT-NIR [diffuse reflectance Fourier transform infrared spectroscopy in the near-infrared] and DRIFT-MIR [in the mid-infrared] to predict soil chemical properties of sand-based turf soil, however model robustness may be affected by sampling depth." |

| USGA Summary Points: | Generally, soil pH increases and soil CEC and mineralizable N decreases from the top to the bottom of the soil profile across years and treatments. By the end of six years, sand mixtures and establishment fertilization regime had no effect on soil chemical properties investigated except EC, which was higher in sand/peat/soil rootzones. The initial differences of soil chemical properties disappeared due to topdressing practice over a period of 6 years at the top of the rootzones especially in the 0- to 2- cm layer. MIR and NIR calibration models for total organic C, total N, CEC and EC resulted in prediction with R2 > 0.80. MIR outperformed NIR for total organic C, total N and pH. EC was better calibrated by NIRS. MIR and NIR had equal accuracy for CEC. Subsets separated by depth failed in calibration and mutual prediction, suggesting that calibration robustness could be largely affected by OM. |
