This study was conducted to evaluate effects of leaf mold on the physicochemical properties of root zone and the early growth of perennial ryegrass (Lolium perenne Schreb). The blending ratios of soil amendments were 0, 10, and 20% (w/w) incorporated with sand which met to the USGA (United State of Golf Association) recommendation. In the root zone blending with leaf mold, pH was decreased than control while increased electrical conductivity (EC), total nitrogen (T-N), available phosphate (Av.-P2O5), exchangeable potassium (Ex-K) and cation exchangeable capacity (CEC). After blended with leaf mold, it was improved soil physical factors like capillary porosity, air-filled porosity, and total porosity and growth factors like shoot length and the dry weight of shoot and root. The growth of turfgrass was positively correlated with CEC, porosity, and soil nutrients such as T-N, Av.-P2O5 and Ex-K (p<0.01). These results indicated that the application of leaf mold was improved the growth of perennial ryegrass by prompting CEC and porosity in the root zone and by enhancing soil nutrients.
