Abstract

This study was conducted to evaluate the availability of livestock manure as functional fertilizer containing micronutrients by investigating the growth and quality of Kentucky bluegrass (Poa pratensis ‘Midnight’). The microelement fertilizer (MiF) contained livestock manure, iron (Fe) and zinc (Zn). Compared with CF, turf color index and chlorophyll index of Kentucky bluegrass in MiF treatment were not significantly different. After applying MiF to Kentucky bluegrass, clipping yield of MiF treatments was 261.0-267.2 g·m-2, which explained significant increase by 20.6-23.4% than that of control (216.5 g·m-2). In addition, nutrient uptake such as N, K, Mg, and Fe was higher than in the control. Correlation coefficient between applied MiF level and the uptake of Ca, Mg, Fe, Zn and clipping yield was significantly positive (P<0.05). These results indicated that MiF application was enhanced the Fe uptake and the clipping yield on the Kentucky bluegrass.
