This study was conducted to evaluate the availability of livestock manure as functional fertilizer materials by investigating the growth and quality of creeping bentgrass after applying microelement fertilizer (MiF) containing livestock manure, iron (Fe) and zinc (Zn). Treatments were as follows. No fertilizer (NF), control fertilizer (CF), M1 (CF+1.0 mL m-2 MiF), M2 (CF+2.0 mL m-2 MiF), M3 (CF+4.0 mL m-2 MiF), and NM (2.0 mL m-2 MiF). Compared with NF, growth and quality of creeping bentrgass in NM treatment were not significantly different. After applying MiF, the quality and growth of creeping bentgrass and nutrient content in its leaf was similar to those of CF. However, correlation between Fe uptake amount in the turfgrass leaf and MiF treatments was significantly positive (

Fig. 1. Turfgrass density of creeping bentgrass applied with microelement fertilizer containing iron and zinc.Turfgrass density was investigated on November 3. Error bars indicates standard deviation and different letters indicates significant different at ≤0.05 level according to Duncan’s multiple range test. Treatments were as follows. NF: No fertilizer; CF: Control fertilizer; M1: CF+1.0 mL m microelement fertilizer containing iron and zinc (MiF); M2: CF+2.0 mL m MiF; M3: CF+4.0 mL m MiF; NM: 2.0 mL m MiF. CF supplied was applied at 3.0 g N ai m rate on June 30, August 4, September 8, October 15, and November 3, respectively. The MiF treatments were implemented 12 times on June 8, June 22, July 6, July 21, July 20, August 4, August 17, August 31, September 8, September 23, October 15, and October 20.
