The Effect of Composted Liquid Manure on the Growth of Zoysiagrass

Abstract

This study was conducted to evaluate the effect of developed composted liquid manure(DSCB), which was produced by adding N, P, and K to composted liquid manure(SCB), on the growth of zoysiagrass. Two different N sources used in DSCB were ammonium sulfate(DSCB-A) and urea(DSCB-U), respectively. Fertilizer treatments were designed as follows; non-fertilizer (NF), control (CF; chemical fertilizer), DSCB-Al(200 mlm -2 DSCB-A), DSCB-A2(250 mlm -2 DSCB-A), DSCB-U (250 mlm -2 DSCB-U) and CF+SCB(CF+250 mlm -2 SCB). In zoysiagrass, turf color index, chlorophyll index, dry weight and nutrient content were measured. Turf color index and chlorophyll index in DSCB and SCB treatment were increased by 1~3% and 14~28% than those of NF, respectively, and in DSCB-A1, DSCB-A2 and CF+SCB increased by 7~12% than those of CF. As applied with DSCB and SCB, the dry weight of DSCB-A1 and DSCB-A2 was increased by 25% and 19% in than CF, respectively and their nitrogen uptake by 19% and 6%. Evaluated with turf quality and growth, DSCB-A1 was the best and the most efficient in all treatments. These results indicated that application of DSCB-A1 promoted turf quality and growth of zoysiagrass by stimulating a nitrogen uptake, so that it was expected to replace to chemical fertilizers.
