Abstract

Organic fertilizers are divided into natural organic and synthetic organics. The benefits of natural organic fertilizer were reported from the previous researches. The previous researches have reported that clippings are nitrogen source for turfgrass growth. However, the limited research results about clippings as a source of natural organic fertilizers were reported. The objective of the research to investigate effects of liquid fertilizer produced from fermented clippings for creeping bentgrass growth. Liquid fertilizer (LF) produced was used for the research to be compared with urea and two natural organic fertilizers of different source (NO-1 and NO-2). Kentucky bluegrass (Poa pratensis L., Midnight) was used for the study. Turfgrass quality was measured by visual evaluation every two weeks from June to October, 2011 using a scale of 1 to 9 (1=worst, 6=acceptable, and 9=best). LF produced greater turfgrass quality than acceptable quality, especially with the summer period while urea and NO produced lower turfgrass quality than acceptable quality of 6. LF had less quality alteration than urea and NO during the study. Based on the result of the study, LF are more stable to maintain turfgrass quality than urea and NO.

유기질비료(Organic fertilizer)는 천연유기질(Natural organic) 비료와 합성유기질(Synthetic organic) 비료로 구분이 된다. 천연유기질비료의 장점은 그동안의 선행연구를 통해서 많이 보고되어왔다. 그러나 예지물을 이용한 시비효과에 대한 연구결과는 제한적이다. 본 연구는 예지물을 발효시켜 제조된 천연유기질비료로서의 골프장의 fairway 및 athletic fields 에서 많이 사용되고 있는 Kentucky bluegrass 생육에 미치는 영향을 알아보기 위해서 수행하였다. 생초복합비료는 Kentucky bluegrass 로부터 수거된 예지물을 모아 부숙과정 없이 미립자로 분쇄한 후 $28^{\circ}C$에서 약 2개월간 발효시킨 후 생성된 발효액에 유용미생물(Effective Microorganism, EM) 군으로 제조된 활성액을 3% 혼합하여 제조하였다. 잔디에 대한 각 질소의 시비효과는 National Turfgrass Evaluation Program (NTEP)에서 제시한 방법에 준하여 잔디의 품질을 시각적평가를 통해 매 2주마다 조사하였다(1=worst, 9=best, and 6=acceptable). 생초복합비료와 천연유기질비료와의 비교에서는 품질의 변화폭이 일정하고 최소수용품질 이상의 품질을 나타내기에 생초복합비료가 그 효과가 있는 것으로 나타났다. 이 결과는 속효성비료인 urea 와의 비교에서 그 차이가 더 크게 나타났다. 그러나 생초복합비료의 시비 빈도간에 따른 차이는 본 실험에서 나타나지 않았다.
