Abstract

Sustainable farming systems have remarkably increased in Korea due to the increase of environmental concerns caused by the conventional systems. This study was performed on eight-year-old 'Niitaka' pear tree s to investigate the effects of different organic fertilizers on soil chemical and microbial properties and leaf and bud developments. Treatment and applications included 10 kg of rice bran (RB), 10 kg of coffee bran compost (CBC), 10 kg of Chitin incubated compost (Micro keeper$keeper^{(R)}$, CIC), and 30 kg of the mixture of the RB, CBC, and CIC (RCC). Control received 60 g of NPK (16-11-12) chemical fertilizer. The organic fertilizers increased organic matter, nutrient concentrations such as P, K, Ca, and Mg, and microbial biomass in soils compared to the control. RCC had the greatest specific leaf weight (SLW), and the other treatments did not have a significant difference for the SL W. Leaf P and K concentrations were different among the treatments, but they were not affected by the amounts of the soil nutrients. No differences were observed in the leaf Ca and Mg concentrations in the treatments. Organic fertilizers had greater chlorophyll contents than the control but had similar flower bud characteristics to the control.

생산성 위주의 집약적인 농업방식으로 인한 토양오염과 환경파괴가 갈수록 심화되어 현재 친 환경재배의 요구가 날로 중요시되고 있다. 본 실험에서는 배 과원의 토양에 여러 가지 유기질 비료를 시용하였을 경우 토양의 화학성 및 미생물성 그리고 엽형질과 엽눈의 변화를 조사하였다. 개화 전 8년생 '신고' 배 과원에 쌀겨, 커피박퇴비, '키친퇴비(미생물 지킴이'$^{(R)}$) 및 세 가지 유기질 복합처리구를 배치하고 각각 주당 10kg, 10kg, 10kg, 30kg씩 살포하였고 대조구는 NPK 복합비료로 주당 60g을 살포하였다. 유기질 비료 처리 대조구보다 토양 내 유기물과 P, K, Ca, 그리고 Mg 농도 및 미생물 생체량(biomass)을 증가시켰다. 엽비중은 유기질 복합처리구에서 가장 높았고, 나머지 처리간에는 유의성이 없었다. 엽내 P와 K 농도는 처리간에 유의성이 나타났지만 토양 내 무기성분 농도 수준과는 관련성이 없었다. 엽내 Ca와 Mg는 처리간에 유의성이 없었다. 엽내 엽록소 함량은 모든 유기질 비료 처리구에서 대조구보다 증가하는 경향을 나타냈으나 꽃눈의 형질변화에서는 유의성이 나타나지 않았다. 본 실험은 1년간 유기질 퇴비를 통한 배 과원의 토양과 수체를 조사한 것으로 유기질 비료와 대조구간에 명확한 차이가 나오지 않는 경우도 있어서, 장기간에 연용에 따른 토양 특성 변화와 이에 따른 수체생장에 걸친 연구가 필요할 것이다.
