Abstract

The importance of environment-friendly agriculture is being magnified as a new growth engine industry in pursuit of low carbon, green growth policies. Since 2010, the Korean government has been promoting the supply of customized fertilizers which were manufactured based on chemical properties of agricultural soils. This aims focused to improve the efficiency of fertilizer used and to protect the agricultural environment. In order to provide technical supports for pushing ahead with the environment-friendly agriculture policies, we have estimated the effects of customized fertilization (CF) on growth and yield of rice and fertilizer reduction compared to conventional fertilization (farm practice fertilization) and single-element fertilization. In rice plant growth and rice yield, no statistically significant difference between the three fertilization treatments was observed. The fertilizer reduction rate with CF compared to conventional fertilization of investigated farms was on average 17%, which covered 6% through 33%. With split ratio, CF 70 reduced the amounts of fertilizer ingredient by 5% compare to CF 50. This paper shows that the customized fertilizer application reduced the amounts of fertilizer used in rice cultivation without decrease of yields.

본 연구는 벼 재배에 있어 맞춤형비료 시용 효과를 평가하기 위하여 기존의 3요소 단비 처리 및 일반 관행시비 농가에 대한 맞춤형비료 시용에 따른 벼 생육과 수량 그리고 비료사용량 절감 효과 등을 평가하였다. 처리별 벼 생육 상황은 기존 3요소 단일비료 처리구와 맞춤형비료 처리구간 유의성 있는 차이는 나타나지 않았다. 또한, 벼의 정조 수량에도 3요소구 및 일반 관행 농가와의 차이가 없어 맞춤형비료 시용에 따른 벼 생육 및 수량 저하 문제는 없었다. 반면에 맞춤형비료 시용에 따른 농가의 관행 비료 시용량 대비 절감율은 조사 지역별로 6~33% 범위로 평균 17% 이었으며, 맞춤형비료 분시비율에 따른 비료 성분량은 밀양지역을 제외한 모든 조사지역에서 가지거름을 시용하지 않고 2회 분시한 맞춤형비료 70구가 3회 분시한 맞춤형비료 50구에 비해 상대적으로 적은 것으로 나타났다. 조사지역 전체적으로는 평균 5% 정도 비료 성분량이 적게 사용된 결과를 보였다.
