Abstract

Recently, concerns regarding the environmental impact due to nutrient input in croplands have increased. Therefore, the government is promoting the introduction of a nutrient management system in croplands to solve the problem of excessive nutrient input. This study was carried out to establish nutrient indicators in regional croplands to facilitate the introduction of the national nutrient management system in Korea. The nutrient load and balance indicators for nitrogen and phosphorus were analyzed for nine provinces (Gang-won, Gyeong-gi, Chung-buk, Chung-nam, Jeon-buk, Jeon-nam, Gyeong-buk, Gyeong-nam, and Jeju). In the correlation analysis between the nutrient load and nutrient balance, the correlation coefficient (r) for nitrogen was 0.2504, which was not statistically significant at the 5% significance level. However, the correlation coefficient for phosphorus was 0.7375, which was statistically significant at the 5% significance level. In the nutrient management index, phosphorus showed mutual compatibility between the nutrient load and the nutrient balance indicators, but nitrogen showed no mutual compatibility between the nutrient load and the nutrient balance indicators. Therefore, utilization of the nutrient balance indicator, reflecting the characteristics of the agricultural environment, was more reasonable as a nutrient management index for regional nutrient management.

최근 농경지 투입양분으로 인한 환경영향의 우려와 함께 하천 등으로 유출되는 양분의 오염부하 관리가 요구되고 있다. 이에 정부는 국내 농지의 양분 과잉 투입 문제를 해결하기 위해 농경지의 양분관리 목표를 설정하여 관리하는 양분관리제도의 도입을 추진하고 있다. 본 연구는 국내 합리적인 양분관리제도 도입을 위한 양분관리 지표 기준을 설정하고자 도 단위의 양분부하와 양분수지 지표를 분석하고 지표별 특성을 비교 검토하였다. 도 단위 질소와 인성분의 양분부하와 양분수지 분석에서 지역별 양분부하 순위와 양분수지 순위가 다르게 나타나, 지역의 양분수준을 평가하는데 있어 양분부하와 양분수지의 두 지표는 서로 상이한 지표 값을 도출하는 것으로 나타났다. 양분부하와 양분수지 간의 상관관계 분석에서 질소성분의 경우 상관관계 계수(r)는 0.2504로서 5% 유의수준에서 통계적 유의성이 없었으며, 인성분의 경우 상관관계 계수(r)가 0.7375로서 5% 유의수준에서 통계적 유의성이 인정되었다. 따라서 양분관리 지표활용에 있어 인성분의 경우 양분부하와 양분수지 간의 상호 호환성이 나타났으나, 질소 성분의 경우 양분부하와 양분수지 간의 상호 호환성이 없는 것으로 나타났다. 따라서 지역의 양분관리 지표로서 농업환경 특성을 반영하는 양분수지 지표의 활용이 합리적인 것으로 평가되었다.
