AB - 우리나라 밭토양의 토양화학성을 4년 1주기로 정점조사하여 2001부터 2017년까지의 변화를 평가하였다. 밭토양의 화학성분 평균 함량은 pH는 6.1, 전기전도도 0.75 ds m-1, 유기물 함량은 25 g kg-1, 유효인산 615 mg kg-1, 치환성칼륨, 칼슘, 마그네슘은 각각 0.83, 6.4, 1.8 cmolc kg-1 이었다. 유효인산은 2001년 547에서 2017년 657 mg kg-1로 지속적으로 증가하였고 적정범위 상한기준을 약 20% 초과 하였다. 밭토양의 화학성분 적정범위 기준으로 부족, 적정, 과다비율을 구하여 연차별 변이를 분석한 결과 측정 평균값이 증가한 항목 중 과다와 적정범위의 비율도 증가하는 경향을 보였고, 적정범위보다 낮음의 비율은 감소하였다. 유기물함량, 유효인산, 치환성 양이온 과다비율이 증가하는 경향을 보였다. 생산량에 초점을 둔 고투입 농법의 지속적인 추진으로 우리나라 농업환경이 악화되고 있는 시점에서 농업환경변동 실태조사를 통한 농업환경자원 평가체계 구축 및 지표개발 연구가 필요할 것으로 판단된다.BACKGROUND:Monitoring of the dynamic changes of chemical properties in agricultural land is very important for agricultural sustainability. Chemical properties of agricultural soils in Korea have been investigated at four-year interval in the order of paddy, plastic film house, upland, and orchard soils since 1999.METHODS AND RESULTS:Total 8,160 topsoil samples were taken from the upland in 2001, 2005, 2009, 2013, and 2017, respectively. Soil chemical properties such as pH, electrical conductivity (EC), organic matter (OM), available phosphate (Avail. P2O5), and exchangeable (Exch.) cations (K, Ca, and Mg) were analyzed. Soil pH and Exch. Ca contents have increased since 2001. Average concentration of Avail. P2O5 increased from 547 mg kg-1 in 2001 to 657 mg kg-1 in 2017. Average concentration of Exch. Ca in 2017 was higher than the upper limit of its optimal range for upland cultivation. Excess and deficiency of chemical properties of upland soils comply with soil analysis and fertilizer prescription.CONCLUSION:We concluded that excessive nutrient in upland needed to be properly managed with soil test.
