Abstract
아스파라거스 재배농가의 토양 내 화학성을 분석하여 금후 토양관리의 기준을 확립하고자 본 연구가 수행되었다. 전국 아스파라거스 재배농가 평균 토양화학성은 pH 6.1, EC, 3.7 dS m-1, OM 40.5 g/kg-1, 유효인산 1,118 mg/kg-1, 치환성양이온으로 칼슘 10.7 cmol+/kg-1, 칼륨 2.4 cmol+/kg-1, 마그네슘 3.2 cmol+/kg-1이었다. 전체적으로 토양 내 EC,OM, 유효인산, 치환성양이온의 함량이 높았으며 pH는 적정범위에 있었다. 지역별 토양화학성은 큰 차이가 있었다. 이러한 차이는 토양특성, 시비방법, 재배 연차 등에 따른 것으로 판단되었다. 특히 당진군의 경우 토양 EC가 12.6 dS/m-1으로 높았으며 이는 10년 이상의 재배연차와 지속적인 퇴비 및 가축분뇨액비의 시용에 기인한 것으로 판단되었다.
This study was conducted to analyze the soil chemical properties of asparagus farmers and to establish future soil management standards. The average soil chemistry of asparagus farms are pH 6.1, EC 3.7 dS/m-1, OM 40.5 g/kg-1, effective phosphate 1,118 mg/kg-1, calcium 10.7 cmol+/kg-1, potassium 2.4, and magnesium 3.2. Overall, the content of EC, OM, phosphoric acid and substituting cations in the soil were high, and the pH was in the proper range. There was a big difference in soil chemistry by region. These differences were attributed to soil characteristics, methods, and year of cultivation. Especially in Dangiin, soil EC was high at 12.6 dS/m-1. It was judged that this was due to the continuous application of compost and cultivation of livestock manure liquid fertilizer with the cultivation year of more than 8 years.
