국내 유통중인 가축분퇴비의 품질 특성 = Analysis of Commercial Organic Compost Manufactured with Livestock Manure

다국어 초록 (Multilingual Abstract)

The contents of total nitrogen(T-N), phosphate(T-P2O5), and potash(T-K2O) are important factors to determine the application rate of the livestock compost to prevent nutrients accumulation and maintain their appropriate levels in arable lands. The concentrations of nutrient, organic matter, salt, water content, heavy metal in livestock compost in circulation were investigated with 659 samples from 2016 to 2017. In order to investigate the fluctuation nutrient contents of livestock composts with the same product name, 19 samples were collected and analyzed T-N, and T-P2O5, and T-K2O concentration during two years. The mean levels of T-N, T-P2O5, and T-K2O in livestock composts of from 2016 to 2017 were 1.73%, 1.88%, and 1.66%, respectively. The average contents of organic matter, water, and salt were 38.9%, 40.9%, and 1.2%, respectively. There were found that the maximum concentrations of Cr, Ni, Cu, and Zn in some livestock composts were exceeded the criteria of the official standard of commercial fertilizer. The maximum variation coefficient of T-N, T-P2O5 and T-K2O content of livestock composts was found to be 24%, 27%, and 50% on average, respectively. In order to manage the nutrients in agricultural soils, it will be reasonable that the error range of T-N and T-P2O5 content in livestock composts should be recommended to be 27% in mean as variation coefficient in case of displaying the nutrient element in liverstock compost.

국문 초록 (Abstract)

농경지에서 양분 집적을 예방하고 적정한 수준으로 유지하기 위해 가축분퇴비의 투입량을 결정할 때 총질소, 총인산, 총칼리 함량은 매우 중요한 인자이다. 그래서 가축분퇴비의 비료성분을 포함한 유기물, 염분, 수분, 중금속의 함량을 조사하기 위해 2016년부터 2017년까지 시판된 가축분퇴비 659점을 수거하여 분석하였다. 그리고 수거 시기별 로 동일 상품명을 지닌 가축분퇴비의 비료성분의 변동폭을 조사하고자 19개 시료를 2년에 걸쳐 3회 수거하여 총질소, 총인산. 총칼리 함량을 분석하였다. 2016년부터 2017년까지 조사된 가축분퇴비의 총질소, 총인산, 총칼리의 평균 함량은 각각 1.73%, 1.88%, 1.66%였고, 유기물, 염분, 수분의 평균 함량은 각각 38.9%, 40.9%, 1.2%로 나타났다. 일부의 제품에서 크롬, 구리, 니켈, 아연의 최대 함량은 비료공정규격의 적정기준 범위를 초과하는 것이 나타났다.
그리고 동일 상품명을 지닌 가축분퇴비의 총질소, 총인산, 총칼리의 변이계수 값은 각각 24%, 27%, 50%로 총질소와 총인산의 변이계수는 유사하였고, 총칼리는 가장 크게 나타났다. 이로부터 농경지의 양분관리를 위해 가축분퇴비의 총질소와 총인산의 비료성분을 표시할 경우에 시판되는 가축분퇴비에 대해서는 평균값에 오차범위를 변이계수 27%로 제시하는 것이 타당하다고 생각된다.
