Characteristics of Soils Under Protected Cultivation
시설재배지토양의 이화학적 특성변화
Abstract
Salt accumulation is frequently experienced in soils under protected cultivation. Since protected cultivation does not bave rainfall and resulting infiltration, salt accumulation in the soils is inevitable. In this study, analyzed were chemical characteristics of soils under protected cultivation to investigate the factors which may contribute the salt accumulation. Soil samples were collected from 99 protected cultivation facilities around Ansung-Gun, Gyungki-Do and analyzed for electrical conductivity, PH, organic matter contents. The results showed that there was no significant trend of changes in electrical conductivity and pH along cultivation years. The only factor influencing salt acculmuation was irrigation type. Soils in facilities using drip irrigation showed higher electrical conductivity than these using diversion-hose type irrigation.
