Abstract
This study was conducted to investigate the effects of compost application on the soil loss and physico-chemical properties at the slope land from 1990 to 1991. Lysimeters with 15% slope. 5m slope length. 2m width and 1.2m depth were constructed in 1984 and filled with sandy loam, loam, clay loam. and clay soils. Treatments were bare soil, compost(1.5ton/10a) and non-compost with soybean-barley cropping system from 1984. Losses of soil were increased with the order of sandy loam, clay, loam and clay loam. Run-off was increased with the order of sandy loam, loam, clay loam and clay, but leachate was decreased with the same order. Compost treatments decreased 33.6-44.6% of soil loss and 17.0-24.0% of run-off but increased 17.1-33.7.% of leachate as compared with the non-compost treatments. The amount of soil loss was positively correlated with the amount of run-off by Y = 12.125+0.063X (r=
경사지 토양에서 퇴비시용이 토양유실량과 토양의 이화학적 특성에 미치는 영향을 검토하기 위하여 1984년에 사양토, 양토, 식양토, 식토의 토양을 충진한 경사도 15%, 경사장 5m, 폭 2m, 길이 1.2m인 유저 Lysimeter를 설치하여 나지, 무토비, 퇴비구(1.5ton/10a)를 두고 보리-콩 작부체계로 경작해온 시험지에서 1990년과 1991년도에 조사한 2개년의 시험결과는 다음과 같다. 1. 토양유실량은 사양토, 식토, 양토, 식양토순으로 증가하였으며 물 유출량은 사양토, 양토, 식양토, 식토순으로 증가하였으나 침투수량은 이와 반대였다. 2. 퇴비 시용구와 무시용구의 토양유실량, 유출수량 및 침투수량의 증감비를 보면 토양유실량은 33.6~44.6%, 유출수량은 17.0~24.0% 감소하였고 침투수량은 17.1%~23.7% 증가하였다. 3. 토양유실량은 유출수량과 Y=-12.125 + 0.063 X(r =
