초록
벼 2모작 재배시 보릿짚시용후 질소시용량별 토양의 이화학적 변화와 수도체의 양분흡수량, 질소이용효율을 조사하기 위하여 2년간('97~'98) 전북통에서 시험한 결과는 다음과 같다. 보릿짚시용으로 경도, 용적밀도, 고상율이 낮아졌고 공극율과 기상율이 증가하여 토양의 물리성이 개선되었다. 보릿짚시용으로 벼 재배후 토양의 pH, OM, T-C,
This experiment was carried out to investigate the effects of amount of nitrogen application with the barley straw application on the changes in soil physical and chemical properties. nutrient uptake and percentage recovery of chemical fertilizer N in the rice plant from 1997 to 1998. The soil physical properties, such as bulk density, hardness, porosity and gaseous phase were improved by barley straw application. There was also improvement or increment in the soil chemical properties, such as pH, organic matter, T-C. T-N, available
