초록
휴경답에서의 휴경년한에 따른 토양의 이화학적 특성과 주요 영양분의 변화 및 잡초종의 식생 변화를 조사하였다. 휴경년한이 경과할수록 휴경답 토양의 유기물 함량이 증가하였으며 pH는 휴경후 3년까지는 변화가 없었으나 이후로는 다소 증가하였다. 토양의 양이온치환용량 및 치환성 N, K, Ca, Mg의 함량은 휴경후 3년까지는 감소하였으나 휴경년한이 길어지면서 증가하였다. 유효
Changes in physico-chemical properties and major nutrient contents were investigated in the soil of paddy fields during fallow period. Weed vegetation change in the fallow paddy fields was also examined. As the fallow period became longer, organic matter content in the paddy soil has gradually increased. Soil pH of the paddy fields has not changed until three years of fallow period and thereafter slightly increased. Cation exchange capacity of the paddy soil, and exchangeable N, K, Ca and Mg contents in the soil tended to decrease until three years of fallow period and then increase with the prolonged fallow period. As the fallow period became longer, available
