This study was carried out to know the substitute effect of Yacto (leaf mold compost) on popped rice hulls compost (PRHC) in Yang-jik nursery bed of Panax ginseng. PRHC was mixed with Yacto as 50:50 ratio, and 1 ~ 2% of the mixed oil cake, rice bran and urea were also added to promote decaying the mixed compost. The mixed compost made by PRHC and Yacto was showed that positive effect on the growth of ginseng seedling when it was mixed with 1% of oil cake and rice bran, and 2% of mixed oil cake. But addition to the 2% of urea in the mixture of PRHC and Yacto was not positive effect on the growth of ginseng seedling. Root yield of the mixed compost was similar to that of conventional compost by made 100% of Yacto. Therefore, the mixed compost can substitute for Yacto when PRHC and Yacto were mixed by 50:50 ratio and added 1% of oil cake and rice bran.

This study was carried out to select economical byproduct composts as the substitute for the traditional organic fertilizer, Yacto, in the cultivation of ginseng seedlings, and to investigate the application method of a selected compost. Among tested byproduct composts, popped rice hull compost was the best substitute for Yacto, while the application of domestic animal manure composts resulted in red skinned roots of ginseng seedlings. Optimal mixing ratio of the popped rice hull compost with virgin soil (fine sand) were 3~4 : 1 in bulk, showing the same root yield compared to that of conventional seedbed soil. When the popped rice hull compost was lower than $1\;{\pm}\;0.1%$ in nitrogen content, the expeller cake of oil seed was added to seedbed soil to rise nitrogen content until $1\;{\pm}\;0.1%$.

시험에 사용한 팽화왕겨퇴비는 T-N 1.173%, 질소무기화율 33.5%, C/N율 35.4로써 높은 C/N율을 가졌다. 본시험은 전북통의 토양에서 동진 1호를 재배하였으며 2년간 팽화왕겨퇴비를 시용하였다. 팽화왕겨퇴비의 시용은 유기물 및 치환성 칼륨 함량을 증가시켰으며 시용량이 증가할수록 용적밀도 및 공극률이 향상 되는 효과를 나타내었다. 토양 중 $NH_4-N$ 용출양상은 최고분얼기 이전까지는 표준시비구에서 높았다. 시비질소 흡수량은 생육초기 표준시비구에서 많았으나 성숙기에는 팽화왕겨퇴비 시용구에서 다소 많았으며, 팽화왕겨퇴비 시용구들 간을 비교해 볼 때 생육전반에 걸쳐 50% 대체구에서 흡수량이 가장 많았다. 질소 이용률은 팽화왕겨퇴비 시용구에서 전반적으로 높은 이용률을 보였다. 쌀수량은 표준시비에 비해 모든 팽화왕겨퇴비 시용구에서 낮았으나 팽화왕겨퇴비 40% 시용구에서는 표준시비와 거의 비슷한 수준의 수량을 보였다.
