Abstract
This study was conducted to evaluate the boron phyto-toxicity on soybean grown on the potted soil amended with 20% by weight of fly ash with high and medium boron contents Of two years experiment, the first year experiment observed the direct effect and the 2nd year experiment the residual effect. Soybean growth and yield were normal with incorporation of 20% fly ash with normol B content. With high B flyash, however, the performance of soybean was poor due to B toxicity. Therefore, it is suggested that in determining the application rate of flyash, B content should be taken in account.
석탄회중의 B성분의 식물독성을 검토하기 위하여 B함량이 다른 석탄회를 작토중의 20% 해당량을 토양에 시용하고 콩을 재배하여 1년차 비효 및 2년차 잔효시험으로 수행하였다 B함량이 높은 석탄회는 20% 시용구에서 콩의 생육이 극히 불량하였으며 수량도 거의 전무상태이었으나 B함량이 보통인 석탄회의 시용으로 생육과 수량이 대조에 비해 양호하여 석탄회 다량시용시 석탄회중의 B함량의 검토가 요구되었다.
