Abstract
本文之目的乃探討土壤樣本乾燥後，對於磷、鉀有效指數之影響，與土壤性質、作物收量以及磷、鉀吸收量之關係；同時并探討其抑制方法。經選用20種本省主要土壤之樣本，予以不同乾燥處理後，分別用兩種磷、鉀速測法加以測定，所得結果摘要如下： The aim of this study was to find out the effect of drying on the soil PK and its relation to dry matter content as well as PK-uptake of rice seedlings. The control of PK-releasel/fixation on drying by addition of chemicals was also involved.
