Abstract
To compare various methods for available soil P test, in terms of correlation between crop yield and amounts of available soil P, a pot experiment was conducted with soybean as test plant using four upland soils differing in phosphorus status. The results are summarized as following. 1. There was highly significant correlation between grain yield and amount of P uptake observed at the floral differentiation stage. Highly significant correlations were also observed between grain yield and available soil P of different methods, and between the amount of P uptake and available soil P. The consistency of correlations between soil P and plant parameters was Olsen
우리나라 전토양(田土壤) 분석(分析)에 적합(適合)한 토양유효인산분석법을 밝히고자 4개토양(個土壤)을 가지고 토관(土管)에서 대두(大豆)를 재배(栽培)하여 수량(收量) 및 식물체중(植物體中) 인산흡수량(燐酸吸收量)과 토양중(土壤中) 유효인산(有效燐酸) 흡수량(吸收量)과의 관계(關係)를 검토(檢討)한 결과(結果)는 다음과 같다. 1. 대두수량(大豆收量)은 화아분화기(花芽分化期) 식물체중(植物體中) 인산흡수량(燐酸吸收量)과 높은 상관(相關)이 있었고 식물체중(植物體中) 인산흡수량(燐酸吸收量)은 각방법별(各方法別) 토양유효인산(土壤有效燐酸)과 높은 상관관계(相關關係)가 있었으며 그 상관도(相關度)는 Olsen P
