초록
옥수수 수량(收量)과 토양(土壤)의 화학적특성(化學的特性)과의 상관관계(相關關係)를 검토(檢討)하여 옥수수 재배지토양(栽培地土壤)의 토양화학성(土壤化學性) 개량(改良) 기준(基準)을 설정(設定)할 목적(目的)으로 16개(個) 옥수수 시범재배포장(示範栽培圃場)을 대상(對象)으로 조사(調査)한 결과(結果)를 요약(要約)하면 다음과 같다. 1. 옥수수 수량(收量)과 토양화학성(土壤化學性)과의 상관관계(相關關係)에서
Correlation study was conducted to establish the optimum test level of soil improvement for good growth of corn from the relationships between the corn yield and soil chemical properties in 16 farmers' demonstration fields. Significant positive correlations between the corn yield and soil chemical properties ; pH, available phosphorus, exchangeable potassium, calcium, magnesium, cation exchange capacity. available silica, and base saturation percentage were showed but organic matter and nitrogen content were not. The proper nutrient contents in soil for expecting corn yield, 1.000kg/10a could be estimated as pH 5.6, available phosphorus 327ppm, exchangeable potassium 0.39me/100g, exchangeable calcium 5.5me/100g, exchangeable magnesium 1.3me/100g, cation exchange capacity 11.5me/100g, available silica 116ppm, base saturation percentage 58 from the relationships between the corn yield and soil chemical properties. Exchangeable aluminium were negatively correlated with not only corn yield but also pH, available phosphorus, exchangeable potassium and exchangeable calcium.
