This study was 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. 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.
