SOIL COMPONENT ANALYZING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a soil component analyzing method for easily analyzing organic components in soil in a short time and evaluating the soil. SOLUTION: A wavelength group of near infrared spectrums with high correlation with a chemical analysis value of each organic component is determined from near infrared spectrums of soil with chemically analyzed values of organic components included in the soil, and it is subjected to multiple regression analysis. A working curve for calculating values of organic components is prepared and assayed from near infrared spectrum data. By associating near infrared spectrums of soil with unknown values of organic components with the working curve, the values of the organic components included in the soil is computed and calculated.
