Influences of various soil chemical properties on the algae growth (Chl-a concentration) at the paddy field were statistically analyzed using soil and water samples collected from 2016 to 2018 in June. As a result of correlation analysis between soil chemical properties and Chl-a concentration, significantly positive relationships were observed in pH, EC and SiO₂. To identify the key soil chemistry variables and predict Chl-a concentration, factor analysis was done and three principal components (PCs) with eigenvalues > 1 were found, which accounting for 60.9% of the original variance. The PC1 included Mg<SUP>2+</SUP>, Ca<SUP>2+</SUP> and Avali.-P. The PC2 included pH, Na<SUP>+</SUP>, K<SUP>+</SUP>, and Avail.-SiO₂. PC3 included OM and T-N. According to the result of linear regression analysis based on the factors by factor analysis, the total explanation amount was 18.0% and only PC3 had an significant influence on the decrease of Chl-a concentration. These result will be used for soil management to prevent algae blooms at rice paddy field.
