This study was conducted to find out the coefficient relationships between intensity values of image processing and biological/physical parameters of soil in greenhouses. Soil image were obtained by an image processing system consisting of a personal computer, image processing, and image analysis. Image processing data of the soil samples were analyzed by the method of regression analysis. The results are as follows. For detecting soil density of unbroken soil, samples, the highest conrrelation coefficients of 0.82 and 0.84, respectively were obtained for R-value and S-value among image processing data of while it was 0.97 for G-value. Considering the relationship between biological characteristics and image processing data of soil in greenhouse, the correlation was found generally low. For Ph of broken soil sample, the correlationcoefficients were found 0.87,0.85, and 0.94 respectively.
