The accurate analysis of soil pore structures in soil thin sections depends on achieving sufficient contrast between soil pores and minerals. The objective of this research was to develop a method that requires a minimum number of crossed polarizer images to distinguish minerals from pores in soil thin sections. Five undisturbed soil samples were taken from each of the three soils used in the experiment. One thin section was made from each sample. Images of the thin sections were captured with a digital video camera through a microscope at X3.2 and saved for later analysis. Two crossed polarizer images at 0 and 45 degrees combined with a plane light image could distinguish more than 90% of the minerals. The combination of three crossed polarizer images at 0, 30, and 60 degrees was more efficient than Ismail's method, which used six crossed polarizer images
