Abstract
Three photo-techniques were used to make backscattered electron scanning images (BESI) of the same area in a thin section of soil using a scanning electron microscope (SEM). Subsequent porosity analysis with an image analyzer (Quantimet 720) showed that different results could be obtained in a number of diameter classes while the total porosity was virtually the same, a phenomenon which may be related to beam instability of SEM. Under such conditions, one needs a dependable photo-technique in which soil constituents on a BESI micrograph can be compared with the same constituents on the display screen of SEM and Quantimet. Such a photo-technique is suggested and can be used to obtain a limited number of measurable BESI micrographs.
