Аннотация:The methods and results of tomographic soil studies are discussed. A brief history of the develop
ment of the tomographic method and its application in soil science are described, and the major results
obtained with the use of this method are outlined. An experience of the application of Xray microtomogra
phy for studying the structure of undisturbed samples of some Russian soils is also considered. Threedimen
sional images of soil aggregates and soil pore space with a resolution of 15.8 μm have been obtained for the
upper horizons of gray forest and soddypodzolic soils. On the basis of these data, the merits and demerits of
the tomographic method in comparison with the traditional method for studying soil pedality and pore space
in thin sections are discussed. Certain advantages of the tomographic method provide good possibilities to
study soil processes at a qualitatively new level. Priority directions of the development of tomographic studies
in soil science are outlined.
