The analysis of the role of humus and its group structure in formation of yield of barley grain is given. Correlation dependencies between the productivity of barley and the indices showing qualitative structure of humus (the content of mobile and labile forms of humus substances) are presented. The interrelation of the yield of investigated crop with group structure of organic-mineral particles of the 1-st and 2-nd groups sized less than 0,01 mm (according to A.F.Tjulin) is shown
