AB Yearly inputs and transformations of above - and underground plant residues of winter wheat and spring barley were followed in "intensive" (I, mineral fertilizers only) and "organic" (0, most of nutrients applied as animal manure) crop sequences. Total amount of postharvest residues was lower in I crop system compared with that in the organic (O) one. Plant residues produced in O crop system were decomposed more rapidly both under field and laboratory conditions, than those from I crop system. Differences between Corg at the beginning and at the end of ten-weeks laboratory incubation of soils enriched by plant residues indicated that soil microflora humified more intensively a) spring barley than winter wheat residues and b) underground plant residues than straw.
