In the study the results of researches of change of organic carbon pools (active, slow and passive) in agrodark bleached soils with crops of different phytomeliorants (timothy, rump, clover, alfalfa) and their mixtures (timothy+clover, rump+ alfal-fa) are given. The tendency to the accumulation of Corg and stocks Corg in the horizon PU on experimental options with crops of phytomeliorants was found out. The greatest accu- mulation of Corg was recorded in the crops of alfalfa and grass mixtures: rump+alfalfa, timothy+clover. The share of labile organic matter extracted with neutral pyrophosphate extract of the horizon was from 31.9 to 36.6 % from Corg. Higher rates of C lab were typical for the variants with the seeding of clover and alfalfa. The close link between the General content of the Corg and Clab was determined. The correlation coefficient wasIt was established that the pool of transformed organic matter (Ctrans) increased on all variants of the experiment with the crops of phytomeliorants compared to the control. In the horizon PU agrodark bleached soils with crops of different phytomeliorants different proportions of active, slow and pas- sive pools of organic matter were determined. The greatest number of Corg was in passive pool (up to 66 %), the share of active pool accounted to 37 %, and slow to 10 %. In autumn the increase in organic carbon of active and slow pools on the variants with crop mixtures: rump+alfalfa, timothy+clover and rump was observed. On experimental options with crops of alfalfa, clover and Timothy the regularity to lower Corg active pool and growth of slow was clearly expressed. The differ- ences in the distribution of Corg, active, slow and passive pools in the horizon PU agrodark bleached soils with crops of phytomeliorants testified to the differences in the intensity of flow transformation processes of soil organic matter.
