The results of the research on studying the influence of drainage and long agricultural use (50 years) of peat soils on the transformation and content evolution as well as on the structure of phosphate fractions are presented. Under the influence of anthropogenic factors along with the reduced content of organic matter in soil the equity participation of organic compounds also decreases from 88 to 62% and mineral compounds specifi c weight increases. Relative reserves of mobile (from 5 to 35%), accessible (from 0.8 to 6.8%) and easily accessible (from 0.8 to 5.8%) phosphate compounds increase. As soon as the content of organic matter in soils reduces their phosphate fund becomes more 'crumbly'.
