Potassium humate (PH) effectiveness of application for presowing seed treatment, when cultivating 21-day plants under conditions of soil contamination with 137Cs and Cd, varied depending on the soil type (soddy-podzolic, peaty, chernozem). The use of PH promoted both increase in the content in barley leaves of "a" and "b" chlorophyll (by 8 and 33% for chernozem) and carotene (by 6% for peat) and decrease in these parameters (for soddy-podzolic soil and peat) with insignificant differences in the morphological indicators of plant development. A significant reduction has been found in 137Cs specific activity in plants growing on all soil types: by 17, 25 and 73% for peat, soddy-podzolic soil and chernozem, respectively.
