Description
Summary:Characteristics of the phosphate regime of forest sod-podzolic soil is presented. It is shown that the organic phosphorus content sharply decreases down the profile starting from the podzolic horizon. The maximum content of mineral phosphates determined by the method of Sanders and Williams was found in forest litter and in the transitional eluvial horizon (A 2 B) and amounted to 860 and 720 mg/kg. Iron phosphates prevail in the composition of mineral phosphates and, depending on the depth of the horizon, they are 48.8–63.2% of the sum of fractions. The shares of mobile and available to plants alkali metal phosphates and various basic phosphates are 2.9–10.1 and 10.0–14.9%, respectively.
