Soluble phenolic compounds, total nitrogen, and ammonium nitrogen in the litter horizons of undisturbed spruce forests in the central forest reserve

Description
Summary:Litter samples from peat podzolic (Stagnic Podzoluvisol) and soddy gley (Mollic Gleysol) soils differing in their chemical and physicochemical properties, geochemical conditions, and the character of soil microbial complexes were analyzed. The sampling was performed three times during the growing season: in May, August, and October. The contents of ammonium ions, soluble phenolic compounds, and flavans were determined in all the samples. The litters of the two soils differed in the contents of both ammonium ions and phenolic compounds. Distinct seasonal dynamics of ammonium and phenolic compounds were registered in the litter of the peat podzolic soil. The high negative correlation between the contents of ammonium ions and phenolic compounds was found for the samples collected in May.
