This work delves into the process of phenolic oxidation products rdistribution in Nitisols Ferralic and Humic Cambisols, which were modified by (14C) introduced tea biomass. Metabolites derived from tea biomass were found to interact with humic and fulvic acids and form covalent bonds with them. The study of quantitative aspects of the inclusion of phenolic substances in the chemical composition of humic and fulvic acids reveals that humic acids incorporate a significantly greater amount of the radioactive tracer (14C) compared to fulvic acids. By applying the formula derived by us (D... = 1,45 Hz/6,5-pH) it becomes feasible to determine the soil microliming dosage required to expedite the processes of mineralization and humification of tea plant manure and other residues rich in polyphenolic substances. Furthermore, it is recommended to apply manganese-based microfertilizers to the soil prior to pruning tea bushes. These agrochemical measures are crucial in optimizing the mineralization of phenolic substances, neutralizing their toxic effects, enhancing the intensity of the humification process, and ultimately increasing soil fertility.
