Abstract
Participation of phosphate ions in specific (donor-acceptor) interactions with humic acids in forest soils was found to change the structure and properties of the acids. Chelate entities containing aluminum and iron atoms were detected in humic acids molecules occurring in overphosphatized soils. The behavior of phosphorus-modified humic acids in polar media is discussed.
