RESEARCH ON THE EFFECT OF HUMIC SUBSTANCES-BASED PREPARATIONS IN PROMOTING SOIL BIODEGRADATION PROCESSES

The paper presents an analysis of the market of fertilizers and organic additives that promote the biodegradation of herbicide residues in the soil and ensure stable growth and development of agricultural crops. The work also presents studies of the action of biostimulants based on humic substances in promoting the activation of plant defense mechanisms when combating stress in conditions unfavorable for growth.

Investigation of the Complex Formation Process of Lead (II) with Natural Macromolecular Organic Substances (Fulvic Acids) by the Solubility and Gel Chromatographic Methods

Fulvic acids are one ofthe most important ligands, governingthe geochemical cycling of metals in the environment. The objective of the work was to investigate the complex formation process between fulvic acids and Pb(II).The complex formation processwas studied by the solubility and gel chromatographic methods at pH 5.0 and 8.0.
