PROCESS FOR THE PREPARATION OF VERMYSTYM-K BIOSTIMULANT

摘要

A process for preparation of biostimulant comprises the use of hydrodynamic cavitation for the extraction of humic acids, macro- and microelements from biohumus. After the filtration the preparation is neutralized by solutions of phosphorus, nitric or sulphuric acid. Depending on the function of biostimulant a necessary quantity of microelements in chelating form for the purpose function is introduced.
