MICROELEMENT COMPOSITION OF HUMIC PEAT AND SAPROPEL PREPARATIONS
The content of trace elements (Mn, Co, Cr, Ni, Cu, Zn, As, Sr, Cd, Mo, Se) in the composition of samples of peat and sapropel selected Polessye in Gomel, and humic preparations derived from them has been determined on optical emission spectrometry with inductively coupled plasma Optima 3000 DV. The biological activity of peat and sapropel humic substances has been assessed by vigor and germination of barley and maize and rye biomass growth and corn grown by water culture. The possibility of increasing the solubility of trace elements in the preparation of humic substances on the basis of sapropel introduction of complexing extraction solution and nitrogen-containing organic bases (Trilon B, glykokol, citric acid, monoethanolamine) has been studied.
