摘要

New biostimulant compositions contain a natural mineral having ion exchange and sorption properties and active plant matter. Biostimulant comprises: (a) natural minerals with ion exchange and sorption properties selected from a clinoptilolite and helandite zeolite (containing at least 92 wt.% clinoptilolite) and/or a montmorillonite clay (containing at least 92 wt.% montmorillonite); and (b) plant matter selected from cereals, cereal waste, higher herbaceous plants, marine algae and higher fungi.
