Effects of mechanically activated clinoptilolite zeolite on growth of perennial leguminous grasses

The results of research on the influence of clinoptilolite zeolite, phosphorus-zeolite, and zeoliteorganic fertilizers on seed germination and growth of perennial legume grasses by laboratory phytotesting in grey forest soil are presented. It was found that as a result of filling the interpolymer complex with clinoptilolite zeolite, hydrogen bonds are formed between carbonyl groups of polyacrylamide and silanol groups of the mineral. The important role of the size factor in the influence of fertilizer on plant growth has been established. It is shown that mechanically activated clinoptilolite-rich rock (mechanical energy dose 2.4 kJ $\cdot$ g$^{-1}$) and the polyvinyl alcohol/polyacrylamide interpolymer complex resulting from mixing equivolume aqueous solutions with concentrations of 4 g $\cdot$ dL$^{-1}$, filled with 0.4 wt% mechanically activated clinoptilolite-rich rock (mechanical energy dose 3.8 kJ $\cdot$ g$^{-1}$), have a positive effect on germination and stem length of perennial legume grasses of meadow clover, eastern galega, and sand sainfoin in dark grey forest soil.
