Features : The beneficial effects of THUNDER can be grouped according to effects on physical, chemical and microbiological properties of the plant. Humic (humate) materials have been found to greatly promote root initiation in cuttings and a proliferation of root systems through auxin activity. Humic substances are capable of chelating and retaining soil nutrients in an exchangeable form to be made available for plant growth as required. The very high ion exchange capacities of humates bring about better utilization fertilizers by making nutrients available in the root zones. THUNDER buffers high and low pH to bring soil into balance.
