Abstract: A water-suspensible, dry, vitamin-hormone horticultural product for promoting plant root growth comprising a combination of one or more plant growth regulators, mycorrhizae, vitamins B1 and B6, sea kelp and beneficial microbes in a carrier. In one embodiment the product is a dry powder of about 2.00 wt % indole-3-butyric acid in crystalline solid form; about 0.20 wt % thiamine mononitrate (B1) in water-soluble powder form; about 0.20 wt % pyridoxine HCl (B6) in water-soluble powder form; about 2.64 wt % Mycorrhizae in water-soluble powder form; about 1.06 wt % sea kelp extract in brown flake form; about 0.88 wt % Bacillus amyloliquefaciens in water-soluble powder form; about 0.07 wt % sodium lauryl sulfoacetate in water-soluble powder form; and about 92.35 wt % maltodextrin in water-soluble powder form.

Abstract: Cathodic protection of steel in a building or other concrete or similar structure is provided by locating an anode in a suitable location adjacent to the steel and providing an impressed current from a power supply to the anode. The anode is formed from a material which is more electro-negative than the steel so that in the event that the power supply falls below the galvanic potential therebetween, current flows under galvanic action to replace the impressed current. A diode in the circuit prevents flow of current across the power supply but allows the galvanic current when the power supply fails open circuit. An additional diode can be provided in the event the power supply fails closed circuit to prevent reverse current flow.
