How do we supplement zinc?

Zinc and other Micronutrients are present in KNF Minerals, also called diluted seawater. Seawater is typically applied as a soil drench at 1:30~1:20, or if you are using sea salt you can reconstitute it to a 1:30 dilution by mixing 1g per liter of water. The drench rate is 100gal/acre in deficient soils. This can also be combined with other KNF Foods made from fermented plant material that are known to be high in zinc.
