Our DynaGold™ line of foliar fertilizers are classified as natural organics. Sodium glucoheptonate, which is derived from natural sugars, is used in much the same way as synthetic organics (EDTA) to form a multiple bond with the metallic ion thereby creating a stable chelate. These compounds are less apt to tie up in the soil and will stay available under adverse conditions. They enter the plant metabolism more easily and are rapidly absorbed through plant root hairs or stomata and translocate rapidly across phyloem and xylem.
