Zinc is one of the eight essential micronutrients needed by all plants in small amounts, yet some plants are poor accumulators and transporters of Zinc, so a foliar application of Zinc is recommended for many crops.
Carbon Amino ZnTM should be your foliar Zinc of choice because of the added benefit of Catalyst TechnologyTM, which combines organic carbon materials and amino acids with organic and inorganic nutrients and forms a layer of protection around the Nano-particle Zinc, allowing it to effortlessly enter the leaf and/or root.
