What it is

Biomin Zinc is part of the Biomin range of amino acid chelated minerals supplied through Roots, Shoots and Fruits. The nitrogen on the label comes from the amino acid chelate. It dissolves in water for spraying or irrigation.

What it does

• Zinc is needed to make auxin, the growth hormone, and is a cofactor for many enzymes.
• Deficiency shows as small leaves, short internodes and bunched shoot tips. High soil phosphorus is the usual cause.
• Chelated zinc stays in solution so it can be sprayed on leaves, which is the fastest way to correct a deficiency.

Analysis

• Zinc (Zn) 20.0 percent w/w
• Nitrogen (N) 6.2 percent w/w, as amino acid

How to use

• Dissolve in water and spray for even distribution.
• Zinc has a narrow margin between enough and too much: apply from a soil or leaf test and do not exceed the rate.
