BLU-MIN 10% Lignin Zinc provides the same agronomic functions as liquid zinc sulfate. It contains 10% zinc, as zinc sulfate, complexed with lignin. It is 100% water-soluble and has extremely low levels of impurities.

Lignin acts as a mild buffer, a wetting agent and a spreading/sticking agent. Its primary usage is as a direct foliar application (sprayed directly on the plant rather than on the soil) on such perennial crops as apples and pears.  

BLU-MIN 10% Lignin Zinc is available FOB our Moxee, WA facility in bulk and pallets of 36 X 5 gallon buckets.
