Zincubor

Perfect combination of boron and zinc

2:1 zinc-to-boron ratio

A perfect blend of zinc and boron

Boron and zinc deficiency in soils go hand-in-hand. That’s why U.S. Borax developed Zincubor®—the perfect balance of both zinc and boron to adequately supply your crops with the nutrition they need.

Application and benefits

Because zinc and boron deficiency are widespread around the world, a product with both nutrients is a good fit in many regions. Zincubor brings these two important micronutrients together in one product. Perfectly formulated with a 2:1 zinc-to-boron ratio that exactly meets most crop demands.
 
Zincubor is produced at U.S. Borax’s California facility in the United States. It is a synthetic fertilizer material made out of high-quality raw materials from our world-class boron and zinc sources. Zincubor is a consistent product with no added impurities and no fillers.
  • Micronutrient coating: Zincubor is designed to coat granular/compacted fertilizers giving flexibility on the micronutrient rate and assuring an even distribution in the field. U.S. Borax recommends the use of a binder material during the coating process.
  • Compound fertilizer: In certain countries, Zincubor can be used as a raw material (intermediate ingredient) to produce enriched/fortified compound fertilizers.

Technical Details
