Boron and U.S. Borax

Boron is a naturally occurring mineral. But the refinement and quality control U.S. Borax provides is necessary so the boron can:
  • Mix well with other nutrients
  • Dissolve completely in liquid applications
  • Have uniform application
  • Provide maximum availability to crops
Subpar products might cost less up front, but high-quality, refined boron is cost competitive when evaluated on a price-per-useable-kilogram basis.

The boron found in our California deposit is primarily calcium-free sodium borate and the site is one of the cleanest sources of boron in the world.
Boron is a micronutrient that is essential to plant growth. Adequate boron is necessary for proper absorption of macronutrients.

Although boron is a naturally occurring element, boron deficiencies are common. Overfarming, extremely hot or cold conditions, drought, an overabundance of rainfall or irrigation, sandy soils—all these factors can reduce the amount of boron available to crops.

Refined boron from U.S. Borax is the right product to address boron deficiency, whatever the crop and region. Our commitment to refinement and quality control provides a fertilizer that mixes well with other nutrients, dissolving completely in liquid applications and creating a uniform, low-dust mix in granular formats. As a result, growers can achieve a more effective application for maximum nutrient availability without concern about the contamination or uneven application rates that are often seen with unrefined or under-refined minerals. Plus, U.S. Borax has a wealth of expert advice, scientific studies, and regional resources to help distributors, agronomists, and growers achieve great results.
Boron deficiency is the second most common micronutrient deficiency problem worldwide. Learn more about boron deficiency symptoms.

U.S. Borax, part of Rio Tinto, is a global leader in the supply and science of borates—naturally-occurring minerals containing boron and other elements. We are 1,000 people serving 650 customers with more than 1,800 delivery locations globally.
