U.S. Borax: Refined, quality borates

:: Wednesday, May 1, 2024 :: Posted By Roger Gunning
Investing in premium fertilizers can helps ensure a bountiful harvest. If you’re looking for both the best value and highest quality fertilizer for your fields, U.S. Borax’s unique refining process produces a superior boron over the competition. Although opting for unrefined borates may seem like a cost savings, by the end of the season, you will find yourself purchasing more and applying more borates to achieve the same results. 

Unrefined borates include impurities, including arsenic and other heavy metals, that you don’t want in your crops. Refined borates from U.S. Borax have little to no impurities—ensuring the fertilizer you put on your field is 100% soluble boron.

What sets U.S. Borax apart?

The answer is simple: Our refining process. While other products on the market have just been filtered, calcinated and conveyed, our borates go through a rigorous, six-step process:

1.    Dissolving 
2.    Settling
3.    Crystallizing
4.    Filtering
5.    Drying
6.    Conveying

This refining process doesn’t stops after step six. Rigorous research and testing to improve our products ensure we are produce high quality borate fertilizers. We conduct field trials around the globe with respected academic and agriculture institutions. The differing soil and weather conditions allows us to make targeted recommendations depending on your region and crop. 

Refin​ement improves application

Keeping your fertilizer applicator moving in the field, saves you time and money. For this, you need consistency. For soil application, Granubor®’s uniform particle size means simple blending with NPK fertilizers and even distribution in spreaders. For foliar application, Solubor® easily mixes in your foliar spray with little to no residue—keeping nozzles clean. Better quality borates means less time mixing and maintaining..
