Boron Deficiency in Europe

European growers face boron-depleted soils, especially given the demands of widespread crops such as rapeseed, sugar beet, sunflowers, wine grapes, olives, apples, and forestry. Specialized refined boron can help, and offers a variety of application methods to meet growers’ needs.

In this region, growers especially need a refined boron product that can deliver improved crop quality and yield. Climate, weather, and soil conditions vary widely across Europe, as do crops and specific crop needs, from oil seed rape in northern Europe to olive trees in the Mediterranean area. Sandy soils with acidic pH are extremely susceptible to be boron deficiency in Northern Europe. In the south, high calcareous soils also affect the availability of boron. Refined borates are also useful for improving frost-resistance of crops like oil seed rape.

Improve Soil Conditions with Boron Supplementation

Our refinement process guarantees optimally sized, low-dust granules, perfect for mixing with other nutrients or fertilizers for optimal return on investment (ROI). Because our boron is mined as sodium borates rather than sodium calcium borates, it is naturally more water-soluble—and our refinement process improves solubility even farther. Our refined boron products are free from contaminants and are available for soil or foliar application as well as in a variety of fertilizer mixes.

U.S Borax products, whether purchased alone or as part of co-branded fertilizer mixes, deliver the most optimally available, completely water-soluble refined boron per metric ton, increasing ROI and providing peace of mind for growers and distributors who demand reliability and safety.

U.S. Borax Solubor® DF is tested for compatibility with many fungicides and fertilizers, so it can be mixed and used without problems.

Liquid formulations are particularly popular in these countries for foliar applications and can be used to coat finished solid fertilizers, to provided refined boron through irrigation or hydroponics, or the formulation of high-performance liquid fertilizers. U.S. Borax Solubor Flow and Liquibor® provide high-quality, refined boron Solubor Flow is produced without the use of organic solvents. These products maintain suspension well, separating only slightly upon resting—simply shake or stir to re-suspend. Crystals do not form through sedimentation.
