Boron Deficiency in North America

Canada and the United States comprise vast swaths of renowned farmland. From the corn fields of Iowa to the apple orchards of Ontario, boron plays an important role in the health of North American agriculture.

Recent unpredictable weather patterns, resulting in drought or flooding, have only compounded the need for additional nutrients, and boron supplementation in the region. With aggressive profit margins and rising farming costs, growers’ hard-earned dollars must also be carefully allocated. As North American growers work to feed the region (and much of the world, through exports), they need nutrient products that meet rigorous quality and certification standards and deliver the most available boron per pound—for optimal crop health and return on investment (ROI).
​U.S. Borax boron, mined and refined in California, has been providing reliable, high-quality boron to regional growers and fertilizer distributors for more than 50 years. With the highest percentage of available, water-soluble boron of any product and a refinement process that guarantees optimally sized, low-dust granules, our agricultural products meet the strictest standards and provide the best available ROI. Our Early Fill program further helps many North American customers further increase ROI through discounts for advance ordering. Our refined boron products are available in granular or powder (for use in liquid formulations) form, for soil or foliar application as well as in a variety of fertilizer mixes.

Boron Deficiency in the Region

Western United States and Canada (West of the Rocky Mountains)
Growers in this region consistently deal with challenging weather conditions. As a result, boron deficiencies are common, especially in the rainy Pacific Northwest. Drought in California in recent years has also presented issues.

Eastern United States and Canada (East of the Rocky Mountains)
East of the Rocky Mountains, boron deficiency is a common issue. High-yield growers understand the importance of boron for sufficient crop quality and production.

University researchers have found that adding refined boron can increase corn yields by 13 bushels per acre (13.98 kg/ha) and increase soybean yields by 2 to 47 bushels per acre (2.15-50.57 kg/ha).
