Questions to Ask When Buying Boron

The best way to measure boron supplement value is to look beyond the initial price point. Low-quality, unrefined products can quickly eat up any cost savings by being ineffective—or actually creating new problems. When evaluating products, ask about the real value of the borate you’re buying:
  • How much useable, water-soluble boron does the product contain?
  • Has the product been refined to remove contaminants such as arsenic, lithium, and aluminum?
  • Does the product support multiple types of application?
  • What is the product’s bulk density?
  • Can the product make boron available throughout the growing season? 
  • Is the product durable (eg, crush resistant during transport)?
  • What is the typical particle size (for granulated boron products)? 
  • What is the price per useable measure of boron?
