Boron SolUbility

Refined products with high solubility offer more available boron per application than do unrefined borates that fail to fully dissolve. Borate minerals that are only partially soluble are more difficult for plants to use, provide patchy coverage, and often leave insoluble contaminants behind in the field.

Research shows that not all boron sources are equal in their ability to provide plants with soluble boron throughout the season. In the tests below, all samples were of similar particle size.

Leaching occurs when soil loses essential nutrients due to excessive rain. You may have heard that a refined, higher soluble boron is more prone to leaching than a unrefined boron. Boron, no matter it's source, is water soluble. Because boron is a neutrally charged ion, it floats in ecosystems until it finds a substance to which it can cling.

Depending on soil type, an application of 4.4 pounds of boron/acre (4.93 kg/ha) can leach out of the soil within as little as 6 months.

Controlled release boron fertilizers will help you maintain the proper balance of micronutrients during wet and dry weather. They are widely available, but the rate at which they release can vary. The ideal release should be slow enough to protect against leaching and toxicity, but fast enough to supply essential nutrients to plants when needed.
