Improved Dispersion and Wetting Characteristics


Foliar application of Boron compounds is an effective method for maintaining adequate B levels in crops or for correcting deficiencies.  Several Boron-containing products are commercially available, but basically there are only two forms of B suitable for use on crops: Boric Acid and Sodium Borate.  Boric Acid is the form in which Boron is directly absorbed and utilized by plant foliage.  Borate compounds must be hydrolyzed to Boric Acid before they can be effective.

Sodium Borate is not the sodium salt of Boric Acid, but is a term used to describe a group of materials derived from Borax: Fertilizer Borate, Solubor, Boro-Spray, and Borax itself.  These products differ in the amount of Boron, Sodium, and water that they contain.
