HIGHLY CONCENTRATED BORON POWDER
The best choice for foliar applications, Solubor is formulated to dissolve quickly in liquid, leave minimal residue, and provide an economical source of boron. It has a number of different uses in agricultural markets, in addition to its long established role in farm sprays.
Solubor Technical Details -- Solubor has a minute particle size of <75 microns, which contributes to its inherent high solubility. The product’s slight buffering action helps it to maintain pH in solutions. And Solubor provides a higher concentration of boron than boric acid in solution does—up to 68.6% B2O3, compared to 56.8% maximum.
