Sodium Pentaborate is an inorganic boron compound used as a micronutrient boron source in specialty fertiliser formulations and as a plant micronutrient supplement to correct boron deficiency in crops such as canola, sunflower, beet, and legumes. Boron is essential for cell wall synthesis, pollen viability, and reproductive development in plants. AB Enterprises offers Sodium Pentaborate in technical grade suitable for blending into water-soluble fertiliser programs and foliar spray concentrates. It is particularly valued for its higher boron content and good water solubility compared to conventional borax, enabling efficient delivery to boron-deficient soils and crops.
