About Disodium Octaborate Tetrahydrate

Disodium octaborate tetrahydrate (DOT) is one of the most water-soluble and boron-dense borate salts available, making it a preferred boron micronutrient source for precision agriculture. Boron is an essential micronutrient for plant growth — critical for cell wall development, pollen germination, fruit set, and sugar transport. DOT dissolves readily in water at ambient temperatures, enabling easy incorporation into liquid fertilizer systems, fertigation programs, and foliar spray solutions without heating or special handling. Its near-neutral pH (7.0–8.5) makes it compatible with a wide range of nutrient solution formulations. DOT is also used as a wood preservative, fire retardant component, and in industrial applications requiring a concentrated, highly soluble boron source.

Applications

  • Boron micronutrient in liquid and dry fertilizer blends
  • Foliar boron spray for fruits, nuts, vegetables, and row crops
  • Fertigation and drip irrigation boron supplementation
  • Correction of boron deficiency in high-yield crop systems
  • Wood preservative and fire retardant formulations
