About Boric Acid
Boric Acid Fertilizer for Boron Supplementation
Boric Acid is a water-soluble boron fertilizer with 17-18% boron, formulated to correct boron deficiencies in crops like cotton, peanuts, and grapes. Boron supports pollen viability, fruit set, and cell wall strength, leading to 10-15% yield gains and improved produce quality.
Suitable for foliar or fertigation use, it dissolves easily for uniform application. Benefits include better pollination, reduced hollow heart in peanuts, and enhanced stress tolerance, supporting sustainable farming in boron-poor soils.
