    Details

    Chitosan Oligosaccharide is a high-activity bioactive polymer derived from chitin deacetylation. It functions as a natural plant growth promoter, improving root vigor, stimulating nutrient uptake, and enhancing metabolic efficiency. Chitosan oligosaccharides also induce plant stress response mechanisms, helping crops tolerate drought, salinity, and other environmental stresses. Its high solubility and biocompatibility allow it to be applied directly or incorporated into liquid fertilizers, providing a safe, efficient, and sustainable solution for crop nutrition and quality improvement.
