Water‑Soluble Seaweed Extract Detailed Specifications
DONGKWANG Water‑Soluble Seaweed Extract Fertilizer is a high-quality biostimulant containing natural growth regulators (auxins, cytokinins, gibberellins), polysaccharides, amino acids, and trace minerals. Its fully water‑soluble formula ensures immediate availability for plant uptake, promoting root elongation, lateral root formation, shoot growth, and overall plant metabolism.
This product enhances stress tolerance under drought, salinity, or temperature extremes, improves nutrient uptake efficiency, and supports uniform crop growth across cereals, vegetables, fruit trees, greenhouse crops, and hydroponic systems. Additionally, it stimulates beneficial soil microbial activity and improves soil structure and water retention.
