🌊 Seaweed SOP-Based Compound Fertilizer (13-10-22 S)
Low-chloride, high-potassium compound fertilizer enriched with alginic acid and fucoidan from seaweed. Formulated for chloride-sensitive crops such as tobacco, grape, tea and citrus.
Low-Cl, High-K Formula
Chloride ≤ 2% with sulphate-of-potash supply protects chloride-sensitive crops while delivering ≥22% K₂O plus valuable secondary sulphur.
Alginic Acid Improves Soil
Promotes soil aggregate formation, improves water & nutrient retention, and builds a healthier rhizosphere that suppresses soil-borne disease.
Fucoidan Chelates Micronutrients
Chelates Fe, Zn, Mn in the root zone, raising micronutrient availability and preventing deficiency symptoms.
Better Fruit Quality
SOP combined with seaweed actives raises sugar content (Brix), colouring and flavour while extending shelf life.
