It is identified as a manufacturer and processor focused on seaweed fertilizers, organic fertilizers, NPK fertilizers, fertilizer equipment, and related products. The supplier reports more than 10 production lines, a 260,000 m² manufacturing plant, annual seaweed extract and finished-product output of 600,000 tons, and export markets in South America, Europe, and North America. Its agronomist team provides fertilizer solutions and crop-protection advice, while reported certifications include ISO 9001, ISO 14001, ISO 45001, and ECOCERT organic-input certification.
