SummaryQingdao Haidelong Biotechnology Co., Ltd. is identified as a China-based manufacturer established in 2008, with 102 employees, five production lines, a 600 m² manufacturing plant, and products including seaweed extract, water-soluble fertilizer, microbial fertilizer, chelate trace fertilizer, amino acid, and potassium humate.
