Kelpman® Specialty Fertilizer is made from the fast growing tips of the Giant Pacific Kelp Plant, known by the botanical term macrocystis integrifolia. To protect and preserve the kelp bed long-term, this species of kelp is hand harvested by divers from the cold, pristine and secluded waters of coastal British Columbia. This giant kelp is the fastest growing plant known, growing up to 3 feet per day! Harvesting takes place in late spring and again in early fall (to protect indigenous species). Only the actively growing portion of the plant-the top 2 to 4 metres-is selected.
The manufacturing process is simple and distinctive. The harvested kelp plant is brought to the processing plant where it is power-washed with fresh water. Then the kelp is liquified by a specialized cold process which mechanically reduces the plant to a potent liquid which is compatible with any commercial spray or applicator equipment. Kelpman® Liquid Kelp retains all of the kelp’s natural properties and is in no way chemically altered.
By contrast, competing liquid kelp products are dehydrated using caustic bases under high temperature and high pressure which disintegrates the kelp. Due to the aggressive processing they must endure, dehydrated kelp products are inferior in quality and performance.
