Co-founded by Ian Rew, a horticultural specalist with over 30 years of experience in biological crop inputs, Bay Nutrients brings practical field knowledge together with science-led innovation.
Our flagship product, Flamingro™, is a certified organic biostimulant derived from sustainably sourced shrimp shells. Powered by chitin, it’s designed to activate natural plant defenses, stimulate beneficial soil microbes, and improve crop performance.
We’re committed to helping growers build healthier soils, stronger plants, and more resilient production systems – through products that are proven, practical, and grounded in biology.
In California in 1992, Ian developed a liquid chitin product after noticing the improvement of plant health in soil treated with chitin.
This product saw great success and was widely used in grape vineyards across the United States. It was found to be an excellent alternative to the chemical nematicides that were being used at that time.
Growers found that this biostimulant:
In 2010, Ian returned home to New Zealand and bought a farm near Rotorua. Later, he picked up the chitin project locally, and Rew Enterprises Ltd developed Flamingro.
This new dry product improves on the previous formulation. During development, Flamingro went through extensive and successful testing at Ag Research Hamilton and Plant and Food Research Lincoln. There are ongoing trials underway across New Zealand.
Flamingro has a significantly higher chitin content than the previous liquid formulation, and Rew Enterprises are happy to be able to offer a cost effective product for optimum plant growth and a greater, healthier root mass.
