Commencing the manufacture of its organic fertilizers in 1988 from a small factory at Kanmantoo in the Adelaide Hills of South Australia, Neutrog has since grown to become the largest manufacturer of its kind in Australia. It deals in the manufacturing of various biological fertilizers.

As a company, Neutrog is only at the beginning of its biological evolution, but they are already manufacturing products that are more microbiologically diverse, making them more robust and adaptable, and more tolerant to drought, heat and frost.
