Min Plus was founded on the visionary efforts of Sam Catalano, a man deeply rooted in the agricultural traditions of Innisfail. With a background in sugar cane cultivation, cattle rearing, timber business, mining and quarrying, Sam established a quarry in the early 1980’s. He noticed that crops near the quarry exhibited fewer diseases, and cattle showed a preference for grazing in the area.

With curiosity and determination, Sam collaborated with the CSIRO (Commonwealth Scientific and Industrial Research Organisation) and discovered that the increased mineral content in the soil and water, derived from the volcanic rock dust was highly beneficial to plant and animal health.

Nearly five years of research led to the formulation of a revolutionary product using mineral rock dust. with CSIRO led to the formulation of a revolutionary product using mineral rock dust. A pilot plant was established to ensure consistency, and custom equipment was designed to product a viable product.

In July 1992, Sam Catalano began manufacturing and selling Min Plus locally and nationally. Under  his leadership, Min Plus became a proven and successful product.
