About Us

Leaders in Sustainable Soil Solutions

Microtek Organics is a South Australian certified organic fertiliser brand, built on a simple belief: healthy soil grows everything. Based in the Barossa Valley and trading since 2014, we produce microbe-rich liquid fertilisers, soil extracts, biological inputs, and pelletised worm castings trusted by home gardeners, commercial growers, hydroponic operators, and viticultural producers across Australia.

Who We Are

We're a family-owned business with over 15 years of experience across viticulture, broadacre farming, horticulture, hydroponics, and glasshouse production. Our products are certified organic under Southern Cross Certification (Cert No. 24026) and developed through years of research into vermiculture and soil biology.

We treat soil as a living, breathing system — not just a growing medium. Everything we make is designed to restore microbial diversity, improve soil structure, and reduce dependence on synthetic inputs.

Our Mission

To empower growers at every scale with biologically active, scientifically supported fertilisers that deliver real results — for the crop, the soil, and the environment.
