About Us

South Australian agribusiness supplier & Eco-Ag consultants Bio-Tech Organics™, is a pioneer in biological farming methods, having commenced operations in 1990 selling fish fertilisers and humate based materials to local horticulture growers in South Australia.

Today we are providing farmers with state-of-the-art carbon-based
fertiliser products, specialist biological inputs and practical knowledge in sustainable farming systems developed by the company over 26 years.

The Virginia Biological Farming Centre sits in the hub of the northern Adelaide plains
horticulture district with some 700 hectares of greenhouse crops and many more hectares of potatoes, onions, carrots, olives, almonds, cut flowers, wine grapes, cereals and pasture, on the doorstep.

With intensive, chemically-based farming being practiced here for more than 50 years there are many problems being faced by local farmers, particularly the build-up of salinity and resistance to pesticides and fungicides by pest species, a major problem in the district. The adoption of biological farming methods is being made by many growers, with tremendous benefits to production, quality and environmental issues being achieved.



From horticulture to viticulture, broad-acre, conventional, organic, or home gardener, Bio-Tech Organics can assist those growers/farmers looking to improve their production systems.


Improvements in production, produce quality, reduced chemical inputs, soil and biological balance, less pest and disease pressure. This is the feedback we have received from many farmers over the years.


'To support progressive farmers looking to adopt a more natural (biological) approach to their farming practices by providing the knowledge, education and up to date products and programs for improved production, less reliance on chemical intervention and sustainable land management'.

our mission

" Balance is crucial to sustainable agriculture systems, however, many of the farms we survey are very much out-of-balance, particularly in the area of soil fertility and biology, a forerunner to unsustainable practices and less than optimum production. Soil humus (carbon) levels for example, are crucial to a viable and productive farm, and yet most of the soils we have tested over the years are extremely low in soil carbon. Humus management is a vital component to the sustainability of agricultural soils, maximizing crop water-use efficiency and ecosystems conservation. Colloidal humus is possibly the most overlooked element in soil fertility management and crop production systems, due mainly to the emphasis on synthetic nutrient inputs, particularly NPK. Our mission is to correct this imbalance for the benefit of the environment, the farmer and the consumer".
