BioAg - Better Soil . Better Crops. Better Stock.


BioAg soil and composting nutrient and liquid microbial cultures provide an immediate and ongoing supply of  'biologically active' nutrients directly to plants, as well as stimulating microbial activity in the soil. The end result is improved health and vigour in your soils, crops, pastures and livestock.                 

BioAg products are manufactured from a range of natural and organic ingredients that not only provide a rich source of plant-available nutrients directly to crops, but help to rejuvenate soil fertility by increasing microbial mass and diversity.

With the prospect of further increases in fuel and fertiliser costs along with a surging global demand for safe, healthy and residue-free food, BioAg products and programmes offer an effective, cost-efficient alternative.

BioAg liquid cultures are the revolutionary way of delivering essential nutrients and metabolites directly to pastures and crops, ready for immediate uptake, composting organic manures as well as stimulating microbial activity in the soil.

Each formulation is based upon a proprietary fermented microbial culture that contains a rich source of vitamins, minerals, proteins, enzymes, amino acids, carbohydrates, dormant organisms and nutrients. BioAg liquid nutrients are applied using conventional spray systems.

These cultures are also used to balance microbial cultures of slurry lagoons, increasing aerobic activity, reducing surface crust and hydrogen sulphide release  as well as improving slurry fertiliser value.

The end result is improved crop and pasture establishment, plant vigour, yields and quality.

BioAg products are manufactured from a range of natural and organic ingredients that not only provide a rich source of plant-available nutrients directly to crops, but help to rejuvenate soil fertility by increasing microbial mass and diversity.
