Great Land®

Great Land®

Great Land® is a patented liquid biological soil conditioner containing live, naturally occurring bacterial species from the Lactobacillus and Acetobacter genera. 

The product acts to enhances soil characteristics that enable better availability and utilization of nutrients.  Great Land® may aid in reducing the impact of disease and therefore improved yield, either through changing the soil microbiome that leads to suppressing
specific pathogens, by improving the plant’s own defences against pathogens, or both.  

Further, Great Land® can reduce the need for chemicals and fertilisers which benefits the environment and lowers input costs to farmers.

Great Land® is produced under controlled, sterile fermentation conditions to build microbe populations which are blended with energy and nutrient sources needed to sustain the microbes. Every batch is QA tested for minimum microbe population levels and viability.

Great Land® is used by conventional and organic farmers.  It is a certified input for organics in Australia and New Zealand and complies with the USDA National Organics Program (NOP).

Trials & Case Reports

Live microorganisms require special on-farm handling to ensure viability and product performance. 

  • Containers are stored out of direct sunlight and retain the vented cap, allowing microbes to respire.
  • Containers are agitated for thorough mixing prior to decanting, then diluted in preparation for prompt application.
  • Application rates, frequencies and methods vary between pastures/crops and growing conditions.  Typical rates are 10-20 litres of Great Land® per hectare (paddock area), applied two to three times per season, during active growing periods. 
  • Best results are achieved when applying late in the day to avoid ambient heat and just prior to an irrigation or rain event which flushes Great Land® into the plant root zone.
