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 improve plant health and productivity by increasing the availability and uptake of soil-bound nutrients.  Great Land® enhances plant growth and plant defences against environmental stress, pests and pathogens.  Further, Great Land® reduces 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 crops and growing conditions.  Typical rates are 40-80 litres of Great Land® per hectare of treated 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.

Further information is provided in the Storage, Handling & Application document.  Crop specific details can be obtained from Terragen or our distribution partners.
