Nutri-Life 4/20

A task specific, freeze-dried blend of bacterial strains and beneficial fungi.

The Nutri-Life 4/20 microbes include effective cellulose digesters, general decomposers, mineral solubilisers, co-factor species, very effective free-living nitrogen fixers (Azotobacter species), phosphorus solubilisers and predatory fungi. These species are very hardy and flourish in a wide range of soil types and are also used in hydroponic systems to enhance nutrient uptake.


  • Increased nutrient uptake.
  • Improved soil structure.
  • More rapid decomposition.
  • Nitrogen fixation.
  • Increased phosphorus availability.
  • Improved organic carbon conversion rate.
  • Soil detoxification.
  • Release of locked up trace elements.
  • Improvement of the ratio between desired and undesirable micro-organisms.
  • No withholding period.
  • Biological Farmers of Australia (B.F.A.) Registered Product 456AI.

Application Rates

Brewed Concentrate: Nutri-Life 4/20 must be brewed for 24-48 hours in warm, well oxygenated, clean water. Maintaining adequate aeration and keeping the brew in the correct temperature range are vital to achieve maximum benefit from the subsequent applications of the product.

20 litres: Heat water to between 25-30oC. Add 25 grams of Nutri-Life 4/20 and 200 mL of LMF™ (Liquid Microbe Food).

200 litres: Heat water to between 25-30oC. Add 250 grams of Nutri-Life 4/20 and 2 L of LMF™ (Liquid Microbe Food).

1000 litres: Heat water to between 25-30oC. Add 1.25 Kg of Nutri-Life 4/20 and 10 L of LMF™ (Liquid Microbe Food).

Life-Force® Blend: 40 litres of brewed concentrate per tonne.

Soil: 20 - 100 litres of brewed concentrate per hectare.

Foliar: 100 litres of brewed concentrate per tonne of seed.

Seed Treatment: 12 litres of brewed concentrate per tonne of seed.

Hydroponics: 20 litres of brewed, screened concentrate per 1000 litres of nutrient solution. Treat every 4 weeks for maximum results.

Storage & Handling

Contains live organisms. Do not mix with biocides. Store in cool, dry place away from sunlight. Shelf-life – 1 year from manufacture date (unopened). May be stored in a refrigerator after opening for up to 3 months. However, contamination may occur once opened. Gloves and breathing mask should be worn at all times when handling microbial products.


  • Can also be used to clean up waterways, dams and irrigation sources.
  • Can improve septic tank performance.
  • Is effective when used for leaf, soil and hydroponic applications.
  • Nutri-Life 4/20 is supplied as dry kelp granules containing the microorganisms in a dormant state.
  • Has proven effective as a side dressing.
  • This product requires "brewing" with LMF™ (Liquid Microbe Food) to activate and multiply the species prior to application.
  • Warmth (30oC) and oxygen (>5ppm) can help to achieve maximum results.
  • Brewing equipment must be cleaned prior to use. To clean equipment, use Nutri-Gen (hydrogen peroxide) diluted to 1%. Leave standing for fifteen minutes, then drain and flush with clean water.

Nutri-Life 4/20 is not compatible with biocidal chemicals
