AF Consortium

Plant growth promoting rhizobacteria

AF Consortium is a liquid consortium that contains Plant Growth Promoting Rhizobacteria (PGPR), producing strong hormone growth substances as phyto hormones stimulating rooting Phosphorus availability, plant health and biomass. AF Consortium contains microbes that are designed to thrive in a variety of stressful environmental conditions whilst giving a synergistic effect within the soil and helping to increase aeration and drainage, improving the healthy growth of the plant.

The benefits

  • Contains a carbohydrate bio stimulant to promote the initial growth of the microbial population.
  • The microbes are able to process organic materials in the soil as well as applied organic and inorganic fertilisers, making these nutrients readily available to the plant.
  • Contributes to the natural soil carbon and Nitrogen cycles.
  • Improves floc formation in the soil, increasing natural aeration and drainage.
  • Frees locked up nutrients in the soil, making them available for plant growth.
  • Contains Bacillus amyloliquefaciens.
  • Approved for use in organic systems (OF&G Organic).

Understanding the synergistic microbes in AF Consortium and their individual traits

Bacillus strains = can also solubilise soil Phosphorus, enhance Nitrogen fixation, and produce siderophores that promote its growth and supresses the growth of pathogens. Bacillus enhances stress tolerance in their plant hosts by inducing the expression of stress-response genes, phytohormones, and stress-related metabolites.

Paenibacillus = serve as efficient PGPR, which competitively colonise plant roots and can simultaneously act as bio-fertilisers and as antagonists of recognised root pathogens, such as bacteria, fungi and nematodes. They enhance plant growth by several direct and indirect mechanisms. Direct mechanisms include Phosphate solubilisation, Nitrogen fixation, degradation of environmental pollutants, and hormone production. Indirect mechanisms include controlling phtyopathogens by competing for resources such as Iron, amino acids, and sugars, as well as by producing antibiotics or lytic enzymes.

Creating AF Consortium

AF Consortium contains a synergy of select biology, with a known performance within the soil, with the security of genetic integrity of the selected microbes by obtaining specific strains from the registered ‘genetic banks’. To provide biology that best fits certain scenarios, research and field trials are carried out to determine the effects of individual microbial species and their synergistic effects within the soil.

Our fermenters are both ISO 9001 and 14001 accredited and carry out a range of quality control checks for microbial counts and contaminants. The viability of microbial products are also tested to well in excess of the pressures used in spraying equipment 60 – 700 bar to ensure ease of use.

The strains we use in this product were originally sourced from accredited repositories. As we carry out a continual programme of product improvement by selective cultivation, our strains our sent back to the German DSMZ culture collection to carry out multi locus sequencing to confirm that the microbes we are using are still the same species (selective cultivation slightly changes the genetic make-up of the microbe so this is a part of our standard quality control). Once the species has been confirmed, because of the slight genetic changes from the original, it is a assigned a new, unique strain number. This is why we can state that we use unique selected strains in our formulations.
