Éra N-Fix:
Atmospheric Nitrogen Fixation / Antagonist Activity
Éra N-Fix is a microbial product designed to fix atmospheric nitrogen. It delivers a continuous nitrogen supply throughout the plant's growth cycle. It is formulated from two Paenibacillus polymyxa strains and one Bacillus velezensis strain. It promotes vigorous root development. It enriches the rhizosphere microbiome. It also exerts broad-spectrum antagonistic activity against plant pathogens.
Who It's
It's For Field and greenhouse crops, flowering plants, all growing media and soil types. Ideal as a complement to Éra Boost Pro from transplant onward.
Key Benefits
√ Atmospheric nitrogen fixation for continuous, natural nitrogen supply
√ Vigorous root development from establishment
√ Broad-spectrum antagonist activity against plant pathogens
√ Enzymatic enrichment of the rhizosphere
√ Reduced dependence on nitrogen fertilizers
Mode of Action
Biological Nitrogen Fixation
Two bacterial strains present in Éra N-Fix fix atmospheric nitrogen (N₂) via the nitrogenase enzyme complex, encoded by the nifH gene. Nitrogen is converted into ammonium (NH₄⁺) directly assimilable by the plant, reducing dependence on synthetic nitrogen fertilizers.
Broad-Spectrum Antagonist Activity
The Bacillus velezensis strain synthesizes antifungal and antibacterial lipopeptides — iturin A, surfactin, and fengycin — that inhibit the development of foliar and root pathogens. This strain also induces systemic resistance (ISR) in the host plant. For their part, Paenibacillus polymyxa strains secrete natural enzymes and antibiotics that affect the growth of plant pests.
Greenhouse Microbiome Engineering
The three strains in Éra N-Fix work together to reshape the rhizosphere microbiome in favor of the plant. Auxin (IAA) production stimulates root elongation and branching, increasing nutrient absorption surface area. The Paenibacillus polymyxa strains also produce cytokinins that accelerate root cell division from the first days after transplanting. Together, these bacterial interactions create a structured rhizosphere environment, promoting a living and resilient growing medium.
