Blu N

Innovation in nitrogen fixation: the mechanics of «Blue N»

«Blue N» from the Spanish company «Symborg Business Development S.L.» is an advanced biological solution designed to optimize the mineral nutrition of agricultural crops. The product is based on the endosymbiotic bacterium Methylobacterium symbioticum. Unlike conventional rhizospheric or nodule-forming bacteria, this strain colonizes the phyllosphere (above-ground parts) of the plant.

Technical specifications and mechanism

The product is supplied as water-soluble granules, ensuring high stability and simplified preparation of the tank mixture. Once applied to the leaves, the bacteria enter the plant tissues through the stomata, establishing a robust symbiotic relationship. Key technical benefits include:

• Autonomous nitrogen fixation: The bacteria convert atmospheric nitrogen into ammonium, providing the plant with essential nutrients throughout its entire vegetative growth period.
• Soil independence: The efficacy of Blue N is not restricted by soil acidity, organic matter content, or temperature fluctuations. This is a decisive factor for field crops like corn, sunflower, and winter cereals.
• Environmental and economic impact: By streamlining nitrogen metabolism, producers can lower the application rates of traditional mineral fertilizers without sacrificing yield, while also increasing plant tolerance to abiotic stress.

Performance in field application

«Blue N» is highly effective across a wide variety of crops, including vegetables, potatoes, rapeseed, soy, and cereals. With its Hazard Class 4 designation, the product is a safe and versatile component for integrated crop management (IPM) programs. Since M. symbioticum colonies operate within the plant itself, they continue to support physiological processes even during drought conditions when root system uptake is severely limited.
