BlueN is a nutrient efficiency biostimulant containing a natural bacteria, Methylobacterium symbioticum, that fixes nitrogen from the air and converts it into ammonium inside the plant.
BlueN provides a sustainable, supplemental source of nitrogen that reduces dependency of nitrogen uptake from the soil and ensures the plant has access to nitrogen all season long.
BlueN is approved for restricted organic use
BlueN provides a unique way to enable plants to capture nitrogen thoughought the season.
BlueN is classed as a foliar applied biostimulant, composed of an exclusive strain of naturally occurring endophytic bacteria, Methylobacterium symbioticum. M. symbioticum uses methanol given off by the plant during metabolic processes as an energy source to fix atmospheric nitrogen and convert it to ammonium inside the plant. Ammonium is used to make essential amino acids essential for plant growth.
BlueN enters the plant though the stomata. BlueN concentrates mainly in areas of growth in and around plant leaf cells. Broadly BlueN will take about 1 week to colonise a plant and will fix the equivalent to 3kg/ha of applied nitrogen per week thereafter usually about 30kg/ha per season (10-week crop). Therefore, once colonised, BlueN will provide a sustinable supplimental souce of nitrogen to the plant thoughout the season.

BlueN is approved for restricted organic use certified by the Organic Farmers & Growers.
BlueN enhances plant growth and resilience by producing a constant flow of nitrogen directly inside the plant, to the plant. This process occurs thoughout the growing season.
BlueN is simple to store and apply. BlueN has a shelf life of two years. Ideally, use BlueN on the day of opening. Read more on our application advice here as well as downloading our BlueN Applicator Optimiser on the Corteva Arable App.
Increasing nitrogen fertiliser does not necessariy result in more nitrogen becoming avilable to the plant; nitrogen fertiliser is subject to loss and is not always avilable when your crop needs it.
BlueN meets changing market expectations by providing a supplementary and sustinable source of nitrogen, without the risk of leaching or releasing additional greenhouse gases. BlueN reduces the dependency of nitrogen fertiliser uptake from the soil and ensures the plant has access to nitrogen all season long.
BlueN nutrient efficiency biostimulant is an effective solution for a range of crops. BlueN is intended for foliar application on authorised crops when at least 50% of the ground is covered by the crop. See the label for specific crops.

BlueN feed primarly off methanol produced by the plant during active metabolism. And because actively growing plants unaffected by stress will produce more methanol than stressed plants, BlueN should be applied to actively growing plants.
BlueN's bacterium, Methylobacterium symbioticum, enters via stomata on the plant's leaves. Therefore, best results are obtained when BlueN is applied to the foliar of a non-stressed crop when stomata are opened. Apply BlueN in the morning or late afternoon/evening.
BlueN colonisation can be slowed down if temperatures are too cool, or if too hot, the bacterium can die. The optimum day temperature for application is between 10°C - 30°C (ideally 15°C - 25°C).
Apply with sufficient plant biomass, usually when the crop cover is 50%, and when the crop presents good soil coverage.
Use water with a pH between 5 and 8.
The shelf life of BlueN is two years unopened. It is reccomended to use BlueN on the day of opening because the bacteria become activated once in contact with moisture. The shelf life of an opened pack can be up to one month, however this is difficult to achieve.
Apply BlueN at a rate of 333 g/ha. Rates below 333 g/ha do not deliver 3 x 107 CFU/g – the number required to produce a viable colonisation and expected biostimulation effects.
