Improve Your Crops Nutrient Use Efficiency with VIXERAN®
VIXERAN® is a proven bacteria-based technology that allows your crop to fix nitrogen directly from the atmosphere. The technology provides plants with an additional source of nitrogen where and when it's needed. As a result, nitrogen use efficiency on your farm improves – whether your crop production is organic or conventional. By utilising VIXERAN®, plants receive an additional source of nitrogen, effectively complementing the nitrogen supply from fertiliser treatments.
Fill the gap between the crop's nitrogen supply and demand
There are many situations where it is not possible to meet the nitrogen demand of the plant. Much of the nitrogen added through fertiliser application for example, can be lost through volatilisation or leaching. Applied in this peak demand stage, VIXERAN® supplies a reliable source of nitrogen to the crop.
What is VIXERAN®?
VIXERAN® is based on a bacterium called Azotobacter salinestris and is applied as a foliar treatment. Once added, it multiplies across the leaves and the roots, supporting the crops throughout the entire season.

Key benefits of VIXERAN®
Nitrogen efficiency
With VIXERAN® your crop gains access to a new natural nitrogen source to support crop development. It strengthens plant growth and increases yields by enhancing nutrient uptake
Tried and tested
Trials show shown that by applying VIXERAN®, up to 30 kg N per hectare can be fixed from the air. This helps the plant get the nitrogen it needs when it needs it
Easy to apply
VIXERAN® is applied as a foliar spray using standard equipment. Compatible with many products, it can often be integrated into regular crop spraying programmes.
Robust
VIXERAN® contain a particularly robust bacterium in that it can withstand external stress conditions, making it particularly suitable for foliar applications
How VIXERAN® enhances crop nitrogen uptake
The video demonstrates how the nitrogen-fixing bacteria in VIXERAN® penetrate the plant's leaves, roots, and root zone, fixing freely available nitrogen from the air and converting it into ammonium nitrogen that can be absorbed by the crop.
In a dormant state, the bacteria form cysts that protect them against unfavourable factors such as cold. However, when the bacteria come into contact with moisture and warmth, they are activated. The nitrogen that VIXERAN® fixes for the plant is not leached or evaporated.
Product details
| PRODUCT TYPE | Biological foliar treatment, biofertiliser. |
| BACTERIA | VIXERAN® contains the endophytic bacterium Azotobacter salinestris strain CECT 9690, which fixes atmospheric nitrogen and supplies it to the plant to be used for crop growth and development, leading to improved yield and quality. |
| TRIPLE MODE OF ACTION | The bacteria is able to colonise leaf, roots and rhizosphere, leading to a more consistent benefit. To aid the colonisation process it also creates a biofilm around the roots which aids the colonisation process, but also protects the bacteria & roots from soil phytopathogens. |
| CROPS | Cereals, Pulses, Maize, Oilseed rape, Potato. Sugar beet, Cover crops, permanent grassland. |
| DOSE RATE | 50 g/ha. |
| WATER VOLUME | 200-400 lt/ha to ensure good and even coverage. |
| COMPATIBILITY | VIXERAN® is compatible with many fertilisers, biostimulants and crop protection products. See compatibility list here. |
| ORGANIC | Approved for use in organic systems. Contact your certification body prior to use. |
How to optimise the application of VIXERAN®
VIXERAN® contains a living organism; therefore, this application advice is designed to support bacterial activity and a quick and effective colonisation.
Crop-specific recommendations for VIXERAN® application
VIXERAN® trials in the UK have been focused on cereals, pulse crops and potatoes but the product can be used in a wide range of crops. See recommendations below.
VIXERAN® is applied at a dose rate of 50 g/ha.
Since the bacteria is active both inside the plant and in the rhizosphere, aiding the effective colonisation of the foliage and root system, it is crucial to get a good coverage of the soil as well as the foliage.
| Crop | Recommended application timing |
| Spring cereals | GS12-16 (two to six leaves unfolded) |
| Winter cereals | GS25-30 (mid-tillering – start stem extension) |
| Pulses | GS16 (six leaves unfolded) to start of flowering |
| Maize | GS12-16 (two to six leaves unfolded) up to VT (unfolded tassel) |
| Oilseed rape | GS11-16 (first to six leaves unfolded) to GS29-31 (end of shoot development to one visibly extended internode) |
| Potato | BBCH 40 (start of tuber initiation) |
| Sugar beet | GS12-16 (two to six leaves unfolded) |
| Cover crops | 1 week post emergence |
| Permanent grassland | Early spring regrowth |
| Vegetables, ornamental aromatic and medicinal plants | From sowing/transplant to harvest |
| Woody perennial crops | From beginning of vegetation period to harvest |

Unique benefits of VIXERAN® technology
The VIXERAN® bacterial strain is unique in its high nitrogen fixation activity and its triple mode of action – working as a foliar endophyte, root endophyte and in the soil rhizosphere.
Azotobacter salinestris can form protective cysts, allowing it to survive harsh conditions and reactivate when the environment improves.
The bacteria can create a biofilm around plant roots, shielding against soil pathogens and providing both internal and external plant protection.
Azotobacter salinestris is a free-living bacteria that can survive in soil and within plants, benefitting plant and rhizosphere.
Frequently Asked Questions: VIXERAN®
It is best practice to premix wettable powders. Add 1 sachet of VIXERAN® to min. 1.25L of water. Warmer water (+ 5°C ) will make it solve quicker. VIXERAN® can be added directly to the induction hopper with the recommended volume of water if required.
