Product description

Bi nitrogen is the only high-quality bacterial preparation on the Polish market with a strictly directed action, based on single, carefully selected Bacillus nitrogenofixans bacteria.


Bacteria contained in the preparation:

  • They bind and mineralize nitrogen from the atmospheric air
  • They contribute to the lumpy structure of the soil
  • They have a positive effect on plant health and yielding
  • They reduce the occurrence of pathogens in the soil
  • They participate in the breakdown of organic matter


Bacillus nitrogenofixans in the amount of 1x109 JTK in 1 gram of the product.


Thanks to microbiological processes, nitrogen from the atmosphere is incorporated into organic compounds in cells. Nitrogen compounds occurring in organic remains are mineralized with the participation of microorganisms and recirculated in the atmosphere. It is known that nitrogen bacteria can bind up to 50 kg of nitrogen per 1 ha of cultivated area. This nitrogen in a form that is absorbed by other organisms (ammonium compounds, proteins) can continue to circulate in the biosphere. An excellent example of a nitrogenous bacterium naturally occurring in soil is Bacillus nitrogenofixans. In soils with low humus content, where intensive production is carried out, the decrease in the content of microorganisms may even reach several dozen percent. This is due to chemical fertilizers, herbicides, fungicides and insecticides as well as unfavorable environmental conditions.


The use of Bacillus Azitofixans on the soil in spring or autumn allows the population of this useful bacterium to be rebuilt. The use of bi-nitrogen containing this bacterium helps to improve nitrogen circulation in the soil, as well as the systematic supply of available forms of nitrogen for plants, which prevents the accumulation of nitrates and nitrites in them, and ensures a continuous supply of nitrogen, regardless of mineral fertilization.


It is the only preparation on the market in a loose form (powder) containing such a huge amount of bacteria in pure form per gram.

The bi-nitrogen preparation is approved by the Institute of Soil Science and Plant Cultivation for use in organic farming no .: SE / 25/2020.

The bi-nitrogen preparation is certified by the National Institute of Hygiene.



  • Agricultural plants 0.5 - 1 kg / 200 - 350 l of water / ha 1-2 times a season (in spring before sowing, or for plantation and autumn for crop residues)
  • Field vegetable crops 0.5 - 1 kg / 200 - 350 l of water / ha 2 - 3 times a season
  • Vegetables under cover 25 g / 60 - 100 m² 2 - 3 times a season
  • Fruit trees and bushes 0.5 - 1 kg / 400 - 600 l of water / ha 2 - 3 times a season
  • Blueberry: Strawberries, currants, raspberries 0.5 - 1 kg / 200 - 400 l of water / ha 2 - 3 times a season
  • Decomposition of harvest residues 0.5 - 1 kg / 200 - 300 l of water / ha in autumn

Additional information:

The bi-nitrogen preparation is certified by the National Institute of Hygiene.

The preparation should be applied to moist soil, preferably with the addition of Lignohumat Super humic acids (they promote the multiplication of bacteria).

Bacterial preparations should not be used in sunny weather and drought, and mixed with chemical preparations (fertilizers, PPC).
