bi fosfor

Product description:

bi fosfor is the only high-quality soil microbial fertilizer on the Polish market that helps enrich the soil in easily-absorbable phosphorus derived from the decomposition of its complex and insoluble forms. It stimulates plant growth which increases crop yield and quality. It is based on single, carefully selected phosphorus bacteria Bacillus megaterium.


Bacillus megaterium in the amount of 1x109 CFU in 1 gram of the product.

Product for organic farming

Bacteria contained in the preparation

Makes phosphorus available to plants from the soil

Supports humus formation

Contributes to the tuberous structure of the soil

Improves yield quantity and quality

Reduces the incidence of pathogens


Phosphorus, like nitrogen, takes part in all life processes in the plant. It is essential for the proper course of photosynthesis, respiration, metabolism and especially for the formation of proteins and spare substances (fats, phytin). Phosphorus deficiency causes serious disturbances in the basic life functions of plants, resulting in impaired development and functioning of individual organs, especially the root system.

Phosphorus is taken up from the soil by plants only in the form of phosphoric acid ions (V). Unfortunately, the proportion of soils in our country with low or very low available phosphorus content is as much as 40%. Therefore, the activity of phosphate solubilizing bacteria PSB (Phosphate Solubilizing Bacteria) is invaluable.

In addition to available phosphorus, PSB also introduces substances such as siderophores, auxins, cytokinins and vitamins into the soil. Therefore, in recent years phosphorus microorganism strains are considered as so-called "bio-fertilizer". PSB is an important factor in optimizing agricultural production.

The PSB group includes Bacillus megaterium "superbacteria" - when applied to soil, it improves its abundance in phosphorus forms available to plants. It breaks down volatilized and bound forms of phosphorus (including phosphorites) into readily available phosphorus for plants. Preparation bi fosfor contains strains of Bacillus megaterium in very large quantities and applied at a rate of 1 kg / ha can gain up to 20-40 kg of phosphorus in pure form per 1 hectare.

The preparation should be applied on humid soil, preferably with the addition of humus acids (they promote the multiplication of bacteria).

The microbiological preparations should not be used during sunny or dry weather, and should not be mixed with fungicides.

Visible effects

Additional information

The bi fosfor preparation is approved by the Institute of Soil Science and Plant Cultivation for use in organic farming No: SE/26/2020.

It is the only preparation on the market in powder form which contains such a huge amount of bacteria in 1 gram.
