bi protect

Product description:

bi protect is the only soil microbial fertilizer of high quality on the Polish market which accelerates decomposition of organic matter, takes part in the formation of soil structure, improves the phytosanitary condition and provides nutrients to plants. It is based on single, carefully selected Bacillus subtilis bacteria.


Bacillus subtilis in the amount 5x109 CFU in 1 gram of the product.

Product for organic farming

The bacteria contained in the preparation:

Contributes to the tuberous structure of the soil

Forms soil colloids

Improves plant health

Supports the growth of beneficial soil bacteria

Helps in the decomposition of organic matter


The bacterium Bacillus subtilis is commonly found in soil in our climatic zone. It is a saprophyte, decomposing organic compounds of plant origin (mainly carbohydrates and pectins). Additionally, the bacterium produces peptide antibiotics, such as polymyxin B and subtilin, as well as amino acids, polysaccharide - inulin and enzymes such as amylase and protease. It also forms siderophores (bacillobactin), which have the ability to bind iron ions by binding all available forms of iron into chelates and making them available to plants. The protein of these bacteria also contains hydrophobin BsIA, which is surface active and reduces surface tension, thus increasing the wetting of the surface on which the bacteria are located, leading to an improvement in moisture within the root system and covering it with an additional protective film (especially during dry periods). It also stabilizes soil colloids.

The Bacillus subtilis bacterium reduces the number of pathogenic fungi and bacteria in the soil contributing to the improvement of the phytosanitary status in the crops. This bacterium multiplies quickly, so through competition for food and space in relation to other pathogens, it eliminates them in a natural way from the soil environment, supporting the development of beneficial soil microorganisms. It is the only preparation on the market in powder form containing such a huge amount of bacteria in pure form in 1 gram.

Move the table

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.
