Lactobacillus casei 21

Lactobacillus casei is a collective group of lactic acid bacteria that play a critical role in creating a suppressive environment within the rhizosphere. These microorganisms ferment organic residues, converting complex compounds into simpler, bioavailable forms that the root system can easily assimilate.

Throughout their life cycle, they produce organic acids, such as lactic acid, which contribute to the acidification of the soil solution. This localized pH adjustment helps mobilize difficult-to-access forms of phosphorus and micronutrients bound in soil colloids, making them available for plant uptake.

This group of bacteria fosters a robust biocenosis in the rhizosphere, actively competing with pathogenic microflora for space and nutrients. Their metabolic activity increases overall soil biological health, which positively influences the growth rates of various crops.

In addition to direct metabolic involvement, these bacteria produce bioactive metabolites that stimulate cell division in root hairs. This results in an increased absorptive surface area of the root system, significantly improving water uptake and the mineral nutrition of the crops.

In modern agricultural practices, products based on this bacterial group are utilized as biological catalysts for the decomposition of crop residues. They accelerate humification processes, transforming organic matter into stable humus, which serves as a major nutrient reservoir for agricultural production.

Lactobacillus casei is effective against a variety of soil-borne phytopathogens, including those responsible for root rot and Fusarium wilt. By secreting bacteriocins and acidifying the environment, they suppress the development of mold fungi and bacterial soft rots.

These products are applied through seed treatment, soil application prior to planting, or via fertigation during the active growth period. Working solution concentrations should be adjusted according to the specific product guidelines based on the individual strains within the group.

Optimal application timing occurs during spring soil preparation and throughout active vegetation stages. For maximum effectiveness, it is recommended to apply these products under conditions of sufficient moisture, as an aqueous environment is essential for the metabolic activity of these microorganisms.

The efficacy of this bacterial group diminishes under severe temperature fluctuations and extreme soil pH levels exceeding 8.5. Furthermore, they are highly sensitive to direct exposure to strong chemical fungicides and antibiotics, which can completely eradicate the bacterial population in the soil.
