BactAlga: life for the soil, energy for the roots
In modern agriculture, fertilization efficiency depends not only on the amount of nutrients applied, but also on the plants’ ability to access them. Biological activity in the root zone plays an important role in this process, and the use of beneficial microorganisms is one of the approaches farmers can adopt to support soil function and crop development.
BactAlga is a water-soluble biological soil inoculant in powder form that combines PGPR bacteria, mycorrhizal fungi and a marine algae complex. Its formula is designed to support the interaction between soil, roots and nutrients, helping plants make more efficient use of available resources.
What are PGPR bacteria and why are they important for plants?
PGPR (Plant Growth-Promoting Rhizobacteria) are rhizosphere bacteria associated with the area surrounding plant roots. They can contribute to processes that are relevant to plant nutrition and development.
The BactAlga formula contains Azotobacter chroococcum, Priestia megaterium, Paenibacillus mucilaginosus and Paenibacillus polymyxa. According to the product technical information, this complex contributes to atmospheric nitrogen fixation, the solubilization of compounds containing phosphorus, potassium and silicon, and the conversion of N, P and K nutrients into forms that are available to plants.
In practical terms, the goal is not only to supply nutrients through the fertilization program, but also to support the plant’s access to available nutrients.
Bacteria, mycorrhizal fungi and marine algae in one formula
In addition to the microbial complex, BactAlga contains a mycorrhizal complex consisting of Rhizophagus irregularis, Septoglomus deserticola, Funneliformis mosseae, Claroideoglomus etunicatum and Claroideoglomus claroideum, as well as a 15% marine algae complex.
The product composition also includes 0.5% total nitrogen, 4% total potassium oxide (K₂O), 61.2% alginic acid and 81.7% organic matter.
Through this combination, the product is designed to support root system development, soil biodiversity and nutrient uptake.
How can BactAlga contribute to fertilization efficiency?
One of the key objectives of a modern fertilization program is to improve the efficiency of nutrients that have already been applied. According to the product’s technical information, BactAlga contributes to the solubilization of phosphorus, potassium and silicon, as well as to the conversion of nutrients into forms that are available to plants.
The formula is also designed to support root development and plant growth, soil biodiversity and plant resilience under drought conditions and in relation to other adverse biotic factors. The product also contributes to carbon fixation in the soil.
In practice, results depend on the crop, soil characteristics, climatic conditions, the farm’s cultivation practices, and correct application timing and dosage.
Which crops can BactAlga be used on?
BactAlga can be used in several ways, depending on the crop and the cultivation system.
For cereals, oilseed rape and maize, the product can be applied as a foliar treatment at the beginning of the growing season, at a rate of 0.2 kg/ha, as a single application.
For vegetable crops, BactAlga can be applied through the irrigation system 7–10 days after planting or transplanting, at a rate of 0.2–0.5 kg/ha, with a second application before flowering.
For fruit trees, application by watering the root zone is recommended in spring, at the beginning of the growing season, and in autumn, at a rate of 0.5–1 kg/ha.
BactAlga can also be used for seed treatment. The recommended rate for wheat and legumes such as soybeans, peas and beans is 1 kg/t, while for potatoes, other vegetables and ornamental plants, the recommended rate is 1–2 kg/t.
What should be considered when preparing and applying BactAlga?
For application, the required amount of BactAlga should be mixed with 200–400 litres of water until completely dissolved.
The product should be added last to the sprayer tank and, according to the product information, can be mixed with most biological products, fertilizers and pesticides unless otherwise specified by the manufacturer. The prepared solution should be used within 4–6 hours to maintain microorganism viability.
The application method should be selected according to the crop, growth stage and the farm’s cultivation practices. For recommendations tailored to specific farm conditions, consulting CICh technical representatives is recommended.
Biologically active soil as part of efficient fertilization
Modern fertilization involves more than simply applying a certain amount of nutrients. Their availability to plants, root system development and biological activity in the soil are also important factors.
By combining PGPR bacteria, mycorrhizal fungi and marine algae, BactAlga complements fertilization programs with a biological component designed to support these processes.
