Microbial biostimulants for the root zone

BIOMICROBES brings selected live microorganisms to the environment where crop development begins: the root zone. Our microbial formulations support root development, nutrient use efficiency and biological activity around the roots within professional growing programs for soil, substrate and hydroponic cultivation.

Microbial biostimulants

Live microorganisms as part of the growing program

Microbial biostimulants are formulations containing selected live microorganisms.

Why composition and application differ

In the root zone they support natural biological processes related to root development, nutrient availability and use efficiency, and the crop’s response to changing growing conditions.

Properties differ by microorganism and by formulation. What matters is therefore not simply the presence of bacteria, but which microorganisms are applied, at what concentration and within which growing system.

The root zone

The rhizosphere is an active biological system

Immediately around the roots lies the rhizosphere: the zone where root exudates, microorganisms, water, oxygen and nutrients interact continuously.

What happens around the root?

Roots release compounds that influence microbial activity around the plant. At the same time, microorganisms respond to conditions such as moisture, temperature, oxygen, pH and available nutrients. An active rhizosphere therefore supports the biological basis for root and crop development.

Rhizosphere

The immediate zone around the plant root where the plant, microorganisms, water and available nutrients influence one another.

From microbiology to crop performance

What microbial biostimulants support in the root zone

Selected microorganisms can fulfill different functions within the root zone. The eventual contribution relates to the microorganism, the formulation, the application and the conditions in the growing system.

Root development

Supports the development of an active root system and a larger contact area between root and growing environment.

Nutrient use efficiency

Supports microbial processes that can make nutrients in the root zone more available and easier to use.

Microbial activity

Contributes to an active microbial environment around the roots, as part of a broader professional growing program.

Crop resilience

A vital crop with an active root zone is better equipped for changing growing conditions and develops more evenly.

In depth: what microbiology can do for your crop

The growing system

Results take shape within the complete growing system

A microbial formulation does not work in isolation. The crop, the root zone, the growing medium, water quality, application timing and other inputs together determine how microorganisms can establish and function.

That is why BIOMICROBES looks beyond the product itself and considers how it is applied within the existing growing program.

Crop and root zone The crop, its development stage and the conditions around the roots.
Soil, substrate or hydroponics Every growing environment offers different microbial conditions.
Water and application Water quality, dose, frequency and method of application.
Existing growing program Integration with fertilization, irrigation and other applied inputs.

Our microbial solutions

Different microorganisms for different roles

BM08, BM02, ROOT-N en HYDROPONICS each contain different microbial compositions. Every product therefore holds its own position within the BIOMICROBES portfolio and matches a specific application or growing environment.

Practical questions

Questions about microbial biostimulants

What the selected microorganisms support and why BIOMICROBES offers different products.

What do the microorganisms in BIOMICROBES products support?

BIOMICROBES selects microorganisms for targeted functions in the root zone: root development, rhizosphere activity and nutrient use. This way, our products strengthen the biological side of your growing program.

Why add bacteria when they are already present in the soil?

The presence of many microorganisms says nothing yet about which functions they perform under your growing conditions. With an inoculant, you introduce selected microorganisms at a chosen moment. Whether they persist and add something depends partly on the existing community, the crop and the environment. The aim is therefore a targeted addition; an existing soil community does not need to be removed first.

Do all microorganisms do the same thing?

No. Pseudomonas fluorescens, for example, forms siderophores that bind iron, Azotobacter vinelandii can fix atmospheric nitrogen as a free-living bacterium, and various Bacillus species are known for their role in nutrient processes and around the root. At the same time, different organisms can partly contribute to the same processes. A good choice therefore starts with the functions you want to support.

What role do microorganisms play around the roots?

The zone directly around the root is called the rhizosphere. Roots release sugars, amino acids and organic acids there, which microorganisms use as a food source. This creates an active interaction between plant, microorganisms and nutrients that plays a major role in how the root zone functions.

How do I choose the right solution?

Start with where the roots grow and the functions you want to support. In soil or substrate, our root zone products each have their own role, targeted or multi-species, and can also be used side by side; in a hydroponic system, that is HYDROPONICS.
