Microorganisms play an essential role in soil biological dynamics and plant mineral nutrition.
The solutions we develop contribute to:
• improving nutrient bioavailability and absorption,
• enhancing root exploration,
• supporting plant growth.
Our products are adaptable to various agricultural systems:
• broadacre crops
• market gardening,
• viticulture,
• berries & small fruits
• tropical crops,
• as well as technical green spaces (golf courses, sports fields, professional gardening),
• and seed treatment.
Our approach is based on the rigorous selection and industrial-scale production of PGPR (Plant Growth-Promoting Rhizobacteria) strains characterized for their agronomic value.
Integrating our bacteria into optimized formulations guarantees microbiological stability and prolonged viability, allowing each strain to express its full metabolic potential within the rhizosphere.
Nitrogen
and micronutrients
Optimization of nutrient dynamics (nitrogen, phosphorus, iron, potassium, etc.)
→ Improved solubilization of locked-up mineral forms
→ Biological fixation of atmospheric nitrogen through symbiotic or free-living diazotrophic bacteria
Soil
structure
Performance of the soil-root complex
→ Improved root establishment through stimulation of root morphogenesis
→ Improved biological soil porosity and access to water resources
→ Increased root surface area and associated beneficial ecological niches
Abiotic
stress
Plant tolerance to environmental variations
→ Maintenance of cellular metabolism and consistent growth under fluctuating environmental conditions (water stress, salinity, temperature fluctuations).
These modes of action, which comply with the European regulatory framework for biostimulants, are designed to promote sustainable and high-performance plant nutrition.

Rhizosarb Alfalfa Long-Term is an inoculant formulated with a Sinorhizobium strain.
This product is the French standard for alfalfa establishment and long-term growth. The process relies on the formation of root nodules, which convert atmospheric nitrogen into directly metabolizable ammoniacal nitrogen.
• Ensures successful establishment in challenging soil and climate conditions.
• Optimizes nitrogen fixation potential, which can reach up to 80 units of N/ha/year, according to scientific literature
• Maximizes the protein content of forage.
Produced under an INRAe license for 45 years, Rhizosarb ensures consistent performance, a cornerstone of sustainable crop rotations.

This technology utilizes a rhizosphere bacterium capable of fixing atmospheric nitrogen asymbiotically. It provides the crop with a localized and continuous source of nitrogen, synchronized with the plant’s physiological needs.Strategic benefits:
• Reduction in mineral inputs
• Proven compatibility with conventional farming practices
• Supports plant vigor, particularly during critical periods of stress
• Reduces the farm’s carbon footprint
• No nitrogen leaching
In terms of nitrogen input, 20 kg of Azotilis can replace up to 10 metric tons of conventional mineral nitrogen fertilizer. As a substitute for traditional mineral fertilizers, Azotilis helps farmers reduce their farm’s carbon footprint. Furthermore, Azotilis integrates easily into existing fertilization programs without requiring changes to farming practices.

Innovation at Cybèle is based on an expanding microorganism bank and development programs tailored to real-world conditions. Our products have received numerous regulatory approvals.
With its comprehensive portfolio of marketing authorizations (MA), Cybèle-Agrocare is the French leader in beneficial plant bacteria.
Since the effectiveness of an inoculant depends on the specific nature of soil-plant interactions and the context of use, we present here a selection of our core technologies.
We invite you to consult our experts to identify the technology best suited to your specific challenges.
Developing a biostimulant or biofertilizer goes beyond simply selecting a microbial strain. Its effectiveness must be evaluated under real-world conditions.
Bacteria are living organisms that adapt their behavior based on:
• crops,
• farming practices,
• and soil and climate conditions.
That is why our team of agronomy experts conducts a comprehensive evaluation program each year that combines:
• greenhouse screenings,
• greenhouse trials
• and field experiments (micro-plots, strip trials, trials on farmers’ fields, etc.).
This work covers a wide range of crops (grains, corn, canola, sunflowers, soybeans, protein crops, forage crops, vegetable crops, berries, etc.).
The data generated allows us to refine our recommendations for use.

Our agronomic experts will work with you to develop trial protocols tailored to your specific conditions.
The integration of Bioprox Phéromones’ expertise into Cybèle-Agrocare enables the implementation of technical management programs that combine microbial nutrition with pest early-warning systems.
This systemic approach safeguards yield potential. The deployment of pheromone trapping solutions to monitor pest population dynamics allows for timely interventions and streamlines crop protection.
