Soybean inoculant Rhyzobium inoculant range, various strains

N-fixing bacteria to reduce chemical fertilizer use

Stimuplant is a specialized range of inoculants designed for various legume crops. It capitalizes on a unique symbiotic relationship between the legume plants and a beneficial bacterium known as Rhizobia. This natural partnership results in the addition of significant nitrogen levels to the soil, ranging from 40 to 150 kg per hectare.


This technology is pre-validated.

  • Nitrogen Limitation for Growth: Plants, especially legume crops, encounter restricted availability of nitrogen (N) in the soil, hindering their growth.

  • Soil Degradation from Fertilizer Reliance: Overdependence on chemical fertilizers has contributed to soil degradation over time.

  • Economic and Food Insecurity: The aforementioned issues collectively result in economic challenges and food insecurity for farmers.


  • UPL Powder Carrier Technology: Leveraging UPL powder carrier technology provides a protective shield for bacteria, safeguarding them against harsh environmental conditions like high temperatures and pH fluctuations.

  • CERES Organic Certification: The technology carries the prestigious CERES organic certification, ensuring compliance with rigorous organic standards.

  • Tailored Packaging for Smallholder Farmers: The packaging is specifically designed to suit the practical needs of smallholder farmers, enhancing accessibility and usability.

  • Extended Shelf Life: The powder formulation extends the shelf life of the product, offering a longer period of usability (9 months instead of 6), contributing to reduced wastage and increased efficiency.

Key points to design your business plan

Utilizing Rhyzobium Inoculant technology ensures economically viable and sustainable farming practices, enhancing both crop yields and soil health while reducing dependence on costly fertilizers. This fosters economic advantages and promotes efficient, eco-friendly agricultural methods.

As key partners, you require suppliers of Rhyzobium Inoculant.

The cost structure ranges from 15 to 25 USD per hectare, varying depending on the crop and country. Storage costs are minimal, given that only 100g per hectare are typically required on average. It's important to store the product between 4 and 24°C and away from pesticides.

Estimating the profitability resulting from the product's use is essential.

Seed treatment process :

For large quantities use a concrete mixer.

For small quantities use a plastic bag as follow:

  • Add the inoculant, seed (e.g., 1kg), and sticker as per the label instructions to the plastic bag.
  • Do not use water with groundnut seeds.
  • Close the bag and swirl it until all seeds are treated.
  • Allow the treated seeds to dry in a cool place, away from direct sunlight.

Plant directly after inoculation and drying.

Avoid planting seeds with nitrogen fertilizer for up to 8 weeks, as it can harm the nodulation process.

Also, avoid direct contact with Superphosphate during and after inoculation.
