A low-cost step toward better yields and better margins.
Biofix is a soybean inoculant designed to improve nodulation and help the crop access more nitrogen through biological fixation. For farmers, inoculation is often the most practical and profitable starting point.
Built around evidence, not guesswork
The SMART Farm research model shows that soybean performs best when recommendations match the field and the farmer's budget — rather than applying every possible input by default. Inoculum consistently appears as the most common high-return add-on.
of recommended SMART Farm bundles included inoculum — more often than any other additional input.
Rhizobium inoculum was described in the SMART Farm summary as a low-cost input with large contributions to soybean nitrogen availability.
Research in western Kenya found higher soybean yields and gross margins among inoculant users than non-users.
Start where it makes sense for your field
The SMART Farm framework compares bundles by gross margin and recommends the most profitable option — not always the highest-yield or highest-input one. Biofix fits into a stepwise approach.
Biofix only
For farmers who want a low-cost entry into improved soybean production.
Biofix + certified seed
The foundational soybean package: inoculant, quality seed, and best management guidance.
Biofix + phosphorus
Add phosphorus or other recommended inputs based on your soil and field conditions.
Field-specific bundle
A tailored recommendation for farmers, groups, or partners who want a more precise pathway.
Application instructions
Biofix should be used on soybean seed before planting, following the product label and local technical guidance.
Inoculate before planting
Apply Biofix to soybean seed before planting, following the product label instructions.
Pair with best practices
Use certified seed, plant early, use row planting, maintain good plant population, and weed on time.
Combine where needed
Add phosphorus or lime based on your soil condition, budget, and local agronomic recommendations.
Store and handle carefully
Keep the product cool and dry. The living inoculant must remain effective — avoid exposing treated seed to harsh conditions before planting.
The numbers behind the product
Inoculum showed up in 68% of recommended SMART Farm bundles
Across SMART Farm trial sites, inoculum appeared more often than any other additional input. In western Kenya, inoculant users achieved higher soybean yields and gross margins than non-users. Other studies found inoculation with Biofix improved nodulation, grain yield, and profitability relative to uninoculated controls.

⚠️ A note on recommendations
The right soybean bundle depends on your field, your soil, and your budget. More inputs are not always more profitable — which is why Kumea positions Biofix as part of a smarter decision pathway rather than a one-size-fits-all promise.
