Built for this crop
Alfalfa fixes nitrogen well only when effective Sinorhizobium meliloti is present, yet many soils — especially alkaline, saline, or first-time alfalfa ground — lack it or carry weak strains; poor early nodulation means thin stands, lower protein, and wasted fertilizer.
Nodu™ ALF establishes a vigorous Sinorhizobium meliloti symbiosis from sowing.
Packaging and label information may vary by product version and market.
The right strain for Alfalfa
Nodu™ delivers Sinorhizobium (Ensifer) meliloti, matched to your region and confirmed against local populations before it ships — because rhizobia are host-specific.
Nitrogen you don’t have to buy
A well-nodulated legume draws 50–75% of its nitrogen from the air. On Alfalfa: Fixes ~150–250+ kg N/ha per year; builds soil N for the rotation.
Strong, early nodulation
Vigorous nodulation establishes within ~2–3 weeks of sowing, with 3–6× more nodules per plant than uninoculated controls.

Trial sites
Alfalfa sits in its own cross-inoculation group — Medicago, Melilotus (sweet clover) and Trigonella (fenugreek) — nodulated by fast-growing Sinorhizobium (Ensifer) meliloti, not the Bradyrhizobium or Rhizobium groups that serve the other legumes; strongly acid soils call for the closely related S. medicae. Nodu™ ALF is built on elite, region-matched S. meliloti (the symbiosis behind the world’s leading alfalfa inoculants) and confirmed against your soil’s resident populations, which are often sparse or weak in first-time or strongly alkaline-saline fields; Orvan™ amplifies those rhizobia rather than replacing them.
What's inside
Elite Bradyrhizobium / Rhizobium inoculants that establish a strong, early, and persistent nitrogen-fixing symbiosis in legumes, so the crop fixes more of its own nitrogen and you buy less.
Live rhizobia colonize the root, form nodules, and reduce atmospheric nitrogen (N₂) to a plant-available form throughout the season, lifting early vigor, biomass, and yield. Because rhizobia are host-specific, each legume needs its own compatible strain, selected for local soil conditions and confirmed against local populations before deployment.
Nodu™ science →Strains
Crop-specific and region-matched: soybean-specific Bradyrhizobium japonicum / diazoefficiens (USDA 110-type); fast-growing Rhizobium tropici (CIAT 899-type) for common bean; cowpea-miscellany Bradyrhizobium (incl. BR 3267-type) for peanut, cowpea, mung bean, black gram and pigeon pea; and Sinorhizobium (Ensifer) meliloti for alfalfa. One SKU per crop.
Good to know
Nodu™ delivers the nitrogen-fixing rhizobia, the symbiotic partner the crop needs. It is built to work with Orvan™, a rhizosphere-coordination consortium applied alongside or on top of the rhizobial inoculant that strengthens the nodulation environment, and with Vigor™ for roots and phosphorus.
How to use · Nodu™
Inoculate seed in shade just before sowing and sow within 24–72 h, or apply the liquid in-furrow. Apply after any fungicide seed treatment; keep away from chlorinated water (> 2 ppm) and strong acids/alkali. Co-applies with Vigor™ and Orvan™.
The full program · Alfalfa
At sowing: Nodu™ ALF seed coat or slurry (Sinorhizobium meliloti); Vigor™ in-furrow or on seed; Orvan™ as the coupled program. Re-inoculate at each reseeding and on high-pH or low-rhizobia soils.

Common questions
Can I use it with a fungicide seed treatment and my other inoculants?+
Yes. Nodu™ co-applies with Orvan™, Vigor™ and starter NPK. Inoculate in the shade after Orvan™ has been applied, sow within 24–72 hours, and keep the rhizobia away from copper fungicides, strong alkali (pH > 9) and chlorinated water (> 2 ppm). Rhizobia are the most heat- and desiccation-sensitive of the three, so inoculated seed should not be left in the sun or held overnight.
Which formulation should I choose for Alfalfa?+
We match the format to your crop, planter and conditions — granule banded with base fertilizer, liquid in-furrow, or an on-seed treatment. Tell us your setup and we’ll recommend the right one.
Do you ship internationally, and what documents are included?+
Yes. Each shipment comes with the technical data sheet and a safety data sheet (granule); phytosanitary and import documents are prepared per destination market. Contact us for your country.
How should it be stored, and what is the shelf life?+
Store cool, dry and out of direct sunlight; do not freeze liquid forms. Shelf life is formulation-dependent — see the data sheet for the exact figure by format.
Is the product safe and non-GMO?+
Yes. All strains are naturally isolated, non-GMO and handled as low-risk (BSL-1). The product is registered with China’s MARA and meets the heavy-metal limits of GB 38400-2019.
