Additional Information

Legume Inoculation

Legumes such as beans, peas, clover and alfalfa are able to access (“fix”) nitrogen because their roots host symbiotic bacteria of the genus Rhizobium. The plant roots feed the bacteria while the bacteria take molecular nitrogen from the air and convert it to a form that the plant can use.

Different legumes require different species of rhizobia to form a successful relationship.

Legumes take up nitrogen from the soil like other plants, and in fact do so in preference to the energy-intensive process of nitrogen fixation if soil nitrogen is plentiful. If you are growing leguminous crops in nitrogen-rich soil, inoculation may produce little yield benefit. However, nitrogen fixation cannot take place without the requisite rhizobia: if you are planting legumes in poor soil or planting a leguminous cover crop to build soil nitrogen, inoculation is non-negotiable.

Store inoculant in a cool, dry place out of direct sunlight. We recommend using fresh inoculant each time you plant a legume even if you have planted inoculated seed in the same spot before. Fresh inoculant ensures an immediate increase in bacterial populations. When you are ready to put the seed in the ground, moisten it with water, pour the inoculant over it and mix. Protect from direct sunlight and plant before the seed dries out, or remoisten and remix. Plant immediately if planting by hand; by machine, you’ll need to let seed dry to prevent clogging, but plant as soon as the seed has dried.

Our inoculants do not contain genetically modified materials.

WSDA: Listed by the Washington State Department of Agriculture’s Organic Certification division for use in organic agriculture in Washington State. MOFGA has indicated that they will accept products on this list for their certification program. Check with your certifier.
Nat’l List: One-ingredient products on the NOP* List of Allowed Substances (subpart G of the Organic Foods Production Act, sections 205.601-606). Check with your certifier.
AYC: Ask your certifier. Has not been reviewed by a certifier, but the active ingredient is allowed. Ask your certifier.
Not Allowed: A few of the products we list are not allowed for organic production but we think they have a place in sensible agriculture and can be used when certification is not an issue.
