Got Inoculants?

Got inoculants?

If you’re on your second or third succession planting of beans or anticipating a fall planting of peas, it may be important for you to think about using inoculants in your garden or field.

Why use inoculants?  Inoculants help to maximize plant growth and yields by increasing the number of naturally occurring Rhizobia bacteria in the soil directly where the root system develops.  This is particularly beneficial if your soil has lost fertility from reuse year after year and will help the soil regain productivity over time.

Rhizobia are a type of bacteria that fix nitrogen in the soil, so long as they are hosted by the roots of a legume.  Inoculants will not be active in the soil if they do not have a host plant.  Inoculants are applied in the field at the time of planting, on the seeds or in the hole.

Here are some basic instructions:

Sprinkle Method: Moisten seed in a planter box at a rate of 2 oz. of clean, non-chlorinated water per 8 pounds of seed.  Add contents of the bag to the wet seed until seed is completely covered. Plant seed as soon as possible.

Slurry Method: Place contents of bag in 4.5 oz. of clean, non-chlorinated water and stir inoculant and water thoroughly. Mix seed and slurry in a container outside of planter box and plant seed as soon as possible.


  • Once seed has been inoculated, keep inoculated seed out of direct sunlight or hot drying winds.
  • Re-inoculate seed if not planted within 24 hours of application.

    When I planted my yard long pole beans, I sprinkled some inoculant in the hole before dropping the beans in. Then I watered well. Will that inoculant be beneficial at all?
