Inoculation of Legumes for Maximum Nitrogen Fixation
Additional inoculation information via the Forage Information System (FIS)
If the lack of effective nodulation on a newly seeded crop is known or feared, then inoculant can be applied to the crop in the field. Nodulation deficiencies can be corrected, although not entirely overcome, by salvage (emergency) inoculation up to four weeks after seedling emergence. The grower may use one of several techniques and expect equal results. Rate of application of actual inoculant should be in the range of 1 1/4 to 1 3/4 pounds per acre regardless of the application method. The methods are:
If the crop was fall-seeded and if cold weather has set in, then salvage inoculation should be delayed until early spring when the soil is warmer.
