What is it and when should it be done?
It is vital for farmers who want to achieve maximum yields in their legume crops to double inoculate with live nitrogen fixing bacteria, especially if under harsh conditions.
What is Inoculation?
Inoculation is the application of massive amounts of Rhizobia bacteria either to the legume seed or to the soil into which the legume will be planted. Inoculant should not be confused with seed treatments which help to protect the seedling from disease.
Exceed® inoculants manufactured by Visjon Biologics offer the grower an advantage in the
field through the addition of fresh and plentiful nitrogen-fixing bacteria. The symbiotic relationship the Rhizobium bacteria has with your legume crop enables the seed to germinate quickly and stimulates plant hormones responsible for root formation and development. This brings more nourishment to the plant, which is evident by rapid and healthy growth with high-yield return.
With high numbers of aggressive nitrogen-fixing rhizobia bacteria:
Every legume planted can fully reach it's yield potential
Yield is improved in harsh conditions
Full-field yield averages increase
Why Double Inoculate?
Seed applied inoculants tend to form nodules closer to the location of the seed; in-furrow applied inoculants tend to form nodules on the secondary or lateral roots. By combining the two applications methods you allow for a wider distribution of nodules along the entire root system.
How do I Double Inoculate?
Double inoculation is an application method for rhizobium inoculant that combines seed-applied inoculants with a sequential in-furrow application of a liquid or granular inoculant. Double inoculation can help quickly establish high populations of rhizobia bacteria to ensure optimal nodulation and legume performance. Double Inoculate does not mean applying double the published application rate.
When should I Double Inoculate?
Like any living creature, rhizobia need the right conditions to survive. Certain events and practices can lead your soil to need replenishment beyond what fertilizer can provide. The following conditions can benefit from double inoculation:
Extremely high or low pH levels - Above 7.8 or below 5.5
Low organic matter levels
Conservation Reserve Program (CRP) Land
Drought or flood
High soil temperatures
Soils that have been fumigated.
Land that has been used for pasture.
