When and Why to Double Inoculate Your Soybeans

What is Double Inoculation?

Double inoculation is the act of using a double application of a rhizobial inoculant, such as:

  •  A double rate of​ Cell-Tech® Granular Soybean
  • Optimize® XC Liquid LCO Technology Soybean on-seed and Cell-Tech® Granular Soybean in-furrow

This quickly establishes high populations of rhizobia bacteria in the soil — bacteria that are critical to the nodulation process for soybeans and other legumes. By double inoculating, growers can help plants form nodules at an optimal rate and time, ultimately improving their overall performance potential.


What's In It For Me?

Double inoculation can provide access to nutrients bound in your soil, ultimately maximizing the performance potential of your soybeans.

  • Establishing high populations of rhizobia bacteria can help soybean plants form nitrogen-fixing nodules at an optimal rate and time. (Nitrogen drives the growth of roots, shoots, stems and leaves.)
  • Releasing bound nutrients from the soil can help you make use of what’s already there and make your fertilizer dollar go further.
  • Relying on nature’s powerful technology can help improve the sustainability of your operation.

 


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.​

  • Land that will be planted with soybeans for the first time
  • Land that has not been planted with soybeans in several years
  • Land with a history of longer soybean rotations
  • Land that been in the Conservation Reserve Program (CRP)
  • Land that has been used for pasture
  • Land that has a history of flooding or longer periods of drought



What About Stacking?

Stacking is similar to double inoculation, but it refers to using different products that play complementary roles. You can stack two seed-applied inoculants, or you can stack a seed-applied inoculant with an in-furrow inoculant. For example:


Optimize® XC Technology

Helps establish higher populations of beneficial Rhizobia in the soil, which are a critical part of nodulation and nitrogen fixation.

 

QuickRoots® Technology

Helps release nutrients bound in the soil, so they’re more available to the plant.

 


Try This: Stack Optimize® XC Inoculants and QuickRoots® Branded Inoculants


Optimize® XC Technology

Optimize® XC technology is applied directly to the seed. It contains beneficial rhizobia bacteria as well as another naturally occurring ​​​​​​molecule, which work together to enhance nodulation and give soybeans a healthy start.

 

QuickRoots® Technology

QuickRoots® technology, available in dry planter box and wettable powder formulations, contains two microbes that help make N, P and ​​​​​​​K in the soil more available to the plant.


These two technologies work together to create a powerful biological system, helping to establish populations of specially selected, nitrogen-fixing rhizobia in the soil, and improving the availability of N, P, and K.
