WHY INOCULATE? 

Rhizobia bacteria populations from previous soybean crops may NOT be at adequate levels to ensure thorough, early nodulation of current crop. Early formation of nodules on the main root is critical to efficient conversion of N in soybean plants. 

Rhizobia are living organisms that are affected by soil and environmental conditions. Some of these conditions include- 

·        Sandy, gravelly knolls and ridges that dry out during hot, dry summers

·        Low organic matter levels (< 3.0)

·        Acidic soils  (ph < 6.0)

·        Wet spots due to poor surface drainage or sub-surface springs

·        Hot, dry seasons can significantly reduce residual rhizobia populations

·        Rhizobia are subject to attack by other soil organisms. The longer the rotation, the higher the chance of having reduced populations

 

Some or all of the above can contribute to less than ideal levels of rhizobia in areas within even the best fields.

 

Applying inoculants on the seed - or into the furrow - is the most effective and economical way to provide conditions for adequate and early nodulation. 

IS THERE A PAYBACK ? 

Long term studies and data from various public and private research sources, such as:

·         OMAF  Web Site

·         Ohio State University (5 year study)

·         Compilation of 9 years results from 243 sites across US and Ontario (Nitragin, Inc)

 

Have shown a consistent increase  in soybean yields on rotated soybean ground compared to uninoculated soybeans.( Average 1.6 bu./acre). To look at the payback, consider this example:

  • At FULL rate, Cell-Tech Soybean liquid inoculant costs $2.19 per acre.

 

  • Assume yield is increased by 1.6 bushels/acre, and beans sell for $7.00/bu.
  • That’s $11.20/acre of additional revenue. That’s 5 times the return on the investment.

 

Is there a payback?     YES !!
