Manganese deficiency in Virginia soybean production has been a long time concern and received considerable research attention in the 1970s by faculty at Virginia Tech. These researchers found that soybean yields were generally lower in treatments that had soils with a higher pH; which mirrored soybean tissue manganese concentrations. Overall, they found that manganese deficiencies in conventional soybean varieties could be corrected using foliar, banded, or broadcast applications and the manganese application rate had to be adjusted. Scientists at Virginia Tech continued to work on manganese soil test and plant tissue tests through the early 1980s to help producers increase their...
The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
