Brief Project Summary:

Many fields in western North Dakota are having issues with pH values below 5.5. The best management practice in no-till is a surface application of lime, however it takes a large amount to change soil chemistry to adequate levels. Producers are searching for less costly short-term options. This project will compare lime, gypsum, and phosphorous treatments applied with the soybean seed in acidic soil to observe impact on yield and growth. Also observed will be plant stand and vigor. The economic values of each strategy will be calculated. Outcomes will be shared with farmers and experts in the geographic area.

Key Benefactors:
farmers, agronomists, applicators, extension specialists

In 2021 after the trial was planted a mixture of drought, hail, and off-target herbicide damage created a large amount of variance in the trial and greatly reduced stands. Any data collected would have been useless. When the site was hailed out we pivoted with approval from Miki to use the dollars for outreach and demonstration supplies. In the winter of 2021/2022 we had started to grow a few demonstrations pots for use at winter meetings, but I faced some medical issues and was not able to make it to many winter meetings due to being on sick leave for over a month. In the spring of 2022 we planted multiple pots with the intent of showing them at our Dickinson Agronomy Field Day. Unfortunately, on June 20th 2022 a storm came through Dickinson and hail wiped out the demonstration pots we had growing outside. New demonstration pots including root boxes and other displays have been replanted and will be shown at various workshops over the summer. The newly funded trial has been planted for 2022 at a site with soil pH below 5.5, hopefully the weather will finally cooperate with us. We will continue to use the demonstration supplies to educate on this issue.

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.
