Brief Project Summary:

In the last decade, soybean acres have increased by 707,000 acres in NW MN. Spring wheat yields have risen from 47.8 in 2011 to 68.5 bu/acre in 2017, while reported soybean yields are relatively flat ranging from 35.7 in 2007 and 34.1 bu/acre in 2017. A 40 bu/acre soybean crop will require 33.6 # P205 and 52 # K20. With increased wheat yields and the potential increase in soybeans yields, P and K may be a limiting factor for plant growth development and yield in a wheat -soybean crop rotation.

A 2017 AGVISE soil survey in northwest MN indicated 67% had Phosphorus (P) levels of < 10 ppm and 39% had Potassium (K) levels < 150 ppm. This soil survey suggests over 2/3 of the soil samples for...

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.
