Brief Project Summary:

Cover crops can increase soil organic matter, soil tilth, water infiltration, nutrient capture, weed control and reduce soil erosion. This 3-year project would assess the timing of termination of wheat or rye cover crops relative to soybean planting on farmer fields across eastern and central Nebraska. Sites would consist of an existing rye or wheat cover crop terminated with glyphosate using a backpack sprayer at three different times during the spring prior to and after soybean planting. Soybean fields will be evaluated twice during the early vegetative stage and once during the reproductive stage for insects, plant damage, and yield will be recorded on plots.

Information And Results
Project Deliverables

Resulting data from this project would be presented at a number of Extension outreach events such as the Soybean Management Field Days (minimum 350 attendees), Nebraska Crop Management Conference (approx. 300 attendees), Eastern Nebraska Research and Extension Center Cover Crop Conference (approx. 300 attendees), as well as number of other county and research center based field days. Updates on research progress would be presented through Twitter, Market Journal interviews and CropWatch articles. Time-lapse videos will also be compiled and presented through a number of Extension venues. It is expected that at least two peer-reviewed publications will result from this work.

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.
