Figure 1. A research plot at the university’s Eastern Nebraska Research and Extension Center (ENREC) near Mead on May 13, 2019. The entire plot is covered with no-till corn residue. The west half also is covered with a November 17 planted cereal rye cover crop. Soil temperatures 2 inches deep were recorded in each half, but were essentially the same, so are averaged in this report.

Soybean Germination/Emergence with April Planting Dates Relative to Coincident Air and Soil Temperatures in April and May May 16, 2019

A closer look at air and soil temperatures in April and soybean germination and emergence from 10 planting dates did not find chilling injury, despite periods below 50°F. Further research is needed to better understand the imbibitional period in soybean.

Considerations when Planting Soybean Early April 25, 2019

If you're planning to get an early start on your soybean planting, be sure to check for recommended soil temperatures and the forecast for the coming 48 hours to ensure optimal conditions for achieving good emergence.

Anhydrous Ammonia Conversion April 18, 2019

The environmental conditions allowing for anhydrous injury in 2018 are different then what we are experiencing this year. This brief looks at factors affecting the conversion from ammonia to usable soil nitrate.

Combining soybeans in 2018 — University researchers are seeking 20 growers in eastern Nebraska to study practices to improve soybean yields.

Study Area Expanded for Growers Interested in Participating in Soybean Yield Gap Research March 28, 2019

The Nebraska On-Farm Research Network (NOFRN) has expanded the area where it is seeking 20 farmers to study how to optimize soybean yields. Here's more on the practices being studied and what's needed from the growers and the university researchers.
