Manure’s Impact on Yield, Nitrogen, and Carbon May 3, 2018

If manure is applied at rates equal to or less than the nitrogen (N) requirement of a crop, can manure produce environmental benefits over commercial fertilizer? This article summarizes the "Take Home Messages" from a paper summarizing 141 studies relative to the question.

Corn leaves showing signs of nitrogen deficiency
Figure 1. Corn at V10 growth stage displaying symptoms of N deficiency (inverted V-shaped yellowing starting at the tip of lower leaves). Corn can display these symptoms when N supply is insufficient, possibly due to multiple reasons, including losses.

Nitrogen Fertilizer Stabilizers in Corn April 19, 2018

Understanding how the three types of nitrogen stabilizers work can be helpful in deciding whether to add one to your spring application. Short- and long-term studies in Nebraska offer insight into how they performed across multiple years. Now, if you only knew how many inches of rain you'd get the first six weeks after application.

Nebraska Soybean N Trials
Figure 1. Photos of one site of the Nebraska Extension Soybean Management Field Day research (2013) that compared the effects of several nitrogen treatments on soybeans. Pictured is the zero N control on the left and the 400 lbs/ac split N application on the right. Averaged over four sites the control yielded 73.4 bu/ac and the 400 lbs N averaged 78.9 bu/ac. (To view the results from this study, see https://go.unl.edu/smfdresults2013, pages 1-6.)

Nitrogen on Soybeans — the Hope Never Dies November 6, 2017

Nebraska Soil Scientist Charles Shapiro offers a synopsis of two new publications, both with University of Nebraska authors, that address the question of the nitrogen deficit between soil supply and nitrogen fixation and what affects whether increased nitrogen leads to increased yield.
