Is Soybean Yield Limited by Nitrogen Supply?
January 8, 2018
An article from the Proceedings of the 2018 Nebraska Extension Crop Production Clinics exploring research on whether nitrogen supply is limiting soybean yield.
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.

SARE Grant Aids Farmer in Using Drones to Test N Applications
October 2, 2017
Dean Stevens well knows the value of getting a bird’s-eye view of his crops to assess plant health, wind damage, and pest threats. Now, with the support of an NCR SARE grant, this southeast Nebraska farmer is using a drone outfitted with crop sensors to assess corn nitrogen needs and respond with variable rate in-season applications.
Managing Nitrogen to Reduce Losses as Nitrous Oxide
September 18, 2017
Nitrogen is a key factor in farm management and economics. One of the most expensive inputs for corn production, it can be easily lost to the environment. One avenue for losing N, as nitrous oxide, has an impact on our climate as a greenhouse gas. Successful strategies for reducing N losses, especially as nitrous oxide, benefit both farmers and the environment.

Iowa Releases New Publication on Use of the Late Spring Soil Nitrate Test
June 8, 2017
Following heavy spring rains, farmers may be interested in testing for soil nitrogen availability. This article notes a new publication from Iowa State University on using the Late Spring Soil Nitrate Test (LSNT) as well as other options for assessing soil nitrate.
Risk of Nitrate Leaching Across Nebraska as of May 21, 2017
May 25, 2017
Following heavy spring rains UNL soil scientists model potential loss of nitrate-N to soil leaching, finding an average 14% loss from mid-April levels, with three sites with much higher losses.
