Fertilizer-nitrogen Injury to Corn
May 17, 2023
Nebraska Extension recommendations on minimizing crop injury from anhydrous ammonia applications.
Nebraska 4Rs Nutrient Stewardship Field Day Set for July 6
April 27, 2023
This year’s 4Rs Field Day will focus on up-to-date research information and demonstrations on all three major crop nutrients: nitrogen, phosphorus and potassium.
Don’t Lose Out on Free Nitrogen from Irrigation Water
April 20, 2023
Extension recommendations for calculating the amount of nitrate-nitrogen in irrigation water and optimal timing of applications to reduce the cost of nitrogen inputs in irrigated corn.
Alfalfa in Rotation with Annual Crops Reduces Nitrate Leaching Potential and Increases Soil Organic Carbon Sequestration
March 30, 2023
This UNL research study provides insights on the rotation of annual crops with alfalfa as a highly effective means of reducing nitrate-nitrogen contamination in groundwater.
Understanding Soil Residual Nitrogen and its Dollar Value for Next Crop
March 14, 2023
For producers planning corn-on-corn this growing season, there may be a substantial opportunity to reduce nitrogen fertilizer applications, as drought and reduced yields likely left higher-than-normal residual N in many fields.
Sensor-based Fertigation Management Research Boosts Efficiency, Profitability
March 9, 2023
Tested on cornfields in eastern Nebraska, the study's sensor-based fertigation produced about 44 pounds more grain per pound of nitrogen than traditional methods, with an increase in profitability ranging from $28-$40 per acre.
Husker Research Hones in on Sorghum’s Genetic Makeup to Improve Nitrogen Efficiency
October 6, 2022
This new research will focus on increasing sorghum’s fertilizer use efficiency, as well as other aspects of sorghum’s fertilizer use, including nitrogen sensing, signaling and downstream regulatory pathways.
Using a Cornstalk Nitrate Test to Evaluate Nitrogen Management Decisions
September 29, 2022
At the end of the season, a nitrate test can help determine whether the crop was under-, adequately or over-fertilized with nitrogen, resulting in the potential to significantly reduce input costs.
