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.
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.
Pasture and Forage Minute: Grazing High Nitrate Cornstalks, Late Summer Weed Control
September 14, 2022
Extension Educator Todd Whitney reveals techniques to safely graze drought-stressed cornstalks — plus, more on late summer weed control and planting small grains for spring forage.
Graze Drought-stressed Cornstalks Carefully
August 26, 2022
Cornstalk residue is a tremendous resource for fall and winter grazing; however, care needs to be taken in grazing drought-stressed cornstalks due to the potential of high nitrates in the feed this year.
