According to study from Department of Natural Resources researchers, irrigation pivots stained with rust may indicate the absence of nitrate in the groundwater supplying the pivots. This information can potentially be used to help screen for areas for the potential absence of nitrate and, in an ideal world, could indicate areas at higher- or lower-risk for nitrate contamination before it becomes a problem.

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.

Northeast Nebraska farmers and agricultural professionals will learn about tools they can implement to mitigate nitrogen loss at the 2022 Bazile Groundwater Management Demonstration Field Day. Hosts for the day include Lewis and Clark NRD, Lower Elkhorn NRD, Lower Niobrara NRD and Upper Elkhorn NRD and local Nebraska Extension Water and Integrating Cropping Systems extension educators with funding provided from the Nebraska Environmental Trust. Speakers will address important tools that can be used to mitigate nitrogen loss. The BGMA Demo Field Day is scheduled for Thursday June 30, 2022 southeast of Creighton, Nebraska (From Hwy 59 and Hwy 14 Junction, go three miles south on Hwy 14, then one mile west on 869 Rd and a ½ mile south on 523 Ave.). The field day will start with registration at 1 p.m. with the educational programing starting at 1:30 p.m. and ends at 7 p.m.
