Nitrogen and Cool, Wet Weather: Update from NREC Research Sites

Today, Dr. Emerson Nafziger at UI posted a bulletin on the cool and wet conditions, the impact on planting and the status of nitrogen in the soil.  One sentence in the bulletin states:  "It would be premature to predict the loss of fall applied N at this point."  Click here to read the bulletin, which draws upon soil tests performed at numerous NREC funded research sites to evaluate and track the levels of applied nitrogen and mineralized nitrogen, and their levels in the soil profile.  Please utilize this current information to promote responsible nitrogen management and, as Dr. Nafziger states, "There is no need to try to replace N before we can tell it's missing."  
IFCA works closely with drinking water supply officials and they inform of us each month of the nitrate levels in the lakes.  If you want to see how Lake Decatur, Lake Springfield and Lake Vermilion are looking with nitrate levels, click here.  If you have any questions about IFCA's Keep it 4R Crop Program and how we are working to reduce N losses by providing timely information to our members and to water supply stakeholders, please contact IFCA.  Thanks to all of our members who are promoting the 4Rs in all kinds of weather conditions.  Keep up the great work!
