2022 October Stewardship Advocate

Posted on November 1, 2022 at 8:54 AM by Stewardship Advocate

As harvest is wrapping up and colder weather is on the horizon, soil temperatures are nearly in the safe zone for fall nitrogen applications.  Risk of nitrogen loss is reduced when soil temperatures are consistently below 50 degrees.  Be sure to test your soil to account for this nitrogen and make sure it doesn’t leave the soil and cause water quality problems in the spring.  Here are some nitrogen management recommendations:

  • Verify soil nitrate levels with soil testing before fall applications.
  • All fall nitrogen applications should have a nitrification stabilizer.
  • Take advantage of residual soil nitrate and consider split applications.
  • Plant cover crops, which can easily retain more than 25 lbs of nitrogen per acre.
