Fall Nitrogen Application Again

Today I saw two anhydrous nurse tanks leaving a supplier where I was working.  This raises some concerns on my part. 
  • First the soil temperature is above 50 degrees and probably warming up in the next few days. 
  • Second, our soils are very wet.  I am concerned that the slit will not seal properly
  • Third, if the soil does fix the nitrogen, it could start to denitrify immediately because of the wetness.
Famers and suppliers should both be cautious about fall nitrogen applications.
  • Wait till soil temperatures are at 50 degrees for good
  • Use nitrification inhibitor
  • Use anly ammonia products
  •  Wait for favorable moisture conditions
