Nitrogen Management

One of the problems with fall Nitrogen application, other than wasting money on nitrogen loss, is that the lost nitrogen has potential to enter drainage tile and eventually surface water.  I will admit that an advantage to applying nitrogen in  the fall is that it leaves one less thing to do in spring.  If that is your motivation, you still need to consider 3 things.  One is that nitrogen should not be applied till soil temperature reaches 50 degrees. Use nitrification inhibitor.  The last is, consider a bio-reactor.  No-till Farmer just published an article on bio-reactors.
