Effects Of Excessive Rainfall on Fall Applied Ammonia

by Greg Peters | Jan 8, 2016

I don’t think anyone would argue the fact that we have been on a roller-coaster for weather since 2009.  2015 was no exception and December brought record rainfall to much of the crop production areas and abnormally warm temperatures to the eastern portion of the US.

Fall applications of Ammonia have increase in recent years as farming operations have increased in size because of its time savings in the spring.  Fall applied ammonia generally offers other incentives such as price savings, less concern with ammonia burn and helps with tax management.  This works well as long as the fall and spring are relatively dry, preventing the loss of converted ammonium to nitrates.  I don’t think I can remember a winter were we have had extreme moisture conditions like this year.  This is leading to many questions about the N loss potential from the late rains.
