Adapt-N User Group,

A brief update on the conditions in the Adapt-N user area at this critical time for corn N management (see also attached maps):

The Corn Belt has received only very modest amounts of rain in the past month, except for a wetter band in western Iowa and Minnesota. When looking at the departure from normal for the past month (a critical period for N losses), most areas are well below normal, except again in parts of Minnesota. With most fields being sidedressed around this time, the Adapt-N tool will generally recommend below average N rates for the region.

Most areas in the Northeast remain slightly above or below normal. New York State, Southern New England, and the Mid Atlantic Coast are generally dryer and will have below average N recommendations. Pennsylvania and northern New England are generally wetter with slightly higher recommended N rates. Southern Maine stands out as very wet.

In all, for most regions the Adapt-N tool will provide opportunities for considerable N savings, barring extreme precipitation events in the next weeks. In some areas, we may need to be concerned about drought, so let’s hope that they will get some rain.
