Six-Inch Soil Temperature Network
This map shows where the MDA monitors soil temperatures at DNR/MPCA Cooperative Stream Gauge locations. It also shows locations where others are monitoring soil temperature including the University of Minnesota and the North Dakota NDAWN ag weather network.
MDA 6" soil temperature sites
University of Minnesota sites
NDAWN 4" soil temperature sites
Other sites (see note below)
How to use:
Simply click on one of the map markers to see the soil temperature. MDA sites provide a graph of soil temperatures over the past seven days. When a map marker is clicked additional site details will appear below.
Fall application of nitrogen fertilizer is not recommended in SE Minnesota due to high leaching potential. Soil temperature sites in SE Minnesota are included to assist in timing fall manure applications, which like nitrogen fertilizer, are best done after soil cools to under 50 degrees F.
