Does anyone know where I can get information on current soil temps (other than out my back door with a thermometer)? I looked all over google using terms like "Michigan current soil temps", and couldn't find anything. I tried using Michigan State U for it also, but to no avail. If anyone has a site that would perhaps keep reasonably up to date data like this (even better at different depths), that would be cool. Thanks ahead of time.:weightlifter:

Try this soil temp map. Only problem is it has not been updated...it says current through July 10! What? Don't they know how important soil temp is for new seeding and for fall crop seeding like wheat?

Maybe they just forgot for a few weeks.

Yeah,...that was the first one i saw...But then no way to see an update of it. Jeez,...you would think that SOMEone like a university would have a page for this.

I use gddtracker.net and wunderground.com (Weather Underground) but neither one has soil temps. I spot check it myself when I want to know. Right now I have some turf covers out so I check the temperature difference underneath and outside them a couple times a week.

Michigan Automated Weather Network has soil temperature information.

Go to http://www.agweather.geo.msu.edu/mawn/
-then click on a reporting station on the map
-Under "Pregenerated Data Reports" click on either of these:
-hourly data, then look in soil temp column for extensive (hourly) data for most recent 3 days. It says Temp is taken at 2" depth on bare soil.
-or click on daily data for soil temp high-low measurements for current and previous month

Thanks Foreplease--very helpful--thanks MAWN.

Ground truth data. I used a soil thermometer at about 2 depth today (Nov 2, 2009)under grass--got a temp of about 48 degrees.

I also talked to a local supplier and seed expert. He is not a believer in "dormant seeding" . Suggested wait until spring.
