Good Morning!!!!!!

hey Dotch.....any info o frost depth???????

Yes & soil temperature. Frost depth at the SROC Experiment Station in Waseca was 23" under bare ground as of Feb. 3rd. Soil temperature is something being talked about as well. I know some kinda think that if it's frozen, it's 32 degrees but the soil temp gets colder than that, just like air temperatures. When soil temps get down to 20, it starts impacting pests such as western corn rootworms. The mortality increases with the duration and drop in temperature from there. Some of the soil temps especially as we move north have been well below that especially at the 2" due to light snow cover or complete lack of it like around here. The one positive about the wet weather last spring was it raised hob with rootworms after they hatched. Part of it was saturated soils lacked oxygen and many of them suffocated. There may have been disease organisms afoot as well, thinning the herd. Add in some sub-20 degree winter soil temps and any eggs laid by those that survived will suffer increased mortailty.

Here's a link to a bunch of data for your perusal. Not a fan of the new NDAWN system they've gone to as far as weather data at the Experiment Stations. Not very user friendly. A lot of crap to wade thru when you just wanna cut to the chase.
