Here are some charts comparing the soil temperatures at 2 inches deep in the row where the residue was cleared off with row cleaners between two fields. They were treated the same except field A was planted 5/2/2012 and field B was planted 5/10/2012. They were both were soybeans in 2011. In the charts the red bar is from field A and the green bar represents the temperatures from field B.
The first chart shows the daily weighted average soil temps.
The rest of the charts compare the daily(24 hour) temps on a few selected dates.
The first three pictures are from field A and last two from field B.
What has me puzzled is why A starts out cooler than B over night then is the opposite durning the day .
