Soil Temperature Part 2: How do No-Till temperatures catch up to Conventional Till?
Channel: USDA NRCS South Dakota
Date: 2017-09-12

In our previous video we saw that by the end of the season, there is no difference in the number of heat units seen by a conventional versus a no-till soil.  In fact any differences in cumulative heat units between the two systems disappears by the first week of July.  In this video, SDSU’s Anthony Bly explains how that happens by examining the side-by-side temperature comparisons between a no-till, and conventional till system near Vermillion, South Dakota.  In the latter part of the season (after July 1), we also see that in no-till soils maximum temperatures are consistently cooler and minimum temperatures are consistently warner than conventional till soils.  The NRCS Eric Barsness discusses this and tells us why it’s a good thing.
