The ground temperature fluctuates seasonally, like the surface temperature. The fluctuation amount decreases with depth, to a negligible amount at about 30 feet. The extremes lag the surface times by weeks to months. The envelope of the extremes is the "trumpet curve".

Nov 6, 2014 · The featured chart presents yearly timeseries of four inch depth soil temperatures from the ISU AgClimate (now ISU Soil Moisture) station at the AEA Ames AgFarm. The black line represents the simple average of all the yearly lines. As with air temperatures, soil temperatures have been on the warm side of average recently. Young plants, however, are sensitive to direct sunlight and need to be placed in partial shade during development. Temperature affects the rate of seed metabolism and most have a temperature range within which they germinate. The optimal temperature is between 70 to 80 degrees Fahrenheit or 21 to 26 degrees Celsius.

The general recommendation is to avoid glyphosate applications when evening temperatures fall below 40°F. 2,4-D is somewhat more consistent than glyphosate during cool periods (assuming sensitive weeds), and thus addition of 2,4-D LV ester can enhance burndown performance in certain situations. Burndown herbicides that interfere …

Germination process and soil temperature. Seed absorbs about 30 percent of its weight in water; temperature does not affect that process. But temperature does affect growth of both the radicle (first root) and coleoptile (shoot). With soil temperatures below 50 F, seeds readily absorb water but do not initiate root or shoot growth.Changes in the Earth's temperature and the impact that it has is explained in this article from HowStuffWorks.
