The temperature of the air near the surface of the Earth is measured at meteorological observatories and weather stations, usually using thermometers placed in a shelter such as a Stevenson screen—a standardized, well-ventilated, white-painted instrument shelter. The thermometers should be positioned 1.25–2 m above the ground.
For germination in small grains, the recommended 3-day average soil temperature is 34-36 °F for spring wheat and 40 °F for oats. For corn, germination occurs at 50 °F but planting often occurs earlier when soil temperatures are lower. A corn field planted when the 3-day average soil temperatures are greater than 50 °F will typically emerge ...Mar 27, 2012 · 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. This application dynamically generates many types of graphs.

Condensation. Objects near the ground cool rapidly at night through emission of infrared radiation. The ground and objects near the ground are often much cooler than the surrounding air. Air in contact with these objects cools by conduction, eventually reaching the dew point. As water vapor condenses on these surfaces deal) begins to accumulate.Reduce heat for soybeans and limit air drying temperature to 130°-140° F. for commercial beans and 100°-110°F. for seed beans. Retention time in the heat section of dryers should be less than 30 minutes. To avoid differences in moisture levels from top to bottom in batch-in-bin dryers, use shallow batch depths of 2 to 3 feet.Figure 1: Observed and projected changes (compared to the 1901–1960 average) in near-surface air temperature for Iowa.Observed data are for 1900–2020.
