Weather Station Information

line

Thanks to the Commercial Agriculture Program and the Atmospheric Science Unit the automated weather station was installed at the Greenley Research Center in early September 1994.

Soil Temperatures
One of the unique features of the weather station is to record soil temperatures at the two inch depth for corn, soybean, wheat residue, and bare soil. Find below a table with soil temperature recordings at the two inch level for bare soil and corn residue starting April 1 and ending April 30.

Soil temperatures are usually coolest between 6 a.m. and 8 a.m. The highest soil temperatures occur between 4 p.m. and 6 p.m. The average soil temperature will be higher than those read in the morning.

Ideal soil temperatures for good corn germination should be 50 degrees F at the two inch depth of soil measured between 8 a.m. and 9 a.m. Minimum soil temperatures for good soybean germination should be 55 degrees F at the same depth and for grain sorghum (milo) they should be 60 degrees F at the same depth.
