Soil temp iowa

Soil temperature is one of the most important factors to guide planting decisions. The rule of thumb is to wait until the upper 4 inches reach at least 50 degrees, with a warming temperature trend in the forecast. One way to track soil temperatures across Iowa is by using the soil temperatures map compiled by the Iowa Environmental Mesonet at Iowa State University.

In irrigated fields, smaller row spaces are preferred (15-18 cm - 5.9-7 in). Seeding of winter wheat generally takes place at a depth of 2-5 cm (1-1.6 inches). When temperature and soil moisture are at favorable levels, seeds can be sown closer to the surface (2 cm) to accelerate emergence. Seeds of dwarf varieties can be sown at a smaller depth.rainfall totals in the 0.25 to .50-inches range was found from west central to southeast Iowa.

Grass stops growing in the fall when temperatures consistently remain between 40-50 degrees Fahrenheit (5-10 degrees Celsius). While grass can actually grow right down to freezing air temperatures (albeit slowly), it grows much better above the 40-50 degrees Fahrenheit range. Keep in mind that the soil doesn't instantly adjust to the same ...Darker soils will absorb heat at a faster rate than lighter-colored soils. — Higher levels of crop residue on soil surfaces can result in slower soil warming due to increased soil moisture.
