What these dates mean in South Dakota

Planting usually runs about 52 days, from Mar 31 to May 21.

That start date is close to the middle of the 10 places in this data set that report spring wheat planting dates (Mar 29).

Harvest usually runs about 41 days, from Jul 20 to Aug 29.

From the start of the planting window to the start of the harvest window is about 111 days in South Dakota, a rough guide to how long the crop occupies the bed or field.

Frost-date caveat: these are published ranges for South Dakota. A northern or high-elevation site will run later than a southern or low one, and a cold wet spring can push planting past the window. Frost dates and local conditions vary; NASS state-level usual dates from 20-year progress data (Oct 2010 edition), begin ~5% and end ~95% complete. Check your last spring frost and soil temperature, and confirm with your county extension office.
