South Dakota’s corn crop remains well behind normal rates of maturity after another short week of fieldwork because of more rain and wet conditions, according to the weekly crop progress report from USDA’s South Dakota National Agricultural Statistics Service based in Sioux Falls.

Only 4.2 days were fit for fieldwork in the week ending Sunday, July 21, NASS reported on Monday. That continues a remarkable trend this season of less than normal time for farmers to get their fieldwork done due to rain, mud and floods. It's led to late crops in most fields.

Only 9% of the state’s corn crop was in the silking stage (ask your parents what that means), compared with 50% by now in the five-year average pace and 72% a year ago. But 58% of the crop is in good or excellent condition, with 32% rated fair and 10% in poor or very poor shape.

The soybean crop is also blooming good on 45% of the state’s acres, but that’s behind the five-year normal pace of 65% by now, the NASS reported. The soybean crop was rated good or excellent on 47% of the fields, fair on 42% and poor or very poor on 11%.

Winter wheat, nearing harvest time, was rated good or excellent on 65% of the acres, fair on 28% and poor or very poor on 7%.

Spring wheat is behind the average pace some, too, with 86% of the crop headed out, compared with 98% by this time in the five-year average.

The crop is rated good or excellent on 70% of the fields, fair on 27% and poor or very poor on 3%.

Pastures and ranges are rated good or excellent on 80% of the acres (50 and 30, respectively), fair on 15% and poor or very poor on 5%.

Topsoil and subsoil moisture is adequate on 68% of the ground, short on 1% and surplus on 31%.
