IOWA AHEAD: Iowa is ahead of the U.S. in crop ratings. Only 37% of the U.S. corn crop is in good-to-excellent condition, and only 36% of the nation’s soybean crop is good-to-excellent.

Iowa corn crop rated 78% good-to-excellent

Latest USDA survey shows 74% of Iowa’s 2017 soybean crop is good-to-excellent.

Warm and windy weather with spotty thunderstorms prevailed across Iowa during the week ending June 18, according to the latest weekly survey by USDA’s National Agricultural Statistics Service. Those isolated storms left some farmers assessing crop damage from strong winds and hail. Statewide there were 5.2 days suitable for fieldwork. Activities for the week included cutting hay, spraying herbicides, sidedressing nitrogen and replanting.

Statewide, topsoil rated 5% very short, 22% short and 71% adequate. Subsoil moisture rated 3% very short, 15% short and 79% adequate.

Corn, soybean crops catching up
How are crops in northwest Iowa? “In general, looking good — both corn and beans,” says Paul Kassel, Iowa State University Extension field agronomist at Spencer. “We had a bit of a rough start in April with planting delays due to too much rain. And in parts of May we also had some planting delays due to wet weather. Wet weather kept us pretty much out of the field from mid-May to Memorial Day. Then it turned hot and dry in June, and we got the remainder of the acres planted.”

Then everything started growing. “In general, as of today, June 19, our corn and soybean crops are looking good,” says Kassel.

Summary of Iowa crop conditions
The weekly survey results as of June 18 show topsoil moisture for Iowa rated 5% very short, 22% short, 71% adequate and 2% surplus. That’s the statewide average. Southwest Iowa reported the highest levels of topsoil moisture with 96% adequate to surplus. Subsoil moisture levels for the state average rated 3% very short, 15% short, 79% adequate and 3% surplus. Only the northeast and southwest corners of Iowa saw an increase in subsoil moisture for the week. Many reports from crop observers mentioned the need for timely rain.

The survey showed 78% of the state’s corn crop is now rated in good-to-excellent condition. Soybean emergence reached 92%, five days behind last year but four days ahead of average. Soybean condition rated 74% good to excellent. Oats headed reached 67%, four days behind last year. Oat condition rated 77% good to excellent.

The first cutting of alfalfa hay reached 94% complete, and a second cutting has begun in many areas. Hay condition remained 83% good-to-excellent. Pasture condition decreased slightly to 69% good-to-excellent. Some livestock stress was reported as a result of the heat.
