U.S. corn and soybean conditions slipped for the second week in a row last week as excessively wet weather hurt crops in parts of the Midwest and hot, dry weather stressed the crop in the Delta/Southeast.
Corn development remains ahead of schedule with 7% of the crop reported silking, compared with 4% a year earlier and the five-year average of 5%.
Soybean conditions were rated 67% good/excellent as of Sunday, down from 69% a week earlier and 68% a year earlier.
Soybean planting progress rose 4 percentage points to 97%, which was on par with the five-year average, with emergence up 6 points to 93%, also on par with average.
USDA reported that 9% of the U.S. soybean crop was blooming, up from 4% a week earlier and on track with the five-year average of 9%.
In the top producing state of Iowa, the good/excellent rating for the corn crop fell 3 percentage points on the week to 72%, down from 81% a year earlier.
The portion of the Iowa soybean crop rated good/excellent also fell 3 percentage points on the week to 66%, compared with 78% a year earlier. Some 10% of the Iowa soybean crop is now rated poor/very poor.
Surplus rains are leading to widely varying crop conditions across Iowa. "Some fields have areas completely drowned out by standing water and sections turning yellow with stunted growth; meanwhile portions on high ground which drain well are thriving," NASS said.
The biggest deterioration in crop conditions came in the Delta/Southeast where hot, dry weather took a toll on crops.
In Arkansas, soybean conditions deteriorated to 50% good/excellent from 61% a week earlier due to moisture stress, while the North Carolina corn crop rating plummeted to only 40% good/excellent from 63% a week earlier.
