The U.S. corn crop is maturing quickly, according to the United States Department of Agriculture’s (USDA) latest Weekly Weather and Crop Bulletin.

USDA reported that 12 percent of the total corn crop is mature. That number is up from 6 percent last week but still shy of the five-year average at 18 percent.

On a state level, North Carolina has the largest percentage of mature corn at 83 percent, up from last week’s 72 percent.

The corn crops in South Dakota, Pennsylvania, Minnesota and Michigan are only 1 percent mature.

USDA also ranked 48 percent of the U.S. corn crop as good.

Soybeans

11 percent of the total soybean crop has dropped its leaves, according to the USDA’s report. That number is up from 6 percent last week.

The soybean crop in Louisiana has dropped 64 percent of its leaves, which is the highest state among the 18 states recorded.

None of the soybean crop in Wisconsin has dropped its leaves, according to the USDA. At this time last year, 5 percent of the state’s soybean crop had dropped its leaves.

USDA ranked 50 percent of the total U.S. soybean crop as good.

Wheat

Farmers have harvested 89 percent of the U.S. spring wheat crop.

That number is up from 76 percent the week before and up from the five-year average of 78 percent.

USDA took Trumps comments that China would buy more U.S. soybeans seriously and headline news that the U.S./China trade truce would be extended when Trump/Xi meet in the first week of April was a BIG WIN for soybeans this week! 2026 “Mini” U.S. ethanol boom thanks to 45Z + China’s ban of phosphates from Feb. – August of 2026 will not help lower fertilizer prices anytime soon! 30 mmt of Chinese corn harvest is of poor quality and maybe a technical breakout in wheat futures.
