Corn-planting activity has picked up in some parts of the country, but major states such as Iowa and Illinois are still lagging behind.  

The USDA’s latest Crop Progress report, released on Monday, some farmers were able to get into the fields before rain and snow slowed planting to a crawl. This week the nation’s corn planting progress was reported at 12 percent, 7 percentage points higher than last week’s report and the largest gain in planting seen yet this year.

All states now have at least some corn in the ground.  North Carolina (89 percent) and Texas (70 percent) still have the highest percentages of planted corn. 

But the two leading corn states, Illinois and Iowa, only have 7 percent and 8 percent planted, respectively.

Seven states have reported emerged corn, including Kansas (2 percent), Kentucky (12 percent), Missouri (12 percent), North Carolina (70 percent), Pennsylvania (1 percent), Tennessee (30 percent) and Texas (61 percent).

Nationally, 3 percent of corn has emerged.

The report also showed that soybean planting has reached 2 percent.  Read the full Crop Progress report.

On Monday corn futures fell 3.7 percent, their biggest drop in more than a month, on forecasts calling for warm and dry weather next week. Soybeans also fell on Monday.

Despite the slow start, corn planting will likely speed up next week as a drier, warmer pattern persists.

"I have seen a lot of planters in the fields today, talked to a lot of guys who are rolling," said Brian Hoops, president of Midwest Market Solutions told Reuters. "Everybody knows that we could have a pretty decent window (of good weather) here. It all looks pretty good for planting."
