Weather will affect corn, soybean crops for Missouri farmers

COLUMBIA - Unusual weather conditions over the past several months will have an adverse effect on crops across the state of Missouri, according to one MU professor. 

Bill Wiebold, University of Missouri Extension agronomist, said the unusually rainy spring combined with lower-than-average rainfall in August spells trouble for corn and soybean farmers in an article he published in Ag Professional magazine.

"We had hoped that the unusually wet spring this year would be followed by above average precipitation in August," Wiebold wrote in the article. "Unfortunately, that is not the scenario that has occurred in much of Missouri in 2015."

According to the article, wet weather means the roots of the crops are smaller and aren't as healthy. Then, when the weather gets hot like Missouri experienced in August, the weaker roots aren't able to absorb enough water or nutrients. According to Wiebold, this means farmers will most likely have fewer crops to harvest.

"A scenario that is most detrimental to gain-crop yield is a wet spring followed by dry weather during grain filling," Wiebold wrote.

According to weekly USDA crop reports for Missouri, the state had 2.46 inches of rain the last week of May, 1.44 inches above normal. During the last week of August, the state had .19 inches of rain, .61 inches below normal.

According to the Wall Street Journal, corn prices have risen nationally after the USDA reduced its estimate for corn production this fall, citing adverse weather in the Midwest.
