Louisiana’s recently planted corn crop appears to be the biggest agricultural casualty from widespread flooding across the state.

Dan Fromme, LSU AgCenter Extension corn specialist, said corn farmers had planted roughly 30,000 acres in an eight-parish area of north Louisiana, or about 8 percent of the state’s total corn acreage in 2014.

Corn seed and seedlings will suffer from being flooded because of the lack of oxygen in the water-logged soil, said Dr. Fromme, who is based at the Dean Lee Research and Extension Center near Alexandria.

Whether fields will have to be replanted is uncertain, according to Fromme. “You really won’t be certain for four to five days after the water subsides.”

Replanting could cost roughly $140 an acre for seed and $100 an acre for fertilizer in addition to fuel costs. “And it will be hard getting seed to replant,” Fromme added.

Richard Letlow, LSU AgCenter Extension agent in Ouachita Parish, said 15 to 20 percent of the corn crop in Ouachita and Morehouse parishes had been planted. Excessive moisture will complicate corn planting. “It is early in the planting window. However, wet conditions will push all corn planting toward the back end of this planting period.”
