Ongoing weather concerns will likely mean many Arkansas rice farmers will need to dole out nitrogen fertilizer throughout the growing season, rather than apply it prior to flood this year.
Jarrod Hardke, extension rice agronomist for the University of Arkansas Division of Agriculture, said that after winter-long drought conditions through much of the Delta, farmers are hoping to make up for lost time with late-spring rains without being completely gully-washed.
“We’re grateful for the rainfall, but it’s coming at a time when we need to be applying herbicides to clean up some of our weeds before going to flood,” Hardke said. “Our most efficient method of nitrogen fertilization is putting it on dry ground before flood. That’s our ideal scenario, and we’re getting very narrow windows to accomplish much of that for the crop.”
The past several weeks, Hardke said, have alternately been marked by very wet conditions and, when dry, high winds. In addition to nitrogen, the conditions also make it difficult to apply herbicide, he said.
According to the U.S. Department of Agriculture’s National Agricultural Statistics Service, 100 percent of Arkansas’ projected rice acreage — which Hardke now estimates at about 800,000 acres — had been planted by the last week of May, and 95 percent of that had already emerged. In the weeks that have followed, significant rain events have marked the weekends across much of the state.
