“If you were unable to get manure applied this fall, or didn’t get as much applied as you normally do, it is essential to consider the impact it will have on manure management on your farm this winter,” says Dan Andersen, an Iowa State University Extension ag and biosystems engineer. “It’s especially important for farmers to ensure that adequate storage for manure is available for winter months.”
He noted that it is crucial for farmers to get their storages pumped down so that they have adequate capacity to make it through critical storage periods, such as winter. “Confinement feeding operations must retain all manures produced by the farm during periods between land applications,” Andersen said.
“We want to remind farmers that the law prohibits manure application from these operations between Dec. 21 and April 1 if the ground is snow-covered, unless the manure can be properly injected or incorporated,” says Andersen. He noted that starting Feb. 1, manure application from these operations is also prohibited on frozen ground.
