Other expressions of affection may have smelled sweeter, but don't tell that to Carole Kleis.
According to a recent report from the Associated Press, Kleis' husband Dick spelled out a birthday wish to her in an Iowa field. But rather than mow out a message with a tractor, the Iowa farmer spelled out his missive in manure.
After four loads of liquid manure and about three hours of labor with some agricultural equipment, Dick's message to his wife spelled out "HAP B DAY LUV U" in a field near their home in Zwingle, located in the eastern part of the state.
"I was going to put a heart out there after the happy birthday, but I ran out of manure," Dick Kleis said.
Based on figures from the Iowa State University Extension, the AP noted that Dick used more than 123,000 pounds of poop in order to convey the birthday greeting for his wife.
Though birthday wishes may be one way to get manure into a field, there are other things to consider when using it to help grow crops. For example, the Iowa Department of Natural Resources notes that the state's law requires producers fill out a manure management plan, which can help regulate nutrient concentrations.
