Iowa is famously known for its livestock and farming industry. This leads to another claim to fame, according to calculations done by a University of Iowa research engineer, which some might say stinks: the state produces more fecal matter, per square mile, than any other in the country.

Iowa placed first on the list, followed by Delaware, Wisconsin, Nebraska, and Pennsylvania.

Chris Jones, a research engineer in the water quality monitoring and research division at the University of Iowa's IIHR Hydroscience & Engineering department, posted the results of his calculations on his blog last week. It determined the total waste produced by humans and livestock animals divided by the total land area of a state.

Iowa's humans and livestock produce as much fecal waste per square mile as a human population density of 2979 people. This is just a little bit over the population density of Iowa City, but over the entire land mass of Iowa, according to Jones.
