A fast spreading, crop destroying weed may be coming to the farms near you.

Palmer amaranth, which has plagued southern farms for decades, has been marching across the Midwest. It can decimate a crop. It can withstand many common herbicides. And it can cost farmers millions.

Roger Hargrafen, a farmer in Muscatine County, Iowa, is on the front lines in the battle against Palmer amaranth. His is one of four Iowa farms confirmed as having it.

Ecologists in Nebraska are trying to find out what the Great Plains looked like when homesteaders settled there in the 19th century. To do that, they’re working with a team of archaeologists and historians dissecting a sod house, a house built out of bricks cut from dirt.

Larry Estes has had a sod house in his backyard in Gates, Neb., for as long as he can remember. He never really thought anything about it until a year ago when a repairman asked him about it.

Join Talk of Iowa for a talk with Douglas Tallamy, Professor and Chair of Entomology and Wildlife Ecology at the University of Delaware. He says “We need to change the way we interact with nature; it should not be segregated,” and that living with nature can be very rewarding. Tallamy says that Americans use plants that are mostly from Asia as decorations.  The result is a reduced biodiversity in the places we live, work, and farm.  Hear from Tallamy  about how we can connect habitats by reinstalling native plants.
