This free Practical Farmers of Iowa field day visits Tom and Robin Cummings at TRC Farms near Redfield, Iowa. At this field day, Robin and Tom will showcase their seed-cleaning and straw-baling operations. They harvest and clean rye for cover crop seed and produce up to 40,000 square bales per year to sell at Bomgaars and Tractor Supply stores in their area. They're also eager to share how teff grass is finding its place in their rotations.
