Location of Studies
We had field studies at dryland farms in Hill, Fergus, and Gallatin County, Montana. Hill County lies within Montana's largest wheat producing region, referred to as the "Golden Triangle". This region annually seeds 2.2 million acres of wheat and is characterized by a semi-arid climate with 12 to 15" of annual precipitation. Hill County is one of the drier regions of the Triangle. Wheat-fallow is the dominant cropping system with most farms managed as no till.
