Is it profitable to farm prairie potholes?
By Wallace Farmer
Prairie potholes are usually small in size, but when farmed, these perennially wet spots on the landscape can have outsize implications for the environment and farm profitability.
The Prairie Pothole Region extends from Canada south and east, and through parts of Montana, North Dakota, South Dakota, Minnesota and Iowa. In Iowa, many potholes are found in the Des Moines Lobe, an area that spans the north-central part of the state, ending around the Polk-Story county line and the vast majority of them are farmed.
These areas in crop fields habitually yield poorly and drag field yield averages down, and they are prone to nutrient loss and leaching, raising questions about the benefits of continuing to grow corn and soybeans in them. For the full story, click here.
