Land Use: County Data

Iowa’s counties exhibit diverse agricultural patterns shaped by crop productivity, land use practices, and rotational strategies. This data provides a detailed view of historical and recent trends in crop yields, planting ratios, and farmland distribution across the state. It supports decision-making in agriculture, conservation, and land management.


Crop Yields

Annual and 5-year average yields for corn, soybeans, oats, alfalfa, and hay reflect productivity shifts and regional performance differences.
