Agroecoregions and Soil and Water Quality
Agroecoregions of Minnesota
Minnesota has 39 agroecoregions. Each agroecoregion is associated with
a specific combination of soil types, landscape and climatic features,
and landuse. Agroecoregions are units having relatively homogeneous climate,
soil and landscapes, and land use/land cover. Agroecoregions can be associated
with a specific set of soil and water resource concerns, and with a specific
set of management practices to minimize the impact of land use activities
on soil and water resource quality.
