Land resource units are geographic areas, often extending for thousands of acres, that are characterized by common patterns of soil, climate, water resources and the use of the land. Land resource units are the basic elements from which the USDA Soil Conservation Service (SCS) determined Major Land Resource Areas (MLRA). MLRAs are geographically related land resource units. The USDA Soil Conservation Service identified these and also their next higher grouping, Land Resource Regions, based on the same but broader factors.
