Soils Theme Definition: Depicts the geography and attributes of the many kinds of soils found in the landscape at both large and small map scales. A Living dynamic resource providing a natural medium for plant growth and habitat for living organisms, soil recycles nutrients and wastes, stores carbon, and purifies water supplies. Soil has distinct layers (called ‘horizons’) that, in contrast to underlying geologic material, are altered by the interactions of climate, landscape features, and living organisms over time. |
