Soil scientist and blogger, Andrea Basche, in the Black Hills of western South Dakota. In the 1960s, soil scientists uncovered the fingerprint of the soils in the region to be a result of the mixed prairie and forest vegetation. Interestingly, this unique pocket of forest shows up on national maps depicting a different ecoregion of vegetation, climate and soils. Credit: Aaron Price
Traveling? Look down for the changes right below you!
If your summer has included travel, you may have noticed a difference in the soil beneath your feet. The Soil Science Society of America (SSSA) July 15 Soils Matter blog explains why different areas have such different soil.
“The color and texture of a soil (and many other properties that relate to soil’s ability to produce food) are intertwined with that specific location,” says blogger Andrea Basche, USDA-NIFA. There are five local elements that influence a soil: climate, organisms, relief, parent material, and time.
“All these factors taken together are why I like to describe soil as the living crust of the earth,” Basche says.
Basche notes that soil can even change dramatically within a state. “Western Washington has frequent rains; eastern Washington has much less rainfall. Western Washington has a quite varied relief, with mountains and even a volcano. Eastern Washington is much more flat. So it’s no wonder that the soils in those regions are different as well.”
