Describe the pattern of soil degradation in the United States. How does the severity of soil degradation in the southeast compare with that in the plains states from Texas and the Oklahoma panhandle up through Kansas, eastern Colorado, Nebraska, and Iowa to the Dakotas

Abstract

Soil can be degraded by several natural or human-mediated processes, including wind, water, or tillage erosion, and formation of undesirable physical, chemical, or biological properties due to industrialization or use of inappropriate farming practices.

The more intense the farming, and the longer a region has been farmed, the worse the soil degradation.

the only plants classified as non-seed producers are b) moss, fern, and liverwort!
