Understanding the types of wind erosion and their effects can help farmers take steps to prevent it from happening.

The Earth's land surface is dominated by sloping landscapes. Every year, soil erosion laterally distributes on the order of 75 Gt of topsoil (Berhe et al. 2007). The coupled biogeochemical cycles of ...

With soils rich for cultivation, most land in the Midwestern United States has been converted from tallgrass prairie to agricultural fields. Less than 0.1 percent of the original prairie remains. This ...

Take a handful of soil and hold it up to your nose. That fresh, earthy aroma is organic matter, part of which is carbon. What you can smell is the whiff of a solution for dealing with climate change.

Soil erosion is a major worldwide threat to agro-ecosystem sustainability and land productivity. Fallout radionuclides and stable isotopes are used to measure magnitudes and sources of soil erosion, ...

Climate change is increasing temperatures and causing heavier rainfalls across the country. Scientists are studying how these changes will affect different natural resources including the soil ...

Human activity causes 10 times more erosion of continental surfaces than all natural processes combined, an analysis by a University of Michigan geologist shows. ANN ARBOR, Mich. --- Human activity ...

In the countries of the South, erosion is a process often exacerbated by the high rainfall that affects these regions during the wet season. Recent research conducted in Mexico has led to better ...

The thin layer of topsoil that covers the planet’s land surface is the foundation of civilization. This soil, typically 6 inches or so deep, was formed over long stretches of geological time as new ...
