Soil: more than meets the eye
Oct. 3, 2016 - Are you unaware of what is underfoot? Soil is all around us and easy to ignore. However, locked inside is a dynamic ecosystem of amazing complexity. The Soil Science Society of America (SSSA) October 1st Soils Matter blog post explains how soil’s physical, chemical, and biological activities make soil more than dirt.
Blog author Mary Tiedeman, a scientist at Florida International University, explains. “All soils are comprised of a few basic ingredients. These include minerals, organic materials (both living and dead), and pores filled with water and gas. When combined and subjected to external forces (such as gravity and climate), soil particles react with one another.”
“The importance of these soil particle reactions is tremendous! They contribute to the overall health and functionality of soil systems. In the short term, physical, biological, and chemical activities work in tandem to squeeze soil materials together, pull them apart, and transport them to different locations. They contribute to nutrient cycling and to the creation and decomposition of soil organic matter. Over hundreds, thousands, or millions of years, soil processes even contribute to shaping entire landscapes.”
Scientists are working to understand the many processes at work in soils. By learning more we can be better stewards of this precious resource for future generations.
