Joe Mullins, from the USDA Natural Resources Soil Conservation Service office in White County, is shown presenting a program about soil erosion to the agri-science students at the White County High School, on March 2, 2017.
The impact of losing fertile soil is bad enough for the farmer, but the impact carries fertilizer and pesticides into local waterways making soil erosion everyone’s concern.
Half of the topsoil on the planet has been lost in the last 150 years. Soil conservation is one of his biggest concerns, since cultivated soils erode slowly enough to be ignored in a single lifetime, but fast enough over centuries to curtail entire civilizations. Soil is the earth’s fragile skin that anchors all life on earth.
The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. Sustainable land use can help to reduce the impacts of agriculture and livestock, preventing soil degradation and erosion and the loss of valuable land to desertification.
The health of soil is a primary concern to farmers and the global community whose livelihoods depend on well-managed agriculture that starts with the soil beneath our feet. While there are many challenges to maintaining healthy soil, there are also solutions and a dedicated group of people, including agencies like USDA Natural Resources Conservation Service of Tennessee are working to educate, innovate and maintain the soil from which biodiversity springs.
