In these areas, protecting against soil erosion through sustainable land management can solve a multitude of problems. The smaller soil particles are easily carried by water or wind, resulting in soil erosion. When the soil is dense and of low porosity, roots have a harder time digging down through compacted layers to take hold. history notes 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. Also, the canopy of the forests lowers the impact of the falling water on the ground. Scientists estimate that in the Midwest, home to.

A drier soil is more easily eroded by the wind, as you can imagine through the imagery of dust storms in deserts and other dry regions. To do this they turn to the process of tilling, where they use machinery to turn the soil over. Company on the podcast, to listen to the episode press play below: Most crops that we produce globally are annuals. dont need to be re-sown every year, meaning the soil is far less frequently Most existing studies have focused on one influencing factor, namely slope gradient or rainfall intensity, for slope erosion and nutrient loss, but the joint effects of the two factors have rarely been researched. Nonburrowing animals such as mites, springtails, and fly larvae will have an especially difficult time living in compacted soil.

As a growing human population cuts down forests and transforms natural landscapes into fields for agricultural crops and pasture land, the sustainable use of the worlds natural resources is becoming increasingly important. Soil. After the topsoil is eroded because of the loss of vegetation, the next layer that will be eroded is the seed bank within the soil. Mudslides not only affect structures supported by the soil but also buildings and roads that are in the path of slides. Pesticides and other chemicals can get trapped in soil, polluting streams and rivers as the soil breaks apart. As erosion wears down the soil and the land, its ability to support plant life decreases. Scientists have long identified humans as the primary agents altering the shape of the Earths surface. All rights reserved. It is because, during construction, vegetation is often cleared off, leaving the land bare and susceptible to water and wind action.
