Soil erosion can be minimized/controlled by afforestation, use of timber alternate, controlling the flow of water by growing cover crops, managing agricultural intensification and urban sprawl. There are two categories of erosion—natural erosion and accelerated erosion. Soil erosion occurs when soil is removed through the action of wind and water at a greater rate than it is formed SOIL The soil covering the surface of the earth has taken millions of years to form and we must learn to respect it.

Describe types of physical weathering" 4. There are various methods of remediation but, most of these methods are unable to restore the environment to its proximal or original state to achieve the desired outcome. Chemically, reclamation of saline soils is also an option involving organic and inorganic amendments which can make salt-affected soils capable of giving a sustainable production. However, study forecasts pattern of soil erosion in the area while hypsometric study shows that the watershed is at a mature stage of erosion having low erodibility. Erosion also leaves large holes in the earth, which can weaken buildings and even cause them to collapse. 1. This chapter will discuss both the individual contribution of plants, fungi and bacteria in the rejuvenation of contaminated sites as well as their interactive effect on the restoration of polluted sites. A typical coastal area like the Tuticorin Coast has been taken up in this p, In this project, we, the investigators, aimed to study the hydrogeological and geochemical factors that are responsible for the formation of scales by groundwater and also in creating incrustations. Although soil erosion is a natural process, it is often accelerated by human activities, for example by the clearing of vegetation, soil tillage or overgrazing. This project would increase the understanding of the water-borne soil erosion directly related to river systems and the GIS combined RUSLE model. 5-5 stars based on 95 reviews Case study presentation format for interview: how to cite a book in a research paper mla.

Raindrops hit bare soil with enough force to break the soil aggregates. Environmental restoration is a process that aims to enhance the rejuvenation of contaminated environmental media. T value = Tolerable erosion equilibrium between soil gains and losses.” continuous cropping and maintain soil productivity without requiring additional management inputs.” • T ranges from: 1-5 t/ac/yr < 25 cm = 2.2 t/ha/yr > 152 cm = 11.2 t/ha/yr “Maximum soil erosion loss that is offset by the theoretical If we want to save our soils, we need to understand the different types of erosion that can occur. Compare/contrast 3 types of weathering" 3. Interestingly, phytoremediation, which is a biological process, not only restores the environment to green but can also adopt a variety of mechanisms to reduce the contaminations. Soil erosion is a major environmental problem confronting land and water resources in South Africa. 0000010088 00000 n Introduction: Soil Erosion Soil erosion is the washing or blowing away (by wind or water) of the top layer of soil (dirt). Water and wind are estimated as the main agents that arouse the appearance of this phenomenon, especially in arid zones. The Soil Management Plan described here uses a more detailed assessment to identify varying degrees of risk of both runoff or soil wash and erosion. Thus, modeling soil erosion requires a multidisciplinary approach among soil scientists, crop scientists, hydrologists, sedimentologists, meteorologists, and others. Thanks are due to DST and my colleagues. In a healthy soil ecosystem, fungal filaments and exudates from microbes and earthworms help bind soil particles together into stable aggregates that improve water infiltration, and protect soil from erosion, crusting, and compaction. 0000003400 00000 n roject and a detailed study has been completed in 1989 itself.
