Introduction The word "erosion" is derived from the Latin "erosio", meaning to "to gnaw away". In general terms soil erosion implies the physical removal of topsoil by various agents, including rain, water flowing over and through the soil profile, wind, ice or gravitational pull.
Soil Erosion. It is a process in which the top fertile layer of soil is lost. Due to soil erosion, the soil becomes less fertile. The top layer of soil is very light which is easily carried away by wind and water. The removal of topsoil by the natural forces is known as soil erosion. Causes of Soil Erosion
Soil erosion is the displacement of the upper layer of soil, it is one form of soil degradation.This natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, air (wind), plants, animals, and humans.
Soil erosion is the movement of soil from one place to another and may be caused by wind, water or human activities. The process can occur naturally over a long period of time, or it can occur quickly with unusual weather events or excessive vegetation removal. Erosion affects both farmers and home ...
Chapter 3 Soil Erosion and Its Controls - Chapter 3 Soil Erosion and Its Controls 3.1 Introduction Soil erosion is the detachment and removal of soil particles from the soil mass by water or wind. 3.1 ... | PowerPoint PPT presentation | free to view
Soil Erosion Causes and Effects: Introduction Soil erosion is one form of soil degradation along with soil compaction, low organic matter, loss of soil structure, poor internal drainage, salinization, and soil acidity problems. These other forms of soil degradation, serious in themselves, usually contribute to accelerated soil erosion.
Students will hypothesize the effects of soil cover on soil erosion and conduct an experiment to measure the level of soil erosion in various cropping situations. Introduction This lesson is the first lesson in a series of four lessons centered around soil erosion.
Soil erosion reduces cropland productivity and contributes to the pollution of adjacent watercourses, wetlands and lakes. Soil erosion can be a slow process that continues relatively unnoticed or can occur at an alarming rate, causing serious loss of topsoil.
Soil and Agriculture: Lesson 3 - Soil Erosion ... Introduction: Soil erosion in agricultural systems is a very important problem to manage. ... Soil erosion is the detachment and movement of soil particles by the erosive forces of wind or water. Soil detached and transported away from one location is often deposited at some other place.
Soil erosion is a global problem. Each year, erosion costs billions of dollars in loss of land productivity, damage from soil sediment deposition and subsequent restoration costs, and harm to plant, animal, and human health due to air and water pollution.
