What is soil erosion? Soil erosion is a natural process‚ occurring over geological time‚ and indeed it is a process that is essential for soil formation in the first place. With respect to soil degradation‚ most concerns about erosion are related to accelerated erosion‚ where the natural rate has been significantly increased mostly by human activity. Soil erosion by water is a widespread problem throughout Europe. Soil is naturally removed by the action of water or wind: such ’background’

defined as soil. Soils come in an almost infinite variety of vertical structures and textures. Most soils are hundreds of years old and change very slowly. The work ability of the soil is the ease in which a soil can be cultivated and is determined by the soil texture. There are distinct layers of soil that are not always visible to eye but are made up of different horizons. O horizon/Humus is the decomposing plant matter. A Horizon/Topsoil is the mixed humus and leached mineral soil. E Horizon/

October 20‚ 2014 1st Period Mr.MayesSoil Texture Lab Report Introduction Soil texture is one of the most important physical properties of soils. Soil texture is related to a number of important soil characteristics such as water holding capacity‚ soil drainage‚ and soil fertility. In order to make this lab work to our own convenience we will use soil from our nearby area. This project was conducted to specify what type of soil there is in the area and what it can be used for. Agriculturist may be able

INTRODUCTION Soil is the precious gift of nature to the mankind. All the plant family‚ animal kingdom and human society at large depend upon soil for their sustenance directly or indirectly. Ironically‚ soil is the most neglected commodity on the earth. Shifting cultivation on the hill slopes‚ non-adoption of soil conservation techniques‚ and over exploitation of land for crop production due to population stress‚ leads to enormous soil erosion. It will take hundreds of years to form an inch of soil‚ but

Soil Erosion Erosion is a natural process by which rock and soil are broken loose from the earth’s surface at one location and moved to another. Soil erosion forms and changes land by wearing down mountains filling valleys‚ and making rivers appear and disappear. Erosion is usually a slow and gradual process that occurs over the course of thousands or millions of years. However the rate of erosion can be speeded up by such human activities as mining. How erosion occurs? Ero0sion begins with

Soil erosion is a major concern in the southeastern region of Nigeria due to high population densities and farming techniques‚ which has resulted in the presence of numerous gullies. While gullies are found all around the world‚ the existence of gullies in Nigeria is regarded as one of the worst environment disasters‚ having negative implications on the environment and the quality of life for humans and other species (Adetona & Ezezika‚ 2011; Ajaegwu & al‚ 2010). Large quantities of soil in Nigeria

Soil Pollution The process of contamination of the land surface of the earth is referred to as land pollution. It results from human activities that cause imbalance in nature. Dumping human and industrial waste harmful agricultural practices and exposing the land to harmful chemicals leads to the pollution of land. We speak of water and air pollution and rarely even think of the adverse effects of land pollution. Let me share with you some of the important facts about land pollution. Land

When I was researching for this essay explaining what soil and water conservation means to me‚ I found two quotes that really stuck out to me. One written by Franklin D. Roosevelt stated‚ “A nation that destroys its soils destroys itself. Forests are the lungs of our land‚ purifying the air and giving fresh strength to our people.”‚ and another that was written by an unknown author read‚ “Water is life’s mater and matrix‚ mother and medium. There is no life without water.” I am not sure about you

Soil Salinity Salinity in both the rivers and on the land is one of the main and most costly results of overclearing and irrigation. Salinity is caused by changes in the delicate balance between surface water and groundwater systems. A small increase in the infiltration of water from the topsoil to the groundwater‚ due to rainfall or irrigation‚ can result in a dramatic rise in groundwater pressure and watertable levels. The trees of the open forests are now replaced by shallow-rooted crops and
