For example‚ in Queensland a deep‚ fertile clay soil is suitable for intensive agriculture but a shallow‚ sandy soil is better suited to grazing and growing native trees. The suitability of a soil for a particular purpose can often be

Soil‚ which is one of the most important natural resources‚ is often less heeded. The importance of soil conservation is relatively less talked about as compared to the conservation of water and other natural resources. The almost-omnipresent soil is mostly taken for granted. Its omnipresence is ironically the reason behind us‚ human beings‚ taking it for a ride. We rarely even think of it as a natural resource that needs to be conserved‚ a part of the natural wealth that needs to be preserved.

Soil is the layer of broken rock particles and decaying organic matter on the surface of earth‚ which is essential for the growth of plants. It comprises of all the necessary nutrients that aid the growth and development of plants and trees. There are different types of soils‚ each one of them varying in its nature and texture. While some soils are deep rooted‚ the others are present on the margin. They also differentiate in their color‚ as some may be red while others are black. There are various

What Is Soil Pollution? Soil pollution comprises the toxic waste of soils with resources‚ mostly chemicals that are out of place or are present at concentrations advanced than normal which may have unpleasant effects on humans or other organisms. However‚ soil pollution is also caused by resources other than the undeviating addition of man-made chemicals such as undeveloped runoff waters‚ industrial waste materials‚ acidic precipitates‚ and radioactive clash. Both organic and inorganic contaminants

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

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
