Discusses Three Major Causes Of Soil Erosion And How They Can Be Corrected

Introduction Soil erosion is one form of soil degradation along with soil compaction, low organic matter, loss of soil structure, poor internal drainage, salinisation, and soil acidity problems. These other forms of soil degradation, serious in themselves, usually contribute to accelerated soil erosion. Soil erosion is a naturally occurring process on all land. The agents of soil erosion are water and wind, each contributing a significant amount of soil loss each year in Ontario. Soil erosion may be...

How To Prevent Soil Erosion

How to Prevent Soil Erosion TERRACING  Terrace farming is a farming method that makes use of a hill to create a multiplatform farm. There are severals steps known as andenes which are built into the side of a hill. The idea behind it is that any rain that falls and builds up on the andenes will overflow into another andene below, making the most out of the nutrients it provides.   CROP ROTATION The successive planting of different crops on the same land to improve soil fertility and help...

Soil Erosion

Soil 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. Soil is formed at a rate of only 1 cm every 100 to 400 years and it takes 3 000 to 12 000 years to build enough soil to form productive land. This means that soil is a nonrenewable resource and once destroyed it is gone forever. If we disregard this, a...

Soil Erosion

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).

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.

soil erosion

Soil erosion This is the loss of topsoil by wind and water. It is a natural process, happening all the time, but usually slowly because of the protective covering of vegetation. New soil formation from weathering of surface rocks can generally keep pace and replace what is being lost. Rates of soil erosion are highest in dry climates where there is little surface vegetation to shelter the soil against wind, or on steep slopes in wet climates where the gradient increases the speed of surface water...

3 Major Practicies That Affect Soil Erosion & How It Can Be Corrected

Throughout the world soil is constantly being eroded. There are three major principles that can cause soil to erode, leading to soil degradation. Over-cultivation, overgrazing, and deforestation have huge impacts on the degradation of the soil. There are, however, actions that can be taken to preserve or correct the conservation of soil. To further understand the prevention of degradation, we must fully comprehend the major causes of soil erosion. One major cause of soil erosion is over-cultivation...

What is Soil? Soil is the surface of the earth’s crust where plants have their roots and where many small animals make their home. It is also a result of the breakdown of rocks. Formation of Soil Soil is formed when rocks break down into very small particles by various processes such as weathering. There are two types of weathering: Physical Weathering and Chemical Weathering. Physical Weathering arises from the heating and cooling, the wetting and drying, and the freezing and...

Causes of floods Flood is overflow of the huge amount of water onto the normally dry land. Flood occurs when the overflowing water submerges land and causes deluge. It is a cruel and violent expression of water. Catastrophic floods are the floods that are caused by some significant and unexpected events, for instance dam breakages. Heavy rainfalls are one of the major causes of floods. The level of water in rivers or lakes rises due to heavy rainfalls. When the level of water rises above the...

Soil Pollution and Soil Waste Management

Soil is an important natural resource that covers much of the earth's land surface. All life on earth depends on the soil as a direct or indirect source of food. Plants are rooted in the soil and obtain nutrients (nourishing substances) from it. Animals get nutrients from plants or from animals that eat plants. Certain microbes in the soil cause dead organisms to decay, which helps return nutrients to the soil. In addition, many kinds of animals find shelter in the soil. Soil contains mineral...

Soil Erosion

There are three major causes of soil erosion: overgrazing, over cultivation, and deforestation. Together, these three problems cause more problems by creating unsustainable societies. Luckily, overgrazing, over cultivation, and deforestation can be fixed and the unsustainable society becomes a sustainable one. Overgrazing is when there are more animals in comparison to land, meaning that there isn’t as much food for the animals to eat, like grass and plants. When this happens, the soil becomes...

Physical weathering is breaking rock by force. ex: hitting, scratching, cracking Frost action (AKA ice wedging)- Water seeps into small cracks in rocks. When the water freezes it expands creating great pressure. The crack widens and allows water to seep deeper into the rock. (Robert Frost’s Mending Wall makes a reference to a frost...
