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 bare and exposed

Soil and its types: What is the Soil? ‘Soil’ is the thin layer on the surface of the Earth on which the living beings survive. Soil is the layer which is composed with many substances; in this layer various plants have their roots. Soil is made of many substances like weathered rock particles‚ and decayed plant and animal matter. Soil is made of diverse materials like broken down rock particles and organic material. There are different types of soil and various ways to classify it. Classification:

Soil properties are the result of the five soil forming factors; parent rock‚ climate‚ topography‚ organisms and time (Bockheim‚ et.al.‚ 2014). This is why there is a wide variety of soil types throughout Australia‚ but are there systematic differences between different regions? This essay will determine whether Australian tropical soils are different from soils of the rest of the country. The tropics are the regions between the latitude lines of the Tropic of Cancer and the Tropic of Capricorn (Seidel

Soil is one of the main elements in the environment‚ it covers most of the dry part of the Earth’s crust‚ and the content of the materials‚ including salts‚ it is very important for the green vegetation cover on earth. On the other hand soil is one of the main components of construction‚ study of soil in the workplace is one of the first steps in the beginning of the project‚ and the lack of knowledge of soil characteristics and types and how to deal with it may lead to the failure of projects in

A soil horizon is a layer parallel to the soil surface‚ whose physical characteristics differ from the layers above and beneath. Each soil type has at least one‚ usually three or four horizons. Horizons are defined in most cases by obvious physical features‚ chiefly colour and texture. These may be described both in absolute terms (particle size distribution for texture‚ for instance) and in terms relative to the surrounding material‚ i.e. ‘coarser’ or ‘sandier’ than the horizons above and below

Q1. You are asked to create soil that would be considered very fertile. What would you include in your "recipe?" I would try to create a soil order all of my own‚ combining Inceptisols and Mollisols unique characteristics. My terrain for my soil to be placed would be on a mostly flat to gently sloping surface to provide good drainage‚ minimum erosion‚ and sufficient time for nutrients to drain into the soil. My “O” soil horizon will be mostly compost made from fallen leaves and other organic

Soil formation‚ or pedogenesis‚ is the combined effect of physical‚ chemical‚ biological and anthropogenic processes on soil parent material. Soil is said to be formed when organic matter has accumulated and colloids washed downward‚ leaving deposits of clay‚ humus‚ iron oxide‚ carbonate‚ and gypsum. As a result‚ horizons form in the soil profile. These constituents are moved (translocated) from one level to another by water and animal activity. The alteration and movement of materials within a soil
