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

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

Environmental pollution is the biggest menace to the human race on this planet today. The environment consists of earth‚ water‚ air‚ plants and animals. If we pollute the environment‚ the existence of man and nature will be hampered. Although most of people know that but they still destroy their own life.

The Effect of different soil types on plant growth Introduction Australian Gardeners are continually looking for better and cheaper options to improve the growth in their gardens. In Chinchilla‚ it is common to see rich vibrant coloured loam‚ but this is not suited to all plants. Common gardeners will find that it is important to understand what soil type they are on and how the climate conditions that surround the area may affect the growth of the plants they wish to establish‚ which contributes
