what are the different components of soil?
231902
The basic components of soil are minerals, organic matter, water and air. The typical soil consists of approximately 45% mineral, 5% organic matter, 20-30% water, and 20-30% air.

There are three basic types of soil: sand, silt and clay. But, most soils are composed of a combination of the different types. ... While this is good for drainage, it is not good for growing plants because sandy soil will not hold water or nutrients. Silt is another type of soil.

There are six main types of soil: chalky, clay, loamy, peaty, sandy and silty. To test your soil, you need to take a look at it and feel it. Add water and try rolling it between your hands.

Physical properties of soil include color, texture, structure, porosity, density, consistence, temperature, and air. Colors of soils vary widely and indicate such important properties as organic matter, water, and redox conditions.

Soil can be classified into 3 primary types based on its texture – sand, silt, and clay. However, the percentage of these can vary, resulting in more compound types of soil such as loamy sand, sandy clay, silty clay, etc. 2. State the characteristics of sandy soil.

Soil components photosynthesize, respire, and reproduce. In addition, they produce organic matter, consume organic matter, and decompose them. Some of them burrow in the soil, make spaces for their accommodation and movement, and mix surface and subsoil materials together.

['Alluvial soils: The most fertile soil is the alluvial soil. ... ', 'Black soils: Black soil is rich in calcium, potassium and magnesium but has poor nitrogen content. ... ', 'Red soils: Red soil are usually found in warm, temperate climate zones like India. ... ', 'Laterite soils: Laterite soil is formed due to intense leaching by rain water.']

Soil is a major source of nutrients needed by plants for growth. The three main nutrients are nitrogen (N), phosphorus (P) and potassium (K). Together they make up the trio known as NPK. Other important nutrients are calcium, magnesium and sulfur.
404733
A soil's physical and chemical properties affect plant growth and soil management. Some important physical and chemical properties of soil are mineral content, texture, cation exchange capacity, bulk density, structure, porosity, organic matter content, carbon-to-ni- trogen ratio, color, depth, fertility, and pH.

An ecosystem can be categorized into its abiotic constituents, including minerals, climate, soil, water, sunlight, and all other nonliving elements, and its biotic constituents, consisting of all its living members.

Soil texture is not a factor which is responsible for the soil formation. Parent material (minerals and nutrients), Time, Climate, Relief and Organisms are the factors which are responsible for the soil formation.
1217810
All soils contain mineral particles, organic matter, water and air. The combinations of these determine the soil's properties – its texture, structure, porosity, chemistry and colour.
947721
There are three types of soil particles: sand, silt and clay. Most soils are made up of a combination of sand, silt and clay particles. The ratio of these particles in any given soil sample identifies it as one of the three main types of soil: sandy, loam or clay.

Soil is an example of a heterogeneous mixture. It combines many different components which are not uniform, such as stone, clay, decaying plant material and even living things.
799665
The layers of soil can easily be observed by their color and size of particles. The main layers of the soil are topsoil, subsoil and the parent rock. Each layer has its own characteristics. These features of the layer of soil play a very important role in determining the use of the soil.

Humus, the organic material in soil, is composed of microorganisms (dead and alive) and decaying plants. The inorganic material of soil is composed of rock, which is broken down into small particles of sand (0.1 to 2 mm), silt (0.002 to 0.1 mm), and clay (less than 0.002 mm).
