Soil term paper

More so than other areas of specific sciences, Earth science is a general term that is used as an umbrella reference to all of its sub contexts.

From 5 to 2 mm Fine gravel From 2 mm to 0. Department of Agriculture has classified the soil into six textural classes: Besides shape, size and texture, the soils can be classified in terms of their ability to influence growth of the plant.

The different types of soils are: This fraction of soil contains coarse, textured, loose and friable particles which can be seen by naked eye.

Due to larger particle size, empty spaces remain in between sand particles and through these empty spaces, air and water can easily pass through the soil.

Sand is not suitable for the growth of the plant. It consists of medium textured soil particles of size intermediate in between sand and clay.

In dry condition it is flour like but in wet condition, it is like plastic. Hence it is fertile. It is fine textured soil of particle size ranging in colloidal dimension A.

It actively participates in physio- chemical reactions of the soil. The major types of soil are: It is an acidic pH 4. Its fertility is comparatively lesser. It is a blackish soil seen in the grassland areas. The soil is highly fertile and productive. It is nutrient poor soil seen in heavy rainfall areas near equator.

It is a grayish or greenish soil found in the desert areas of the world. It is highly alkaline and less fertile. A vertical section of the matured soil shows several layers, with distinct characteristic physical and chemical properties, which are known as horizons or soil horizons.

These layers or horizons from top to bottom together constitute soil profile. Each horizon has a specific thickness, structure, colour, texture, porocity, etc. The soil profile can be broadly divided into five horizons.

From the surface downwards, these may be named as O-horizon, A-horizon, B-horizon, C-horizon and R-horizon. The A and B zones together form the true soil or solum.

It is the surface layer of the soil and also known as top soil. This layer contains fertile soil mixed with organic materials in decomposed and semi-decomposed state, produced due to disintegration of different parts of plants.

The O-horizon can be further sub-divided to O1and O2 zones.

This layer is just below O1horizon.About the Journal Soil Research (formerly known as Australian Journal of Soil Research) is an international journal that aims to rapidly publish high-quality, novel research about fundamental and applied aspects of soil science.

Read this Essay on Soil: Classification, Profile, Composition and Soil Organism! The term ‘Soil’ has been derived from Latin word ‘Solum’ which means earthy material necessary for the growth of plants.

Soil may be defined as a mixture of organic as well as weathered rocK . Soil science deals with soil as a natural resource on the surface of the earth including soil formation, classification and mapping; physical, chemical, biological, and .

Soil pH or soil reaction is an implication of the acidity or alkalinity of soil and is measured in pH units. Soil pH is characterized as the negative logarithm of the hydrogen particle fixation. As the measure of hydrogen particles in the soil builds the soil pH diminishes along these lines getting to be more acidic.
