What is the soil classification?

The

soil classification process is trying to assign a degree or name to different types of land on Earth because they relate to specific applications. There are several degrees of land, depending on whether the required information for engineering, agriculture or geology is. In some fields, several soil measurement systems have developed. In addition, several countries maintain their own charts of land comparison. The actual process of soil classification may vary from industry to industry. For some applications, the only elements are considered to classify the only elements. In fields such as engineering, in addition to appearance, soil is assessed to hold the structure. Agricultural analysis often consists in measuring the size of soil or the levels of pH. This system uses two measurements to define the type of land in a given area. The first measurement is a texture that can be gravel, sand, mud, clay or organic. The second measurement is the grain size that may differ from poorly graded to well -graded and from low plasticity to vYSokou plasticity. These two measurements are represented by a two -letter system in which the combination describes the soil.

The Ministry of Agriculture of the United States (USDA) has created a much more complicated soil classification system. According to USDA's instructions, there are more than 20,000 land types in the United States. Each of these land is given a name that usually reflects the area in which it was found. Different types of soil are classified in relation to other types according to dozens of real estate, including the origin of its creation.

There are many derivative and independent soil of the stuffing of lysification graphs. The US Asso Association (AASHO) has its own specific graph, which is used to determine the feasibility of road construction or motorways at the top of various types of land. This chart shares some aspects with other systems, but is unique to Aashho and focuses primarily on how the soil will come in handy when used JAKO base for the road.

Globally, Food and Agriculture (FAO) UN has set up a worldwide soil classification system. This system is trying to provide a wide definition of soils of the region. It has three primary measurements. The first is the property of the soil or phase that can be considered as a soil class such as Cambisols. The second is a texture such as a course or okay. The third is the inclination of the land on which the soil is found.
