Any soil has its own characteristic properties-physical, chemical, and biological. Each soil has its own structure and ability to tie together physical and chemical elements; different soils and their genetic properties. Often, students of ecological faculties have to look for the answer to the exam question: “What are the main properties of the soil”. In this case, it is possible to list several characteristics of the soil.
The Main feature of any soil is fertile. But it also depends on its other characteristics. Absorption capacity – one of the basic properties of the soil, without which the power plant would be impossible. The term “capacity” refers to the ability of the soil to absorb various substances from the solution that passes through it. K. K. Gedroits distinguished several types of this ability:
The Absorption capacity is one of the main properties of the soil, which affects how the soil is nutritious. Because plants suck only solutions of substances. In order of substances could be assimilated by the plant, the required low concentration. Of course, in some cases, the solution may be too weak, and then nutrients are not enough. But the plant will die and in that case, if the salt concentration is too high.
Increases the absorption capacity with increase in soil clay humus. Those soils that are rich in humus, it is always possible to fertilize safely. The surplus will be well absorbed and will not harm the plants.
This category includes the structure, air, thermal, physical and mechanical properties. Physical properties – density and porosity. Density of soils depends on their mineral composition, content of certain chemical substances. Porosity is called the total volume of all pores between the solid particles of the soil. Between the indices of density and porosity of soil is an inverse relationship-the higher the density, the less porosity.
Basic characteristics and properties of soil have long been studied by agronomists and this knowledge is successfully used to increase yield. One of the essential properties of the soil is warm. The ground receives from the sun, from the underlying layers, from the respiration of animals. While not all soils get hot equally fast. Light and wet soil warms up slower than dark soil. Faster absorb the sun's heat and sandy soil, in contrast to clay.

The origin of the Slavs. The influence of different cultures
Slavs (under this name), according to some researchers, appeared in the story only in 6 century ad. However, the language of nationality bears the archaic features of the Indo-European community. This, in turn, suggests that the origin of the Slavs h...
This figure also belongs to the main properties of the soil. In different natural zones, the humus content may be different. The large reserves it is characteristic of the Chernozem type soils. The humus content refers to the genetic characteristics, because the increase or decrease in the content of humus in the soil – this is an extremely long process. It is not the result of temporal phenomena; on the contrary, the high content of humus is always a result of complex soil-forming process.
The Presence and amount of certain chemical elements is also one of the main properties of the soil. Any soil is a four phase system – it includes solid, liquid, gas and alive components. Each of these components has its own chemical composition is one of the most important indicators, as a basic property of soil is fertility. The yield depends on what chemical elements are found in the soil.
