Soil organic material, its components and reasons, why it is essential to differentiate them.
 KRÁTKÁ, Petra
We are learning about a soil organic material as a unit from diverse media or lay and specialist literature. This informations are not differing the parts and characteristic of the soil complex. There are also terminological discrepancies which lead to incorrect deduction about soil fertility, decrease of topsoil content and poor management. This is a reason, why I do a literary summary in my thesis about a soil organic material and an individial soil components. It is a essential to distinguish the soil components for their different quality and the different origin after transformation precess. My task was a term clarification in soil organic material segmentation. We can divide it in two major groups: primary soil organic material and stable topsoil. The primary soil organic material is decomposed in exothermic mineralization process and is a origin of a nutriants and an energy for the soil edafhon and plants. The topsoil is a stable organic material and its matters significantly affect fertility, nutrient content, structure, aerial, aquatic and thermic regime of the soil. Morover the topsoil matters has a highmolecular HK ability to the heavy metals absorbtion.
