3 Introduction Soil science – science about soils, their formation (genesis), a structure, structure and properties, regularities of geographical distribution. Soil science is the study of soil as a natural resource on the surface of the Earth including soil formation, classification and mapping; physical, chemical, biological, and fertility properties of soils; and these properties in relation to the use and management of soils. Introduction Soil science – science about soils, their formation (genesis), a structure, structure and properties, regularities of geographical distribution. Soil science is the study of soil as a natural resource on the surface of the Earth including soil formation, classification and mapping; physical, chemical, biological, and fertility properties of soils; and these properties in relation to the use and management of soils.

4 Sometimes terms which refer to branches of soil science, such as pedology (formation, chemistry, morphology, and classification of soil) and edaphology (how soils interact with living things, especially plants), are used as if synonymous with soil science.

5 The diversity of names associated with this discipline is related to the various associations concerned. Indeed, engineers, agronomists, chemists, geologists, physical geographers, ecologists, biologists, microbiologists, silviculturists, sanitarians, archaeologists and the advancement of the soil sciences.

6 Main part Soil scientists have raised concerns about how to preserve soil and arable land in a world with a growing population, possible future water crisis, increasing per capita food consumption, and land degradation. Main part Soil scientists have raised concerns about how to preserve soil and arable land in a world with a growing population, possible future water crisis, increasing per capita food consumption, and land degradation.

7 Pedology is the study of soil in its natural setting.

8 Edaphology is the study of soil in relation to soil-dependent uses. Both branches apply a combination of soil physics, soil chemistry, and soil biology.soil biology

9 Factors of soil formation: Climate Vegetation Fauna Time Rocks human activity Groundwater Relief Soil survey, or soil mapping, is the process of determining the soil types or other properties of the soil cover over a landscape, and mapping them for others to understand and use. It relies heavily on distinguishing the individual influences of the five classic soil forming factors.

10 Conclusion Soil science is the science of soils. The founder of soil science V.V. Dokuchaev. He introduced the concept of five soil-forming factors. Soil change depends on many factors: climate, time, vegetation, wildlife, human factors, topography, groundwater and rocks. Soil science is associated with other sciences: physics, chemistry, geography, biology.
