Soil Chemistry

The chemistry of soils.


Soil chemistry is the interdisciplinary branch between soil sciences and chemistry and studies the chemical characteristics of soil.

Soil is made up of the solid particles and water, air, microorganisms and plant roots contained upper layer of the earth's crust, which is caused by erosion of the rocky subsoil. The soil chemistry can therefore be regarded as a part of the field of geochemistry.

The soil chemistry concerned with the chemical composition and chemical changes of these layers. Especially of interest are the chemical properties of the soil, such as the composition of the different soil types and layers, the exchange operations (delivery and absorption of nutrients, ion exchange, base saturation), the pH value and buffering.

In addition, natural and artificial chemical factors are considered and investigated, but which lead to changes in the soil and soil improvement.

Closely linked to the soil chemistry are other branches of chemistry, who are close to the soil ecosystem, such as water chemistry, agricultural chemistry, biogeochemistry, atmospheric chemistry or environmental chemistry.
