Soil ecology

Soil ecology is both a branch of soil science, the other a branch of ecology. It examines the inter-relationships within the organisms in the soil and to the abiotic parts of the floor.

Substantive

In contrast to other fields of soil science, the focus is on the organisms, the so-called Edaphon. Soil ecology is a multidisciplinary, interdisciplinary research direction.

In addition to the basic research for modeling application-related questions are addressed that arise from changing environmental conditions for the soil ecosystem and indirectly have implications for the sustainable management of soil and environmental protection.

Examples are the themes soil acidification (acid rain) and nutrient leaching; the study of biogeochemical cycles - the entry of toxins or copper by spraying heavy metals, sulfur, nitrogen in the soil due to air pollution, as well as the consequences for soil organisms; Effects of this substance inputs on the rooting and nutrient availability in the rhizosphere and the change of the soil itself

Interesting for the application of research results is the development of characteristic and indicator organisms for the monitoring and control of biochemical processes, such as the formation of humus and the metabolism atmosphere - plant - soil.

Examples of current issues

• Soil acidification and consequences for nutrient leaching, root growth and nutrient uptake;
• Effects of heavy metals and organic pollutants on soil organisms; see under ground;
• Effects of higher atmospheric CO2 concentrations on the nutrient cycle;
• Mineralization of sulfur compounds in forest soils;
• Microbial stability of dissolved organic nitrogen compounds.
• Effect of thermal methods for soil sterilization (for example vapors ( soil disinfection ) ) on the Edaphon
