Project: Stability of soil organic matter

Pricncipal investigator: Karin Kauer

Duration: 01.01.2018-31.12.2021

Finance program: Personal research funding: Start-up grant

Annotation: Soil organic carbon stock plays an important role in the global biochemical C cycle and soil is important carbon reservoir. Also the soil acts as the source of atmospheric CO2. The accumulation and decomposition of organic matter depends on the several factors: climatic conditions, land use managements etc.. The stabilization (turnover) of soil organic matter after the organic matter entering the soil is still poorly understood. A better understanding of the mechanisms and regulation of organic matter stabilization on soils requires a deeper insight into the chemical composition of soil organic matter. Understanding the mechanisms controlling the stabilization and release of C in soil are important for the prediction of the effects of global climate change and for the development of management strategies to increase soils C sequestration.
