Marcus Schiedung, Axel Don et al.: Soil carbon losses due to priming moderated by adaptation and legacy effects

Labelled roots growing in the soil during pre-incubation

Ronny Seidel, Ullrich Dettmann, Bärbel Tiemeyer: Reviewing and analyzing shrinkage of peat and other organic soils in relation to selected soil properties

3D models of a soil sample at saturated and ovendry moisture state. Usually, shrinkage is non-linear and can reach values of more than 90%.

Martin ten Huf, ..., Caroline Buchen-Tschiskale et al.: Evaluation of calibrated passive sampling for quantifying ammonia emissions in multi-plot field trials with slurry application

Measuring NH3 emissions using acid traps

In the last few days two papers have been published that fit together very nicely and have given us deeper insights into the dynamics of soil carbon after organic matter inputs differing in qualtiy and quantity. Christopher Poeplau first author of one paper and involved in the other paper.

Typical soil profiles of the different peat soils

Our deputy head of institute Axel Don has been awarded the title "Extraordinary Professorship" by the Technical University of Braunschweig.

Christopher Poeplau, Axel Don: A simple soil organic carbon level metric beyond the organic carbon-to-clay ratio

Laura E. Skadell, Florian Schneider et al.: Twenty percent of agricultural management effects on organic carbon stocks occur in subsoils – Results of ten long-term experiments

Subsoil is defined as the soil below the tilled soil layers, starting at an average depth of 30cm. This study shows that subsoil is also affected by agricultural management and must therefore be taken into account when determining changes in soil organic carbon stocks.
