A recent study by the Thünen Institute of Climate-Smart Agriculture assessed data on soil carbon content and stocks in arable soils under organic and conventional farming in Germany. The surprising finding: the soil carbon in organically farmed fields hardly differs from that in conventionally…

Graphic shows: A third of Land-Use Change induced soil organic carbon change occurs in the subsoil. Soil group is the most important factor for determining the magnitude of soil organic carbon (SOC) change in response to land-use change.

There are sample rings in an excavated pit.

A functional measurement network for Germany's moorland areas is now in place. A total of 155 measuring points have been set up in open land and forests. Today, Thünen researchers are submitting their report on the development phase to the Federal Ministry of Agriculture, Food and Regional Identity.
