Laura E. Skadell, Florian Schneider et al.: Long-term management effects on depth gradients of ¹³C, ¹⁵N and C/N ratio in agricultural soils

The final report for the joint project "Denitrification in Agricultural Soils: Integrated Control and Modeling at Various Scales" (DFG FOR 2337, www.dasim.de) was published in March 2025 in the form of a special volume in the journal Biology and Fertility of Soils .

Many potting soils contain peat. Its degradation releases large amounts of greenhouse gases. That is why the government intends to counteract this with the federal peat reduction strategy. Researchers from the Thünen Institute have now investigated options for phasing out peat in hobby horticulture.

Ammonia is an environmentally harmful gas. It mainly originates from agricultural fertilization. A new study shows which adaptations in synthetic fertilizers are most effective in reducing ammonia emissions.

Greenhouse gas emissions in Germany declined in 2023. However, new data show that emissions from the land use, land use change and forestry (LULUCF) sector are higher than previously assumed.
