🌱 World Soil Day

The 5th of December is World Soil Day! It was proclaimed in 2002 by the International Soil Science Union (IUSS). The aim is to draw attention to the importance of soil as a natural resource and to promote soil protection.

For more than 10 years, the IASP has been running a field experiment on the influence of different organic fertilisers at the field station in Berge (Havelland). The focus is on the effect of different fermentation residues from biogas plants on humus content and soil fertility. Together with our partners, the Thaer Institute for Agricultural and Horticultural Sciences at Humboldt University and the Helmholtz Centre for Environmental Research, the Department of Soil Science at the Technical University of Munich and the University of Wageningen, we are conducting research on carbon and nutrient dynamics in agricultural soils in various projects.

The work on the field trial was supported by projects within the framework of the "Renewable Resources" funding programme of the Federal Ministry of Food and Agriculture (BMEL) by the Agency of Renewable Resources (Fachagentur Nachwachsende Rohstoffe e. V.) and by the Federal Ministry of Education and Research  and by the EU project "Circular Agronomics" funding number 773649.
