Carbon Action

Effects of organic soil amendments on soil and root microbes

The aim of the project is to study what kind of effects organic soil amendments (different wood fiber types produced using industry side streams, and biochar types) have on microbes living in agricultural soil and oat roots. The focus is on impacts on diversity of microbial communities, microbial activity and carbon compounds in soil. Especially, impacts on oat root microbes will be studied.

Different research methods to detect changes in soil and root microbial communities and soil carbon stocks will be tested and develop during the project. The aim is to use results in Yasso or other model-based simulations. Microbial communities are studied based on soil DNA and RNA. The results of this short-term study will be published also in Finnish, so that information will be more easily available for Finnish farmers.

Climate smart northern agriculture (HY, HiLIFE Helsinki Institute of Life Science), STN Multi-benefit solutions to climate-smart agriculture (MULTA), and the Academy of Finland project DARKFUNCTIONS (#308128) are also participating in the project.
