Session 3 “Effects of energy crop cultivation on soil functions”
(24 November 2014, 04:00 - 6:30 pm, room 1C)
Soils provide many important functions for plants, animals and humans. In the Session “Effects of energy crop cultivation on soil functions”, we will analyze the main impacts of energy crop cultivation on soil functions. In particular, we will discuss to what extent biogas digestate application is influencing the soil organic carbon, an essential component of soil fertility.
Key questions:
- Application of biogas waste into soil as fertilizer: impact on GHG emissions, soil processes (denitrification, nitrification), soil microbial growth kinetics
- How does the cultivation of energy crops affect soil properties, soil organic carbon sequestration?
