T 91 Energy crops for groundwater protection
The leaching of nitrate from perennial energy crops is low and the use of pesticides is also low. This is the basis for using energy crops for groundwater protection. Examples of the use of energy crops in Denmark are presented.
Tuesday 10 January 1:00 pm - 2:00 pm.
