In September 2020, the 4th edition of the symposium "Crop Utilisation of Digestate from Biogas Plants" took place - organised in the proven manner by the Agency "Nachwachsende Rohstoffe" e.V. (FNR) with scientific support from IASP but for the first time organised as a virtual conference with online participation. The complete conference proceedings have now been published. In it, scientists and practitioners present their approaches and proposed solutions to meet the increasing demands on digestate handling in the future, to keep the nutrients in the cycle and not to shift them into the soil or into the air in the long term. The conference proceedings have been published as volume 60 in the series "Gülzower Fachgespräche" and are available in the FNR media library.
