Effects of digestate on the environment and on plant production - results of a research project [PDF]

, 2008
Composts and digestates can influence soil fertility and plant health. These influences can be positive or negative, depending of the quality of the composts. A currently important question is to know, if digestates differ from composts in these aspects.
