In this
context, Rodhe et al. (2006), Kapuinen et al. (2007) and Bermejo and
Ellmer (2010) underlined the importance of the timing of digestate
application and its fractionation, when comparing crop yield from
digestate treated soil to that obtained with conventional mineral
fertiliser. It must be timed to avoid nitrogen losses (lost fertiliser
value), considering that nutrients bound to organic forms in the
digestate are released and hence available to plants after OM mineralisation.
Thus, digestate addition to soil must be adapted to the
plant requirements and climate conditions in order to reach the
maximum nutrient efficiency.
