Table 1 Amount of mineral fertiliser and digestate spread on the fields for each of eight fertilisation scenarios (SC) (see further details in the section “Evaluation scenarios”). Note, only one-third of the annual fertiliser rate was applied in the establishment year 2009 due to low nutrient demand of the germinating seeds
