Abstract
Field trials were carried out between 2002 and 2005 to investigate the effects of biogas digestion in a mixed organic dairy farming system with arable land and grassland on nutrient cycling nitrogen N uptake and crop yields within a cropping system comprising a whole crop rotation Five treatments were carried out i solid farmyard manure ii undigested liquid slurry iii digested liquid slurry iv digestion of liquid slurry and field residues such as crop residues and cover crops and v similar to iv but with additional N inputs at the equivalent of 40 kg N ha−1 farmland through digestion of purchased substrates The term “manure” is used in the present study to mean all kind of aboveground organic residues left on the field “immobile manures” such as crop residues and green manures incorporated directly into the soil or added as stable wastes or effluents of biogas digestion “mobile manures” The total aboveground biomass growth and the overall aboveground N uptake of nonlegume maincrops were higher in the liquid slurry manure treatment than in the solid farmyard manure system +5 and +9 respectively The digestion of the liquid slurry increased N uptake and crop yields only after soil incorporation of the slurry shortly after field spreading The additional collection and digestion of field residues such as cover crops and crop residues combined with a reallocation of the effluents strongly increased the amounts of “mobile” manure allowing a more focussed allocation of the available N This led to an increase in the aboveground N uptake +12 and biomass yield +4 of the five nonlegume crops due to a better adapted allocation of nutrients in space and time Results obtained with spring wheat showed that removal of cover crops in autumn and their digestion combined with subsequent use as manure in spring resulted in a better synchronisation of the crop N demand and the soil N availability in comparison with a strategy where the biomass was left on the field as green immobile manure The inclusion of external substrates led to a further increase of 8 in N uptake but not to a significant increase in aboveground dry matter yields
