Summary
Klimaberegninger for en økologisk planteavlsbedrift på 500 ha er gennemført med værktøjet ESGreen Tool. Effekten af at dyrke kløvergræs til biogasproduktion og bruge afgasset gødning med høj udnyttelsesgrad er vurderet. Tiltagene har en positiv klimaeffekt. Men værktøjet viser en negativ kulstofbalance, når husdyrgødning erstattes med afgasset gødning. Ved højere priser på husdyrgødning og reduceret pris på afgasset gødning bliver tiltagene økonomisk rentable.
Summary translation
Climate calculations for an organic arable farm of 500 ha have been carried out with the tool ESGreen Tool. The effect of growing clover grass for biogas pro-duction and using digestate fertilizer with a high Nitrogen efficiency has been assessed. The measures have a positive climate effect. But the tool shows a negative carbon balance when livestock manure is combined with degassed manure. With higher prices for livestock manure and a reduced price for biogas digestate, the measures will be economically profitable.
