Biomass of weeds, crops and arthropods in conventional and organic cereal fields

Summary in the original language of the document

Crop, weeds and arthropods were sampled in conventionally and organically cultivated spring- and winter-sown cereal fields. Weed biomass was much higher in organically cultivated fields, while arthropod biomass hardly showed any differences. Results from very weedy areas of organically grown fields indicate that a more extensive management allowing even more weeds may be favourable to insects and the animals feeding on them.
