| Soil properties at the beginning of the MEE (Multi Environment Experiments) were statistically analyzed in order to verify the field homogeneity. The initial soil properties represent the starting point to interpret the effect of CC and LM on soil fertility during crop cycle.Soil properties of the fields were quite homogeneous at the beginning of crop cycles (first and second). The soil properties of the experimental fields in the selected areas showed a wide variety of pedons to be used for the comparison of CC and LM effect in different climate zones. Soils from the Northern European sites are more acid and richer of nutrients and organic matter with respect to the soils in Southern sites. |

| Jordbearbetning är en effektiv kontrollmetod mot perenna ogräs, såsom kvickrot (Elymus repens L.), delvis på grund av att bearbetningen sönderdelar ogräsens underjordiska lagringsorgan (rhizom). Jordbearbetning ökar dock risken för näringsläckage, och det är svårt att kombinera jordbearbetning med en växande gröda. I denna studie använde vi oss av en prototyp med vertikala diskar för att fragmentera kvickrotens rhizomer med minimal störning av jord och gröda. Målet var att utveckla en metod för kvickrotskontroll i gräs-klövergrödor med en kombination av rhizomfragmentering och putsning. Experimenten utfördes 2014 och 2015 i Uppsala, med rhizomfragmentering utförd innan sådd (TRF), i den växande grödan (SRF) eller både och (TRF + SRF).... |

| Preliminary results show that there is room for improvement within existing control methods of couch grass (Elymus repens (L.) Gould). It may be possible to reduce the number of stubble cultivations during autumn by timing the treatment, and to reduce the cultivation depth by using a goose foot cultivator (5 cm) instead of a disc cultivator (10 cm), without sacrificing couch grass control efficiency. The first year of the experiment, the use of a goose foot cultivator resulted in less nitrogen leaching than cultivation by disc. A reduced number of stubble cultivations potentially reduces nutrient loss, fuel consumption and the workload of the farmer. Our experiments with cover crops to control couch grass in cereals has yet to prove significant effects... |
