Summary
I fleirårige, fastliggande forsøk på Planteforsk Apelsvoll og Kvithamar undersøker ein kva traktortyngde, pløyedjup og køyremåte ved pløying har å seie for jordstruktur og avlingar i økologisk korndyrking. Etter to år er det framleis ikkje store utslag for forsøksfaktorane. Avhengig av vekst og tildels traktortyngde er det sikre utslag for pløyedjup, men avlingsvariasjonen innan felt og delvis mellom år er stort sett større. Djup pløying gav gjennomgåande større kornavlingar enn grunn pløying, men for bygg etter grønngjødsling på Kvithamar, som verken var tilført husdyrgjødsel eller mineralgjødsel, vart avlingane størst med grunn pløying.
Summary translation
The impacts of tractor weight, ploughing depth and ploughing method on soil structure and organic cereal yields are studied in a four-year field experiment at the Norwegian Crop Research Institute's research stations at Apelsvoll (Eastern Norway) and Kvithamar (Central Norway). After the first two years, there are no significant effects of the experimental factors. Depending on crop and partly on tractor weight there are significant effects of ploughing depth, however yield variations between plot and and partly between years are larger. Deep ploughing generally caused higher cereals yields than shallow ploughing, however in barley grown after green manure at Kvithamar, which received neither manure nor mineral fertiliser, the yields were higher with shallow ploughing.
