| I forskningsprojektet RowCrop er forskere fra Aarhus Universitet sammen med virksomheden AGRONINTELLI i gang med at udvikle redskaber til et nyt dyrkningssystem med plantevækst på marken året rundt. Sådan et system har mange fordele, men stiller også nye krav til dyrkningsteknik og markredskaber, hvis det skal kunne bruges af økologer, som ikke har mulighed for at benytte sig af ukrudtssprøjtning. Plantedække året rundt kan først og fremmest forebygge udvaskning af næringsstoffer og erosion og sikre en bedre jordstruktur, men et sådant dyrkningssystem kræver, at man etablerer en efterafgrøde i forbindelse med rækkerensning i hovedafgrøden. Den metode er velkendt, men mekanisk rensning af efterafgrøden i hovedafgrødens stub er en udfordring |

| New camera technology capable of detecting crop rows now makes it possible to employ selective weed control in spring cereals. Cereals are normally grown at 125 mm inter-row spacing but even moderate extension of the spacing can make enough room for automatically steered inter-row hoeing; the technology is being employed on an increasing number of organic farms. However, intra-row weeds, i.e. those growing in the crop lines, are not controlled and increasing the inter-row spacing to ≥ 250 mm may cause a yield penalty. The aim of this study was to investigate the interaction between inter-row cultivation, inter-row spacing and nitrogen rate on weed and crop growth. Results encompass four years field experimentation with spring barley and spring wheat... |

| Flex-tine weed harrowing conducted as a full-width operation treating both crop and weeds is the principal method for direct weed control in organic spring cereals in Northern Europe. Results with this technology have varied considerably where especially crop injuries and control failures against tall-growing and tap-rooted weed species have been major drawbacks. New camera technology capable of detecting crop rows makes it possible to employ selective weed control in spring cereals. Normally cereals are grown at 12.5 cm row spacing in Northern Europe but even a moderate extension of the row spacing can make enough room for implementing automatically steered inter-row hoeing. Experiences from practice have shown that camera-based steering systems can guide... |
