Punktsåning og gasbrænding mod ukrudt i økologiske rækkeafgrøde Organic Eprints
Stubsgaard, Anke.
Hvis frøene til rækkeafgrøder som løg og gulerødder sås i punkter, uden at der graves en rille i rækken, vil det nedsætte fremspiringen af ukrudt markant. Det samme vil gasbrænding, der heller ikke roder op i jorden. Til gengæld kan der ikke vises effekt af punktsåning af sukkerroer.

Organic agriculture regulations, in particular European regulation EC 889/2008, prescribe the use of organically produced seed. For many cultivated plants, however, organic seed is often not available. This is mainly because investment in organic plant breeding and seed production has been low in the past. To bridge the gap between organic seed supply and demand, national and European regulations define certain circumstances under which organic producers are permitted to use non-organically produced seed. While the organic sector currently depends on these concessions, they also threaten to impede a further increase in the demand for organic seed, thereby potentially restraining present and future investment in organic seed production and plant breeding....
