| This paper compiles statistics for certified organic farmland and organic consumption in the eight Nordic-Baltic countries, and describes main drivers and obstacles, focusing on policy and strategies including organic research. Significant differences are found between the countries, also between countries with relatively comparable climatic and economic conditions. Explanations are discussed. Successful examples, especially Denmark and Sweden, show that organic agriculture is an option for refreshing agriculture in general, when there is a significant political will to support this farming practice. |

| Cirsium arvense and Elytrigia repens are perennial weeds prevalent in organic cropping systems in Scandinavia. This study analysed the population dynamics of both species in long-termed crop rotation experiments conducted at three sites (coarse sand, silt and sandy loam) in Denmark from 1997-2008. The purpose was to gain insights into the factors influencing perennial weeds population changes over time, especially those important for outbreaks of C. arvense and E. repens infestations. Data were obtained from three cycles of four-year crop rotations with various cash crops and annual grass-clover subjected to four treatment combinations: with and without animal manure and with and without catch crops. The perennials were controlled by different tillage and... |

| The effect of nitrogen (N) supply and weeds on grain yield of spring barley was investigated in an organic farming crop rotation experiment on three different soil types in Denmark from 1997 to 2001. Three experimental factors were included in the experiment in a factorial design: 1) crop rotation (lupin or pea/barley as previous crop to barley), 2) cover crop (with and without), and 3) manure (with and without). The crop rotations included grass-clover as a green manure crop. Animal manure was applied as slurry in rates corresponding to 40% of the N demand of the cereal crops. Application of 50 kg NH4-N ha-1 in manure (slurry) increased barley grain DM yield by 1.0 to 1.3 Mg DM ha-1, whereas the use of cover crops (primarily perennial ryegrass)... |

| Der er igangsat forsøg med økologiske sædskifter på fire forskellige steder i Danmark, afspejlende forskellige klima- og jordbundsforhold. De fire sædskifter har forskellig andel af kvælstoffikserende afgrøder hhv. korn til modenhed, med og uden fangafgrøder og med og uden husdyrgødning. Forsøgene har været gennemført i 1997 og 1998. I forsøgene er bl.a. registreret ukrudt. Det er for tidligt at sige noget om ukrudtets udvikling i de forskellige sædskifter. Der er mest ukrudt i vintersæden begge forsøgsår alle steder. I 1997 er der i de vårsåede afgrøder mest ukrudt i byg/ært. Der er signifikant mest ukrudt i de gødede led af vinterhveden i forhold til de ugødede i Flakkebjerg 1997 og Foulum 1998. Ukrudtsbekæmpelsen har kun haft signifikant effekt på... |

| I Danmark dyrkes en del vintersæd økologisk – især vinterhvede, men også rug og triticale. Et af problemerne i vintersæden kan være ukrudtsbekæmpelse. Mekanisk ukrudtsbekæmpelse i vintersæd frembyder både nogle problemer og nogle muligheder. Forskningsresultater viser, at med et lavt ukrudtstryk kan vintersæden sås til normal tid ved almindelig rækkeafstand og der kan udføres ukrudtsbekæmpelse ved ukrudtsharvning efterår og forår, men ved højt ukrudtstryk og især forekomst af arter med pælerod og strækningsvækst som lugtløs kamille (Tripleurospermum inodorum), korn-valmue (Papaver rhoeas) m.fl. vil det være mere hensigtsmæssigt at så sent, på stor rækkeafstand og med høj udsædsmængde, så der kan udføres radrensning kombineret med ukrudtsharvning. I det... |

| The aim of this review is to provide an overview of weed control methods available for organic farming systems based on research mainly from Europe and North America, but measures mentioned here are not necessarily allowed in organic farming. Biological control of weeds is not considered in this review. |

| The effect of nitrogen (N) supply through animal and green manures on grain yield of winter wheat and winter rye was investigated from 1997 to 2004 in an organic farming crop rotation experiment in Denmark on three different soil types varying from coarse sand to sandy loam. Two experimental factors were included in the experiment in a factorial design: 1) catch crop (with and without), and 2) manure (with and without). The four-course crop rotation was spring barley undersown with grass/clover - grass/clover - winter wheat or wheat rye - pulse crop. All cuttings of the grass-clover were left on the soil as mulch. Animal manure was ap-plied as slurry to the cereal crops in the rotation in rates corresponding to 40% of the N de-mand of the cereal crops.... |
