| Der har i den danske landbrugspresse i sommeren 2008 været en debat om fordele og ulemper ved anvendelse af egen udsæd i forhold til anvendelse af certificeret udsæd. Landscenteret har eksempelvis beregnet, at konventionelle landmænd kan spare 265-350 kr/ha ved at bruge certificeret udsæd på 10% af markerne, og bruge egen såsæd på resten. Omvendt fremhæver såsædsbranchen for det første, at den danske model, hvor langt hovedparten af landmændene køber certificeret såsæd er med til at finansiere dansk planteforædling, og dermed til at vi har de bedste sorter, og for det andet et certificeret såsæd er af en bedre kvalitet bl.a. på grund af bejdsning. I økologisk landbrug er forholdene anderledes end i det konventionelle landbrug. |

| Methods to investigate whether organic farming might help toreduce energy consumption and greenhouse gas emissions areneeded. The aim of this study is for the first to present anupscaling procedure, where an existing farm level energyconsumption model, in combination with the IntergovernmentalPanel on Climate Change’s guidelines, is used to calculateagricultural energy consumption and greenhouse gas emissionson the national level. Secondly, this procedure is used to simulatescenarios for conversion to organic farming in Denmark.Three scenarios for conversion to organic farming with thepresent crop yield and an expected improved future crop yieldare compared to the 1996-situation in Denmark, whereconventional farming dominates. In all scenarios, fossil... |

| Mælkens indhold af CLA er interessant ud fra en human ernæringssynsvinklen, idet flere undersøgelser har vist en positiv sammenhæng mellem indtag af CLA og risikoen for cancer. Der blev fundet en betydelig variation mellem bedrifter i mælkens indhold af CLA, og ikke noget entydigt billede af niveauet i konventionel og økologisk mælk. Resultater viser desuden at foderrationens sammensætning påvirker niveauet, men også at der synes at være en forskel mellem de enkelte køer. |

| Patterns in spring-active carabid assemblages were described in relation to four organic soil management regimes (no soil nutrient addition, undersowing, animal manure, undersowing + manure) in two areas of Denmark. On the island of Zealand, the Flakkebjerg study area had 22 species, 3-10 species/trap, and the species rank of these was the same for all treatments. The dominant species were Pterostichus melanarius, Agonum dorsale, Harpalus rufipes and Calathus fuscipes. At Foulum, Jutland, there were 46 species, 12-15 species/ trap, dominated by P. versicolor, P. melanarius, A. dorsale and Nebria brevicollis. Their rank, however, was not the same for all treatments. There were remarkable differences in the carabid assemblages of the two sites, and manure... |

| In both Finland and Sweden a family member collected the receipts or filled in purchase diaries for all food entering the household for human consumption during 14 days period. Information on the amount, price, origin and environmental brand of all food products was recorded. After the recording period, the families were interviewed about their food choices, food consumption and food purchasing habits. |

| Via public legislation minimum standards for the utilization of manure have been introduced as an obligatory part of fertilization planning. And many Danish livestock farmers have improved the utilization of manure during the last five to ten years. There is, however, still not consensus concerning the question of whether the results are sufficient to reduce the loss of nitrogen to ground water and the Danish marine environment to acceptable levels. In an analysis of 30 dairy farms Halberg et al. (1995) showed a variation in N surplus between 88 and 387 kg/ha depending on stocking rate and management. At ca. 1.4 livestock units1) per ha there was a difference between 250 and 116kg N/ha farm level surplus. It was concluded that differences between farms... |

| Der er ikke noget nyt i at økologer har deres udfordringer med ukrudt. Visse har bedre kontrol med ukrudt end andre – dog kan der være år, hvor selv de flittigste landmænd får et ukrudtsproblem. Meldinger rundt omkring tyder på, at 2010 var sådan et år. Som det fremgår af ”Vejret i vækstsæsonen” (side 2) har vejret i den overståede dyrkningssæson været usædvanligt. Dette har givet ukrudt herunder rodukrudt gode vækstvilkår i forhold til afgrøden. |
