| Bees and other pollinating insects contribute significantly to the world’s production of edible crops. Bees and bumblebees are threatened by modern agricultural practices like monocropping, destruction of natural habitats and pesticide use. Organic farming practice avoids the pesticides, but should also actively support the living conditions for pollinating insects, e.g. by maintaining flowering strips and trees. A recent ban on imidacloprid as rapeseed coating in Norway may encourage research in alternative ways of protecting rapeseed against ground flees (Phyllotreta spp.). Such studies may be beneficial also for organic rape growers. |

| The Norwegian government has since 2006 had a goal of 15 % organic food production and consumption, initially by 2015 and later adjusted to 2020. The goal has primarily been justified by consumer demands, and to some extent by environmental benefits. Organic farming is said to be a “spear point” in the development of a more environmental friendly and sustainable agriculture in Norway, but the government’s policy lacks thorough political support and the goal is far from achieved. In 2012, certified land and land area under conversion to organic farming comprised 5.6 % of the agricultural area (Debio 2013). The turnover of organic products was more than 1.1 billion NOK in 2012; an increase of 11 % from 2011 (NAA 2012). In 2009, organic food represented 1.3... |

| Anaerobic digestion of animal slurries and plant residues is a valuable technology to produce bioenergy and fertilizers in organic farming systems, while at the same time reducing propagules of weeds and parasites in the input material. However, the digestion changes the quality of the slurry by reducing its content of organic matter and increasing mineral nitrogen (N) levels. This may have profound impact on soil fauna and microorganisms as well as the biogeochemical processes they drive. Organic farmers fear that application of digested materials may have negative implications for soil fertility by reducing the input of organic matter to the soil, compared to fertilizing with traditional animal slurries or green manures. Hence, it is important to gain... |
