| On five long-term organic dairy farms aiming at self-sufficiency with nutrients, soil concentrations of ammonium-acetate lactate extractable potassium (K-AL) and acid-soluble K was measured twice in topsoil (0-20 cm) and subsoil (20-40 cm) over periods of 6-14 years. Organic management had occurred for >9 years at the second sampling. On average there were most probably field level K-deficits. Even so, topsoil K-AL concentrations were medium high (65-155 mg K kg–1 soil), and did not decrease during the study period. However, for three farms, topsoil K-AL was approaching a minimum level determined by soil texture, where further decrease is slow. Subsoil K-AL concentrations were generally low (<65). The soils were mostly light-textured, and reserves of... |

| From 2002 to 06, the annual dropout rate of certified organic farmers averaged 7.3%. A project was started in 2007 to explore farmer’s reasons for opting out of certified organic production. Important factors seem to be public regulations including standards for organic farming, agronomy, economy, and farm exit. While many organic farmers with relatively small holdings have opted out, farmers with more land and larger herds tend to convert to organic agriculture. The trend towards larger-scale farms in organic than in conventional agriculture, encouraged by the design of the organic farming payments, challenges the organic principles of diversity and fairness. Means should be considered to ensure that small organic enterprises are also economically viable. |

| In Norway, public procurement of food to youth is not well developed in comparison to many other European and Scandinavian countries. School meals are only offered in very few primary schools, and the common school meal is a packed lunch (sandwiches) brought from home, consumed in the class room. Subscription schemes for milk were introduced around 1970, and for fruit around 1995. Organic milk and fruit is offered only in some regions. Since 2007, fruit is served without payment in all schools with a lower secondary level (class 8-10 or 1-10). This effort was introduced as a first step to develop a free school meal in all public schools, which is a goal of one of the political parties in the current government. As in many other European countries, free... |

| By restricted access to manure, nitrogen (N) supply in organic agriculture relies on biological N-fixation. This study compares grain yields after one full-season green manure (FSGM) to yields with repeated use of a green-manure catch crop. At two sites in south-eastern Norway, in a simple 4-year rotation (oats/wheat/oats/wheat), the repeated use of ryegrass, clover, or a mixture of ryegrass and clover as catch crops was compared with an FSGM established as a catch crop in year 1. The FSGM treatments had no subsequent catch crops. In year 5, the final residual effects were measured in barley. The yield levels were about equal for grains with no catch crop and a ryegrass catch crop. On average, the green-manure catch crops increased subsequent cereal... |

| On 24 June 1991, the Council of the European Union adopted Regulation (EEC) No 2092/91 on organic production of agricultural products and indications referring thereto on agricultural products and foodstuffs. As well as defining the required method of production of crops and livestock they also regulate labelling, processing, marketing, import and inspection. The research project iPOPY compares and analyses procedures for certification of food-serving outlets within its participating countries (Norway, Denmark, Finland and Italy) using Germany as a reference. While Denmark chooses government agencies to carry out the inspection and certification, Italy, Finland, Norway and Germany choose a state-supervised private system. With the exception of Italy all... |

| Laying hens are specialized for egg production, and high costs for slaughtering challenges the utilization of killed hens for food purpose. Alternative utilization, such as for production of meat and bone meal, may be hampered by lack of rendering plants. E.g. in Norway, hens are commonly killed by gassing on farm, and transported to a centralized incineration plant. The bodies contain high amounts of nutrients, which may be utilized as fertilizer. A study was conducted to measure the fertilization effect of residues after hydrolysis of grinded slaughtered hens, and to explore the decomposition of chopped killed complete hens. This paper presents the main results. |

| The diversity and density of springtails (Collembola) were studied in an organically managed grass-clover ley at Tingvoll experimental farm in NW Norway during 2011–2012. In total after one sampling in 2011 and 3 samplings in 2012, 42 species were identified. Our results included a new species for the Norwegian fauna, Onychiurus edinensis (Bagnall, 1935) and one species very unusual to agricultural soils, Oligaphorura ursi (Fjellberg, 1984). The most abundant species was Parisotoma notabilis (Schäffer, 1896), followed by three species of Mesaphorura Börner, 1901, two species of Protaphorura Absolon, 1901 and Isotomurus graminis Fjellberg, 2007. A high number of P. notabilis has also been found in pastures in Iceland (Gudleifsson & Bjarnadottir 2008),... |

| Organic agriculture can and should play an important role in solving future challenges in producing food. The low level of external inputs combined with knowledge on sustainablity minimizes environmental contamination and can help to produce more food for more people without negatively impacting our environment. Organic agriculture not only includes farming as a production practice but it also includes processing, trade and consumption. Nevertheless, Organic agriculture must always evolve to overcome emerging challenges. Science-based knowledge attained through dedicated research is required to strengthen organic food and farming as a means to solve future challenges. In 2010, a global discussion about Organic 3.0 was initiated to address current problems... |
