A comparative study of the implementation of organic food in school meal systems in four European countries Organic Eprints
Nielsen, Thorkild; Nölting, Benjamin; Kristensen, Niels Heine; Løes, Anne-Kristin.
Based on national reports from Denmark, Finland, Italy and Norway, describing the school meal systems and to which extent organic food is integrated there, this report identifies differences between the four countries and experiences made with organic food procurement and the dissemination of organic ingredients in school meals. Such knowledge will help to understand the possibilities and restrictions for increasing organic food in school meal systems, and to reveal the room of manoeuvre for public organic food procurement for youth in each country. In the report, similarities and differences of the national school meal systems in general are first discussed, because this context determines the scope of organic food procurement. The history and current...

Anaerobic digestion of manure - consequences for plant production Organic Eprints
Løes, Anne-Kristin; Johansen, A.; Pommeresche, R.; Riley, H..
Organic farming systems are today dependent upon fossil energy. Another challenge are soil nutrient concentrations, which may be depleted with time even in animal husbandry systems (Løes & Øgaard 2001). Anaerobic digestion (AD) of animal manure may produce biogas to replace fossil fuels, and reduce methane (CH4) emissions during manure storage. Co-digestion of substrates rich in energy increases the economic viability of the biogas plant, and off-farm substrates such as fish silage or household waste may add nutrients to the farming system. AD may also ease manure handling, while reducing the amount of weed seeds and animal pathogens. A reduced proportion of easily degraded C in the AD-manure may however impact the soil fauna/microflora and humus...

Animal manure for biogas production - what happens to the soil? Organic Eprints
Løes, Anne-Kristin; Johansen , Anders; Pommeresche, Reidun; Riley, Hugh.
Utilizing animal slurry to produce biogas may reduce fossil fuel usage and emissions of greenhouse gases. However, there is limited information on how the recycling of digested slurry as a fertilizer impacts soil fertility in the long run. This is of concern because organic matter in the slurry is converted to methane, which escapes the on-farm carbon cycle. In 2010, a study of this question was initiated on the organic research farm in Tingvoll, Norway. So far, a biogas plant has been built, producing anaerobically digested slurry to be compared with undigested slurry in perennial ley and arable crops. Effects on crop yields, soil fauna, microbial communities, soil structure, organic matter and nutrient concentrations are measured.

Ausstieg aus der zertifiziert ökologischen Landwirtschaft in Norwegen – Motivation und anschließende Wirtschaftsweise Organic Eprints
Koesling, Matthias; Løes, Anne-Kristin.
From 2002 to 2006, 7 % of the certified organic farmers in Norway opted out. A combination of a qualitative and quantitative approach was used to explore how many farmers consider to opt out, their reasons for this, and how close to or far from the organic principles they plan to manage the farm afterwards. 24 % of the certified organic farms consider to opt out in the next 5 to 10 years. The main reasons were frustration about certification, too low subsidies and premium prices, and unpredictable political frame conditions. Most plan to change to conventional farming, but more than 25 % plan to practice close to organic standards, with no or little use of pesticides and artificial fertilizers. These farmers sell about 25 % of their produce...

Bio-Lebensmittel als ein Baustein nachhaltiger Schulverpflegung – ein europäischer Vergleich Organic Eprints
Nölting, Benjamin; Løes, Anne-Kristin.
School food procurement is a hot topic. This paper is based on results from the CORE Organic I research project “innovative Public Organic food Procurement for Youth” (iPOPY) and discusses how various strategies and instruments used for organic food procurement in school meals may increase organic food consumption. School food systems and their utilisation of organic food were studied in Italy, Finland, Germany, Norway, and Denmark. These national systems were compared according to five analytical categories: type of school food service, degree of public financing, political and administrative involvement in school food procurement in general, specific support for organic school food, and development of organic supply chains. The most important factor is a...

Bio-Schulverpflegung in Italien, Finnland, Dänemark und Norwegen – Was kann Deutschland lernen? Organic Eprints
Nölting, Benjamin; Strassner, Carola; Løes, Anne-Kristin; Nielsen, Thorkild.
The policies and practice of school meal provision in Germany are currently in a dynamic transition led on by the introduction of a fulltime school system. One of the many issues being highlighted is its potential to increase the use of organic produce. The research project “innovative Public Organic food Procurement for Youth” (iPOPY; www.ipopy.coreportal.org) analyses the entire system. Results of the first comparison between Italy, Finland, Denmark, and Norway are presented here, as a background to discuss the German situation. Using a common guideline developed in iPOPY the types of school meal provision can be categorised as (a) warm lunch (IT, FI) or (b) fruit and milk subscription schemes to supplement a packed lunch (DK, NO). Italy emerges...

Industrialised chicken production is far from organic agriculture prinicples. Still of interest is a more sustainable utilisation of by-products, e.g. hydrolysation of feathers for proteins, or extraction of food grade oil from chicken bones. Such approaches were studied in the bioeconomy-project "CYCLE" (2013-2017).

Case Produsentpakkeriet.Improving the utilisation of co-streams in potato and vegetable processing Organic Eprints
Adler, Steffen A.; Løes, Anne-Kristin; Rommi, Katarina; Kambestad, G; Albrektsen, Thor-Erik.
During processing (packaging) of vegetables and potatoes, large proportions are sorted out due to minor damage or deviations from strict visual standards. Out-sorted products are poorly paid, and have a short shelf-life. Processing to increase the payment and shelf-life may support a more sustainable utilisation of these by-products. Conserving as silage is one option, which was studied in the bioeconomy-project "CYCLE" (2013-2017). Other approaches are also discussed.

Certification of organic mass catering - a need for harmonization across Europe? Organic Eprints
Lukas, Melanie; Strassner, Carola; Løes, Anne-Kristin.
To evaluate the state of the art of organic certification in out-of-home catering, a survey was carried out among relevant stakeholders in several European countries. The Council Regulation (EC) No 834/2007 about organic production specifically excludes what is called mass catering. Hence, a range of diverging systems for certification of organic catering and restaurants have been developed. This study presents opinions about a potential EU-wide harmonisation of an organic certification scheme for mass catering from relevant stakeholders. Certification bodies and other public authorities as well as stakeholders close to the catering practice were generally positive towards the idea of a harmonisation process. Several stakeholders should be involved...

Certification of public organic procurement in Denmark, Finland, Italy and Norway as compared to Germany Organic Eprints
Strassner, Carola; Lukas, Melanie; Løes, Anne-Kristin.
In the iPOPY project (innovative Public Organic food Procurement for Youth), one of the tasks was to map the challenges linked to the supply chains of organic food, and to which extent the participating countries have developed any form of certification of out-of-home food serving. For primary production and processing, regulations have been developed on the EU level. Norway, as a member of the EEA, is obliged to follow these EU regulations. However, the EU regulations on organic agriculture do not comprise catering, restaurants and other out-of-home food service. Hence, various countries have developed different systems to certify e.g. restaurants wanting to market their organic menus. This report describes the systems in Denmark, Finland, Italy, Norway...

Changes in the nutrient content of agricultural soil on conversion to organic farming, in relation to farm level nutrient balances and soil contents of clay and organic matter. Organic Eprints
Løes, Anne-Kristin; Øgaard, Anne Falk.
Agricultural soil on 12 farms converting to organic farming was sampled in 1989 and 1995 at the same sample points. Concentrations of plant-available (-AL) P, K, Ca and Mg, HNO3-soluble K, tot- N, tot-C and pH were measured in two layers. The average K-AL concentration and pH were reduced in both layers. The average P-AL concentration was reduced in the topsoil. K-AL and P-AL increased in samples with low concentrations and decreased in samples with high and very high concentrations in 1989. The total N concentration increased in the subsoil. Tot-N and tot-C increased in top- and subsoil with a low organic matter content. The net import of P, calculated by farm level nutrient balances, was negatively correlated to the change in kg P-AL per hectare in the...

Collembola in grassland – included in the new project SoilEffects Organic Eprints
Pommeresche, Reidun; Løes, Anne-Kristin.
Little is known about Collembola in arable soil, at least in Norway. Recently, a study including this group has been initiated in a Norwegian field experiment Soileffects). Collembola (springtails) are a group of small animals (1-3 mm) living in vegetation,litter and in the pores and caves in the soil to a depth of ca 15 cm. They are important decomposers of dead plant material, eating fungi, algae and microorganisms in soil and on organic debris. Their grazing and decomposing activity contribute significantly to the nutrient circulation in the soil. The name springtail refers to a furca on their back, usually folded in under the body, but released in need of a rapid escape. In one jump, Collembola can jump more than 50 times their own body length. In...

Concentrations of soil potassium after long-term organic dairy production Organic Eprints
Løes, Anne-Kristin; Øgaard, Anne Falk.
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...
