The main objective of this scoping document, is to deliver an overall roadmap for the EU commission, targeting the soil mission objective “conserving and increasing soil organic carbon stocks”. The objective addresses the importance of maintaining, or in many situations increasing the soil organic carbon stocks. The soil organic carbon stock is often declining, and vulnerable to further losses due to intensive management and climate change. The soil mission objective aims at identifying actions that can limit the current carbon losses from cultivated soils and preferably reverse it to a rate of 0,1 - 0,4% increase per year (European Commission n.d.). The mission's objectives are relevant not only for supporting the aim to improve soil health by 2030, but also for the member states to become carbon neutral by 2050 (European Commission, n.d.). This think tank addresses the importance of maintaining, or in many situations increasing the soil organic carbon stocks by addressing the impacts of: • Management - Forestry management - Agronomic and land use managements - Climate change and adaptation technologies - Biodiversity and soil health • Societal - Urbanization and circular economy - Education and awareness raising - EU-footprints on SOC-stocks outside EU • Technical - Soil carbon measuring and monitoring In general, changes in soil carbon stocks are slow and management effects will vary depending on climate zones and soil types. Dialog and interaction is essential with all relevant stakeholder including those who own or manage land, agronomic advisors (both governmental and commercial), agricultural supply companies, policy makers, those involved in the food supply chain, and others, for the successful implementation of soil carbon management technologies. Practitioners holds essential knowledge and experience about their own land, and mutual knowledge and practice exchange, will facilitate and stimulate the necessary engagement for innovative technology implementation within the various aspects of soil carbon stocks and improvement of soil health in general.

We examine the association between beer prices and the inherent characteristics of beers within the traditional price hedonic framework. Using a large-scale Norwegian data set with more than 9000 individual beer products from several production countries, we find that alcohol content has a strong, positive, and significant effect on the retail price of beer. In contrast, the effect of expert quality rating on beer price appears to be of only small to moderate importance. We also find significant and substantially important price differences between production countries. Finally, there is effect heterogeneity (i.e. interaction effects) for both alcohol content and quality rating with respect to production country. For example, the association between alcohol content and price is larger in Norway and Germany than in most of the other production countries in the data.

The aim of this work was to investigate the influence of two locations and seven cultivars on the profiling of metabolites in organically grown plums (Prunus domestica L.) fruit in Norway. P, K, and Ca were most abundant in the studied fruits, while Ba and Sr formed a clear line between the locations. The most abundant sugars were glucose, fructose, sucrose, and sorbitol, which together accounted for up to 97.00%. Quinic acid and malic acid were the predominant organic acids, while chlorogenic acid, rutin, and kaempferol-3-O-glucoside were the most abundant polyphenols. Plums from Ullensvang were characterized by a higher content of minerals, sugars, organic acids, total polyphenol content (TPC), and radical scavenging activity (RSA), while plums from Telemark had a higher content of quantified polyphenols. The cultivar ‘Mallard’ had the highest mineral and radical scavenging activity, ‘Opal’ had the sweetest fruit, ‘Jubileum’ had the highest acidity, ‘Excalibur’ had the highest TPC content, and ‘Valor’ stored the highest content of quantified polyphenols, especially chlorogenic acid. These results provide comprehensive information on the chemical profiles of selected plum cultivars, suggesting that organic plums are a rich source of beneficial compounds that can have a positive impact on human health.
