Abstract
Denne rapporten omhandlar resultat frå kartlegging av næringsstatusen i norske eplehagar. Jord,- blad og fruktprøvar vart samla inn frå ulike eplehagar på Aust- og Vestlandet med variasjon i jordart, innhald og type organisk materiale i åra 2018-2020. Føremålet var å studera samanhengane mellom plantefysiologiske sider i epletreet relatert til jorda, treveksten, avling og fruktkvalitet. Resultat frå det treårige studiet om verknaden av gjødselpraksisar på opptak av mineral i blada, avling og fruktkvallitet hjå ulike eplesortar frå fire regionar er samla i denne rapporten. This report is summarizing results from a survey analyzing the nutrient levels in fruit trees and soil in four fruit growing regions in Norway during the seasons 2018-2020. The aim was to study the relationship between main plant physiological principles in the tree, related to the soil, tree growth, yield, fruit quality, and fruit storage. The results of a three-year study of apple tree fertilization practices on orchard soil fertility, leaf mineral composition, apple tree yields and fruit quality of several apple cultivars in four main apple producing regions in Norway are compiled in this report.

Abstract
The book discusses scientific, technical, and sociological aspects of sustainable agricultural value chains, focusing on coffee and tea production. The book advocates a value-chain strategy and highlights the importance of tracking the effects of climate change. Increasing the amount of value-added products via irrigation is critical to combating climate change and achieving sustainable development. Furthermore, blockchain technology has the potential to transform agricultural business models and supply chain networks.

In Europe, turbot aquaculture has a high potential for sustainable production, but the low tolerance to fishmeal replacement in the diet represents a big issue. Therefore, this study investigated the effects of more sustainable feed formulations on growth and feed performance, as well as nutritional status of juvenile turbot in recirculating aquaculture systems. In a 16-week feeding trial with 20 g juvenile turbot, one control diet containing traditional fishmeal, fish oil and soy products and two experimental diets where 20% of the fishmeal was replaced either with processed animal proteins (PAP) or with terrestrial plant proteins (PLANT) were tested. Irrespective of diets, growth performance was similar between groups, whereas the feed performance was significantly reduced in fish of the PAP group compared to the control. Comparing growth, feed utilisation and biochemical parameters, the results indicate that the fish fed on PAP diet had the lowest performance. Fish fed the PLANT diet had similar feed utilisation compared to the control, whereas parameters of the nutritional status, such as condition factor, hepato-somatic index and glycogen content showed reduced levels after 16 weeks. These effects in biochemical parameters are within the physiological range and therefore not the cause of negative performance. Since growth was unaffected, the lower feed performance of fish that were fed the PAP formulation might be balanced by the cost efficient formulation in comparison to the commercial and the PLANT formulations. Present study highlights the suitability of alternative food formulation for farmed fish.

Industrial kelp aquaculture is under development in Nordic countries including Norway. Kelps are a rich source of nutrients, taste and other bioactive substances with a large potential in food applications. There are some critical challenges for the food industry to a broader use of this new resource such as the reduction of iodine and potential allergens present. SusKelpFood is a new collaborative research project which primary objective is to enable innovative solutions for the sustainable production of safe, nutritious and flavourful ingredients from cultivated kelps for the food industry. SusKelpFood draws on key expertise from Nordic (Norway, Denmark and Iceland) research institutions, a leading actor of the food industry in Scandinavia and kelp producers to achieve this goal. The participants will test and develop targeted and energy-efficient processes including fermentation under different conditions, innovative drying and dewatering techniques (e.g. pulse-electric field, microwave-assisted drying) to conserve and prepare cultivated kelps for large-scale food applications in a sustainable way. Laboratory techniques will be applied to document the food safety (presence of contaminants, iodine, food allergens), nutritional and sensory profiles, and flavor-active substances of kelp ingredients produced from different processes. Consumer surveys, interviews and testing of product prototypes containing kelp ingredients will provide valuable information on consumer behavior for this type of products. The knowledge generated during SusKelpFood will promote future-oriented solutions for a broader inclusion of sustainably produced kelp in manufactured food products. The SusKelpFood project is financed by the Research Council of Norway and runs for 3 years from 2022 to 2024.
