Presentasjon av forsøk der ulike reststraumar er testa som mat for larver. Effekten av dei ulike organiske reststraumane er målt som overleving og vekst av larver, og innhald av protein, feitt og enkelte tungmetall.

Insektfrass, restar frå produksjon av insekt til fôr og mat, kan vera ein ressurs i planteproduksjon. Frass inneheld plantenæringsstoff og har potensiale som gjødsel. Det er også forskingsarbeid som tyder på at frass kan ha ein plantestyrkande effekt. Innlegget handlar om frass som plantestyrkande middel og resultat frå forsøk.

The motivation behind this thesis is to explore the possibility for using multispectral satellite images from Sentinel-2, climatic variables, and laser data to identify oak and grey elder within deciduous tree species and differences between types of spruce. Classification is explored with the machine learning algorithm random forest, and the method is based on the Norwegian forest inventory data. Impact of narrowing down search areas in modelling, equalization of observation count between tree species and variable analysis will be analyzed in this paper. This thesis presents a promising model for classification of different spruce species for a restricted geographical area, and two less precise RF classification models for detection of oak and grey elder among deciduous trees. Climatic variables were important in classification for all models and no NDVI were important in deciduous classification. No models improved significantly after adding laser variables.

This master's thesis has explored effective strategies that can stimulate increased use of biochar within Norwegian agriculture. The primary focus was therefore to evaluate incentives that can contribute to expanding the biochar market as a soil improvement agent in the agricultural sector. Biochar, a carbon-rich material produced through the pyrolysis of biomass, has demonstrated significant potential to enhance soil health, carbon sequestration, and sustainability in the agricultural sector as a whole. However, the market faces significant obstacles that limit the product's growth in Norway. This study commences with an analysis of the current utilization of biochar in Norwegian agriculture. The identification of driving forces behind biochar development, along with the illumination of barriers in the present situation based on previous studies, is the aim. Based on the results of this study, it becomes evident that incentives play a crucial role in encouraging farmers to adopt biochar. Economic resources in the form of subsidies, grants, sale of CO2 quotas, and tax deductions have proven to be effective mechanisms for reducing the initial investment costs for farmers. Consequently, the implementation of biochar as a sustainable soil enhancement method became more attractive and economically feasible for farmers. This approach facilitates an increase in biochar usage and demonstrates a positive correlation between financial support and the proliferation of biochar use. The significance of knowledge and technical support is also acknowledged as pivotal incentives. By providing seminars, training programs, and further research, farmers can acquire more knowledge about biochar and safer practices. This valuable knowledge will contribute to the establishment of a functional market and a certification process for biochar products, effectively utilizing resources and increasing demand for biochar. The study also explores the possibility of including biochar in carbon trading and carbon offset schemes. By quantifying the carbon sequestration potential of biochar, farmers have the potential to receive carbon credits, generate new revenue streams, and optimize resource utilization. Participatory research and open communication with farmers are key components for the successful implementation of biochar subsidies and the promotion of sustainable practices. Tailoring research and incentives to farmers' needs is essential for advancing the implementation of biochar within Norwegian agriculture.

In summary, land, local and national markets are limiting and facilitatory factors of organic pig production. Only in Denmark did there appear to be organic pig farming operating at scale to meet export and national market demands. Whereas Otherwise, production and consumption was much more localized, often involving direct sales networks and contracts with local retailers and restaurants. Here, organic was just one of the key qualities to support sales with the transparency for customers being deemed more important in some instances. The result was diverse business structures with the scale and economic viability of production being limited due to the specifics of the market niche into which the pork was being sold. However, in all cases outdoor pig rearing was a value adding process that created additional important streams of revenue as part of diversified farm enterprises. The value of organic certification was questioned in some instances where the market was hyper localized and the practice of outdoor rearing and the transparency it produced for the consumer were considered to be of greater value. Economic conditions were challenging for all producers and with the exception of Denmark pigs were not the sole source of income. Where sales to retailers and local restaurants were not possible, or had not been established, direct sales networks were the principal source of consumer sales. However, maintaining direct sales networks could be challenging and involved significant work, including logistics. The high level of wellbeing and satisfaction of the farmer was a re-occuring theme which suggests that rearing pigs outdoors has mutual benefits for the farmer, the pigs and potentially the environment.

Mange som dyrker grønnsaker til direkte salg er interessert i økologiske driftsmetoder. Det er mye organisk materiale tilgjengelig i byer og tettbygde strøk. Matrester og avfall fra hager og parker kan bli til både energi og gjødsel, som kan brukes i dyrking av grønnsaker i bynære strøk. Da får vi korte verdikjeder, men hva med innholdet av tungmetaller? Beregninger viser at grenseverdier i jord vil mettes først for kobber og sink, som også er viktige mikronæringsstoffer. for planter. Jordforbedringsmidler med høyt innhold av organisk materiale, som hage-park kompost og hestegjødsel, inneholder mer tungmetaller per kg tørrstoff enn fjørfegjødsel og utråtnet matavfall.
