ecochange: An R-package to derive ecosystem change indicators from freely available earth observation products
(Peer reviewed; Journal article, 2022-10-11)1. Spatial resources accessible for the derivation of biodiversity indicators of the class ecosystem structure are sparse and disparate, and their integration into computer algorithms for biodiversity monitoring remains ... -
Ecological status assessment of clay rivers with naturally enhanced water phosphorus concentrations
(Peer reviewed; Journal article, 2022-08-10)The species composition of benthic algae changes as water phosphorus concentrations increase, and these changes can be used for ecological status assessment according to the Water Framework Directive. Natural background ... -
Economic optimal nitrogen rate variability of maize in response to soil and weather conditions: Implications for site-specific nitrogen management
(Peer reviewed; Journal article, 2020-08-21)The dynamic interactions between soil, weather and crop management have considerable influences on crop yield within a region, and should be considered in optimizing nitrogen (N) management. The objectives of this study ... -
Economic performance and efficiency determinants of crop-producing farms in Norway
(Journal article; Peer reviewed, 2018)Purpose – The purpose of this paper is to explore the economic performance of Norwegian crop farms using a stochastic frontier analysis. Design/methodology/approach – The analysis was based on a translog cost function and ... -
Ecotoxicity attenuation by acid-resistant nanofiltration in scandium recovery from TiO<inf>2</inf> production waste
(Peer reviewed; Journal article, 2023-04-04)The lack of high-grade scandium (Sc) ores and recovery strategies has stimulated research on the exploitation of non-ore-related secondary sources that have great potential to safeguard the critical raw materials supply ... -
Ecotoxicity of nanomaterials used for remediation
(Chapter, 2019)Remediation using nanoparticles depends on proper documentation of safety aspects, one of which is their ecotoxicology. Ecotoxicology of nanoparticles has some special features: while traditional ecotoxicology aims at ... -
Ecotoxicological effects on earthworms of fresh and aged nano-sized zero-valent iron (nZVI) in soil
(Journal article; Peer reviewed, 2012-09)Although nano-sized zero-valent iron (nZVI) has been used for several years for remediation of contaminated soils and aquifers, only a limited number of studies have investigated secondary environmental effects and ecotoxicity ... -
Educational Strategies in Cultural Landscapes. Are we complying with the Faro Convention?
(Peer reviewed; Journal article, 2022-07-22)The Faro Convention underlined the importance of educational initiatives related to heritage. This paper focuses on the educational dimension of landscape, as a means to better facilitate its social acceptance and hence ... -
Effect of acid based additive treatment of low dry matter grass crops on losses and silage quality in bunker silos
(Peer reviewed; Journal article, 2021-05)The large surface area of bunker silos imposes challenges with heating caused by plant respiration during initial ensiling. This study aimed to explore if application of a formic- and propionic acid-based additive would ... -
Effect of anaerobic digestion of manure before application to soil – benefits for nitrogen utilisation?
(Peer reviewed; Journal article, 2021-03-03)Purpose Anaerobic digestion produces renewable energy, biogas, from organic residues, but also digestate, a valuable organic fertiliser. Previous studies have indicated that digestate contains ample plant available nitrogen ... -
Effect of calcareous and siliceous amendments on N2O emissions of a grassland soil
(Peer reviewed; Journal article, 2023-05-19)Liming of acidic agricultural soils has been proposed as a strategy to mitigate nitrous oxide (N2O) emissions, as increased soil pH reduces the N2O/N2 product ratio of denitrification. The capacity of different calcareous ... -
The effect of climate variability in the efficacy of the entomopathogenic fungus Metarhizium acridum against the desert locust Schistocerca gregaria
(Peer reviewed; Journal article, 2022-05-09)Despite substantial efforts to control locusts they remain periodically a major burden in Africa, causing severe yield loss and hence loss of food and income. Distribution maps indicating the value of the basic reproduction ... -
The Effect of Combined Drought and Temperature Stress on the Physiological Status of Calcareous Grassland Species as Potential Candidates for Urban Green Infrastructure
(Peer reviewed; Journal article, 2023-05-16)Nature-based solutions are promising for climate adaptation and environmental management in urban areas, but urban conditions are stressful for vegetation. In particular, the interaction of drought and high temperatures ... -
Effect of combined seasonal coverage on northern production of strawberry (Fragaria ananassa Duch)
(Journal article; Peer reviewed, 2017)Two field trials with five strawberry cultivars planted on a woven black polyfibre ground cover sheet with or without translucent sheet plant coverage during winter and the growing season as combined treatments were started ... -
Effect of composting and vermicomposting on potentially toxic element contents and bioavailability in sewage sludge digestate
(Peer reviewed; Journal article, 2023-02)Vermicomposts and composts prepared from sewage sludge digestate and additives (spent mushroom compost, straw, biochar) after 43 days pre-composting followed by 90 days vermicomposting with Eisenia fetida or by compost ... -
The effect of diammonium phosphate and sodium silicate on the adhesion and fire properties of birch veneer
(Peer reviewed; Journal article, 2019-09-24)In built environments the combustibility of wood is a great concern, which limits the use of wood as a building material due to legislation. The reaction-to-fire properties of wood can be altered with the use of fire-retardant ... -
