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 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 ... -
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 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 ... -
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 ... -
Effect of fertilization, tiller cutting and environment on plant growth and yield of European Blueberry (Vaccinium myrtillus L.) in Norwegian forest fields.
(Journal article; Peer reviewed, 2014)BACKGROUND: European blueberry (E. blueberry; Vaccinium myrtillus L.) is a natural resource demanded by the processing industry with potential of domestication. Therefore an investigation of the possibilities of partial ... -
Effect of maturity stage at harvest and kernel processing of whole crop wheat silage on digestibility by dairy cows
(Journal article; Peer reviewed, 2019)The study aimed to explore whether digestibility by cows of whole crop wheat silage harvested at two different dough stages of maturity was impaired due to its content of whole kernels. Wheat was harvested at early (ED) ... -
Effect of methyltrimethoxysilane impregnation on the cell wall porosity and water vapour sorption of archaeological waterlogged oak
(Journal article; Peer reviewed, 2019-05-02)This paper presents the water vapour sorption behaviour of degraded archaeological oak (Quercus robur L.) and the influence of methyltrimethoxysilane treatment on hygroscopicity. Wood samples (archaeological and undegraded ... -
Effect of organic grass-clover silage on fiber digestion in dairy cows
(Journal article; Peer reviewed, 2017-06)There are differences in grass-clover proportions and chemical composition between herbage from primary growth (PG) and regrowth (RG) in grass-clover leys. Mixing silages made from PG and RG may provide a more optimal diet ... -
Effect of plant type and delayed planting on growth and yield parameters of two short day strawberry (Fragaria x ananassa Duch.) cultivars in open field.
(Journal article; Peer reviewed, 2017-08-18)BACKGROUND: It is questioned if Norwegian nurseries can compete with the continental nursery industry in an open market. OBJECTIVE: Investigated how quality of certified Norwegian strawberry transplants, developed and ... -
Effect of projected land use and climate change on water quality of old woman creek watershed, ohio
(Peer reviewed; Journal article, 2021-04-04)The separate and synergistic effects of land use and climate change on water quality variables in Old Woman Creek (OWC) watershed were evaluated using a hydrological model set up in Soil and Water Assessment Tool (SWAT) ... -
Effect of replacing organic grass-clover silage from primary growth with regrowth on feed intake and milk yield of dairy cows
(Journal article; Peer reviewed, 2017-03)Under Norwegian conditions, diets based on primary growth (PG) silage typically increase milk yield compared to silage prepared from the regrowth (RG). Organic PG, dominated by immature grasses, is often high in energy and ... -
Effect of replacing organic grass-clover silage from primary growth with regrowth on N digestion in dairy cows
(Journal article; Peer reviewed, 2016-07-22)Clover proportions, and thereby chemical composition of herbage, differ between primary growth (PG) and regrowth (RG) in organic managed grass-clover fields. The characteristics of PG and RG silages suggest different ... -
Effect of Rhizome Fragmentation, Clover Competition, Shoot-Cutting Frequency, and Cutting Height on Quackgrass (Elymus repens)
(Journal article; Peer reviewed, 2017-10-17)Quackgrass is a problematic agricultural weed in the temperate zones of the world and is difficult to control without herbicides or intensive tillage. However, it may be possible to control quackgrass with less environmental ... -
Effect of riparian vegetation on stream bank stability in small agricultural catchments
(Journal article; Peer reviewed, 2018-08-21)The hydrological processes associated with vegetation and their effect on slope stability are complex and so difficult to quantify, especially because of their transient effects (e.g. changes throughout the vegetation life ... -
