Publikasjoner
NIBIOs ansatte publiserer flere hundre vitenskapelige artikler og forskningsrapporter hvert år. Her finner du referanser og lenker til publikasjoner og andre forsknings- og formidlingsaktiviteter. Samlingen oppdateres løpende med både nytt og historisk materiale. For mer informasjon om NIBIOs publikasjoner, besøk NIBIOs bibliotek.

In the Nordic countries several composting plants for source separated organic household waste (SSOW) experience problems with slow degradation of organic matter and stagnation of temperature around 45-50ºC in early phases of the composting process. The process problems have been connected to high content of organic acids and domination of fermenting organisms in the waste. To break the domination of fermenting organisms, measures must be taken to develop an aerob, thermophilic bacteria population. We have studied how lime addition and adjustment of the SSOW:bulking agent (BA)-ratio influence the development of thermophilic conditions and high-rate respiration in SSOW-based composting.

Grunnlaget for en høy brokkoliavling sikres ved god N-tilgang i perioden fra to til seks uker etter planting, når hodeanlegget dannes. I siste del av dyrkingsperioden bør N-tilførselen begrenses for å stimulere til intern overføring av N fra stengler og blad til brokkolihoder.

Increasing levels of Fusarium mycotoxins have been recorded in Norwegian cereals during the last few years. In 2004, unusual high levels of deoxynivalenol (DON) were recorded, in particular in oats (e.g. 25-30 000 ppb) and some alarming levels of T-2 and HT-2 were recorded in 2005, also in oats. Due to the lack of effective control measures, FHB and mycotoxin contamination poses a significant threat to the yield and quality of cereals. Today only a very limited number of check samples of grains used for food and fodder are tested for mycotoxin content. To reduce the risk of contaminated cereals entering the food and feed processing chain, a four-year project (2006-2009) has been started, with the aim to develop a strategy for identification and discarding of unsuitable grain lots. Because there will be impracticable to analyse every lot the basis for a three-step screening system will be established: 1 - Development of prediction models based on information about effects of agronomic/cultivation practice and climatic conditions, for selection of putative `high-risk" fields/lots; 2 " Selection of a suitable and rapid testing method with capacity to screen a large number of samples for relevant mycotoxins at low costs, for testing of `high-risk" lots; 3 " Chemical toxin analyses of grain lots found to be highly contaminated in step 2. Fusarium avenaceum , F. culmorum, F. poae and F. tricinctum have been the most frequently recorded Fusarium species on cereals in Norway for many years. However, more recently also F. graminearum has occurred more frequently and F. langsethia has been detected especially in oats. Investigations will be carried out to see if there has been a change in the composition of Fusarium species.
