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.

Wood is a renewable resource, but not an unlimited one. Circular use of wood can mitigate greenhouse gas emissions and spare virgin resources. To plan for the circular use of building materials, it is important to study the availability of building materials in the built environment and the materials liberated during renovation. There exist multiple studies on so-called material intensities in buildings (Amini et al., 2024; Arceo et al., 2021; Fishman et al., 2024; Nasiri et al., 2023), but few evaluate the material intensities before and after renovation. In this study, we try to fill the knowledge gap by preforming a case study of a log house from the 19th century, upgraded to a student residence satisfying the building requirements for new Norwegian buildings.

Background: Soil microbes play a central role in nutrient recycling in soils: however, the genetic mechanisms governing their responses to long-term fertilization remain poorly understood. While the agronomic benefits of long-term fertilization are well-documented, the genetic mechanisms and ecological processes underlying microbial community responses to different fertilization regimes remain poorly understood, particularly in unique soil systems such as black soils (Mollisols), which are critical for global food security. A deeper insight into how organic and inorganic fertilizers influence microbial assembly, functional potential, and community stability is essential for developing sustainable soil management practices. Results: This study deciphers microbial assembly mechanisms, functional gene dynamics, and community restructuring in black soils subjected to 44 years of chemical fertilizer (CF), manure amendment (M), and integrated chemical fertilizer with manure (CFM) treatments. Results revealed that CF significantly enhances functional gene abundance related to carbon (C) degradation (e.g., starch, cellulose, chitin and lignin) and nitrification, accelerating the conversion of recalcitrant C to labile C pools and ammonium to nitrate. Conversely, M and CFM treatments promote microbial diversity and stability while decelerating nutrient transformation processes. In addition, microbial assembly mechanisms shift from stochastic to deterministic processes with long-term fertilizer application in CF. The structural equation modeling (SEM) indicated that soil chemical properties shape both the diversity and composition of taxonomic and functional gene communities which subsequently regulate microbial -mediated nutrient cycling processes and crop yield. Conclusions: Our findings highlight the trade-offs between microbial functional potential and community stability under contrasting fertilization strategies, emphasizing the need to integrate microbial metrics into sustainable land management frameworks.
