1. 1. The potential nitrous oxide emissions in a permanent grassland chronosequence

   University essay from SLU/Dept. of Forest Mycology and Plant Pathology

   Author : Sandra Lillsjö Kronblad; [2023]
   Keywords : nitrous oxide emission; permanent grasslands; denitrification; nitrous; reen house gas; agriculture;

   Abstract : As a part of a larger project (Belowground biodiversity of grasslands – conservation needs and potential to promote sustainable agriculture), this study aims to investigate potential nitrous oxide (N2O) emissions and microbial gene abundances needed for the production (nirS and nirK) and reduction (nosZI and nosZII) of nitrous oxide in soil of permanent grasslands of various age. Thegrasslands have at different times been converted to permanent grasslands and are of interest because of the possibility to shed more light about the passage of time’s affects on the soil microbialcommunities and their activity.
