Land use, land-use change and forestry (2005) as presented in Chapter 2 of this report. Limited availability of nitrogen, along with relatively low summer temperature and short growing season, acts as a limiting factor for the growth of Nordic forests (Linder 1987, Kellomaki etai. Thus nitrogen fertilization is considered an important forest management practice in the Nordic regions. It enhances the forest growth and thus increases the carbon sequestration particularly in less fertile sites (Norden 2013, Hyvonen etai.
