  1. 6. Quantification of a continuous-cover forest in Sweden using remote sensing techniques

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Johan Westin; [2015]
    Keywords : digital elevation model DEM ; land cover classification; selective thinning; Physical Geography and Ecosystem analysis; remote sensing; above-ground biomass; AGB; Earth and Environmental Sciences;

    Abstract : Mapping and quantifying forest information about e.g. land cover, tree height and biomass has traditionally been a both time-consuming and labour-intensive part of forestry and forest research as field measurements typically are collected manually using handheld equipment. READ MORE

  4. 8. Comparison of soil carbon stocks in two cropping systems as affected by nitrogen application levels

    University essay from SLU/Dept. of People and Society

    Author : Esmaeil Echreshavi; [2013]
    Keywords : carbon sequestration; reduced tillage; N fertilizer; soil organic carbon;

    Abstract : This study aimed to trace possible changes in soil organic carbon (SOC) at different soil depths when treated with different levels on nitrogen fertilizer, in both conventional tillage and reduced tillage systems. The experiment was undertaken in Lönnstorp research station at SLU, Alnarp in south west of Sweden, as a part of a long term experiment. READ MORE

  5. 9. Carbon loss after forest drainage of three peatlands in southern Sweden

    University essay from SLU/Dept. of Forest Soils

    Author : Maria Gustafsson; [2001]
    Keywords : torv; mosse; kol; dekompostering; dränering; grundvattennivå; pH; CN ratio; avskogning;

    Abstract : Increased amounts of carbon dioxide in the atmosphere influence the global climate. It is therefore important to understand the effects of forestry measures on the distribution of carbon between soil, plants and atmosphere. In the present study, net changes in the peat carbon stores of mires, as a result of forestry drainage, were investigated. READ MORE
