Biochar for N2O mitigation and improved delivery and retention of mineral nitrogen in compost and soil
Weldon, Simon (PhD Thesis;2022:15, Doctoral thesis, 2022)Biochar is a promising technology for simultaneously storing carbon in soils, improving crop yields and reducing greenhouse gases. In the last 20 years, research efforts into biochar and its application to soils have been ... -
Constraints for carbon degradation in subarctic thawing peatland permafrost in Northern Scandinavia
Kjær, Sigrid Trier (Master thesis, 2021)Permafrost soils are globally under pressure and subject to climate change induced permafrost thawing. Peat plateaus are found in peatlands with discontinuous permafrost and store large quantities of carbon (C). They are ... -
Mitigation of greenhouse gas emissions by pH management of agricultural soils in Norway
Vekic, Teodora Todorcic (PhD thesis;2023:2, Doctoral thesis, 2023)Liming has been and still is used to neutralize soil acidity, improve soil nutrient availability, increase yields, and recently it has been recognized as a possible nitrous oxide (N2O) mitigation tool for arable soils. ... -
Nitrogen turnover and N2O emissions as a function of edaphic and hydrological conditions in subtropical forests of South China
Yu, Longfei (PhD Thesis;2016:81, Doctoral thesis, 2017-07-12)Forests in the Chinese subtropics receive large amounts of nitrogen (N) from the atmosphere, both as ammonium (NH4 +) and nitrate (NO3 -). Many of these forests are considered to be “N-saturated”, i.e. are not able to ... -
Nitrous oxide emission and turnover in arable cropping in South East Norway
Russenes, Aina Lundon (PhD Thesis;2020:18, Doctoral thesis, 2020)Nitrogen is essential for all life on Earth. With an increasing global population, the use of reactive nitrogen has increased over the last century, resulting in increasing nitrogen pollution. Leaching of nitrate (NO3-) ... -
Organic matter decomposition and mercury mobilization in thawing subarctic permafrost peat plateaus
Nedkvitne, Nora (Master thesis, 2021)Mercury (Hg) is a highly potent neurotoxin which is naturally present in the environment. A vast amount of the global Hg is stored in Arctic permafrost soils, immobilized by complexation with organic matter (OM). With an ... -
Source separating sanitary systems : energy efficient treatment of blackwater and minimizing greenhouse gas emissions

Subsoil nitrogen utilization and N₂O formation in Norwegian grass-clover forage systems
Byers, Erin Elizabeth (PhD thesis;2023:7, Doctoral thesis, 2023)Value creation in Norwegian agriculture is primarily based on milk and meat production, which depend in part on perennial grassland-based forage production. Roughly 60% of the fully cultivated land in Norway is used for ...
