6. Identifying molecular markers for breeding a future oil crop, Lepidium campestre
Master-uppsats, SLU/Dept. of Plant Breeding (from 130101)Sammanfattning : The cold hardy novel oil- and cover crop Lepidium campestre is currently being domesticated as a potential oil crop for the Nordic region. To achieve this objective, multiple traits have previously been identified as desirable to improve, including seed oil content and composition, and glucosinolate (GL) content. LÄS MER
7. Combining GHG Emissions and Soil Carbon Changes as a Single Metric to Evaluate Agricultural Policy Promoting Biomass for Biofuels
Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning; Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)Sammanfattning : Incorporating a multi-year grass ley into an arable crop rotation can increase soil organic carbon stocks, reduce carbon emissions and provide feedstock for biogas. This thesis set out to study how a policy promoting agricultural biomass for biogas impacts GHG emissions and carbon sequestration on a regional level over a temporal scale of 20 years. LÄS MER
8. Effects of cover crops on nitrous oxide (N2O) emissions in cereal cropping
Master-uppsats, SLU/Dept. of EcologySammanfattning : More than 60% of anthropogenic nitrous oxide (N2O) emissions are attributed to agricultural activities. N2O production in soils highly depends on the N availability along with other factors such as soil moisture content, which provide suitable conditions for nitrification and denitrification. LÄS MER
9. Complete removal of biomass from oilseed radish as a cover crop decreased nitrous oxide emissions
Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)Sammanfattning : One of the many benefits of utilizing cover crops in crop rotations is their carbon sequestrating effect. However, frost-sensitive cover crops could emit high levels of the potent greenhouse gas nitrous oxide. LÄS MER
10. Effekten av olika brukningsmetoder på kolinlagring i åkermark
Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning; Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)Sammanfattning : Increased carbon sequestration in agricultural land is an important measure to reduce global warming. Since the soil is a large carbon sink, a small change in the soil organic carbon (SOC) stocks can make a substantial difference to the carbon dioxide content in the atmosphere. LÄS MER
