  1. 16. Improving Soil Information with Generative and Machine Learning Models

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Ebrahim Jahanshiri; [2022-06-21]
    Keywords : data augmentation; soil data; mapping; generative adversarial models; random forest;

    Abstract : Soil data observations are among the most difficult data to collect. Low sample density along with the high cost of sampling has made current soil information that are usually presented as maps, unusable for detailed applications such as modelling earth system dynamics, crop modelling, natural hazards prediction and climate change impacts.

  3. 17. Biochar from separated digestate and pig manure as soil amendment

    University essay from SLU/Dept. of Soil and Environment

    Author : Lovisa Nissen; [2022]
    Keywords : separation; screw press; incubation study; CO2 emission; N mineralization;

    Abstract : The situation in and around the Baltic Sea, with large areas with hypoxia in the sea and areas in the watershed with a high concentration of animal farms, has led to a need to increase the nutrient recycling of animal manure. High levels of phosphorus (P) in the soil lead to leaching, and by reducing the P-level in organic fertilizers, this leaching can be reduced. READ MORE

  4. 18. Biogeochemistry and Peat Properties of Restored Peatlands

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Pelle Belaieff Kronborg; [2022]
    Keywords : Drainage; Bulk density; Nitrogen; Carbon; Stable isotopes;

    Abstract : Globally, peatlands comprise the most important soil organic carbon pool storing approximately one third of all terrestrial soil carbon. Drainage can turn peatlands to net sources of carbon dioxide. Peatlands have historically been drained to increase the productivity of agriculture and forestry. READ MORE

  5. 19. Combining GHG Emissions and Soil Carbon Changes as a Single Metric to Evaluate Agricultural Policy Promoting Biomass for Biofuels

    University essay from Lunds universitet/Miljövetenskaplig utbildning; Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Author : Malin Lane; [2022]
    Keywords : Gräsvallar; klimatpåverkan; kolinlagring; jordbruk; biomassa; biobränslen.; Earth and Environmental Sciences;

    Abstract : 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. READ MORE

  6. 20. A case study of estimating Algal biomass productivity from wastewater treatment facilities in the state of Texas and possible use

    University essay from KTH/Kemiteknik

    Author : Gopi Raju Makkena; [2022]
    Keywords : Microalgae; Rotating Algal Biofilm RAB ; Flash Hydrolysis; Algal biomass; Biofertilizer; Mikroalger; roterande algbiofilm RAB ; flashhydrolys; algbiomassa; biogödsel;

    Abstract : För att hålla vattendragen och miljön rena, renas avloppsvattnet för att nå ett visst mått innan det släpps ut. Vi gjorde en fallstudie för att utvärdera metoderna som används för att behandla avloppsvatten i tre steg: primär, sekundär och tertiär i delstaten Texas, USA. READ MORE
