1. 1. Impact of nitrogen availability and nitrogen structural composition on fungal enzymatic activity and growth : how nutrient availability governs response and development of three saprotrophic Basidiomycetes

   University essay from SLU/Dept. of Soil and Environment

   Author : Bella Strid; [2024]
   Keywords : nitrogen; tannins; condensed tannins; MnP; manganese peroxidase; peptidase; saprotrophic basidiomycetes;

   Abstract : Fungi excrete a wide variety of extracellular enzymes to scavenge for nutrients, such as the often scarce yet essential nutrient nitrogen. All fungi produce highly specialized hydrolytic enzymes, e.g. peptidases, that depolymerize organic molecules. READ MORE

3. 2. Effective soil organic carbon monitoring in perennial agriculture systems - Sampling protocol development and evaluation

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Maja Holm; [2024]
   Keywords : Physical geography; ecosystem science; soil organic carbon; soil sampling; perennial crops; carbon sequestration; carbon farming; Kernza™; soil organic carbon stock; Earth and Environmental Sciences;

   Abstract : Perennial agriculture systems are gaining ground as a more sustainable alternative to conventional annual agriculture, partly for their potential to increase the soil organic carbon (SOC) content. Carbon farming is another hot topic for SOC sequestration, as it creates economic incentives for farmers. READ MORE

4. 3. Greenhouse gas emissions from peat soil thawing in spring : a comparison between fertilized and unfertilized soil

   University essay from SLU/Dept. of Soil and Environment

   Author : Fanny Otterlin Karlsson; [2024]
   Keywords : agricultural soil; carbon dioxide; freeze-thaw cycles; nitrous oxide; soil temperature; water content;

   Abstract : Peat soils drained for agriculture and forestry contribute to a significant amount of greenhouse gas emissions. Nitrous oxide is a greenhouse gas with high warming potential and agriculture in general accounts for about 70 % of nitrous oxide emissions. READ MORE

5. 4. SOIL GROSS NITROGEN MINERALISATION AND FOREST GROWTH IN FOUR HEMIBOREAL FOREST STANDS IN SOUTHWEST SWEDEN

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Linnéa Eriksson; [2023-04-20]
   Keywords : soil C:N; forest production; 15N isotope dilution; gross N mineralisation; ammonium; soil carbon; soil nitrogen; root exudates; stoichiometric decomposition; boreal forests; priming; microbial C limitation;

   Abstract : Boreal and temperate forests together make up the largest terrestrial net C sink in the world. They take up carbon dioxide (CO2) from the atmosphere and store it in plant biomass and soil as they grow, making them crucial in mitigating global climate change. READ MORE

6. 5. Effects of tillage and straw treatments on earthworm abundance : study in two Swedish long-term field trials

   University essay from SLU/Dept. of Soil and Environment

   Author : Fredrik Ahlberg; [2023]
   Keywords : anecic; conventional tillage; endogeic; no-tillage; reduced tillage;

   Abstract : Earthworms have several functions in the soil, for instance redistribution of organic matter and enhancing plant available nutrients. Earthworms are divided into three ecological groups, with different functions in the soil. The groups are: anecic, endogeic and epigeic. READ MORE
