1. 1. 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

3. 2. Hyperspectral and multispectral satellite data analysis of nitrogen in grazed and ungrazed tundra in Långfjället, Sweden

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Emma Dahlstedt; [2023-08-18]
   Keywords : Hyperspectral imaging; Imaging spectroscopy; Nitrogen; Reindeer; Herbivory; Tundra; Grazing;

   Abstract : Reindeer are a keystone species in the circumpolar north, where they hold great cultural and ecological importance. Continued climate change threatens the long-term sustainability of reindeer husbandry. Reindeer can affect the tundra landscape, influencing the soil nutrient cycling, including the soil nitrogen availability. READ MORE

4. 3. Vibrational signals as indicators of soil fauna health? : A novel approach to environmental monitoring of ants

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Joel Fransson Forsberg; [2023]
   Keywords : Vibrations; Formica ants; Vibrometer; Vibrational signals; Imidacloprid; Before-After-Control-Impact;

   Abstract : Soil fauna provides processes of crucial importance for ecosystem functions, but our ability to observe their actions often depend on destructive methods where the integrity of the studied environment (the soil) is compromised. In this study, I develop and test a new generation of environmental monitoring tools that utilize vibrations made by soil macrofauna to inform about their performance and health. READ MORE

5. 4. Analysis of fatty acids in fatty acid-based herbicides by gas chromatography

   University essay from Lunds universitet/Kemiska institutionen

   Author : Mohamad Abd Elwadood; [2023]
   Keywords : Analytical Chemistry; Fatty Acids; Gas Chromatography; Green Herbicides; Retention Index; Flame Ionization Detector; Mass Spectrometry; Supercritical Carbon Dioxide Extraction.; Chemistry;

   Abstract : Fatty acids-based herbicides are considered to be a green alternative to synthesized weed control products. However, the environmentally sustainable effect of those herbicides needs more investigation to be confirmed. READ MORE

6. 5. Effekten av gödsling med arGrow® granulat på barrplantors tillväxt efter de första två växtsäsongerna

   University essay from SLU/School for Forest Management

   Author : Karl-Anders Wickberg; Mattias Eliasson; [2023]
   Keywords : arginin; plantgödsling; aminosyror;

   Abstract : Tillgången på näringsämnen i marken är mycket stort i förhållande till växternas behov, men ändå är näringstillförseln ofta en tillväxtbegränsande faktor för växterna. De näringsämnen som behövs i störst mängd är kväve, som ofta är hårt bundet i svårlösliga kemiska föreningar. READ MORE
