1. 6. 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

3. 7. Soil Organic Carbon in Boreal Agricultural Soil : Tillage interruption and its effect on Soil Organic Carbon

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

   Author : Hilda Alfredsson; [2023]
   Keywords : soil organic carbon; agriculture; tillage interruption; carbon sequestration;

   Abstract : Farmers have been disrupting the carbon cycle ever since humans started converting forests to agricultural lands. But are there farming practices that can be applied to increase the carbon storage in the soil and subsequently counteract increasing carbon dioxide levels in the atmosphere? In this study I investigate if soil organic matter (SOM) and soil organic carbon (SOC) change with longer interruption between tillage events. READ MORE

4. 8. How is carbon stored in boreal forest soils? - A method development which investigates at what protein concentration ferrihydrite and goethite are saturated.

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

   Author : Louise Berild; [2023]
   Keywords : Soil nitrogen; soil carbon; boreal forest; ectomycorrhizal fungi; decomposition; adsorption; ferrihydrite; goethite; Earth and Environmental Sciences;

   Abstract : Boreal forests store the majority of their carbon in the soil and play an important role in the global carbon cycle. However, the mechanisms that control carbon storage in boreal soils are not well understood. READ MORE

5. 9. Soil Carbon Stocks in Old Growth Forest : Drivers of variability in soil organic carbon stocks in old growth boreal forests

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

   Author : Elis Ingvarsson; [2023]
   Keywords : old growth forest; boreal; soil organic carbon stocks; climate gradient;

   Abstract : Soil organic carbon (SOC) is the largest carbon pool in terrestrial ecosystems, which plays an important role in climate change by regulating atmospheric carbon dioxide. Sweden’s forest management has led to a decrease in old growth forests. This change in land use can affect SOC levels in these forests. READ MORE

6. 10. Legacy effects of temperature alterations on microbial resistance and resilience to drying and rewetting

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Franklin Lee Harris; [2023]
   Keywords : microbial ecology; soil; carbon dynamics; high latitudes; climate change; moisture stress; isotopes; respiration; trait based ecology; soil microbes; Environmental Changes in High Latitudes EnCHIL ; Earth and Environmental Sciences; Biology and Life Sciences;

   Abstract : With warming in soils due to climate change, a series of secondary factors arise, which have multifaceted effects on soil microbial communities. Of these, alterations to soil moisture are among the most crucial to understanding how microbial functions will change in the face of climate change. READ MORE
