1. 1. 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

3. 2. Nutrient flow on agroforestry farms in the province of Son La in northwest Vietnam

   University essay from Uppsala universitet/Vindenergi

   Author : Tula Strotz; [2023]
   Keywords : Agroforestry; contouring grass rows; Guinea grass; nutrient losses; Vietnam; Gräsbarriärer; Höglandsodling; näringsförlust; Träjordbruk; Vietnam;

   Abstract : The population in the high mountains of the northwest provinces of Vietnam belongs to the poorest population in the country. Among the reasons behind this are the high frequency of minority groups in the region and the infertile soils of the steep slopes. READ MORE

4. 3. 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. 4. Plant community responses to 15 years of nitrogen and phosphorus fertilization along an elevational gradient in the subarctic tundra

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

   Author : Gaya Ten Kate; [2023]
   Keywords : arctic tundra; climate change; fertilization; nitrogen; phosphorus; plant community composition; species richness; Simpson’s diversity; Shannon-Wiener diversity; elevational gradient;

   Abstract : Climate change in the Arctic has profound effects on tundra vegetation, directly through increasing temperatures and indirectly through changes in plant community composition and nutrient cycling. Fertilization experiments are widely used to study the effects of increased nutrient availability on arctic tundra vegetation. READ MORE

6. 5. Review of pH recommendations for soilless cultivation systems

   University essay from SLU/Dept. of Crop Production Ecology

   Author : Elric Fabricius; [2023]
   Keywords : soilless cultivation; hydroponics; aeroponics; NFT; nutrient film technique; DWC; deep water culture; pH; nutrient solution; speciation; availability; biomass production;

   Abstract : Our human population is growing, and with that, so is our demand for food, food that today still is not a guarantee for all of us. To help increase global food security, the diversification of our food production through the implementation of soilless, hydroponic cultivation systems has been suggested. READ MORE
