1. Effekten av gödsling med arGrow® granulat på barrplantors tillväxt efter de första två växtsäsongerna
Kandidat-uppsats, SLU/School for Forest ManagementSammanfattning : 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. LÄS MER
2. Nutrient flow on agroforestry farms in the province of Son La in northwest Vietnam
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/VindenergiSammanfattning : 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. LÄS MER
3. How is carbon stored in boreal forest soils? - A method development which investigates at what protein concentration ferrihydrite and goethite are saturated.
Kandidat-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)Sammanfattning : 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. LÄS MER
4. Plant community responses to 15 years of nitrogen and phosphorus fertilization along an elevational gradient in the subarctic tundra
Master-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : 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. LÄS MER
5. Review of pH recommendations for soilless cultivation systems
Kandidat-uppsats, SLU/Dept. of Crop Production EcologySammanfattning : 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. LÄS MER
