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 EnvironmentAbstract : 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

2. Effective soil organic carbon monitoring in perennial agriculture systems - Sampling protocol development and evaluation
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : 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. Greenhouse gas emissions from peat soil thawing in spring : a comparison between fertilized and unfertilized soil
University essay from SLU/Dept. of Soil and EnvironmentAbstract : 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

4. The potential to use rhizobacteria within agricultural innovations instead of chemical inputs : taking quality and quantity of the crop into consideration
University essay from SLU/Dept. Of Plant BiologyAbstract : Plant growth promoting rhizobacteria (PGPR) are soil bacteria that occur naturally, colonize the roots of plants and can promote plant growth. PGPR isolated and used as inoculum to seed or plants is mostly marketed as a growth stimulant because it facilitates registration and reduces costs, even though PGPR may also serve as biocontrol products.

5. THE FIRST ACTIVE ACID SULFATE SOIL FOUND OUTSIDE THE BALTIC BASIN, IN VISKA VALLEY WEST COAST OF SWEDEN
University essay from Göteborgs universitet/Institutionen för geovetenskaperAbstract : Acid sulfate (AS) soils are naturally formed but are responsible for environmental problem due to its low pH. Drainage of active AS soils can lead to mobilization of harmful metals and a severe pH drop in nearby aquatic environments, which in turn may harm the ecological conditions. READ MORE
