1. Pyrolysis of Municipal Sewage Sludge to get a phosphorus rich char residue for soil improvement
Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : Sewage sludge is a byproduct of wastewater treatment plants. It is a kind of waste. however, it contains several valuable nutrients like phosphorous and nitrogen that are used to rich the soil as a fertilizer compound. LÄS MER
2. Companion crops in winter oilseed rape : effects on nitrogen concentration, biomass, and prevalence of weeds at the end of autumn growth
Master-uppsats, SLU/Dept. of Crop Production EcologySammanfattning : Intercropping can be used as a management system to promote higher yield as well as less weeds,diseases, and insect damage. Legumes are a commonly used companion crop (CC) in intercropping due to the benefit of nitrogen (N) fixation. LÄS MER
3. REINDEER GRAZING IN A NORTHERN BOREAL FOREST : Seasonal and reindeer-induced changes in nutrient availability and soil temperature
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Soil nutrient availability is a key component to understanding the boreal ecosystems, as it directly relates to plant productivity and ecosystem diversity. There is however little known about how the nutrient availability changes seasonally in the boreal forest. LÄS MER
4. Optimizing nitrogen fertilization in ley : Evaluating the usage of N-sensor and other tools for optimized nitrogen fertilization
Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and EnvironmentSammanfattning : Nitrogen is an essential nutrient for plant growth. It has several functions in the plant and a lack of nitrogen can cause severe yield losses. LÄS MER
5. Assessing the effect of Fusarium graminearum inoculation on the root structure of Swedish winter wheat cultivars (Triticum aestivum
Master-uppsats, SLU/Dept. of Crop Production EcologySammanfattning : Several diseases attack the wheat crop and reduce the yield, such as root disease, which causes a tremendous loss in wheat production. Root rot has a variety of causal agents, such as nematodes, viruses, and bacteria, but the most common pathogens causing wheat root rot are oomycetes and fungi. LÄS MER
