1. En hållbart intensifierad slåttervall med vitklöver : en litteratursammanställning
Kandidat-uppsats, SLU/Dept. of Crop Production EcologySammanfattning : Fördelarna med att inkludera vall i växtföljden är många, till exempel kolinlagring, markförbättrande egenskaper och ogräsbekämpning. Intresset för odling av vall ökar när det finns fler avsättningsmöjligheter och ses som ett medel för att uppnå en hållbar intensifiering av odlingssystemet. LÄS MER
2. IMPLEMENTATION OF NITROGEN RECOVERY AT WASTEWATER TREATMENT PLANTS TO COMPLEMENT ARTIFICIAL FERTILISER PRODUCTION : An investigation of the nitrogen recovery potential, energy consumption and environmental impacts at Kungsängens wastewater treatment plant in Västerås, Sweden
Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknikSammanfattning : As Kungsängens wastewater treatment plant is considering a move, it opens up a possibility to implement nitrogen recovery technologies that comply with current and future legislative requirements. Nitrogen recovery offers simultaneous treatment of wastewater and collection of concentrated ammonia products for fertiliser production. LÄS MER
3. Opportunities for increased nutrient recovery at centralised wastewater treatment plants through urine separation
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Municipal wastewater contains a significant amount of nutrients such as phosphorus (P) and nitrogen (N). Therefore have the interest of recovering these nutrients at wastewater treatment plants (WWTP) increased. Nutrient recovery would generate revenue for the WWTP, as it is possible to sell the products as fertiliser. LÄS MER
4. Fertiliser derived from human urine : novel media for alkaline urine dehydration
Master-uppsats, SLU/Dept. of Energy and TechnologySammanfattning : Every year, each human excretes approximately 4 kg of nitrogen, 1 kg of potassium and 0.3 kg of phosphorus through their urine. In conventional wastewater treatment, these nutrients are usually not recovered for agricultural production, although they can enhance plant growth. LÄS MER
5. No-till grain legume production in organic farming : constraints, possibilities and potential agronomic practice
Kandidat-uppsats, SLU/Dept. of Crop Production EcologySammanfattning : Today’s agriculture is often specialised, and relies on pesticides, synthetic fertiliser and tillage. Tillage, especially ploughing, has shown to have a negative impact on climate, soil health and -biodiversity. An alternative is no-tillage, a practice that leaves the soil almost undisturbed except for minimal impact during sowing. LÄS MER
