1. Plant performance in controlled environment agriculture, the effect of different ebb and flow irrigation intervals on Brassica oleracea and Lactuca sativa
Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)Sammanfattning : Increasing productivity in controlled environment agriculture may decrease environmental footprint and increase profitability of food produced in a vertical farm. Irrigation may be a limiting factor when it comes to plant performance and relevant research is limited. LÄS MER
2. Dynamic simulation and techno-economicevaluation of a seasonally insulated hybridgreenhouse concept for subarctic climates
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : The Swedish authority for social protection and preparedness, MSB, believes that the self-sufficiency of the country must be strengthened in order to be prepared for a crisis. Presently, Sweden is only 50% self-sufficientwhich is very low compared to its neighboring countries; and it is worse the further north you go. LÄS MER
3. Biochar and hemp as peat substitutes in organic growing media : effects on nutrient availability and nutrient uptake
Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)Sammanfattning : This study aimed at evaluating the suitability of biochar and hemp as partial or complete replacement of peat in horticultural growing media, with specific emphasis on the effects on nutrient availability and plant nutrient uptake. The study was motivated by the environmental concerns surrounding the use of peat, along with a desire to explore possible uses for biochar and a crop residue from hemp cultivation. LÄS MER
4. Biochar and Hemp as Peat Substituents in Horticultural Substrates and Their Effects on Presence of Microbiota
Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)Sammanfattning : The extraction of peat has been shown to have a detrimental impact on the environment in several ways, including through emissions of greenhouse gases but also through a negative impact on fragile habitats, ecosystems, and ecosystem services. The horticultural sector is a major user of peat products and thus contributes to both emissions and habitat changes. LÄS MER
5. Urban Farming: Production comparison of Basil and Oak Leaf lettuce in two hydroponic growing systems : an industrial collaborated study in Sweden
Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)Sammanfattning : The modern agriculture of the world is facing huge challenges in terms of increasing scarcity of natural resources such as water and land. The increase in global population is not only enabling in expansion of big cities but also raising questions of accommodating and feeding this amount of population. LÄS MER
