  1. 1. Using Sentinel-2 Satellite Images to Estimate Traits of Forage Grasslands

    Master-uppsats, SLU/Dept. of Agricultural Research for Northern Sweden

    Författare :Niklas Zeiner; [2021]
    Nyckelord :Remote sensing; Forage grasslands; Sentinel-2; Dry matter yield; Canopy average height; Total leaf chlorophyll content; Partial least squares; Support vector machines;

    Sammanfattning : In this project, regression models based on data from field measurements and spectral information extracted from satellite imagery were used to estimate traits of forage grasslands; dry matter yield, canopy average height and total leaf chlorophyll. Four fields at SLUs Röbäcksdalen field station were sampled on 22 occasions and a total of 198 samples, including measurement of the highest plant, canopy height, leaf chlorophyll content, canopy spectral reflectance and biomass were collected.

  3. 2. Development of methods for detection of radioactive aerosols of special importance for the ESS facility

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Martin Carlström; [2021]
    Nyckelord :alpha spectrometry; radioactive aerosols; spectrum simulation;

    Sammanfattning : With the construction of the European Spallation Source (ESS) steadily approaching the operational phase, an environmental monitoring program will soon be implemented with the purpose of monitoring emissions. With regard to radiation safety, it is highly important to monitor alpha emitting radionuclides in aerosol form. LÄS MER

  4. 3. En alléodlings inverkan på markfaunan i jordbruksmark

    Kandidat-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Alva Johansson; [2019]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : A transition from conventional to organic agricultural practices has been shown to have positive impacts on soil and ground-living fauna. Organic farming manure is on the other hand harder for the crops to absorb than conventional fertilizers, which results in more pollutants and unsatisfactory yields. LÄS MER

  5. 4. Marktäckande material som åtgärd för minskat fosforläckage från rasthagar för värphöns

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and Environment

    Författare :Ebba Hellstrand; [2019]
    Nyckelord :utehöns; fosforbindningsförmåga; punktbelastning;

    Sammanfattning : Today there is a knowledge gap about phosphorus leakage from free range laying hens, and because of that a pilot project is ongoing since 2016 with scientists at The University of Agricultural Sciences (SLU), Research Institutes of Sweden (RISE) and also advisors in order to investigate the nutrient load from free range laying hens. My thesis have been conducted within this project, and I have chosen to focus on phosphorus leakage. LÄS MER

  7. 5. Vilda pollinatörer i ett svenskt skogsjordbrukssystem

    Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Lisa Conrad; [2018]
    Nyckelord :humlor; bin; pollinering; ekosystemtjänst; biologisk mångfald; alléodling; alley cropping;

    Sammanfattning : Den biologiska mångfalden i världen är akut hotad och är ett av de största problemen inom ekologisk hållbarhet. Inom biologisk mångfald räknas naturligt förekommande pollinerande insekter, vars närvaro minskar. Forskning visar att monotona landskap missgynnar de vilda pollinatörerna. LÄS MER
