The eutrophication of inshore seas, lakes and watercourses is mainly due to leaching of nitrogen and phosphorus (P) from agriculture. Many efforts are made to reduce the lea-kage of phosphorus in Sweden and the Baltic Sea countries. Phosphorus is also a finite resource and the mining of good quality raw material gets more and more difficult. Se-dimentation dams in combination with filters is one relatively new method to separate P from run-off and drainage water from agricultural land. This study was a part of an IVL Swedish Environmental Research Institute?s project which tests the capacity and func-tion for separation of phosphorus in four phosphorus filters.

Problem discussion: To be competitive in a changeable environment, as the video surveillance market, in a time when the company and the market grow with almost 40% yearly, the sales organization must be well trimmed and effective. Knowledge about customers’ needs and what makes success are essential parts of the progress. Sales Product Management (Sales PM) is a new group at Axis with the main task to support local sales offices around the world in their work with different sales projects. Because of the number of ongoing projects Sales PM needs to be able to screen among these and focus on those where their help will be most valuable for the company. At the same time they have to know which kind of support their sales offices want and need.

Nematodes are perhaps the most common animals in the world. Nematode populations can reach densities up to several millions per square meter in the soil. There are many factors which affect nematode communities in arable soil with respect to diversity and population size. Factors like tillage, crop, Fertilization, nutrient status and moisture in the soil all have an impact on soil biology and in this way also have effects on the nematode community. This study is based on three different parts, soil samples taken in March 2012 and March 2013, soil samples taken monthly during the growth season of 2013 in bare fallow plots and a pot experiment.

Grasslands which have been actively managed for a long time and which in modern times have not been subject to cultivation such as Fertilization are called semi-natural grasslands. These rare and species-rich areas hold an ecological, biological and historical value and if the management stops these areas will likely diminish. More effective agricultural systems and a declining number of grazing animals have in Sweden, among other countries, made semi-natural grasslands less valuable as foraging areas. Shrubs and fast growing plants rapidly colonize abandoned semi-natural grasslands, threatening biodiversity. The objective of this experiment was to determine the effects of breed and season on diet composition, with special reference to four competitive species found in wet areas ? in cattle grazing heterogeneous semi-natural grasslands ? and thereby contribute to improved management of these areas.

För att få en hög produktion i skogen krävs god tillgång på kväve (N). I svenska ekosystem är växttillgängligt kväve den mest begränsande tillväxtfaktorn på fastmark, vilket gör skogsgödsling till den enda skötselåtgärd i Sverige, som rätt utförd kan öka tillväxten i skogen på kort sikt. Enskilda privata skogsägare är den enskilt största gruppen skogsägare i Västerbottens län såväl som i Sverige som helhet. Denna grupp av skogsägare har således stort inflytande över hur den svenska skogen sköts och avkastningen från denna. Syftet med detta examensarbete är att redogöra för enskilda privata skogsägares inställning till gödsling av skogsmark i Västerbottens län. För att kartlägga skogsägarnas ståndpunkt i frågan sattes en enkät ihop som skickades ut till slumpvis valda privata skogsägare i länet. I likhet med tidigare studier visade denna enkätundersökning att de enskilda privata skogsägarna inte gödslar i någon större utsträckning.

Denna studie bygger på en litteraturstudie och ett fältförsök. Vi har undersökt vilken som är den ekonomiskt optimala kvävegödslingen i stärkelsepotatis. Eftersom potatisens kväveupptag varierar mellan sorter, odlingsplatser och år så har vi också undersökt möjligheter att mäta upptaget för att anpassa gödslingen. Syftet med studien var att hitta lämpliga riktvärden för nitrathalten i bladskaft hos stärkelsepotatis vid olika tidpunkter under odlingssäsongen. Dessa riktvärden kan sedan användas som referens vid snabbmätning av potatisens kvävestatus, både för att se kompletteringsgödslingsbehov och för att korrigera gödslingsstrategin över tid.
