Försök med olika såmaskiner vid konventionell sådd och direktsådd
In this thesis, two studies with different drills were included. In one of the studies two drills were compared: Väderstad Rapid and Väderstad Spirit. In the other study various drills for direct drilling were compared.
The study with Rapid and Spirit was placed in two locations with different autumn tillage; one on ploughed land in Uppsala and one on cultivated land in Västerås, both with relatively high clay content. Rapid drills have a single disc coulter, while the Spirit drills have a double disc coulter. Various aspects were compared such as aggregate distribution, seed placement, emergence, crop yield and economic outcome.
Vindfällning, tillväxt och plantuppslag i en 13-årig granskärm i Medelpad :
The interest for alternative forest regeneration methods increased significantly during the 1990´s after 50 years dominance of the clear-cutting system (Holgén & Hånell 2000). One reason for this was that clear-cutting was being more and more questioned by different envi-ronmental organizations and because the forest sector for economical reasons wanted to find cheaper ways to regenerate forests. In the beginning of the 1990´s two shelterwood experi-ments were established in a joint effort by Svenska Cellulosa Aktiebolaget (SCA) and the Dept of Silviculture, Swedish University of Agricultural Sciences (SLU). The experiments include various forms of cutting and shelterwood densities and represent productive spruce forests in central and north Sweden (Roggsjön in the province of Medelpad and Skikkis-jöberg in the province of Västerbotten, respectively ). The experiment next to Roggsjön has been reported earlier in three MSc theses, and is also the focus of this thesis.
Tre dimensioner av rörelse : om koreografins bidrag till stadsplaneringen
What causes people to move within and between certain places and not within and between others? How do physical outdoor environments affect the way people act and move? Do different environments generate different body language and mimics in the bodies that inhabit them? In my pursuit for answers to these questions I studied literature and initiated and took part in dialogues in the form of workshops, all of which has resulted into this thesis.
My questions have initially arisen from reflections of my own environment and how it not only affects my mental condition, but also my actions. Drawing upon the hermeneutic term ?preconception? I trust that what we label ?truth? is constructed by our lived experience and the society we grow up in.

Hur påverkas beteende/känslor och fysiologiska faktorer på människa och häst vid interaktion mellan parterna? :
The aim of these two studies was to investigate the possible physiological, behavioural and emotional changes that appear after human-horse interactions and also to find an explanation to why they occur. One aspect that is discussed is whether the wellbeing of humans can be coupled to interacting with horses and of how the animals respond to the interaction. The first study was performed on 9 horses and their owners, both parts being subjects to registrations during 4 different interaction treatments. The second study was performed on 6 horses with registrations only being performed on the horses during 2 different treatments.
Nine horses underwent 3 different treatments all performed by their owners (H = stroking of the horses forehead, B = brushing and M = stimulation of the withers) in addition to a control round (K). Each treatment lasted for 4 minutes but observations were performed until after 45 minutes from start.
Förändrad markanvändning vid biodrivmedelsproduktion : en empirisk undersökning av svenskproducerade biodrivmedels påverkan på åkermarkens användning
Increasing the use of biofuels is an important part of achieving the EU?s target of 10 percent
renewable energy in the transport sector. However, the competition between biofuels and food
production is an ongoing concern. Also, several studies have indicated a significantly higher
climate impact than was earlier estimated, due to emissions from land use.
In Sweden, both the use and production of biofuels from crops have increased substantially
during the last decade. The purpose of this project is first to present an overview of the Swedish
land use in all sectors.
Gäddfisketuristerna : En kartering och marknadssegmentering av de Europeiska marknaderna för gäddfiskande turister i Sverige
This investigation indicates that there are regions within Europe that seems to have similar preferences and priorities regarding pike angling travels to Sweden. Swedish pike angling facilities process in first hand markets with favourable economic circumstances and a cultural interest for pike angling. There was a big differences in features between the Northern, Western, Eastern and Southern regions of Europe. They also seems to be tied to specific regions within some of the nations.The regions have diverse requirements and distinguish in terms of consumption and preferences regarding different aspects of pike angling. From there it is possible to divide pike angling tourists into segments.
Karaktärisering av äpplesorter : för framställning av juice och cider
The purpose of this study was to evaluate which apple cultivars are best suited for production of juice and cider. The study was limited to 41 cultivars. Common as well as uncommon apple cultivars were selected from available cultivars in the cold storage at Balsgård, Department of Horticultural Plant Breeding and Biotechnology, SLU.The practical part of the study consisted of the apples being pressed, and then the juice characteristics being assessed by appropriate criteria and methods of analysis. The analyses consisted of measurment of soluble sugars with a refractometer (Brix), titration of total acidity, determination of total phenolic content with a spectrophotometer, estimation of alcohol content by density meters and qualitative taste tests.The study did not account for different maturity of cultivars. Different apple cultivars were pressed on separate occasions, before and after Christmas 2010.

Röjningsbenägenheten bland privata skogsägare : en enkätundersökning bland medlemmar i SÖDRA
The intensity of cleaning declined dramatically in the early 1990?s in the Swedish forests.
Recession, an economic depressed forestry and the new law of silviculture from 1993, where
the duty of cleaning was removed have been considered as sources to the decline. This has led to a situation where huge areas of forests are untouched, which can lead to negative effects for those stands in the future.
The purpose of this thesis was to find out how the individual landowner acts and feel when it concerns cleaning activities. Has the landowner noticed Södra?s campaigns about cleaning and what sort of measure should Södra implement to increase the members? cleaning activity?
The thesis is based on a opinion poll made through a random draw among all Södra?s members.
Framtida turisttrender och landsbygdsturism : en omvärldsanalys av Frölunda-Aspvik Säteris företagsidé
Frölunda-Aspvik Säteri, a company just outside Stockholm within the agriculture and forestry sector, has developed a business idea around countryside tourism as a complement to their existing business. The idea is to offer a high quality and functional way of living in small cottages surrounded by beautiful nature and landscape of cultural importance. There will also be a range of additional activities available such as hunting, canoeing, cycling etc. The project should be done with minimum impact on the surrounding environment and the importance of the ecological system should be at the forefront of all business decisions. At present the company wants to have a better understanding of what the future trends are within tourism, how its business idea fits in with future trends within tourism and how to stay competitive.The purpose of this research paper is to identify the social driving forces that have an impact on people?s lifestyle and choice of holiday destination in the future, and present how these factors affect the travel industry.
Ägarkategorins och andra faktorers inverkan på skogsfastigheters pris vid försäljning
Sverige består av ungefär 23 miljoner hektar av produktiv skogsmark. Detta innebär att drygt 50 % av landarealen utgörs av skogsmark. Den produktiva skogsmarken är uppdelad mellan olika ägarkategorier, där fysisk person (enskilda ägare) äger 50 % och juridisk person, såsom staten, aktiebolag, ekonomiska föreningar och dylikt, äger övriga 50 % av skogsmarken. Denna fördelning av skogsmarken mellan olika ägarkategorier tros inverka på den skogliga fastighetsmarknaden och en prisdifferens beroende på om fastigheten säljs av juridisk eller fysisk person antas existera. Anledningen till differensen tros bero på bland annat lagstiftning, skötsel och ekonomiska aspekter såsom utbud och efterfrågan på marknaden.
Studiens huvudsyfte var att analysera hur faktorn ägarkategori, där säljaren av skogsfastigheterna delades upp i juridisk person och fysisk person, påverkade skogsfastigheternas köpeskilling.
Clover (Trifolium spp) gamefields : forage production, utilization by ungulates and browsing on adjacent forest
Wildlife is a valuable and renewable resource that promotes economical, ecological and social values. These values are important for developing and maintaining many rural societies. However, growing ungulate populations have led to increased browsing pressure on valuable forest trees and crops. Previous studies have proposed supplementary feeding and gamefields as potential methods for controlling the ungulate foraging and reducing browsing damage by providing other attractive food resources. However, quantitative estimates of potential biomass production of various gamefield crops and browsing pressure on the surrounding forest have been lacking.
Svenska skogsinvesteringar i Baltikum : Omfattning, investeringsmotiv och skogliga skillnader mellanländerna
Uppsatsen beskriver omfattningen av svenska skogsinvesteringar i Estland, Lettlandoch Litauen. Studien kartlägger även de största aktörerna, investeringsmotiv ochsignifikanta skillnader i skogliga förutsättningar i de olika länderna.Eftersom vi inte har funnit tidigare studier av svenska skogsinvesteringar i något avdessa länder, har studien baserats på officiell statistik och faktauppgifter,litteraturstudier, intervjuer, e-postkommunikation, samt information frånwebbplatser. Vi har även genomfört intervjuer i form av en enkät med utvaldaskogsägare.Resultat och analys innehåller en beskrivning av de skogliga parametrarna förrespektive land, en sammanställning av enkätsvar, samt uppgifter omskogsmarkspriser i Baltikum.Baserat på vår uppskattning omfattar de svenska skogsinvesteringarna i Baltikum ca300 000 ha, varav 150 - 200 000 ha i Lettland, ca 100 000 ha i Estland och ca 30 000ha i Litauen. Detta motsvarar ca 4 % av skogsarealen i Baltikum.Bland skogsbolagen är de största aktörerna Bergvik Skog, Södra Skogsägarna,Tornator och Skogssällskapet som totalt äger 115 000 ha. Bland investeringsfondernaär SPP & Storebrand och Europeiska Skogsfonden störst och blandprivatpersoner/företag är t.ex.
Umebors åsikter rörande grönområden
Grönområden kan bidra med en mängd nyttor till en stad som till exempel att reglera lokalklimatet, säkerställa vattenresurser och så vidare. Grönområden gynnar också människors hälsa både genom att verka mentalt återhämtande och underlätta och inspirera till fysisk aktivitet.
Analysen av vad åsikterna kring grönområden i Umeå stad var utgick ifrån en enkätundersökning på nätet som dels publicerades på Umeå kommuns hemsida och dessutom skickades ut med e-post till de föreningar som fanns registrerade hos kommunen samt de verksamma på SLU i Umeå. Datainsamlingen avbröts när antalet svarande uppgått till 1000 stycken. Svaren kom från ett brett urval av befolkningen, och personer med olika åldrar, kön, uppväxtmiljöer med mera fanns representerade.
