Kaliumgödsling på torvmark - effekt på tillväxten hos planterade granar (Picea abies)
Peat lands are a great potential resource for increased forest growth in Sweden, there are approximately 6.5 million hectares of peat lands, whereof around 70% produce less wood than one m3sk/ha and year and are therefore classed as forest waste land. There are over 200 000 hectares of peat land that is already drained and wooded, and that may be suitable for fertilization. Forest production on peat soils usually requires drainage and fertilization. Dewatering requires ditching the area, so that the roots can have access to oxygen. Nitrogen is often abundant in the peat but other nutrients; especially potassium is in short supply. The purpose of this work was to examine the effects of potassium fertilization on the growth of spruces that were planted on drained peat land and how different amount of fertilizers affects the growth. Potassium deficiency is strongly growth inhibiting, since potassium is important for substance transport in the tree. Potassium is also important for the carbohydrate formation, and because increasing the sugar content of the cells constitutes a lower freezing temperature does potassium availability in the soil play a major role in the winter resistance of many species. Potassium is not found in any organic compounds in the tree, but is present in cell and tissue fluids. A fertilization trial was started in 1978 in Siljansfors Experimental Forest. The plots in the experiment were fertilized with different amounts of potassium and one plot was left without fertilization. All plots that were fertilized with potassium grew considerably better than the unfertilized plot. The difference in production between the unfertilized plot and the plot that received the most potassium was 7.2 m3sk/ha and year. The unfertilized plot can still be classified as waste land. The theoretical production capacity was estimated using a Swedish system for site quality estimation of wetlands after ditching (dikningsbonitering). The plot with most potassium produced after fertilizationaproximately in level with theoretical estimations. Key words: Peat land, Fertilization, Ditching, Growth, site quality..
Utvärdering av näringsstatus inför återskapande av kalkkärr vid Hagebyhöga, Östergötland
Calcareous fens constitute a specific habitat which is uncommon in Europe and protected by the EU habitat directive due to its importance to several threatened species. Hagebyhöga in Östergötland is a calcareous fen habitat included in the Natura 2000 Networking Programme. Adjacent to the existing fen, a degraded fen area is situated. The area has been used for agriculture for several years but is now going to be restored to its former state by the county administrative board of Östergötland.When working with restoration of degraded fen areas it is important to aquire knowledge about the chemical soil conditions. Plant growth limited by phosphorus and low fertility are characteristic conditions for calcareous fens, whilst arable land usually is highly fertile and limited by nitrogen.The purpose of this study is to bring forth useful knowledge for restoring the degraded calcareous fen of Hagebyhöga.
"Danmarks fremtid dit land - dit valg..." - En analys av Dansk Folkepartis bok
I min uppsats har jag valt att undersöka Dansk Folkepartis bok Danmarks fremtid dit land - dit valg. Jag har främst gjort en retorisk analys av materialet utifrån Lennart Hellspongs bok Metoder för brukstextanalys. I kombination med den retoriska analysen har jag även valt att använda Teun van Dijks bok Elite discourse and racism för att få en breddare förståelse av materialet. Med hjälp av van Dijks bok och hans diskussion av olika retoriska strategier och diskurser försöker jag göra det lättare att förstå och se Dansk Folkepartis sätt att påverka. Jag för även en kortare diskussion av bilder och dikter som förekommer i boken..
En värld av ?i? och ?u? : -En studie av u-länder i geografiböcker för gymnasiet
I uppsatsen har två geografiböcker för gymnasiet studerats. Fokus för undersökningen har varit böckernas framställning av "de andra", i det här fallet representerat av periferin, u-länder eller tredje världen, beroende på vilket uttryck som väljs att användas. De två undersökta böckerna, Geo- guiden och Geografi- människan, resurserna, miljön, brukar främst begreppen u-land och i-land för att beskriva världens fattiga respektive rika länder. Även begreppet NIC-land förekommer i böckerna men inte i samma utsträckning. Geografi- människan, resurserna, miljön presenterar även begreppen centrum- periferi, vilka dock inte används i särskilt hög grad.
Miljökonsekvensbeskrivning för en utökning av befintlig djurhållning :
In the last few years the environment becomes more watchful, even for us farmers.
All agricultural enterprises that exceed 200 animal units must be tested according to
regulation of environment. A farm business with 200 animal units and more is classed
?environmentally hazardous activities? and has to make an environmental impact
assessment for the business you have today, and the activity after expansion.
Before you can construct a building and expand the numbers of animals is a lot of
applications to make. I have in this project restricted me to establish a environmental
impact assessment and a consultation foundation.
To make a environmental impact assessment is the big part of the application. The
environmental impact assessment take a lot of time and you need skills for all the rules
in the environmental code to be abele to make an environmental impact assessment
approved.
The environment codes purposes (1 kap 1 § Miljöbalken) is to rule the laws.
The purpose of the environment code is to promote sustainable development which will
assure a healthy and sound environment for present and future generations.
Definitions of a ?environmentally hazardous activities? 9 kap 1§ Miljöbalken) shall
mean the discharges of wastewater, solid matter or gas from land, buildings or structures
onto land or into water areas or ground water.
Markavvattningsföretagens geografi och konsekvenser i Trosaåns avrinningsområde
Agricultural drainage is widely used to manage the amount of water in the ground in order to improve conditions for cultivation. However the effects of drainage companies on water regimes are considerable leading to runoff changes such as altered stream flows, peak flows and water levels. In a greater extent this could imply an increased risk for floods along affected watercourses. This study analyzes the extension of agricultural drainage within the drainage basin of Trosaån in Sweden by ArcGIS mapping. In a statistical analysis, historical variation in streamflow in relation to mean precipitation and mean temperature are investigated for the study area.
Professionell Hästhållning : grundinformation till lantmästare
Every year, the horse industry in Sweden is growing. Because of this growth, it wouldbe most beneficial for the people involved in the agricultural business in Sweden toimprove their horse skills.I have assembled a form that includes basic guidelines for professional horse care.History tells us that Swedish horses have had a huge impact on the agricultural business.Before the arrival of the tractor, the horse played a very important role for the farmer.Today, horses are kept primarily for pleasure, mostly as a hobby for non-professionalpeople. In Sweden, we are seeing the small horse farms become more and morepopular, which is keeping the countryside open and alive.I feel it is very important to improve the knowledge among farmers and others who willwork in close proximity to horses. This will enable us to raise the standard of care ofhorses today and reduce the number of people who market themselves as professionalhorse specialists, even though they have no education or experience in the fieldIn this essay you will find information about the most common horse breeds in Sweden,including basic anatomy of the horse, feeding directions, hoof and dental care, commondiseases and their treatment. There is information relative to the safe transportation of ahorse as well as the rules pertaining to horses in traffic.
Marknaden för skogsvårdstjänster : en undersökning bland privata markägare inom en region i Värmland
This work broadly illuminates the conditions for increasing the commissions of forestry services within the whole, or parts of, the western regions of Stora Enso?s operating area. Through a questionnaire, a survey was made examining whether the owners of the forests themselves do the forestry on their woodlands. This foremost concerns the pre-commercial thinning, but also planting and soil scarification. The survey also shows who are buying the most part of their forestry services and who are carrying it out themselves.
Växelkursens betydelse för utrikeshandel : En jämförelse mellan ett EMU-land och Sverige
Uppsatsens syfte är att analysera den nominella växelkursens påverkan på utrikeshandel och göra en jämförande studie mellan ett EU-land (Sverige) och ett EMU-land (Tyskland). Fokus för denna undersökning kommer att ligga på vad som skedde med utrikeshandeln under de två ekonomiska kriserna på 2000-talet, men även ge en generell bild för utrikeshandeln under hela perioden 2000-2010. Uppsatsen avser att besvara om det finns några skillnader i hur ländernas handel påverkades under kriserna med avseende på växelkursen, samt om handelssammansättningen av handelspartners förändrats. Detta kommer undersökas för att se hur Sveriges utrikeshandel påverkats av att stå utanför EMU.Resultaten visar på att den nominella växelkursen inte haft stor betydelse för utrikeshandeln under den undersökta tidsperioden. Både export och import har ökat under perioden, men det går inte att finna någon direkt koppling till växelkursförändringar.
Jämförelse av de nationella normerna i Eurokod inom Norden
Masonite Beams AB är ett företag som är väl etablerat i Sverige men har för avsikt att expandera till främst Norge, men även till de andra Nordiska länderna. Masonite Beams behöver därför skapa nya spännviddstabeller för sina I-balkar med hänsyn till de olika nationella bestämmelserna i respektive land. Detta examensarbete behandlar de olika nationella kraven för Sverige, Norge, Danmark och Finland för bostadsbjälklag. Arbetet omfattar en dimensionering i respektive land för ett HI300 bjälklag. Samtliga aktuella länder baserar sin dimensionering på Eurokod med nationella bilagor.De olika nationella valen till Eurokod resulterade i stora skillnader i den maximala spännvidden för ett HI300 bjälklag.
Rättsliga krav på vindkraftsetablering på land
Huvudsyftet med denna uppsats är att undersöka rättsläget avseende tillståndsgivning till vindkraftverks etablering på land. I uppsatsen behandlas miljöbalkens första fyra kapitel. I studien granskas det först tre tillståndsärenden från tre olika länsstyrelser och sedan genomförs en kortare rättsfallstudie över prejudicerande domar avseende lokaliseringen. En mycket tung vägledning för lokaliseringsbedömningen utgör, både för länsstyrelserna och för domstolen, översiktsplanering eller andra eventuella planeringar och policy. Länsstyrelserna behandlar planeringar eller policy med en annan utgångspunkt än domstolen gör.
Fosforförluster från lantbruket och dess bidrag till övergödning av sjöar och vattendrag i Växjö kommun
The possibility for plants to utilize phosphorus in soil is a prerequisite for conducting agricultural production, both small scale and professional. Spreading of phosphorus fertilizers and manure is therefore seen as a necessity in today's agriculture in order to achieve high yield. Manure management, livestock farming and manure storage could contribute to the eutrophication of lakes and rivers. For instance, when the ground becomes saturated, phosphorus leakage could be seen in surface runoff or in point sources resulting from inadequate manure storage management.In the municipality of Växjö there is still many bodies of water that do not reach the Swedish environmental water quality standard of "good ecological status". This thesis has therefore analyzed the manure management and storage on agricultural farms which may have contributed to eutrophication in the municipality.The method for this thesis was a literature study, a questionnaire survey with 820 receivers and a summary of issued inspection reports from 2013.The results highlight the ways in which agriculture may have contributed to the eutrophication of lakes and streams in the municipality of Växjö.
Effekter av två olika hösilagefoderstater på tarmfloran och träcksammansättningen hos häst och gris :
The aim of this study was to investigate if the botanical composition of haylage affects pH, dry matter content and microbial composition of the faeces in horse and pig and ileal environment in pigs. Two separate studies were conducted where pigs and horses were fed two diets containing haylages with different botanical composition. The first haylage was from a tilled land dominated by timothy and meadow fescue and the other haylage came from a meadowland with a large inclusion of dandelion, 25 % and common couch. The dry matter content (70.8 % and 73.0 % respectively) and the pH-value (5.7) were similar in both feeds.
The first study was made as a three-periods switch-back study with 7 Standardbred horses. In the first and the third period, 7 and 9 days long respectively, the diet consisted of the haylage from the tilled land, oats, sugar beet pulp, soy bean oil meal, lucerne pellets and brewers yeast.
Ett land - Flera identiteter. En analys av Kinas nationalism i relationen till Hongkong
Den första juli 1997 firades Hongkongs återförening med Kina med pompa och ståt. Den brittiska kolonin blev Hong Kong Special Administrative Region (SAR) inom Kina. Hongkong skulle behålla sitt politiska system sida vid sida med fastlandets under principen "ett land, två system". Vi har identifierat att principen innebär en konflikt i den specifika situationen och använder oss av Browns teori om tre typer av nationalism. Kinas kommunistparti använder två typer av nationalism för att samla invånarna i en nation och legitimera sitt styre.
Förändring av nitratläckage och växtproduktion från låglänt jordbruksmark vid en ny reglering av vattennivån i Mälaren
The water level of Lake Mälaren has been regulated since the 1940?s. A recentinvestigation suggests that the current regulation needs to be adjusted in order toprevent a decline in water level, salt water from infiltrating from Lake Saltsjön,and risk of floodings. In addition to these preventions, the new regulation couldpotentially effect the natural environment and agriculture practices in the lowlands that surround the lake. The new regulation proposal calls for an increase invariations in Mälaren?s water level during seasons, while the annual mean waterlevel will remain the same.
