Vad påverkas odlarna av i den svenska morotsodlingen? :
In this degree project I write about how the farmers who grows carrots in Sweden get
influenced by different rules, investments and demands. The Swedish agriculture are
heading towards a harder time, and then you have to find new things to do. Now its
hardly no profit to grow grain so you have find other crops. This paper is not a
comparison between the contract cultivation to Findus and the cultivation where the
farmer maked his products by a own company on the farm.
If you have a small processing company on the farm, you have to increase the
standard with different certificate. The farmer binds a lot of capital in machines, both
field and in the process.
En ekonomisk hållbar växtodling i sörmländsk mellanbygd :
We have been looking at three different types of agriculture in Södermanland, in the middle
east of Sweden. We call the different types for Intensive, Extensive and Mix. The purpose is
to get an economic defensible plan for how to run different farm sizes. We also have been
looking at the working hours and how many hours the different types will give.
We have a farm called Taxinge Gods as our pilot farm. Taxinge Gods grow 407 ha land and is
located 60 km southwest from Stockholm.
Kan IT påskynda utvecklingen i Peru?
Med bakgrund av flertalet försök att hjälpa utvecklingsländer mer IT stöd, så syftar rapporten till att pröva hypotesen att IT, både direkt och indirekt, kan påverka utvecklingen positivt i Peru. Direkt genom positivt påverkan av individers möjligheter till information och utbildning etc. Och indirekt genom att möjliggöra för ?catch up? effekten. Rapporten tillämpar en övervägande deduktiv metod för att baserat på tidigare forskning genomföra en kvantitativ underökning, i form av en enkätundersökning lokalt i Peru.
Fosforläckage från växtodling - orsaker och ågärder :
Phosphorus is essential to all plants and is taken up from the soil as the ion H2PO4 - (and to some extent HPO42-). Plant availability depends on, among other factors, the soil pH. In order to provide for plant available phosphorus, it is applied as mineral fertilizers and farmyard manure. However, that causes phosphorus leaching from arable land to surrounding surface waters and lakes and contributes to the eutrofication. There are three types of soils in Sweden that are at higher risk of contributing to phosphorus leakage.
Svenska sojabönor - finns marknadsmöjligheter?
The large-scale soy cultivation has negative consequences for the habitat of local populations because of the intensive use of pesticides and the destruction of rain forests and eco-systems. GM soya, varieties are often used. The majority of Swedish people, however, do not want GM products in their food. It will be hard in future to ensure GM free food, particularly foods that come from countries where GM crops are grown on a large scale. It is very difficult to avoid cross- contamination when both GM and non-GM crops are grown in the same area.
Koldioxidavgång vid ekologisk odling på organogen jord
The background of this work is the media discussion about the effect of cultivation on peatsoils on greenhouse gas emissions. It has been argued that row sown and intensivelycultivated crops such as carrots are more likely to emit carbon dioxide than for example grassleys. The association KRAV (an association promoting organic farming) shall, from this yearadapt their environmental policy to be more climate smart and have asked the question if thecultivation of some crops is more climate smart than others? Carbon dioxide emissions fromsoil are due to degradation of organic material and the rate is controlled by microbial activity.The microbial activity is determined by a variety of factors such as temperature, soil organicmatter quality and water content. I have measured the carbon dioxide emission from fourdifferent crops at two different farms.
Gödslade eller ogödslade mellangrödor som biogassubstrat?
Jordbruket står idag inför utmaningen att öka produktionen av biogas-substrat utan att öka konkurrensen om jordbruksareal för foder- och livsmedelsproduktion. Fånggrödor odlas idag för att reducera jordbrukets kväveläckage till vattendrag. Genom litteraturstudie, intervjuer samt fältförsök undersöktes potentialen för att använda fånggrödor som biogas-substrat (då som mellangrödor), samt huruvida biogaspotentialen förhöjdes genom en mindre kvävegiva i samband med sådden av mellangrödan. Från tidigare publicerad litteratur kunde ses att endast en del utav det upptagna kvävet i fånggrödan återfanns i markprofilen till nästkommande gröda. De två huvudsakliga källorna till kväveförluster var lustgasavgång samt läckage av lättomsättbart kväve över vintern, med varierande nivåer på kväve-förluster beroende på lokal och gröda.
Metodikstudie av trollingfisket i Vänern : Jämförelse av fångstrapportering mellan intervjuer och enkäter gjorda på trollingfiskare samt vädrets påverkan på ansträngning
There are five endemic populations of migratory Atlantic salmon (Salmo salar, Salmonidae) and brown trout (Salmo trutta, Salmonidae) remaining in Lake Vänern, whereof two are salmon and three are trout. There is one population of each species in Klarälven, also one of each in Gullspångsälven and there is a population of trout still remaining in Tidan River. Since the beginning of the 20th century endemic populations of salmon and trout have either vanished or declined dramatically due to the construction of hydropower in the rivers around the lake, and still today the future of the remaining populations remains uncertain. To manage salmonid fishes effectively more knowledge of their ecology throughout their different life-stages is needed. A large part of the Lake Vänern salmonoids lives are spent in the lake, where a mayor mortality factor is recreational fishing, especially angling.
Alternativa stråbränslen i växtföljden :
The purpose of this report is to find out which crops, that are good for strawfuel, and can be grown i the area around the city of Lund. The background of this report it that Lunds energy is planning to bild a biofuelheated thermal power station in Örtofta outside of Lund.
I have in the report limited me to the crops hemp, whole crop (triticale), reed canary
grass, elephant grass and jerusalem artichoke. I have through a documentary research
checked the crops, cultivabillity in the south of Sweden, and how they should fit, in the
Scanian crop sequence.
Hemp is an annual crop which probably could manage in the Scanian crop sequence.
Whole crop often triticale because of it´s high yield and low rate of shed seed. Could
also fit into the crop sequence of crop in Scanian. Triticale is annual, and could be
grown at the same kind of fields as used to wheat, whith is why it would be possible to
grow it in Scania.
Reed canary grass is a reedlike grass that is easy grown at most soils.
Vattenflödets betydelse för fångster av lekvandrande lax (Salmo salar) och öring (Salmo trutta) : En utvärdering av laxfällan vid vattenkraftverket i Forshaga
Many watersheds have lost stocks of migrating fish species because of the development of hydroelectric plants and other fragmenting barriers. The remaining stocks of migrating Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) in River Klarälven, Sweden are five times smaller compared to one hundred years ago. A fish-trap at the hydroelectric plant in Forshaga has been vital for the continued existence of the stocks. This is the first hydroelectric plant of eight, blocking the way to the spawning grounds. Spawners are collected in the trap for both hatchery and transport by truck upstream and past seven more hydroelectric plants to the spawning grounds, where they are released for possible natural reproduction.
Resistenta rapsbaggar :
Oilseed rape crops are an important in southern Sweden because of the high intensity
of wheat growing. Pollen beetles are the most important pest in oilseed rape and
causes often economic losses. Therefore it?s of great importance that we can control
the population density, e g by using insecticides if necessary, to avoid mayor yield
losses.
In year 2000 pollen beetles were numerous in the province of Östergötland. The
farmers sprayed with insecticides several times, but with low effects on the beetles.
Field trials and laboratory experiments showed that pollen beetles had developed
resistance against pyrethroids.
Timeliness cost for agricultural sprayers : weed control in cereal crops
Evaluation of machinery costs is necessary for selecting appropriate farm machinery. Timeliness cost due to untimely operations is an important component of machinery costs. Timeliness costs can be high for crop sprayers, since pesticide application must be carried out within a short time interval. This Master thesis investigated the timeliness cost and the probability of a suitable workday for spraying. Timeliness factors were estimated for four different crops (oats, spring wheat, winter wheat and barley) using historical weed trial data.
Grovfoder för dikor
This literature review examines different forages which are well suited for suckle cow production in Sweden today. They should also be possible to cultivate in Sweden under the current circumstances. Crops suitable for grazing in Swedish climate but not used in Sweden today, but which may be relevant for Swedish conditions are also mentioned. In Sweden today, mainly grass silage, straw and hay are used as forage, but also wholecrop silage is used to some extent. However, concentrates are not used to a greater extent, since it contains too much energy.
Konsten att kränga en kommun : en diskursanalys av en kommuns externa kommunikation
University of VäxjöSchool of Social SciencesBachelor Thesis in Political ScienceTitle: ?Sverigedemokraternas valframgångar 2006 ? En ulv i fårakläder??Author: Emma Haraldsson and Åsa NeuschützTutor: Emil UddhammarThe aim of this study is to explain Sverigedemokraterna?s electoral success in 2006 and the essay assumes that some form of change has occurred. To study this change two hypotheses have been constructed. The first hypothesis concerns the change within Sverigedemokraterna and the second hypothesis concerns the change of the Swedish voters attitudes.Kirchheimers catch-all theory is used to explain the change in Sverigedemokraterna. The catch-all theory states that parties have to change their structure to maximise the number of votes.
Fungiciders påverkan på kvävehalten i höstvete : hur påverkar användandet av fungicider utnyttjandet och inlagringen av kväve i höstvete?
A common perception is that fungicide treatments increases yield, but that the nitrogen of the particular grain is diluted so that the overall removal of grain nitrogen from the field remains unchanged. The aim of this paper is to demonstrate that a healthy crop reduces the risk of nutrient loss from agricultural land. The results from genotype and plant protection trials often show constant nitrogen content in the grain, although the yield has been increased. Results from such experiments are therefore processed in order to confirm this and show that it is no statistically significant difference between the protein content (and also nitrogen content) in crops which have undergone fungicide treatment compared to crops which remained untreated. The trials processed have been carried out in the southernmost part of Sweden and are distinguished to concern winter wheat production.The explanation to the results is that a healthy crop is able to maintain the biological functions of the plant in a more efficient way than a crop damaged by a fungal infection.
