Sha Jun
The agriculture in Sweden today uses chemical substances to control vermin, weed
and diseases. This usage shows through polluted subsoil water and trace elements in
the food we eat. There?s a risk that additional symptoms will arise in the future.
Our product Sha Jun, developed in 2006-2007, is an attempt to try and minimize the
need of chemicals in the agriculture. The idea started with the attempt to minimize the
usage of pesticides on the cropland.
Tidsstudie - grovfoderhantering :
Since feeding fodder Crops to dairy cows is a heavy and time-consuming but often
disregarded line of work, this study wishes to view the different possibilities that are
currently available to decrease the time to feed and apply this knowledge on an
existing farm. For this purpose, four farms have been studied due to what feeding
systems that are currently used and how long time the feeding required. The occurring
systems are either mobile, i.e. a feed mixer operated by a tractor witch feeds the cattle
via a drivable fodder table, or a stationery mixer, i.e. an electrically powered mixer
which fills an automatic feeder.
Lönsamheten vid nystart av slaktsvinsproduktion : en fallstudie
I have done a case-study about building a new stable for slaughter pigs at a farm close to Kalmar. The farm is able to supply the breeding with cereals and it has enough area to
spread the manure on. The most important factors to gain profit, is the cost for building
the stable, the price of the feeding-stuff and the growth of the pigs. The discount from
the slaughter-house was less important than I thought from the beginning, and it?s a
factor that is hard to influence.
With the new production of slaughter-pig and cattle that already exist on the farm, the
farm will get a well-functioned rotation of Crops with lye and autumn rape as
interruption-crop.
Klimatförändringar och dess effekter på ogräsfloran i Sverige :
Land management for food production is a fundamental human activity and one of the greatest challenges of the 21st century will be to increase the global food to accommodate a world growing to 10 billion or more people, while undergoing climate change. The increasing temperature and the current and projected increase in concentrations of CO2 lead to concern over possible impacts on agricultural pests. This assay is summarizing the knowledge of weeds in a changing climate in Sweden. Global warming and other climatic changes will affect the growth, phenology, and geographical distribution of weeds. The climate change will also affect the weed composition indirect by causing changes in the agriculture.
Undersöka förbättringspotential med verktyg från Lean produktion
In the year 1783 a fissure eruption from Laki in the southern part of Iceland produced a large amount of volcanic gases during a period of eight months. The volcanic gases and aerosols spread across the northern hem sphere due to ideal weather conditions and had a substantial impact on the environment, human health and also climate effects. This, so called dry fog, caused severe health problems, which led to death casualties, killing animals, Crops and other vegetation. The consequence was a widespread famine which was aggravated by a hard and long winter in 1783/84. Analysis shows that the Icelandic volcanoes are the primary risk to produce dry fog that can affect Sweden.
Jordbruk och mjölkproduktion med kor i Etiopien :
Ethiopia is the country with most livestock per capita on the continent of Africa. There are 34.5 million cattle that are used for drought, meat- and milkproduction and 85% of the population rely on agriculture for their survival in some way. Milk is produced in four main systems, through pastoralism in the lowlands, in mixed crop-livestock systems in the highlands, in and near big cities with only one or two cows, and in intensive farming systems. There are 17 cattle breeds in Ethiopia and some of them are more suitable for milk production than others. Several environmental and economic problems arise from livestock holding in the country, for example overgrazing, low production due to feed shortage, low quality of the avaible feed and non-existing breeding programs.
Möjligheter att förutsäga kvävegödslingsbehov i höstvete med Yara N-tester
The Yara N-Tester is a handheld chlorophyll meter which can be used in several different
Crops as an aid to determine if there is a need of complementary fertilization with nitrogen
(N) or not. If the crop requires more N the N-Tester will recommend an amount in kg per ha.
The possibility to assess the need of N depends on the strong relation that exists between
chlorophyll- and N-concentration in the leaves of plants. In the multiannual trial series
?Nitrogen to winter wheat at different soil conditions? measurements with the N-Tester was
carried out at flag leaf emergence (GS 37). In this work the result of measurements, the NTesters
ability to estimate the need of N in winter wheat, will be presented for the years
2008-2011.
Kvalitet i brödvete :
The quality of bread wheat is a large subject to study. The quality rests on two legs. The first one is the inheritance of specific characters, which can be influenced through plant breeding and type of cultivar. The other one is the environmental influences, such as crop rotation, nutrition, harvest and storage. The latter factors are possibly to affect through cultivation practices, while other factors are not possible to influence on for the grower, such as seasonal changes of weather and the soil content.
Gårdsbaserade system för spannmålshantering i den framtida Lantmännenorganisationen :
The Swedish cooperative Lantmännen Ekonomiska Förening has initiated a project labelled "Operation Blåljus" that includes an extensive program for closing down elevators. The number of elevators will be reduced from 92 to approximately 15 after harvest of 2007. The objective of Blåljus is to increase the price of grain with 10 öre/kg. A project has been initiated at the Lantmännen Grain division where the purpose is to provide the farmers with support in their decisions and practical advice how they can load a 35 ton grain truck on 30 minutes. The result from the project will serve as a support system to the farmer in his ambition to achieve cost efficient systems to load a truck with grain on the farm.
Fijian chocolate ?what would it look like?A study of the Fijian food culture, to find the specific attributes that might form the future Fijian chocolate culture
The cocoa produced in Fiji is exported to industrialized countries for processing of the raw material. The Swedish organization Cocoa Bello is involved in a project to provide the Fijian cocoa farmers with knowledge as well as resources to enable local processing and to attain added value of the cocoa crop. The purpose of this study is to discover a field of application for the Fijian cocoa among the rural population, using an ethnographic design. We spent one week in Namau Settlement, Fiji, where we applied in-depth interviews and participant obser-vations in six families. We found a number of aspects affecting food choices, such as social, economical and cultural beliefs.
Olika metoder och tekniska hjälpmedel för att bestämma bevattningstidpunkt :
This examination work on studies and research in articles is mostly from other countries. The purpose of the examination work have been to find out if there are any means you can work with to find out when its time to start irrigation, how they works and if they are credible. In Sweden there is not many means for decide when it?s time to irrigate and how much water you should appear. Swedish farmers think they have so much experience that they don?t need techniques like this.
Vulkanisk svaveldimma : Risken att det drabbar Sverige

Analysis shows that the Icelandic volcanoes are the primary risk to produce dry fog that can affect Sweden.
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.
Validation of realtime-PCR of Fusarium avenaceum for detection in wheat
Mould is a common contamination in cereals. The growth of mould can stimulate mycotoxins production andsome of which at critical concentrations cause health problems in humans and animals. Fusarium is one of thefungus species that has been found in Crops and can cause major problems for farmers such as reduced harvestand economic losses. A group of Fusarium species, Fusarium avenaceum, Fusarium poae and Fusariumtricinctum express a mycotoxin, enniatin. The limited information available today about enniatin-forming fungiis that they grow out on fields of wheat in colder climates.
Post-harvest losses in fruit supply chains : a case study of mango and avocado in Ethiopia
Food insecurity is a great problem worldwide and Ethiopia is one of the sub-saharan countries that are suffering from poverty and food insecurity and a large part of the population are living in a state of undernourishment. To reduce these problems, a successful horticulture production can be an important factor. Compared to other Crops, fruit production in Ethiopia has not been a large part of the agricultural sector. However, the demand on the domestic market is increasing as well as the production for avocado and mango. To increase food security it is important to focus on ways to decrease post-harvest losses of food products and not only have the productivity of agriculture in focus.
