Tillväxtreglering av cerealier : tillåtet men inte accepterat av svensk kvarnindustri
Den förste juli 2011 beslutade Kemikalieinspektioen att godkänna användandet av det
tillväxtreglerande preparatet Moddus 250 EC från Syngenta Crop Protecktion A/S i
samtliga stråsädesgrödor. Detta var ett beslut som framkommit efter en dom i
regeringsrätten den 22 september 2010 (KemI, 2011). Samtidigt är inte den svenska
kvarnarindustrin beredd på att ta emot spannmål som är tillväxtreglerad.
Jag blev intresserad hur detta skulle påverka svenska lantbrukare och hur de skulle
hantera denna lagändring som inte går att utnyttja vid odling av spannmål till
humankonsumtion då svenska kvarnindustrin inte tar emot spannmålen. För att
undersöka detta gjordes en litteraturstudie i ämnet samt kompletterande intervjuer med
öppna frågor till fem företag/organisationer.
Litteraturstudien visade på att frågan länge varit aktuell och debatterats sedan 1987 då
den första restriktionen om stråförkortning kom. Denna gällde alla sädesslag utom råg
som var undantaget p.g.a.
Evaluation of an ectomycorrhizal macrofungi as an indicator species of high conservation value pine-heath forests in northern Sweden
Since the 1950s, the development of modern rotation forestry in boreal Fennoscandia has resulted in a severe reduction of older forests, and a high degree of fragmentation among the small patches that remains of old forest. In Sweden, when performing conservation value assessments in order to identify and preserve the remaining forest habitats, the government authorities use to a significant extent a set of indicator species that indicate habitats of high biological conservation value. One species considered to indicate high conservation values in pine-heath forests is the red-listed ectomycorrhizal (EM) macrofungi Sarcodon scabrosus (Fr.) P. Karst. In the present study, the validity of using S.
Trädgårdsergonomi : om konsten att undvika de vanligaste riskfaktorerna för hälsan i små trädgårdsföretag med krukodling
This paper is based on a literature review and interviews made with managers in small-scale nurseries for pot plant production. The review helped to identify the worst occupational hazards in pot plant production. The interviews provided a way to investigate how the nurseries act so as to avoid the worst hazards and what they do to even out work intensive periods during the season in order to get a more even distribution of work over the year.
According to available statistics problems with back and shoulders are the most common of the physical disorders and the risk for occupational accidents are high for greenhouse workers. Most of the occupational injuries are connected to musculoskeletal problems. The handling of material is often manual and involves frequent lifting and carrying of heavy loads, the strenuous work postures and static muscular tensions these repetitive tasks are associated with causes straining and overloading.
Supply & value chain analysis of onions in Ethiopia
Ethiopia is a developing country situated on Africa?s horn. Ethiopia ranks 173rd on United Nations human development index where the least developed country ranks 186. About 85%
of all Ethiopians are employed in agriculture. Onion is one of the basic ingredients in the Ethiopian cuisine and thus an important crop.

Syftet är att minimera ledtider för att kunna reducera genomloppstiden samt hålla låga lagernivåer. Små lager och kort genomloppstid ger en lägre kapitalbindning. På Emhart Glass Sweden AB i Sundsvall där examensarbete har utförts sker montage från minsta detalj till färdig glasformningsmaskin.
Ingen skola är en ö : en studie av förutsättningarna för projekt med närproducerad skolmat på Sollerö skola
Sedan nästan tjugo år arbetar pedagoger och kökspersonal på Sollerö skola med projekt som syftar till att öka miljömedvetenhet hos eleverna och servera dem närproducerad och näringsrik skolmat. Detta arbete består bland annat av odlingar där skolpersonal, elever och föräldrar tillsammans odlar potatis, lök, morötter och rotsaker till skolmåltiderna. Många av de engagerade i verksamheten uttrycker dock att de upplever motstånd från skolledning och kommuntjänstemän, vilket leder till frustration och osäkerhet kring verksamhetens framtida överlevnad. I denna uppsats undersöker jag hur de engagerade i verksamheten påverkas av Mora kommuns policy för verksamheten, hur viktigt skolledningens stöd är för verksamhetens fortlevnad, samt vilka strategier de engagerade använder sig av för att påverka sina förutsättningar. För att försöka förstå detta har jag vid två tillfällen besökt Sollerön och de platser som är aktuella för verksamheten, intervjuat sju personer som är eller har varit aktiva i Sollerö skolodlingar samt deltagit i ett verksam-hetsmöte.
Profitability and competitiveness of grain handling at farm level
The Swedish agricultural sector is currently experiencing substantial structural changes, where the number of agricultural enterprises continuously decreases and the average farm size increases. In order to maintain competitiveness, it is important to be aware and adapt to changes concerning the surroundings of the company (Johnson et al., 2011). Agricultural commodity prices sharply fluctuate on the global market in recent years, affecting the profitability of farmers. High volatility market requires tools to reduce price variations and increases the need of decision-making (Bouder & Beth, 2003). Farm-based grain handling facilities increases the sale options regarding agricultural commodities; a flexible strategy to get additional compensation for the storing the grain produced on the farm (Edling, 2002; Edwards, 2013).
Skötsel av älgskadade bestånd :
Sweden has today the highest moose (Alces alces) population in the world. The population has been very high since the late seventies and in the beginning of the eighties there was a big ?moose explosion?. The main food source for moose during the winter is young pine (Pinus sylvestris) and birch (Betula spp.). The high moose population has therefore lead to high damage on pine forests over big areas.
Inverkan av årstid för förstagallring på avverkningsskador i contorta och tall :
SCA har idag cirka 280 000 hektar beskogad med contortatall (Pinus contorta Dougl. ex Loud. var. latifolia Engelm). Stora delar av den arealen har kommit in i, eller är på väg in i, gallringsbar ålder.
Utveckling av substratmixen vid Mosseruds biogasanläggning : Substratkartläggning och rötningsförsök i laboratorieskala
The world?s growing need for energy together with a desire to ward off the worst consequences of global climate change has resulted in a never seen desire to invest resources in renewable energy sources. Biogas production through anaerobic digestion is one of those growing energy sources. In Sweden there are over two hundred plants that uses this biological process to break down organic substances while producing carbon dioxide and the energy-rich gas methane.This master?s thesis has focused on development of the mixture of different organic substances that is treated at a specific plant, namely Mosserud biogas plant.
Concentration and offtake of trace elements and macronutrients in Italian ryegrass (Lolium multiflorum Lam.) and spring barley (Hordeum vulgare L.) grown on soils amended with water treatment residual sludge
Aluminium sulphate (Al2(SO4)3) is usually added during the drinking water treatment processin order to precipitate organic and inorganic material, resulting in aluminium-based drinkingwater treatment residual sludge (WTR). Since 2003 Swedish law no longer permits WTR tobe deposited in lakes, and there is an interest to explore the possibility to utilize WTR as soilamendment. The aim of this study was to examine the effects of WTR application on cropgrowth and concentrations of macronutrients and trace elements (including micronutrients andpotential toxic elements). A greenhouse pot experiment was conducted with three soils; a clayloam rich in phosphorous (P), a loamy sand rich in P, and a silty loam with a low soil Pconcentration, and two crop species Italian ryegrass (Lolium multiflorum Lam. cv.
Vallbrott med hjälp av grisar :
To investigate the possibilities for effective soil tillage, that could imply lower costs,
lower negative environmental impact and in addition a meaningful occupation for foraging pigs, a field experiment was carried out in Gränna, Småland, during growing season 2006.
The experiment contained two treatments that were repeated three times and were carried
out on a couch grass-infected fallow on a light soil close to Sweden?s second largest lake, Vättern. Ploughing was one treatment and pig rooting followed by ploughing, was the
other. The experiment was conducted according to the guidelines of organic growing and
seedbed preparation was done the same way in the two treatments. The pigs, three groups
of five half-year old Linderödssvin (an old Swedish breed), was encouraged to perform
an even tillage by strip-grazing, i.e.
Aktiviteten hos thymidinkinas 1 i serum från hundar med juvertumörer och malignt lymfom
With the farming methods of the past century the agricultural landscape has changed. This has led to the fact that many habitats and species have been significantly reduced. Sweden is committed to the preservation of biodiversity through various conventions and laws. In the EU's Common Agricultural Policy there are currently agro-environmental schemes, which were created as an instrument for reducing the negative impacts of agriculture on nature and environment. Within this system any farmer who perform environmental measures are financially compensated for this.
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.
