Detta är ett 10 poängs arbete på C-nivå inom ämnet teknologi. Arbetet är skrivet inom institutionen för landskaps- och trädgårdsteknik på Sveriges lantbruksuniversitet i Alnarp. Syftet med arbetet är att undersöka vilka skador som kan uppkomma på betongdammar när vatten och betong står i kontakt med varandra. Målet med arbetet är att uppmärksamma betong som material vid anläggning av trädgårdsdammar. Arbetet inleds med en litteraturstudie där betong som material beskrivs, dess uppbyggnad och sammansättning av vatten, cement, ballast och tillsatsmedel. Därefter beskrivs de för betong vanligaste skadorna vilka är frostskador, armeringskorrosion (rostsprängning), kemiska angrepp och sulfat angrepp. Därefter genomförs tre intervjuer med personer som projekterar och sköter betongdammar i offentlig miljö för att undersöka deras erfarenhet av betongdammar.

The purpose of this report is to examine the possibilities to decrease the number of insects and other pathogens in a crop of pak choi (Brassica rapa), grown with different types of cover and living mulches. Included in the report is a study of literature where amongst others, a summary on the vegetable pak choi and theories of living mulches and different kind of covers are to be found. To examine the amount of predators in the field, traps were used. During the autumn 2002 the tests were conducted in Alnarp. The pak choi and the living mulches were planted/sawn at the same time, the different covers were also applied at this time. The total experiment was divided into six different treatments (plus control) of which three were with covers and three were with living mulches. Once a week the number of leaves, the height and damages were read on ten of the plants from each parcel.

In times of increased flooding, enhanced by climate change, polluted stormwater poses an increased threat to the environment through contaminated water entering waterways. Bioretention utilizes natural processes in soil and vegetation to treat pollutants and combat this threat. Biochar produced through pyrolysis, has a high cation exchange capacity (CEC) and could therefore increase treatment in bioretention systems. This research applies a literature review, interview, and a model to explore the benefits and disadvantages of biochar in order to specify a soil-mix through an understanding of the production process and preferred application rate. High purification through CEC, increased water holding capacity, and carbon sequestration being the benefits discussed.

Background: There is no guarantee that products should be equitable produced. Many products in today's trade is produced by minors, resulting in poor working environment, and gives the workers low payment. Fairtrade is the only label on the market that ensures that farmers receive fair payment for their products. Aim: The central aim with our work is to see what the future consumers, in other words students from Lund's university, Malmö College and The Swedish University of Agricultural Sciences in Alnarp, think about products labeled with Fairtrade, and what they consider is value creation for food products. Students are often relatively young; they educate themselves and have new thoughts and valuations about how the world should be.

In today?s hectic society more and more people experience stress and our lifestyle gives us a very limited chance to recover. For some it sometimes goes that far that they get burnt-out, they have pushed themselves to the ultimate limit. There are different methods and treatments to recover but one very efficient treatment is to spend time in a rehabilitation garden. There the patients get treated by therapeutics that uses the garden as the main tool.The fact that gardens and parks have a positive effect on humans have been used by people for a long time but it?s not until recently that the research has taken speed.

Denna rapport är ett kandidatarbete skrivet inom ramen för Landskapsingenjörsprogrammet vid Sveriges Lantbruksuniversitet (SLU) i Alnarp. Uppsatsen är skriven på C-nivå, och motsvarar 15 hög-skolepoäng, på ämnet Landskapsplanering. Denna rapport tar upp och behandlar det annalkande hotet av de två asiatiska långhorningarna, Anoplophora glabripennis och Anoplophora chinensis, som riskerar att etableras på våra breddgra-der. Där syftet med detta arbete är att studera hur artdiversiteten tar ut sin rätt ifall de asiatiska långhornigarna skulle ge sig på de arter som finns i våra städer. Vad som kan och även kommer hän-da ifall de två etablerar sig på våra urbana träd, samt vilka träd som klarar sig och vilka som har en ökad risk att drabbas av skadedjur kommer att besvaras i denna rapport. Detta för att ge en bättre förståelse för de problem som väntar i framtiden, och för att undvika en ny epidemi som utplånar stora delar av våra urbana träd likt "almsjukan". Rapporten bygger på material insamlat från över 30 vetenskapliga artiklar och databaser.

Title: Nelson Garden AB ? Analysis and recommendations based upon the Service Management System Course: Business Leadership within horticulture and agriculture. Author: Annika Kirilov Tutor: Carl-Johan Asplund Examiner: Anders Kristoffersson, lecturer within business economics, LTJ- faculty, SLU Alnarp Keywords: Bröderna Nelson, Nelson Garden, Service Management System, marketing, customer service, retailer Aim: Explore how Nelson Garden AB manages to reach out to customers through positioning of their own labels, when they as a manufacturer are partly dependent on the competence and sales skill of retailers. Methodology: E-mails were sent out to 6 different companies with a proposition for participation. Of those companies that gave a positive answer the most suited company for the diploma work was selected. Thereafter, a contact was established through telephone with the CEO of the chosen company and relevant questions to him were formulated. The second time of contact the first interview was held and half of the questions were answered.

Vid Jordberga i Trelleborgs kommun i Skåne har SBI Jordberga Biogasanläggning startats under 2014. Skånska Biobränslebolaget (SB3) har tillsammans med bönder i området tagit på sig att odla substrat till denna anläggning, ca 100 000 ton per år. Sedan lång tid har lantbrukarna i området erfarenhet av sockerbetsodling, en gröda som odlas med 50 cm radavstånd. Traditionellt har majs odlats med ett radavstånd på 75 cm i Sverige. Majsodlingen på Söderslätt har varit mycket liten och därför uppstod frågan om biogasmajs kan odlas på 50 cm radavstånd istället för 75 cm. Detta arbete undersöker hur biomassaskörden påverkas av ett minskat radavstånd i biogasmajs.

The study investigates the use of collection and treatment wagon for piglets in relation to castration. The importance of good and ergonomically designed tools in pig stables can probably reduce the risk of suffering from musculoskeletal disorders (MSD). During the last 20 years the number of pig farms has decreased and at the same time the herd sizes and the number of pig keepers have increased (Statistic Sweden (SCB) 2007). As a consequence, the pig keepers have more pigs to take care of, treat and neuter and spend more of their daily work in these large confinements. This also means that the repetitive work e.g.

The Swedish Animal Welfare Act say that all milking cows must have access to pasture in summer time. That was a gift to Astrid Lindgren o her 80th birthday from the Swedish Government. Sweden is a predecessor in animal welfare, but how well do we live up to these big expectations? In this thesis I will examine how well the pasture for milking cows works. I have been interviewing farmers with milking cows and people in the business. I have also been searching information on Internet, and using the library of Alnarp. Cows that are kept on pasture are exposed to different kind of parasites, but on the other hand they run a smaller risk to getting acetonemi, pareses and udder infection. Veterinary Pierre Nordmark means that cows on pasture are more healthy then cows kept inside all summer.

Vad är kvalité i vår utemiljö? I många fall anses landskapets huvudsakliga kvaliteter ligga i dess visuella intryck. Men våra bestående minnen av ett landskap handlar sällan om enbart visuella kvaliteter, utan betydligt oftare om känslor och upplevelser som kan vara svåra att beskriva. Hur beskriver man till exempel känslan av att springa barfota i gräset, doften av skog, eller hur vinden griper tag i kroppen? Idén till denna uppsats uppkom när jag, efter flera års studier på landskapsarkitektpro-grammet, fortfarande ansåg mig vara relativt okunnig i de meningsskapande kvaliteter som landskapet erbjuder människan genom andra sinnen än synen.

The project was initiated by Medipharm which produce microbial inoculants which used as additives to preserve forage. The main goal was to test three inoculants to produce maize silege. The following Medipharm produced inoculants were tested, Milab 393, Lactisil Wolecrop II, Lactisil 300 2. An untreated control was included in the study. The trial was done at Swedish university of Agriculture and Science in Alnarp, Sweden. Eurostar was the cultivar of the maize and was grown on 20, 5 hectares.

Sedan införandet av bredverkande insekticider har frukträdsspinnkvalster, Panonychus ulmi orsakat skada på äppelodlingar i stora delar av den tempererade världen. Kemiska acaricider utvecklades först som en lösning, men deras höga toxicitet och kvalstrens förmåga att bilda resistens har gjort dem omoderna. En lösning på problemet är sprutning med oljeemulsioner, som främst har en fysikalisk verkan. Oljorna tillverkas av antingen mineraloljor eller vegetabilisk oljor och används traditionellt till bekämpning av övervintrande ägg på våren. För att bekämpningen ska vara effektiv krävs dock att den utförs när äggen är som känsligast. Äggen hos P. ulmi blir känsligare ju närmare kläckning de befinner sig.

Under år 2007 observerades dålig etablering och svag tillväxt hos blålupin i ett odlingssystemsförsök i Bollerup, Skåne. Förfrukten var hampa. I led med sockerbetor som förfrukt var blålupinetableringen god och visade inga tecken på försämrad uppkomst eller tillväxt. Samma iakttagelse gjordes år 2008. En misstanke väcktes då om att baljväxters etablering och tillväxt blir tillbakasatt av att odlas I en växtföljd med industrihampa på grund av dess allelopatiska ämnen.

Powdery mildew is a serious problem in both field and greenhouse cucumber production and can cause serious infection and radically reduced yields. Today, powdery mildew is the main disease in greenhouse produced cucumber. Disease control should preferably be both efficient and environmentally friendly, which is not easy to achieve at all times. Alternatives to chemical control of powdery mildews are biological control, physical control, non-fungicide control and cultivation of resistant or tolerant varieties. Biological control can be described as the suppression of damaging activities inflicted of a harmful organism by one or more other organisms, which are called antagonists or natural enemies. In Sweden, there are currently no registered biological control products available to control cucumber powdery mildew. The aim of this study was to investigate the effect of two biological control products in order to evaluate their ability to prevent or reduce powdery mildew infection to an acceptable level in greenhouse produced cucumber. In the experiments, different application regimes were also studied.
