| As a result of continuous growth in the organic market, organic food is increasingly available in conventional retail outlets, where organic products are placed alongside both conventional and so called conventional-plus products. Conventional-plus products are food products with particular attributes that also apply to organic products, such as ‘no artificial additives or flavours’. This overlap provokes the question whether conventional-plus products might compete with organic products. The aim of our study was to identify occasional organic consumers’ preferences and underlying determinants in relation to organic, conventional and conventional-plus milk, fruit yoghurt and apples in Germany and Switzerland. To achieve these objectives, we conducted... |

| The objective of the present study was to compare the colour, chemical composition, meat quality and fatty acid profile of the longissimus dorsi (LD) muscle of growing bulls housed in an insulated tie-stall, an uninsulated barn or a forest paddock. Two housing experiments were conducted at the North Ostrobothnia Research Station of MTT Agrifood Research Finland in Ruukki (64°44’N, 25°15’E). The first experiment was conducted from November 1999 to October 2000 and comprised 30 Hereford bulls, the second from November 2000 to December 2001 with 30 Ayrshire bulls. In both experiments the bulls were divided into six groups of five animals according to live weight and the groups were randomly allotted to one of three treatments: tie-stall in an insulated barn... |

| Tomato plants were grown in open beds, confined beds, or combined beds with compost based on clover grass hay, deep litter and peat. Plants grown in the confined and the combined beds produced the earliest tomatoes. During the first five weeks of harvest, approximately 18% of the fruits produced in confined beds developed blossom end rot. This disorder was hardly developed in the other growing systems. After five weeks of harvest, these differences in fruit production were unchanged or even increased. Plants grown in the confined beds produced significantly less fruit load compared with the other bed types, especially in 2003. Application of supplemental fertilizer did not significantly increase the fruit production in any year. |

| Growth processes are often problematic for small-scale farms as they may disturb their delicate balance of basic internal resources, like labor, buildings, machinery, land and animals. Most of these resources cannot be increased in linear processes and the smaller the unit the more problematic the task of realignment of resources becomes. Thus small-scale farmers often feel growth as enforced upon them by outside factors, e.g. a market partners. Growing enterprises in processing and trading need more supply and obviously are not eager to deal with more small suppliers, as this tends to mean higher transaction costs and varying qualities. However, there are examples where dedicated supply chain actors actively engage in preserving small scale structures and... |

| A good working environment is part of the fundamental values in organic farming. In Denmark the association of organic farmers state, that the aim of organic farming is "to give everyone involved in the organic production a high quality of living". But how do the organic farmers actually experience their own working situation? And what factors play a part in their daily physical as well as psychological working environment? These were the questions we set out to answer in a project at the Danish Institute of Agricultural Science. |

| The below- and aboveground communities of fungal entomopathogens (Ascomycota: Hypocreales) were investigated in an experimental conventional and organic vegetable cropping system over two seasons in Denmark. The experimental design allowed for evaluating differences between farming practices in the occurrence of soil-borne fungal entomopathogens and as natural infections aboveground in arthropod hosts. Belowground, Metarhizium anisopliae dominated the agricultural field with Beauveria bassiana, Metarhizium flavoviride and Isaria fumosorosea being present at lower frequencies. Abundances of M. anisopliae were not different between conventional and organic soils. Aboveground, B. bassiana was the most common fungal entomopathogen in arthropod host cadavers.... |

| As a fast growing state sponsored industry, the organic food sector is likely to attract the increased attention of policy analysts who are interested in industry development. We critically review the European comparative research on growth in the organic sector, focusing on policy analysis. A common element in these accounts is that findings are by no means clear on why variation in organic growth between countries exists. The literature provides a range of possible variables explaining divergent patterns of organic sector development but solid conclusions are elusive. We suggest that future policy orientated research on organic sector apply existing theories on public policy and carefully design studies in accordance with the prescriptions of the... |

| Um den Einfluss von Kompost und Gärgut auf die Bodenfruchtbarkeit und auf das Pflanzenwachstum abschätzen zu können wurden hundert, für die Schweiz repräsentative, Proben untersucht. Die Gehalte an Nährstoffen und an Salz waren vom Ausgangsmaterialien abhängig. Die Gehalte an organischer Substanz sowie die Atmungs- und Enzymaktivitäten nahmen mit zunehmender Kompostreife ab. Bei einigen jungen Komposten konnten Stickstoffblockaden beobachtet werden. Der Nitratgehalt im Kompost erlaubt jedoch vorherzusagen, ob eine N-Immobilisierungsgefahr besteht oder nicht. Die Phytotoxizität der Komposte variierte auch bei den reiferen Produkten sehr stark. Dies weist auf die grosse Bedeutung der Rotteführung und der korrekten Lagerung der Produkte hin. Während die... |

| Eficiência climática (EC) é um índice que demonstra em termos quantitativos a redução produtiva ocasionada pelo déficit hídrico. Assim, este trabalho teve como objetivo avaliar a EC das culturas da soja e do trigo para o estado do Rio Grande do Sul, considerando-se diferentes locais e datas de semeaduras. A EC foi obtida pela relação entre as produtividades atingível (PA) e potencial (PPf), estimadas por meio de modelos de simulação. A PA foi obtida pela estimativa da PPf, a qual foi determinada pelo método de Zona Agroecológica da FAO, deflacionada pelo déficit hídrico em cada uma das fases das culturas para cada data de semeadura, entre os anos de 1979 e 2008. Os resultados evidenciaram que as datas de semeadura influenciam a EC para a cultura da soja, a... |

| Hemp seed yields of the variety Fedora-19 in an on-farm scientific field experiment on small plots and in an on-farm evaluation in 11 hemp fields under practical organic growing conditions in Lower Austria were compared to give a realistic view of the variability of yields. Dry matter seed yields from the on-farm field experiment ranged from 127 to 143 g/m2. Under practical growing conditions, yields ranged from 34 to 151 g/m2 in the sample plots. The reported hemp seed yield after combine harvesting, drying, and cleaning was between 324 kg/ha and 717 kg/ha. The results of the experiment show that harvesting by hand considerably influences yields. Yields of the manual harvest in sample plots indicate a high correlation with yields harvested by the combine... |

| There are new trends in agriculture to move toward the low input systems with the lower application of chemical fertilizers. To reach this goal, different methods, such as the application of biofertilizers, may be used. So this experiment was conducted in 2010 at a research farm in Arak, Iran, in factorial in the form of a randomized complete block design with three replications and four factors: animal manure (M), Pseudomonas putida (P), Azotobacter chroococcum (A)and Azospirillum lipoferum (Z). Results indicated that manure significantly affected grain yield (P≤0.01); the highest grain yield was achieved in the interaction of manure × Azotobacter × Pseudomonas (4.556 ton/ha). Grain yield was not significantly affected by the microorganisms. Moreover, the... |

| Our aim was to compare udder health in groups of organically and conventionally managed cows, using data from a longitudinal study in a Swedish dairy-research farm. Management of the groups was identical except for feed composition and the feeding regimen. Our dataset included all lactating cows calving from 1 September 1990 to 31 August 2001 (145 organically and 151 conventionally managed cows). Udder health was assessed by the geometric average somatic-cell count (SCC) within 150 days after calving, by the number of monthly SCC tests >200,000 cells/ml within 150 days after calving and by presence of lactations with veterinary-treated cases of clinical mastitis. The effect of animal group was analysed by multivariable linear, Poisson and... |

| Nitrogen (N) is often the most limiting nutrient in organic cropping systems. N2 fixing crops present an important option to improve N supply and to maintain soil fertility. In a field experiment, we investigated whether the lower N fertilization level and higher soil microbial activity in organic than conventional systems affected symbiotic N2 fixation by soybean (Glycine max, var. Maple Arrow) growing in 2004 in plots that were since 1978 under the following systems: bio-dynamic (DYN); bio-organic (ORG); conventional with organic and mineral fertilizers (CON); CON with exclusively mineral fertilizers (MIN); non-fertilized control (NON). We estimated the percentage of legume N derived from the atmosphere (%Ndfa) by the natural abundance (NA) method. For... |

| The present study evaluated the effects of feeding strategies with alternative feeds on the performance of mature suckler cows and their progeny during indoor feeding and subsequent grazing. In both experiments, a 2 × 2 factorially arranged design consisted of two feeding strategies (Step-up, S; Flat-rate, F) and two diets (Control, C; Alternative, A). The aim of Strategy F was to offer the cows the same amount of energy as offered on Strategy S, but at a constant daily level. In Experiment 1, cows on Diet C were offered grass silage and straw and on Diet A grass silage and a fl our-mill industry by-product. On Strategy S, feeding was stepped with barley (0, 1.5 and 3.5 kg d-1). On Strategy F, barley was offered 1.43 kg per head daily. In Experiment 2,... |

| Quantitative real-time PCR (qPCR) is slowly becoming established as a tool to quantify abundance of different arbuscular mycorrhizal fungal (AMF) taxa in roots and in soil. Here, we describe the development and field validation of qPCR markers (i.e. primers with associated hydrolysis probes), targeting taxon-specific motifs in the nuclear large ribosomal subunit RNA genes. Design of such markers is complicated by the multinuclear and multigenomic cellular organization of these fungi and the high DNA sequence diversity within the smallest biologically relevant units (i.e. single-spore isolates). These limitations are further compounded by inefficient biomass production of these fungi, resulting in limited availability of pure genomic DNA (gDNA) of... |

| Global food trade embodies a range of different interpretations of the nature of food and its role in society. On the one hand, the WTO food regulation regime, in particular the SPS agreement, is based upon a somewhat instrumental value of food consumption in which food is seen as a commodity to be traded in accordance with international trade rules. At the same time, a number of private standards, such as GlobalG.A.P and various organic standards, are emerging which embody broadly postmaterialist values that suggest that food purchasing and consumption are also social, ethical and perhaps even political activities. This paper analyses the relationship between the WTO food trade regime on the one hand and the GlobalG.A.P and organic food trade regimes... |

| The weed flora in conventionally and organically grown spring cereals was investigated in southern and central Finland during 2007–2009. The survey was conducted in 16 regions, 283 farms and 595 fields (72 organically cropped and 523 conventionally cropped fields, of which 503 were treated with herbicides). The occurrence of weeds was assessed in late July–early August. Altogether 148 weed species were identified, of which 128 were broad-leaved and 20 grass species. In organically cropped fields, the average species number per field was 21 and the most frequent species were Chenopodium album 96%, Stellaria media 94%, Viola arvensis 94% and Elymus repens 89%. In conventionally cropped fields, the average species number was 12 and the most frequent weed... |
