| This work studied the anaerobic digestion of brown juice, a liquid residual stream generated from biomass fractionation in a green biorefinery. Biomethane potential batch tests and inhibition studies of brown juice were performed during continuous processing in an upflow anaerobic sludge blanket reactor. Prolongation of the lag phase in the batch tests with increasing substrate/inoculum ratio suggested initial inhibition, which was, however, overcome by adaptation. This was indicated by high final methane yields, which were close to the theoretical maximum of up to 500 L-CH4 kg-VS−1, achieved after 15 days for most of the set-ups. Reactor operation at the organic loading rate of 13.9 g-COD L−1 day−1 and hydraulic retention time of 3 days revealed methane... |

| ABSTRACT: Organic livestock production has increased dramatically in recent years in Europe and other parts of the world. The aim of producing livestock under more natural conditions has led to a reversion to primarily outdoor production systems and less intensive housing when indoor, more forage-based diets, and a reduced reliance on external inputs like antiparasiticides. These major changes in livestock production systems may potentially result in re-emergence (or emergence) of parasitic infections. The basic objective of this paper is to give an overview of the available information on parasitic problems in organic livestock production with a focus on northern temperate regions. Furthermore, options for control that target these problems and are... |

| Four dietary factors (ad libitum versus feed restriction, control versus protein restriction at ad libitum feeding, control versus inclusion of lupine as a protein source at ad libitum feeding, and control versus extra vitamin E at ad libitum feeding) were tested in four separate experiments for the effect on diarrhoea. To introduce a diarrhoea-like condition, half of the piglets were challenged with an inoculation of an E. coli O 149 dose of 1 x 108 colony forming units on day two and three after weaning (day of weaning = day one). All piglets were susceptible since the dams were tested mono-zygotic susceptible to the attachment site of E. coli O 149 in the intestines. Each of the four experiments included 32 piglets from 4 sows. The design was 2 x 2... |

| Legume-cereal intercropping is well known in traditional dry land agriculture. Here, we tested whether finger millet, a shallow-rooted cereal, can profit from neighboring pigeon pea, a deep-rooted legume, in the presence of “biofertilization” with arbuscular mycorrhizal fungi (AMF) and plant growth-promoting rhizobacteria (PGPR), under drought conditions. We conducted a greenhouse experiment using compartmented microcosms. Pigeon pea was grown in a deep compartment with access to a moist substrate layer at the bottom, whereas finger millet was grown in a neighboring shallow compartment, separated by 25-µm nylon mesh, without access to the moist substrate layer. In the presence of a common mycorrhizal network (CMN), with or without PGPR, a drought condition... |

| The aim of this study is to illustrate the importance of farm scale heterogeneity on nitrogen (N) losses in agricultural landscapes. Results are exemplified with a chain of N models calculating farm-N balances and distributing the N-surplus to N-losses (volatilisation, denitrification, leaching) and soil-N accumulation/release in a Danish landscape. Possible non-linearities in upscaling are assessed by comparing average model results based on (i) individual farm level calculations and (ii) averaged inputs at landscape level. Effects of the non-linearities that appear when scaling up from farm to landscape are demonstrated. Especially in relation to ammonia losses the non-linearity between livestock density and N-loss is significant (p > 0.999), with... |

| Soil moisture has high spatial and temporal variability, depending on topography, soil texture, vegetation and meteorological conditions. It influences many processes in the soil and supplies water to the vegetation. This is often a limiting factor in agricultural production. Over an 18-month period, we measured soil moisture dynamics down to a depth of 70 cm in a long-term trial in Bolivia comprising six different land-use systems, i.e. cocoa monocultures and agroforestry systems, both under organic and conventional management, successional cocoa agroforestry systems and a natural fallow. Soil was heterogeneous over the area and in depth. We identified and separated two soil groups which differed in both, texture and soil water retention capacity.... |

| The efficiency of a novel strain of lactic acid bacteria inoculant (Lactobacillus plantarum VTT E-78076, E76) on the fermentation quality of wilted silage was studied. Furthermore, the possibility to improve aerobic stability of silages by combining an inoculant and chemical preservatives was investigated. Two experiments were conducted with wilted timothy-meadow fescue herbage (dry matter 429 and 344 g kg-1) using six treatments. In experiment I, E76 (106 cfu g-1 fresh matter (FM)) was applied alone and in combination with sodium benzoate (0.3 g kg-1 grass FM) or low rate of formic acid (0.4 l t-1 FM). In experiment II, E76 and a commercial inoculant were applied alone and in combination with sodium benzoate. Untreated silage and formic acid (4 l t-1 FM)... |

| Purpose – With the introduction of the mandatory European Union (EU) organic logo for all organic food products in 2010, the European Commission aimed at fostering the internal organic food market. This needs consumers’ knowledge of the logo. According to earlier research consumers’ knowledge of the EU organic logo is low. Thus, the purpose of this paper is to elicit consumers’ attitudes towards organic certification and labelling and to develop recommendations on how to improve consumers’ knowledge of the EU organic logo. Design/methodology/approach – By means of an online survey with 3,000 participants in six European countries, knowledge of the logo and attitudes towards organic farming and European labelling, as well as organic food purchase... |

| From its inception the Soil Association was linked with emerging organic thinking in Australia and New Zealand. When the Association was formed in 1946 two of its founder members were residents of Australia and New Zealand, there were already three like minded associations in the region, and the first issue of ‘Mother Earth’ included three articles from antipodean sources. Given this influence it is perhaps no surprise that in the late fifties the Association’s founder, Eve Balfour, spent a year visiting Australia and New Zealand – arriving an ambassador of the Soil Association, and leaving an ambassador for Australia. |

| In an attempt to evaluate the occurrence and economic importance of plant-parasitic nematodes in organic farming in Germany, a survey was conducted with the main emphasis on vegetable and cereal production systems. For vegetables, the survey included quantification and identification of plant-parasitic nematodes in soil samples and a questionnaire for growers querying production factors and damage levels. For cereals, the survey focused on quantification and identification of plant-parasitic nematodes in soil and plant samples. Overall, Pratylenchus and Tylenchorhynchus were the most prominent nematode genera under both production systems with an incidence of over 90% of the samples. Meloidogyne was detected in 51% of the samples in both systems. Other... |

| Ein zentrales Problem im ökologischen Pflanzenbau ist es, die Schwierigkeiten bei der Regulierung der Unkrautflora in den Griff zu bekommen. Neben den direkten Verfahren der Unkrautregulierung (biologische, thermische oder mechanische Maßnahmen), kommen im ökologischen Landbau vor allem indirekten Maßnahmen eine besondere Bedeutung zu. Neben der Fruchtfolge sind weitere indirekte Unkrautregulierungsmaßnahmen, wie Lichtentzug, Saatgutreinigung, Saatgutqualität, Bodenbearbeitung, Standraum der Kulturpflanzen und Sorteneigenschaften zu nennen. |

| O presente artigo apresenta uma análise do papel da agricultura nos sistemas de produção das Reservas Amanã e Mamirauá, descrevendo sua trajetória recente em nove comunidades, e identificando as principais identidades produtivas. Predomina em todas as comunidades um sistema de produção complexo, formado por agricultura, pesca, caça e extrativismo, com a agricultura ou a pesca assumindo função protagônica, de acordo com a estratégia de geração de renda de cada família. Os sistemas agrícolas vêm passando por intenso processo de transformação, diretamente relacionado à intensificação do contato das comunidades com a vida citadina, com a implantação de políticas de conservação e manejo dos recursos naturais e com o incremento da importância dos produtos... |
