| 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... |

| Um dos procedimentos da Agricultura Orgânica (AO) é o processo de conversão, pelo qual a atividade agrícola em manejo convencional muda para o manejo orgânico. No caso do café, a conversão do sistema convencional para o orgânico pode trazer consigo, entre outros benefícios, a independência de insumos externos, menor risco para a saúde e pode proporcionar maior lucro ao produtor. Esta pesquisa tem como objetivo verificar a viabilidade econômica da produção orgânica de café no Sítio Terra Verde em Espírito Santo do Pinhal, no estado de São Paulo, para o processo de conversão da técnica convencional para a orgânica. Utilizou-se a metodologia de programação linear para maximizar o lucro e minimizar o custo de produção do café em dois cenários. O plano de... |

| Ninety certified organic pineapple producers were interviewed using a semi-structured questionnaire in Luwero and Kayung districts in Uganda. Data was analysed using statistical package for Social Scientists (SPSS). Results indicated that most organic farmers (81.1%) kept mostly cattle in combination with others species (goats, pigs and chickens). There was no significant difference (P>0.05) in the numbers of pigs, poultry and chickens owned per farm in the two districts but there was significant difference (p=0.017) in the numbers of cattle. 62% of the farmers had indigenous breeds of cattle, 97.8% had goats, 87.5% had pigs and 100% of farmers had indigenous chickens. Crop residues formed bulk of feed for cattle (63.2%) and pigs (46%). Goats mostly... |

| Soil fertility management is a major concern in organic farming. According to the EEC Regulation 2092/91, soil fertility must be maintained and/or increased by legumes cultivation. Native Mediterranean legumes ecotypes are more persistent than commercial varieties but their use in catch crop sequences is still limited. The N2-fixing legumes crops as a local resource can be considered as an alternative to improve nitrogen nutrition and to increase crop yields. This study aimed to investigate the agronomic performance of seven annual self-reseeding legumes and the short–term effect of nitrogen supply on the subsequent crops. Results are presented from field experiment on sandy-clay soil, pH 8.1 and 1.6% of organic matter, in the south of Italy, where the... |

| Parasitism with gastrointestinal (GI) nematodes is ubiquitous in grazing cattle and its control is critical to sustain satisfactory levels of animal health, welfare and productivity. Currently, conventional parasite control strategies relying exclusively on anthelmintic drugs are severely threatened by the development of anthelmintic resistance (AR) in bovine nematodes in several countries. In Denmark, cattle farmers and their veterinarians depend largely on macrocyclic lactones (ML), mainly ivermectin (IVM), for nematode control. However, no studies have evaluated the field efficacy of IVM against GI nematodes in Danish cattle. Alternative control approaches to minimize selection for AR and that can complement the use of the still effective anthelmintics... |

| Increasing drug resistance in gastrointestinal (GI) parasites of livestock and concerns about chemical residues in animal products and the environment are driving the development of alternative control strategies that are less reliant on the use of synthetic drugs. An increasingly investigated approach is the use of bioactive forages with antiparasitic properties as part of the animal’s diet (nutraceuticals) or as potential sources of novel, natural parasiticides. Chicory (Cichorium intybus) is a multi-purpose crop and one of the most promising bioactive forages in temperate regions, and numerous in vivo trials have explored its potential against parasitic nematodes in livestock. However, it is unclear whether chicory can induce a direct and broad activity... |

| O objetivo deste estudo foi verificar a ação do uso do inseticida Imidacloprido + beta-ciflutrina em relação ao número de visitas de abelhas Apis mellifera nas inflorescências do girassol. O trabalho foi conduzido no mês dezembro de 2008 na Estação Experimental da Copagril, no município de Marechal Cândido Rondon, PR. Antes do período de florescimento foram marcadas cinco plantas dos híbridos de girassol M734, Charrua, Aguará e Helio 250, com quatro repetições cada. Dois observadores permaneceram dois minutos em cada inflorescência, contando o número de abelhas visitantes em dois intervalos de tempo (8h30min às 10h e 15h30min às 17h). A contagem ocorreu antes da aplicação do inseticida e 12 horas após a utilização do produto. Verificou-se que houve efeito... |

| In einer norddeutschen Demeter-Gärtnerei wurden 2003 versuchsweise Arbeiten in Gemüsepflege, Grundbodenbearbeitung und Futterbau mit Zugpferden statt Schleppern durchgeführt. Dabei wurden die Kosten der Pferdehaltung und der Geräte erfasst sowie deren Leistungen. Zum Projekt gehörte ein Rechts/Links-Versuch zu Verdichtungen als auch Bearbeitung von Anfragen und Öffentlichkeitsarbeit. Die Pferdearbeit wurde nach dem Projekt im Betrieb fortgesetzt, die Qualität der Arbeit war sehr gut, in den Leistungen war das Pferd insgesamt langsamer als der Schlepper. Auf den Boden wirkt das Pferd sich günstig aus. Unter klaus.strueber@web.de kann der Gesamtbericht angefordert werden. |

| There was a lack of up-to-date statistics on the working time requirements in suckler cattle farming under Swiss production conditions. A combination of final and causal methods for recording working time was used to determine working-time input and working-time requirements, to survey influence variables and draw up working-time models using a model calculation system. The total working time spent on suckler cattle farming varied between 28 and 120 hours per cow per year, with an average of 66 hours per cow per year. Over half of this time was spent on routine work, 20 % on management work, 19 % on other non-daily work and 3 % on direct marketing, animal care and animal handling, respectively. The larger the herd size, the lower the time spent on... |
