| El estudio de la relación existente entre la diversidad vegetal y la entomofauna constituye un elemento importante para el diseño de agroecosistemas sustentables. Los ambientes semi-naturales en campos cultivados, pueden proveer condiciones adecuadas para la presencia de enemigos naturales, favoreciendo la regulación de plagas y disminuyendo el uso de insumos químicos. Con este fin, se determinaron las características de la vegetación y su relación con la artropodofauna, epífita (trampas de red) y epígea (trampas pitfall), en 13 ambientes semi-naturales en 3 fincas hortícolas de La Plata. Se determinaron riqueza específica; de familias; de géneros; número de especies pertenecientes a las familias Apiaceae, Fabaceae y Asteraceae y su presencia en cada... |

| Der er stor vækst i efterspørgslen efter højværdi kyllingeprodukter, der kombinerer dyrevelfærd, smag og bæredygtighed. Indløsning af dette markedspotentiale kræver udvikling af fødevarekæder der er designet til at producere, håndtere og formidle sådanne højværdikyllinger. MobiChick projektet vil udvikle, teste en dansk højværdikæde for produktion forarbejdning og afsætning af højværdikyllinger, med henblik på opskalering. Projektet inddrager aktører fra alle led i værdikæden. En sådan højværdikæde vil have en række økonomiske og miljømæssige fordele: Kyllingerne indsamler selv højere andel af proteinfoder; relativ lavere næringsstoftab, forbedret dyrevelfærd; produktionen i mobile enheder er let at integrere med andre produktionssystemer, billig og... |

| Two sheep flocks were managed organically for two years from conversion under different lambing strategies (1 lambing/year vs. 3 lambings every two years). The second system was tested because pf a producer’s interest in high productivity, which is a guarantee of good economic results in conventional production.. Reproduction, feeding, lamb production, carcass quality, health (particularly internal parasitism), economic return of the flock, grass production, and pasture biodiversity were evaluated. The lambs were bred with low therapeutic inputs. No economic advantage of increasing lambing frequency was demonstrated, whereas this strategy complicated management and resulted in higher internal parasitic infection of the lambs, and finally showed lower... |

| Die Gesundheit von Bienenvölkern wird gegenwärtig vor allem durch die Varroa (mit ihren Sekundärwirkungen, Viren) sowie durch die amerikanische und europäische Faulbrut bedroht. Die Praxis benötigt mittelfristig eine einfachere Bekämpfung der Varroamilben und eine sicherere und kostengünstigere Diagnostik und Bekämpfung der amerikanischen und europäischen Faulbrut. Praxistaugliche Diagnosemethoden müssen auch für Vireninfektionen bereitgestellt werden, um Antworten auf grundlegende epidemiologische Fragen zu erarbeiten. Die Beurteilung der Qualität und die Typisierung von Honig ist bezüglich der botanischen Herkunft manchmal nicht mit ausreichender Sicherheit möglich. Deshalb sollen die Beurteilungsmethoden und die Kriterien für die Typisierung der... |

| Daisy is a well-tested deterministic, dynamic soil-plant-atmosphere model, capable of simulating water balance, nitrogen balance and losses, development in soil organic matter and crop growth and production in crop rotations under alternate management strategies. Originally it was developed as a system of single models describing each process involved, but recently it has been developed into a framework, which can be used for implementation of several different models of each of the different processes. Thus, for example a number of different models for simulating soil water dynamics can be chosen depending on the purpose of the simulation and the availability of data for parameterisation. The sub-model simulating soil organic matter is still a fixed... |

| La eliminación de vegetación ribereña y un uso intenso de terrazas en el Valle del Río Paraíba do Sul, Estado de São Paulo, Brasil, han causado la degradación de la tierra y la lixiviación de nutrientes y sedimentos por la lluvia. En el año 2008, se introdujo el guanandi – Calophyllum braziliense (3x2m); árbol nativo resistente a inundaciones y productor de madera fina; después del corte de eucaliptos en las terrazas. En 2011 ha comenzado a conversión de agroforestería con un experimento en bloques al azar con 8 repeticiones de cada tratamiento: guanandi, guanandi + yuca (Manihot esculenta) y yuca en sistema agroforestal + guanandi (SAF). La yuca fue plantado entre las líneas de guanandi en filas dobles (0,8 x 0,8 m) y yucas en SAFs fue introducida: Musa... |

| From 26 to 28 May 2004 an international seminar was held in Wageningen, the Netherlands, about current knowledge and advice on rodent management on organic pig and poultry farms in Western Europe. This paper summarizes the discussions. Rodent management is necessary to protect the food production chain from health hazards to livestock and humans.Some organic farmers prefer biological rodent control, but since rodents can also transmit diseases this bears certain risks for the production of healthy livestock and safe food. Effective rodent management requires a thorough understanding of the biology of the pest species concerned. These can be divided into two groups: field rodents, such as voles, and commensal rodents like house mice and rats. The objective... |

| O objetivo deste trabalho foi avaliar a produção e qualidade da beterraba (Beta vulgaris L.) em função de diferentes dosagens de esterco bovino. O experimento foi conduzido na horta do Departamento de Ciências Vegetais da Universidade Federal Rural do Semi-Árido (UFERSA), Mossoró – RN. O delineamento experimental utilizado foi o de blocos casualizados com quatro repetições e cinco tratamentos, sendo estes: 0; 20; 40; 60 e 80 t ha-1 de esterco bovino. As variáveis analisadas foram: produção total das raízes, produção comercial das raízes, massa média das raízes comerciais, altura da parte aérea, teor de sólidos solúveis, teor de ácido ascórbico, acidez titulável, pH e firmeza da raiz. Verificou-se que as doses de esterco não tiveram influência para teor de... |

| Os regimes agrários peculiares e os baixos níveis relativos dos indicadores sócio-econômicos fizeram com que a região do alto Jequitinhonha, nordeste de Minas Gerais, fosse considerada uma das mais complexas do Brasil. Por isso, vários governos orientaram para lá programas de desenvolvimento rural. Mas esses esforços não produziram bons resultados. Este artigo analisa as relações entre programas públicos e agricultura familiar, fazendo um balanço dos métodos e resultados das últimas três décadas. Conclui pela necessidade de incorporar as especificidades de história, ambientes e sociedade aos programas, que deveriam partir das experiências das organizações da região e se ajustar às ações e à cultura desses agricultores. |

| Stimuliert durch ein stetig wachsendes Konsumenteninteresse und finanzielle Anreize des Bundes, hat die biologische Landwirtschaft in der Schweiz in den zurückliegenden Jahren erheblich an Bedeutung gewonnen. Innerhalb der biologisch bewirtschafteten Fläche nimmt das direkt oder indirekt von Wiederkäuern genutzte Grünland den grössten Teil ein. Massgeblich bedingt durch die bedeutende Zunahme der biologischen Milchviehhaltung ist die Kontaktfläche zwischen der tierärztlichen Praxis und dem Biolandbau bereits stark gewachsen. Der Bio-Status eines Betriebes berührt die tierärztliche Praxis vor allen in den Bereichen Komplementärtherapie/Arzneimittelverabreichung und bei den sogenannten zootechnischen Massnahmen (Enthornen, Kupieren etc.). Eine wichtige... |

| Certified organic agriculture stipulates a range of principles and standards, which govern farmer practices. The recent global expansion of organic agriculture has raised new challenges for organic agriculture, particularly whether management practices in organic farms are subject to the forces of conventionalisation. We studied changes in agroecological practices in certified organic farms in China, Brazil and Egypt. The study takes departure in the conventionalisation hypothesis and the analysis is framed using organic and agroecological principles. The study focuses on agroecological design principles, inherent to organic agriculture, of diversity in crop production, pest, disease and weed management, and soil fertility management. The research design... |

| Co-existence is defined as the farmers being able to choose between conventional, organic and genetically modified (GM) crop production, in compliance with the relevant legislation on labelling rules and purity standards. Genes of cultivated plants spread in time and space through pollen and seed dispersal, and in addition handling during transport and processing may also disperse seeds. Consequently, suitable measures during cultivation, harvest, transport, storage, and processing are necessary to ensure co-existence. |
