| The present study investigated the effect of gentle touching applied during the last 5 weeks before slaughter in finishing cattle on behaviour towards humans, stress indicators and beef quality. Three Experiments were carried out. Experiments 1, 2 and 3 employed eight Limousin crossbred bulls, eight Piemontese crossbreds (six females, two steers) and ten Limousin crossbreds (three females, seven steers), respectively. Half of the animals were equally assigned to a treatment and a control group. The treatment group consisted of a standardized gentle head-neck-region touching and started 5 weeks before slaughter and was continued once a week in experiments 1 and 2 and twice a week in experiment 3 during the following 5 weeks. Avoidance distance tests (ADT)... |

| This work aims to evaluate the soil physical properties affected by cover crop rotation and soil management in a long-term experiment in southern Brazil. The experiment was established in 1986, with treatments combining six winter treatments and two tillage systems (conventional and no tillage). Bulk density, porosity, aggregate-size class distribution, and organic carbon content of the aggregates were determined at six depths. Bulk density was not affected by tillage systems and winter treatments. The soil disturbance by plowing enhanced the macroporosity, decreased the microporosity, and promoted the formation of smaller aggregate size, in comparison to no tillage. Apart from the soil management, all winter species increased the greater aggregate–size... |

| China is at the onset of an organic agriculture revolution. From 2000 to 2006, China has moved from 45th to 2nd position in the world in number of hectares under organic management. China now has more land under organic horticulture than any other country. In the year 2005/2006, China added 12% to the world’s organic area. This accounted for 63% of the world’s annual increase in organic land, and China now has 11% of the world’s organically managed land. The antecedents to China’s Organic Revolution are examined, and reveal further growth potential in the Chinese organic sector. Longitudinal analysis of China’s food production statistics reveals explosive growth, and the consequent capacity for export has implications for food exporting nations. China has... |

| For further optimisation of organic agricultural systems, more focus is required on organically produced seeds and the development of better adapted varieties. Organic plant breeding and seed production need to comply with the concept of naturalness as applied in organic agriculture, which not only includes the nonchemical and agro-ecological approaches, but also the integrity of life approach. As organic environments are less controllable and are more variable, breeding should aim at improved yield stability and product quality by being adapted to organic soil fertility as well as sustainable weed, pest and disease management. Also the ability to produce economicacceptable seed yield avoiding seed-borne diseases should be included. On the short... |

| Det er en almindelig antagelse, at tryneringning af udegående søer mindsker udvaskning af nitrat og andre næringsstoffer fra græsmarkerne, og at miljøet dermed skånes. Man kan se, at ringning forhindrer søerne i at rode, hvorved græsdækket holdes intakt på en stor del af marken det meste af året. Men fak-tisk ved vi ikke, om udvaskningen fra en mark med ringede søer er mindre end fra en mark, hvor søer kan rode. Det er vist, at der er væsentlig udvaskning fra områder omkring fodersted, sølehuller og hyt-ter fra marker, hvor søerne har været tryneringet. Det kan tænkes at denne punktforurening er værre for vandmiljøet end en jævn spredning af samme forurening. Fra forsøg med ringede og ikke ringede søer ved vi, at søerne ikke lider ved at have trynering.... |

| Background and Aims A number of root and root hair traits have been proposed as important for acquisition of P. However, it remains unknown whether these traits are most important in determining macro- and micronutrient uptake at low soil fertility. This study investigated the variations in root and root hair traits among spring wheat genotypes and examined which root and root hair traits are most important for high uptake of macro- and micronutrients. Methods Six spring wheat genotypes were grown in a soil with low nutrient availability. The root and root hair traits as well as the content of macro- and micronutrients were identified. Results A significant genetic variability in root and root hair traits was found. High root growth vigour and long and... |

| For the operationalization of the structured, stepwise selection procedure for non-target testing organisms integrated into the new EFSA guidelines for environmental risk assessment of GM plants practicaltools – i.e. ranking matrices – were developed. These tools – some of them are new and some are refinedfrom older ones – were tested using the GM case crop of TC 1507 maize. The selection procedure consists of six steps. The strategy builds on identifying the important ecological functions for the particularcropping system and compiling a species lists according to their ecological functions and presence inthe specific receiving environments. Subsequently, the species numbers are reduced in a systematic,stepwise fashion to a relevant and practical number... |

| O presente trabalho teve como objetivo realizar um diagnóstico da pesca e aqüicultura no município de Conceição da Barra, litoral norte do Espírito Santo, e propor ações de gestão multidisciplinares. Detectou-se que os problemas que levaram à decadência da atividade pesqueira local foram, principalmente, a pesca predatória, a destruição dos ecossistemas e a falta de planejamento, organização e capacitação do setor. A partir disso, foram propostas ações visando à elaboração de projetos que permitam agregar valor aos recursos pesqueiros e incentivar e fomentar a aqüicultura sustentável de base familiar. |

| As the livestock numbers on Finnish dairy farms have increased and most fields on dairy farms are under grass, it has become common to spread cattle slurry over grasslands. To estimate environmental effects of recurrent slurry applications, a 5-year field study was performed to compare nitrogen (N) losses to water and ammonia losses to air by volatilization, when cattle slurry was either surface broadcast or injected into clay soil after grass cuttings. Slurry was spread on the grass in summer (1996–1997) or both in summer and autumn (1998–2000). Biomass N uptake before grass harvesting and amount of soil mineral N in spring and autumn were measured and field N balances were calculated. Despite cool weather, up to one third of the ammonium N of broadcast... |

| Aims Belowground legume nitrogen (N) composed of roots and rhizodeposition is an important N input to soils, but published data of belowground N vary broadly, probably due to extrapolation from short-term experiments and dissimilar growing conditions. We quantified belowground N inputs of red clover (Trifolium pratense L.) during two consecutive years in a clover-grass sward along a soil nutrient availability gradient. Methods We established a red clover-perennial ryegrass (Lolium perenne L.) model sward in microplots located in field plots of the DOK experiment, which has a 33-year history of organic and conventional cropping, resulting in a soil nutrient availability gradient. Four treatments were examined: the zero fertilisation control, bio-organic... |

| Die zukünftigen Rahmenbedingungen lassen eine steigende Ressourcenkonkurrenz zwischen Nahrungs- und Futtermittelproduktion erwarten. Gerade die Rindermast wird in diesem Zusammenhang sehr oft kritisch betrachtet. Das Ziel der vorliegenden Arbeit war es daher, unterschiedlich intensive Rindermastsysteme hinsichtlich ihres Ackerflächenbedarfs und ihres Beitrags zur Netto- Lebensmittelproduktion zu untersuchen. Die Analysen beruhen auf Daten eines Mastversuchs mit Kalbinnen, Ochsen und Stieren der Rasse Fleckvieh auf Grassilage- bzw. Maissilagebasis. Die Tiere der Grassilagegruppen wurden auf drei unterschiedlichen Kraftfutterniveaus (extensiv, niedrig, hoch) und die Maissilagegruppen auf hohem Kraftfutterniveau gemästet. Die... |

| Este estudo apresenta os principais resultados da análise de como habitantes de Alto Paraíso de Goiás estão buscando alternativas para o desenvolvimento sustentável do município, por meio da implantação, pela Embrapa, de projeto relativo ao resgate do café. A mineração e as atividades agropecuárias foram exercidas na região até os anos 60, quando a atividade principal passou a ser o turismo, a partir da criação do Parque Nacional da Chapada dos Veadeiros e da inauguração de Brasília. Em 2000, o fluxo de turistas decaiu devido a problemas relativos à saúde pública, acarretando estagnação da economia local. Nos últimos anos, produtores familiares despertaram para a existência, ali, de um café que pode ser comercializado em nichos de mercado de grãos... |

| Este trabalho resgata o significado do termo desenvolvimento sustentável e salienta as diferentes ideologias implícitas em duas correntes de pensamento, a ecotecnocrática e a ecossocial. A partir da análise destes enfoques de desenvolvimento, observa-se a insustentabilidade da agricultura convencional e destacam-se os princípios da Agroecologia no processo de construção de estilos de agricultura sustentável. Nessa perspectiva, aborda-se a utilização de sistemas agroflorestais como estratégia para a promoção do desenvolvimento rural sustentável. Com base na revisão bibliográfica são analisados três projetos de sistemas agroflorestais na agricultura familiar em distintos biomas brasileiros. Conclui-se que estes projetos possuem características que podem ser... |
