| O objetivo desta pesquisa foi avaliar a massa, o teor de proteína bruta da forragem e a taxa de lotação em pastagens de capim elefante em dois sistemas de produção. No sistema convencional, o capim elefante foi plantado em linhas afastadas a cada 1,2m. No sistema agroecológico, o capim foi plantado em linhas afastadas a cada 3m; no espaço entre as linhas, no período hibernal, foram semeados o azevém anual e o trevo vermelho e, no período estival, permitiu-se o desenvolvimento de espécies de crescimento espontâneo. Foram utilizados 150kg de N ha-1 com fertilizantes químico e orgânico para os respectivos sistemas forrageiros. Foram usadas vacas em lactação que receberam complementação à razão de 0,9% do peso vivo. Para determinação do teor de proteína bruta,... |

| Organic agriculture as system approach gains strength if it can produce its own nitrogen, more than what is now realized. This could be done by increased nitrogen fixation on both cattle farms and arable farms, combined with an increased nitrogen use efficiency. Because of these and other reasons, arable farmers can decide to reduce or stop the purchase of manure. Instead of this, cut-and-carry fertilizers could be used. Cut-and-carry fertilizers are alfalfa and grassclover, not sold but used on the farm as fertilizer. This text reports on the design of an arable farm based on the use of alfalfa and grassclover as cut-and-carry fertilizer. This causes a shortage in the P-balance, which is compensated by the purchase of local available compost. The design... |

| Grazed clover/grass pastures are important for animal production systems and the clover component is critical for its contribution to nitrogen (N) inputs via biological fixation of atmospheric N2. The resource efficiency and environmental emissions for clover/grass pastures can differ from that of N-fertilised grass-only pastures. Clover N2 fixation uses photosynthetically-fixed carbon, whereas N fertiliser production consumes fossil fuels and has net greenhouse gas (GHG) emissions. Clover has a higher phosphorus (P) requirement than grass and where extra P fertiliser is used for clover/grass pastures the risk of P loss to waterways is greater than for grass-only pastures. Nitrogen leaching from grazed pasture increases exponentially with increased N... |

| The paper deals with the evaluation of sustainability at farm level in a long term experimental farm organically managed since 1992 in Tuscany. The aim was to develop and implement a multi-objective organic agriculture, to establish new concepts of farming as result of long term research analysis and to provide a practical and easy understanding on what is necessary to change or improve in farming management. Soil fertility and biodiversity indicators are taken into consideration in the period 1992-2006: the weak points and the improvement obtained by the farm management are underlined. The values of indicators changed rapidly towards the desired ones in the first 6 years period. After 13 years, in 2005-2006, the situation appear almost stable, P balance... |

| The research cycle encompass year-long organic vegetable greenhouse production. Spring crop was grown pickling cucumbers followed by autumn tomato. During winter month without heating annual cover crops (mixture of oat, hairy vetch and field peas) were grown and as an green manure incorporated to the soil in spring before cucumber cultivation. Additional organic fertilizers (compost and chicken manure) were applied before cucumber and tomato planting. In the period between cucumber and tomato cultivation the soil in greenhouse was solarizated. In both crops soil surface was mulched with black fleece or fresh red clover biomass. Transplants of both species were produced in organic substrate. Cucumbers were planting in the soil but tomatoes in bottomless... |

| The main objective of the 4-year project was to provide both qualitative and quantitative information on the development of two contrasting organic dairy systems, including the benefits and limitations of each system and also the opportunities for improving the systems. The first system (SS system) was based on an extensive and sustainable system, with the objective of achieving a high level of self sufficiency and sustainability by minimising the importation of nutrients into the system. Therefore, the cropping rotation for the system included forage crops for grazing and conservation and also cereal crops to provide both grain (for feeding as a concentrate) and straw for bedding. The main objective of the second system (PC system) was to change from a... |

| Organic farming systems should be characterized by excellent soil fertility management to keep plant nutrient cycles short and as closed as possible. Therefore, it is extremely important to establish growing systems that have rotations with appropriate crops and intercrops to ensure fertile and biologically active soils, to enhance biodiversity and to provide high quality crop yields. Locally available organic fertilizers include green manures and animal manure. The influence of green manures as intercrops and these combined with composted cattle manure on soil properties, biodiversity indicators and crop yields was studied in a crop rotation experiment in three organic systems at the Estonian University of Life Sciences. |

| Huge amounts of horse manure is either burnt or illegally deposited. Treated correctly it is a good source for plant nutrition and valuable as a soil improvement or for other horticultural uses. To ensure a safe return to agriculture, aspects such as residues of unwanted compounds should be considered. For instance, there is not much knowledge about the fate of pharmaceutical residues in horse manure. An analysing method was developed and found capable of analysing several active ingredients at the same time. When composting horse manure with residues of medicine, three of the tested active ingredients were still detectable in the compost after 60 days. |

| Rapid growth and high fecundity of E. eugeniae makes it a commercial vermicomposting agent. The worm is also a rich protein source (50-70%CP) in livestock diets. The major question, however, is how do we promote earthworm production as a strategy for ecological livestock intensification and integration with crops through earthworm domestication as a source of protein and vermicompost. Reproduction characteristics, growth and offtake of E. eugeniae were studied using four organic substrates including abattoir waste (AW), cattle manure (CM), soya bean crop residue (SBCR) and a mixture of cattle manure and soya bean crop residue (CM+SBCR) aged for 15 days. Irrespective of the substrate, length and biomass of earthworms increased at a decreasing rate between... |

| In Feldversuchen mit verschiedenen Zwischenfrüchten (Phacelia, Grünroggen, Sandhafer, Winterrübsen, Ölrettich, Inkarnat- und Perserklee) wurde das Potenzial zur Reduzierung der Nitratauswaschung über Winter für alle nicht-legumen Arten bestätigt. Aufgrund vglw. hoher Verluste an Stickstoff aus der Sprossmasse über Winter sowie einem weiten C/N-Verhältnis der Zwischenfruchtreste (v.a. Stängel), scheint das Potenzial zur Steigerung der Nährstoffmineralisation im Frühjahr relativ gering sein. |

| Vegetables with a high nitrogen demand such as cauliflower may cause intensive leaching of nitrate to the environment in conventional as well as in organic production. In organic cropping systems, the use of an in-season living mulch may decrease the risk of nitrate leaching after harvest when left growing in the field to the end of the leaching season in spring. The aim of this study was to investigate the effect of growing an in-season living mulch including legumes on the risk of leaching of inorganic nitrogen over winter, and soil nitrogen availability the following spring. Three field experiments were carried out in Slovenia, Germany and Denmark in the frame of the Interveg project (CORE organic II). Evaluation of soil inorganic nitrogen content was... |

| A nine year crop rotation experiment was carried out in the Netherlands from 2002 through 2010 to (1) determine the optimal length of the grass-clover (mixture) and maize period in crop rotations and (2) to determine which crops should receive slurry application with priority in case the availability of cattle slurry is limited. The results show that dry matter yield decreased for all treatments over the experimental period, due to a decrease in plant-available N (from N fixation by the clover, applied slurry and mineralization of soil N). The relative yield increase (increase relative to the negative trend) due to slurry application was largest when all crops received slurry application, and the effects of slurry application increased over time. |

| I denne rapporten presenterer vi seks gårder som viser at det er mulig å forene god økonomi med en miljømessig bærekraftig produksjon, men økonomien var best på de største gårdene. Felles for alle gårdene er næringsrik jord med god jordstruktur og god drenering, fokus på agronomi og godt husdyrstell. Dette resulterte i gode avlinger, god utnytting av tilførte næringsstoff, moderat bruk av energi og moderate utslipp av klimagasser. Fra observasjoner på disse gårdene og diskusjon på arbeidsseminar med gårdbrukerne, prosjektgruppe og inviterte gjester kan vi tipse om noen tiltak for miljøvennlig melkeproduksjon: god drenering, lite kjøring på våt jord, utføre jordarbeiding, gjødsling og høsting straks været og jorda er egnet, slepeslange med stripespreder i... |

| In organic viticulture, canopy features such as leaf area, canopy porosity and fruit exposure are critical due their impact on fungal disease incidence and grape composition. An adequate and accurate assessment of the canopy status is the first step towards appropriate and effective grapevine canopy management, therefore an easy, non-invasive, robust method to evaluate the main features of a grapevine canopy is needed. In this work a protocol for canopy status assessment based on non-invasive RGB imaging is presented and used to ascertain differences in the canopy status of grapevines grown under different degraded and non-degraded soil conditions. RGB images were processed using a classification algorithm based on the Mahalanobis distance, and then the... |
