| Gewasresten van het landbouwbedrijf en maaisel uit beheersgebieden vormen reststromen die geschikt zijn als organische meststof. Deze reststromen kunnen als input voor composteren worden gebruikt. Bij composteren verdwijnt een deel van de organisch gebonden koolstof naar de lucht. Een alternatief is het fermenteren en conserveren van maaisel en andere inputs is het zogenaamde Bokashi-methode. Bokashi betekent “goed gefermenteerd organisch materiaal”. Met behulp van micro-organismen, zeeschelpenkalk en kleimineralen wordt het fermentatieproces in werking gezet.Het fermenteren vindt plaats onder zuurstofloze omstandigheden. In Noord-Holland zijn experimenten gedaan met het bereiden van Bokashi en die zijn vergeleken met compost. De waarde van Bokashi kan... |

| Can organic agriculture elaborate a scientifically based, resource-efficien and agroecological approach to low-input farm management? This review examines the literature from temperate regions, with a particular emphasison Canadian and USstudies that relate to environmental and ecological impacts of organic agriculture with respect to (i )soil organic matter storage, (ii) soil quality/soil health, (iii) nutrient loading and risks of off-farm nutrient and agrochemical losses, (iv) biodiversity and (v) energy use and global warming potential. The context and implications of semi-arid conditions and low soil P levels, common to many organic farms in North America, and wide spread adoption of genetically engineered crops in conventional production, is also... |

| Objectives The feasibility study shall answer the following questions: Are there economical and ecological advantages of on-farm dry digestion biogas plants? How the construction and operation parameters of a dry digestion biogas plant influence environment, profit, and sustainability of on-farm biogas production? The aim of the feasibility study is to provide facts and figures for decision makers in Finland to support the development of the economically and environmentally most promising biogas technology on-farm. The results may encourage on-farm biogas plant manufacturers to develop and market dry anaerobic digestion technology as a complementary technology. This technology may be a competitive alternative for farms using a dry manure chain or even... |

| Increasing size of organic dairy farms makes grazing of all cropped land inexpedient due to long distance to the milking facilities. We investigated nutrient dynamics and feed production in two dairy crop rotations with differences in proportion of grazing and cutting. One six year crop rotation represents close to the farm buildings (barley undersown with grass-clover - 4 years of grass-clover - spring barley/catch crop) and another represents further away (barley undersown with grass-clover, 2 years of grass-clover -barley/catch crop - maize/catch crop - lupin/catch crop). In each of the crop rotations was made five treatments concerning grazing/cutting strategy and manure application. Results shows that herbage production was high in year 1-4 of... |

| One core idea behind organic production is that cropping systems should be less dependent on resource import than conventional production and minimize negative environmental effects. This study aimed to test novel organic rotations, designed to reduce reliance on external resource import. We compared a conventional system (C) and an organic system relying on manure import (O1) to two rotations (O2 and O3), both relying on autumn cover crops for soil fertility, and in O3 green manure rows were left as intercrops. Resource import differed between 149, 85, 25 and 25 kg N ha-1 year-1 in C, O1, O2 and O3. Crop yields were lower in the organic systems (on average 82% of conventional yields), differing among crops, when based on the area grown with main crops.... |

| I foråret 2013 blev der gennemført et kombineret fodrings og infektionsforsøg med økologiske hønekyllinger på AU’s forsøgsfaciliteter i Foulum. Formålet med forsøget var at undersøge indflydelsen af fodring med fluelarvemel som alternativ proteinkilde til fiskemel på økologisk fjerkræ. Derudover skulle effekten af fodring med friske levende fluelarver på fuglenes tarmsundhed og adfærd undersøges. En eventuel probiotisk effekt af fluelarverne kunne ikke udelukkes, da fluelarverne var dyrket på frisk fjerkrægødning med henblik på at opnå kompostering. Derudover var formålet med forsøget at undersøge om fodring med friske fluelarver og larvemel påvirker forløbet af en Salmonella Enteritidis infektion hos kyllingerne. |

| I FØJO III projektet ECOVIT undersøges det, i hvilket omfang det er muligt at optimere vitaminindholdet i grovfoderafgrøderne ved at foretage det optimale valg af afgrøder, høsttidspunkt, forvejring og lagerform. I projektet har vi undersøgt forskellige græsmarksafgrøder dyrket i både Danmark og Sverige og sammenholdt resultaterne fra de to lande. Resultaterne viser, at der er betydelige forskelle i vitaminindholdet mellem afgrøder og hen over dyrkningssæsonen. Generelt har bladrige grønne afgrøder det højeste vitaminindhold. Tabet under forvejring og lagring varierer også ganske betydeligt, og det er vanskeligt at give præcise retningslinjer for, hvordan dette tab minimeres mest muligt. Det ser dog ud til, at en lang forvejringsperiode øger tabet, og det... |

| Post-harvest sown catch crops should be sown as early as possible in order to obtain maximum biomass and nutrient uptake in the harvested crop, as biomass production decreased by 2-3.5 percent per day, when time of sowing was postponed throughout August. Furthermore, the winter hardy species included in these experiments had a tendency to yield less than the non-winter hardy catch crops. These experiments imply that early sown catch crops may become a biomass supplement for organic biogas production, provided sufficient yields are obtained and costs for harvest, transportation and storage are adequately low. |

| O presente trabalho teve por objetivo avaliar as propriedades e/ou características físicas, químicas e biológicas, de solos cultivados com algodão por agricultores do município de Tauá - CE, para testar a hipótese de que o sistema de cultivo do algodão em bases orgânicas, proporciona uma melhor qualidade do solo que o cultivo convencional de algodão. Para tanto, foram selecionadas seis áreas de plantio em bases orgânicas e três áreas de plantio convencional, levando-se emconsideração o tipo de solo e a topografia. Em cada uma das áreas escolhidas, foram estabelecidas três subparcelas representativas dos consórcios adotados, com aproximadamente 1 0 0 m2 cada uma, as quais serviram como repetições dentro de cada área. Como indicadores da qualidade do solo,... |

| The use of alternative to mineral fertilizers is an important issue in organic systems. A four-year field experiment to evaluate the effects of organic fertilizers on yield and quality of processing tomato and proteic pea in rotation, was carried out in Southern Italy. The fertilization treatments aimed to supply 100 kg ha-1 of N for tomato and 60 kg ha-1 of P2O5 for pea and were: 1) an organic biological fertilizer (BIO); 2) an experimental compost obtained by olive residues, sludge and straw mixture (COMP); 3) a control managed with traditional chemical fertilizers (ammonium nitrate and perphosphate, MIN). At harvest, the main productive and qualitative parameters were assessed. Tomato fruit yield did not differ among the fertilization treatments, but... |

| In organic cropping management of Medicinal and Aromatic Plants, the best quality expression is crucial to gain satisfactory incomes. Coriander (Coriandrum sativum L.) is an annual herbaceous plant with a commercial value due to the typical scent of its fruits (commonly termed “seeds”), rich in a pale yellow oil (1-2% in small-sized types, 0.2-0.5% in large-sized ones). Several studies have been done for determining the composition of volatile fraction of Coriander, which was found to vary also as a consequence of cropping techniques, including nitrogen fertilization. In order to gain useful information about the effects, if present at all, of organic N fertilization on Coriander quality in terms of volatiles composition pattern, a three-year trial... |
