| The concept of „unpackaged shopping“ aims at reducing waste along the entire value chain. Our project focusses on analysing the value chain of unpackaged food with regard to potentials, barriers and opportunities to expand the concept. The first results revealed that there are several challenges for “unpackaged shopping” to be observed, which can be grouped under six perspectives: supply, marketing, “inside”, “outside”, environment, and branch. For instance, the producers and suppliers are hesitant to change packaging processes due to a lack of demand, wholesalers are faced with potential additional cost for deposit systems, stores are having difficulties finding appropriate products and customers are struggling with the additional efforts of... |

| Community supported agriculture (CSA) is increasingly practised in different countries all over the world and can be seen as a step towards a new style of urban-rural relationship. However, it is argued that CSA is an “utopian entertainment for a few middle class consumers and their fortunate few farmer friends” (Goodman and DuPuis 2002, p. 17). Often, such CSA projects rest on organic agriculture, a farming system which in turn provides food mainly to the middle class of well-educated concerned consumers (Morgan and Murdoch 2000). Thus, one could argue that organic CSA is a highly exclusive concept, and that, in consequence, building urban-rural relationships depends on a small part of society ignoring, for example, poorer, often less educated consumers.... |

| In order to assess the risk of the use of recycled phosphorus (P) fertilisers for organic farming, the potential accumulation of heavy metals in soil after a 200-year fertilizer application equivalent to 11 kg P ha-1 yr-1 was calculated in a mass balance approach. Both fertilizers currently allowed in organic farming and recycled P fertilizers were regarded. For heavy metals, four scenarios with two soil pH levels (pH 5 and pH 7) and two precipitation excess levels (F 0.1 and F 0.3 m yr-1) were calculated. Recycled P fertilizers like struvite, meat- and bone meal, ashes, sewage sludge and digestate, as well as phosphate rock and triple superphosphate had a higher P content and a lower heavy metal-to-P ratio than composts. Consequently, compost application... |

| The legislative rules of keeping ruminants on organic farms do not differentiate between the requirements of the different species for the housing systems. Thus, the types of locomotion typical for goats (e. g. climbing, jumping) have not to take in consideration in stables designed for goat keeping. Some farmers offer their animals elevated resting platforms (niches), but data concerning the preferences of the goats and the labour management of such areas are not available. A herd of non-lactating goats (breed: Bunte Deutsche Edelziege) was parted in six experimental groups with ten animals in each group. Over a period of seven days the animals were kept separated in a part of the stable furnished with resting niches. Twelve niches were arranged on three... |

| White lupin (Lupinus albus) can be an interesting crop for both organic and conventional farmers who are looking for leguminous crops to broaden their crop rotation scheme. Lupin is also of interest for food processors as a guaranteed GMO-free protein source for the replacement of soy. However, the available varieties ripen too late in the Netherlands. Furthermore, the largest areas suitable for arable farming are calcareous rich clayey soils. So, there is a need for early maturing calcium tolerant varieties. The goal of this study was a broad evaluation of lines of white lupin for suitability for cultivation on clayey soils high in calcium content, in order to determine whether there is sufficient perspective for further breeder for both conventional and... |

| The aim was to determine the differences in mineral composition and sensory properties of cloudy apple juice depending on apple cultivation system. Three indigenous Estonian cultivars were chosen on condition that the same cultivars would be grown in organic and conventional orchards at the same geographical location. ’Krameri tuviõun’ and ’Talvenauding’ apples were harvested from old (over 30 years) low maintenance orchard and ‘Krista’ apples from 10-years old experimental orchard. 100 kg of apples per cultivar and cultivation system were stored at +3±2°C for two months and then pressed into juice using Lancman waterpress. Total soluble solids (TSS), titratable acidity (TA) and content of P, K, Ca and Mg were determined from apples and from juice.... |

| Buffer zones were effective in decreasing losses of eroded soil particles, total P and particulate P in surface runoff from fields ploughed in autumn. The retention of DRP was low, the DRP loads to surface runoff might increase on BZs in winter and early spring. The grass should be cut and the swathe removed on the BZs. Innovatons, with them DRP can be retained on BZs especially in winter and spring >StoP. On pasture and in direct drilling, the mean annual DRP load was slightly smaller on the VBZ with native scrubs and herbs compared with NBZ (p=0.05, p=0.07, respectively). There was a significant treatment x season interaction on surface runoff, TP, and DRP and almost significant on total solids (erosion), and PP. |

| Plant based organic fertilisers were tested in plot trials on their effect as N supply for vegetable crops. Radishes (Raphanus sativus L.) and white cabbage (Brassica d-eracea var. capitata L.) were chosen as fest crops. Beside the unamended control four ({R}adish trial) and two ({C}abbage trial) fertilisers were investigated: Castor pomace (Ricinus communis L), pellets of crushed seeds of lupin (Lupinus luteus L), and faba bean (Vicia faba var. minor L.) and Phytoperls® (Zea mays L). They were applied in two N-levels {(R): 80 and 140 kg N ha-1; (C): 120 and 240 kg N ha1 with the two first mentioned fertilisers}. Castor pomace and lupin seed pellets were found to be more efficient N supplies than faba bean seed pellets and Phytoperls®; on the Iow level... |

| Abstract – Seed-borne diseases are increasingly becoming important in organic farming, therefore effective seed treatment methods are urgently needed. Physical methods have efficacy against a number of seed-borne pathogens, but may have adverse effects if applied at too high intensity. Thermal treatment in water has the widest application. To control the loose smuts of wheat and barley it is still the only available non-chemical sanitation method. Other physical treatment methods with practical relevance in cereals are hot humid air and electron treatment. Hot water treatment is also known to control different seed-borne pathogens of vegetables. Various preparations of microorganisms, plant extracts and other agents of natural origin have been and are... |

| White clover soil fatigue is an increasing problem in Danish organic dairy farms. The clover cyst nematode (Heterodera trifolii) has been found to play a major role in the problem. Grassland legume species less readily attacked by H. trifolii and less favourable for its reproduction than white clover may offer possibilities for relieving the soil fatigue. In 2005, screenings were made of nine grass-land legume species / varieties in a field with a rather high level of H. trifolii infestation, pre-cropped with grass/white clover, and in a field with a low infesta-tion level, pre-cropped with maize. The species grouped in two: 1) White, red, alsike and kura clovers and lucerne had medium to high percentages of nematode attacks and numbers of nematodes... |

| Entomopathogenic nematodes are often found naturally infecting codling moth larvae. The effect of an autumn treatment with S. feltiae on the fruit damage in the following summer was evaluated by treating 4 different apple orchards in October 2004 and 2005 at application rates of 3.75; 2 and 1.5 billion nematodes in 4000 l / ha. In three of the treated orchards, one treated with 3.75x109 nematodes/ha the other two treated with 2e9 nematode/ha, reduction in fruit damage was around 50%. In the most heavily infested orchard, which was treated with 1.5x109 nematode/ha only 33% reduction in fruit damage was achieved. Compared to previous studies, this was the first assessing the effect on the fruit damage in the summer following the treatment rather than... |

| We have studied the emission of volatile organic compounds (VOCs) from young strawberry plants, cultivars Polka and Honeoye, after feeding by several strawberry herbivores under laboratory conditions. VOC profile of strawberry plants is highly dominated by green leaf volatiles (GLVs), which are released also due to mechanical damage. Our results reveal that strawberry has potential for inducible VOC defence, and this encourages testing the attractiveness of these strawberry VOCs to predatory mites. |
