| Organic farming systems, characterized by special attention to soil fertility, recycling techniques and low external inputs, gained increased significance in recent years. As a consequence, there is a growing demand for varieties adapted to organic and/or low input farming. The objectives of the present study were to (i) compare the testcross performance of segregating maize (Zea mays) populations under established organic (OF) and conventional farming (CF) systems, (ii) determine quantitative genetic parameters decisive for the selection response under OF vs CF conditions, and (iii) draw conclusions for breeding new varieties optimally adapted to OF. Testcross performance of four different material groups of preselected lines (90 lines per group) derived... |

| There is an urgent need to analyse the term soil quality in more detail. Most frequently, it is used to describe soil attributes. The term should be used for this purpose only when related to the sustainability concerns (i) soil productivity, (ii) impact on the environment, and (iii) effect on human health. The soil quality concept has been adopted mainly as a technical framework for grading soil and evaluating management effects. We advocate more focus on soil quality as a cognitive concept associated with sustainability. Grading of soils by indicators is difficult across soil types, climates and cropping systems. The indexing of soil quality indicators introduce a significant loss of information on the complex agroecosystem. The contributions to the... |

| Although existing as a concept (with a few farmers following it) since the 1920s, it was in the 1970s and 1980s that organic farming evolved as a social movement pursuing an alternative style of food production and consumption. It is, however, a particular social movement, in so far that it has not only developed as an alternative idea to mainstream agriculture, but it has put its innovative ideas into a concrete, real practice. This practice has since continuously been developed further by farmers, engaged consumers, environmental groups, and researchers. In addition, politics have taken an interest in organic farming, and support organic farming in many countries. The implications of acting in such a real practice becomes manifest in the ‘triple logic’... |

| Fresh fruit consumption is being promoted for health reasons in North America, Europe and other regions. Consumers are responding, as evidenced by the 20 percent increase in per capita fruit consumption in the past 30 years. US consumers have increased fruit consumption by 23 percent, but they still consume half the amount recommended by the dietary guidelines of the United States Department of Agriculture (USDA). Fruit production often requires significant intervention with pesticides to control pests and diseases. Thus, health conscious consumers increasingly see organic fruit as a logical package. Fruit and vegetable sales account for about 40 percent of the retail sales of organic foods in the US (93 percent of this is fresh produce), with fruit... |

| Various stakeholders involved with sustainability certification are interested in knowing whether certification really fulfills its promises. Business managers who have to determine what type of products to source, consumers who are concerned about making appropriate buying decisions for themselves and their families, producers who think about obtaining certification, and sustainability standard initiatives that themselves need arguments to support their certification programs. A recent study conducted by FiBL (Niggli et al 2011) reviewed the current state of empirical research on environmental, social, and economic impacts of sustainability certification in the agricultural sector. One result of the study was that a disproportionate number of research... |

| This chapter includes information on the development of the free range and the organic egg production and their market shares in different countries. Consumer behaviour is investigated particularly in relation to the price and availability of non-cage eggs. Regulations on the production of free range and organic eggs and their present and future impact are examined. Nutrient supply, animal welfare, productivity, safety and environmental impact of the types of egg production are covered with a focus on the effects of using different forage materials. Egg quality parameters of egg shell, sensory properties, yolk colour and carotenoid content, egg protein, and egg products are also discussed. |

| The opportunities to grow the "organic pie" are substantial for both China and Australia. However the challenges and the opportunities are far from identical, although the goals of growing the production area, increasing the market awareness, fostering consumer confidence in certification and labeling, broadening the product offering and availability, and increasing sales are shared issues. Some of the aspects of organics opportunity and challenge are examined in this book chapter. Comparative statistics between Australia and China are presented in Table 3.1. |

| Results - It is necessary to improve the information to the public (who are the taxpayer and pay the subsidies) about organic farming as a system, that improves animal health and welfare. - Consumers must get accurate information about the organic products they buy. - Producers should be informed about organic farming before they convert (so they know what to expect): they should be told about the regluations and pointed to the available information about organic farming. - Veterinarians should be informed (part of the teaching curriculum in vet schools) about the holistic system, the importance of preventive health management on organic farms and about alternative treatments. - In communication to the policy makers (the government), organic... |

| Eutererkrankungen sind nicht der Krankheitskomplex, der an erster Stelle genannt wird, wenn man an Krankheiten bei kleinen Wiederkäuern denkt. Trotzdem haben sie vermutlich eine gleich große Bedeutung wie bei Milchkühen. Ganz besonders wenn man die Milchleistungsminderungen in Betracht zieht, welche durch die subklinische, d. h. durch visuelle Beurteilung des Vorgemelks und des Euterzustandes nicht erkennbare, Form der Mastitis betrachtet. In der erwerbsmäßigen Milchschaf- bzw. Milchziegenhaltung kommt der Gesunderhaltung des wichtigsten „Betriebsmittels“, dem Euter, somit eine ganz besondere Bedeutung zu. Dabei muss die Prophylaxe in Form einer tiergerechten Haltung, leistungsgerechten Fütterung sowie eines Euter schonenden Milchentzugs stets im... |

| We implemented a system GDV Assistant (Gas Discharge Visualisation Technique) for parameterization and visualization of coronas of humans and plants. Besides standard parameters, developed by the team of Prof. Korotkov, the program includes some additional numerical parameters. In last few years in several studies we recorded coronas of apple tree leaves and fruits in order to verify and compare their vitality under different conditions. We used GDV Assistant for preprocessing and for numerical parameterization of coronas and we used various machine learning algorithms for analyzing the databases of parameterized corona pictures. The results of our studies show that coronas of leaves and fruits give useful information about the stress status of... |

| Ziel des themenbezogenen Netzwerkes ‚Forum Pflanzenschutz im ökologischen Landbau’ [1] ist es, den Austausch von Informationen, Erkenntnissen, Problem- und Fragestellung auf und zwischen den verschiedenen Ebenen aufzubauen bzw. zu verbessern. Dies geschieht im Rahmen von vorbereiteten Workshops, die unter Beteiligung der relevanten Akteure wichtige Fragestellungen des Pflanzenschutzes im Öko-Landbau diskutieren. Die zu diskutierenden Punkte umfassen z. B. praktische Probleme des ökologischen Landbaus im Bereich Pflanzenschutz, aktuelle Forschungsvorhaben in diesem Feld, administrativ-politische Fragestellungen sowie Fragen über geeignete Mittel zu Pflanzenschutzzwecken im ökologischen Landbau. |

| Measurements of crop yield and soil carbon in the Bad Lauchstädt long-term fertiliser experiment were analysed with the FASSET model. The model satisfactorily predicted yield and soil carbon development in four treatments with no fertiliser, mineral fertiliser, farm yard manure and farm yard manure plus mineral fertiliser, respectively. However, there was a residual between the observed and simulated yield, which was correlated with year. This could be attributed to an increase in observed yields during the last six decades. Scenario analysis showed that the most probable explanation for this yield increase was the use of new crop varieties and/or pesticides, while the increase in atmospheric CO2 and changes in local N deposition were of lesser importance.... |
