| A yearly amount of 9.3x106t compost and digestate derived from separately collected organic waste is produced in the 25 European Union member states. The improvement of soil properties is a major benefit of compost application. However, little is known about the occurrence of organic pollutants in compost. In order to estimate the potential of Swiss composts and digestates to influence soil fertility and plant health, one hundred products representative for the different composting systems and qualities available on the Swiss market were analyzed in two research projects. In the first study, polycyclic aromatic hydrocarbons (PAHs), ortho substituted and dioxin-like polychlorinated biphenyls (PCBs, DL PCBs), polychlorinated dibenzo-p-dioxins and... |

| Pour résoudre localement le problème de surplus de déchets organiques livré sur l’installation genevoise de compostage et de méthanisation du site de Châtillon, un concept de collaboration avec des agriculteurs traitant une partie des intrants en bords de champs a été élaboré, puis mis en place fin 2007. Après une année, ce concept donne pleine satisfaction tant sur le plan de la qualité des composts produits que sur le plan du déroulement des opérations. Chaque partie impliquée sort gagnante de cette collaboration. Une collaboration réussie de cette ampleur est un exemple unique en Suisse. |

| Fertile soils are highly important for arable farming. To maintain soil fertility, crop rotation including legumes is applied, particularly in stockless farms. Yet, many commercial farms report yield reductions for legumes. The aim of the present study was to evaluate whether the causes for the observed soil fatigue can be narrowed down by a bioassay (modified differential diagnosis according to Bouhot) and whether this bioassay could be a useful tool to predict the suitability of a field to grow legumes. |

| Um den Einfluss von Kompost und Gärgut auf die Bodenfruchtbarkeit und auf das Pflanzenwachstum abschätzen zu können wurden hundert, für die Schweiz repräsentative, Proben untersucht. Die Gehalte an Nährstoffen und an Salz waren vom Ausgangsmaterialien abhängig. Die Gehalte an organischer Substanz sowie die Atmungs- und Enzymaktivitäten nahmen mit zunehmender Kompostreife ab. Bei einigen jungen Komposten konnten Stickstoffblockaden beobachtet werden. Der Nitratgehalt im Kompost erlaubt jedoch vorherzusagen, ob eine N-Immobilisierungsgefahr besteht oder nicht. Die Phytotoxizität der Komposte variierte auch bei den reiferen Produkten sehr stark. Dies weist auf die grosse Bedeutung der Rotteführung und der korrekten Lagerung der Produkte hin. Während die... |

| Les cultures maraîchères mettent, de par leur intensivité, le sol à rude contribution. Ceci peut avoir des effets négatifs sur sa fertilité en général et en particulier causer une augmentation de la pression des maladies telluriques. Pour remédier à ces problèmes, le compost de qualité offre une alternative très intéressante. Son action positive sur la santé des plantes est indirecte (entre autres en apportant un mélange d’éléments fertilisants équilibré et en améliorant la structure du sol, son aération et son bilan hydrique) et directe (la microflore bénéfique qu’il contient influençant l‘activité biologie du sol). Les effets positifs des composts ne se limitent pas à protéger les plantes contre les maladies telluriques, mais peuvent également s’observer... |

| This proceedings volume contains the papers presented at the CODIS 2008 congress held on 27 - 29 February 2008 in Solothurn (Switzerland).The composting and digestion of biogenic waste materials and the subsequent application of compost and digestate to soil contributes to nutrient recycling and renewable energy production. Moreover, compost and digestate can improve soil fertility and suppress plant diseases. On the other hand, compost and digestate may also contain a variety of pollutants hazardous to soil, such as heavy metals and organic contaminants.Compost and digestate have been thoroughly investigated in the framework of two associated projects entitled Organic Pollutants in Compost and Digestate in Switzerland and Effects of Composts and Digestate... |

| Composts can influence soil fertility and plant health. These influences can be positive or negative, depending of the quality of the composts. In order to estimate the potential of Swiss composts to influence soil fertility and plant health, one hundred composts representative of the different composting systems and qualities available on the market were analyzed. The organic substance and the nutrient content of the composts varied greatly between the composts; the materials of origin were the major factor influencing these values. The respiration rate and enzyme activities also varied greatly, particularly in the youngest composts. These differences decreased when the composts become more mature. Maturity, the degradation stage of the organic matter,... |

| The German Federal programme on organic farming and other forms of sustainable agriculture developed practical cultivation strategies with the aim of improving soil fertility and plant nutrition. During the five-year project, some new practical knowledge was gained. These findings are listed in the booklet. Reading this guideline should encourage farmers to intensify the cultivation of grain legumes. |

| Zvyšování půdní úrodnosti bylo pro průkopníky ekologického zemědělství základem veškerého jejich úsilí. Přesto zachování úrodné půdy mnohdy nebyla věnována dostatečná pozornost. Ekologické zemědělství je však na přirozené půdní úrodnosti závislé. Oslabená a poškozená půda nám nemůže poskytnout to, co od ní očekáváme. Udržet úrodnost půdy vyžaduje velkou péči. Předkládaná brožura ukazuje půdní úrodnost z různých úhlů pohledu. Naším záměrem však nebylo vytvořit obecně platný „návod k použití“. Informace mají být mnohem spíše podnětem k tomu, aby se o vztahu člověka k půdě smýšlelo jinak a aby se tento vztah utvářel ve prospěch budoucnosti. |

| Damping-off of spinach, caused by soil-borne pathogens, is one of the most serious problems in organic spinach production. To overcome these problems soil amendments based on specific strains of micro-organisms or based on organic material are proposed. In pot experiments under controlled conditions 14 microbial strains and six organic soil amendments were tested on their ability to suppress soil borne diseases and to improve plant stand establishment. In a subsequent field experiment with the best treatments, soil amendments with compost showed the best effect while products based on single strains of micro-organisms failed to improve plant stand establishment. It is concluded that under high disease pressure a diverse population of microorganisms as it... |

| The aim of this study was to investigate the potentials and limitations in restoring soil suppressiveness in disturbed soils. Soils from three sites in UK and Switzerland (STC, REC, THE) differing in their level of suppressiveness to soil-borne and air-borne diseases were γ-irradiated and this soil matrix was re-inoculated with 1% (w/w) of either parent native soil or native soil from the other sites (‘soil inoculum’). Suppressiveness to air-borne and soil-borne diseases was quantified by means of the host–pathogen systems Lepidium sativum (cress)–Pythium ultimum, an oomycete causing root rot and seedling damping-off, and Arabidopsis thaliana–Hyaloperonospora parasitica, an oomycete causing downy mildew. Soil microbial biomass, activity and community... |

| Bisher war es für Kompost und Gärgut in Ökobilanzen üblich, die Nährstoffe als Substitute von Mineraldüngern und die Schwermetalle als Belastungen einzusetzen. Im Vergleich zur Verbrennung, wo die organische Substanz vollständig mineralisiert und energetisch genutzt wird, gibt es bei Kompost und Gärgut eine Lücke: wie soll die organische Substanz bewertet werden? Zur Bewertung der organischen Substanz in Ökobilanzen gibt es zwei grundlegend verschiedene Vorgehensweisen: 1. Einsetzen der einzelnen Effekte wie Erosionsreduktion, weniger Zugkraftbedarf, bessere Wasserhaltekapazität, weniger Krankheitsanfälligkeit etc. mit jeweils entsprechenden LCA-Modulen 2. Globales Einsetzen von Substituten, welche die Effekte möglichst gut abbilden. Gegen die erste... |

| In 2002 and 2003 two randomized trials and three “on farm” trials where carried out to test the hypothesis that a single winter treatment could reduce the primary inoculum of Sooty Blotch sufficiently to prevent fruit disease during summer. copperoxychloride (0.2%-0.4%) and lime sulfur (4.0%-5.0%) were applied until run-off in March shortly before bud break. Assessments of Sooty Blotch incidence and severity where made immediately after harvest. The winter treatments with copperoxychloride did reduce disease severity during summer in one case. The treatments with lime sulfur reduced the disease level in three sites to some extent. However, winter treatments alone were not nearly as efficient as summer treatments. Therefore, we see no reason to... |
