| Das Umbrechen einer Wiese auf maximal 10 cm Tiefe ist eine grosse Herausforderung. An einer Maschinenvorführung des FiBL wurden zwei Pflugmodelle (Överum Variflex, Rumpstad Stoppelploeg), zwei Flachgrubber (Treffler TG 300, Horsch Terrano 3 FX) sowie zwei zapfwellengetriebene Geräte (Rath Geohobel 230, Howard Rotavator 500) im Einsatz verglichen. Alle Maschinen konnten unter den gegebenen Bedingungen die Kunstwiese auf einer Tiefe von maximal 10 cm umbrechen, lieferten jedoch unterschiedliche Resultate. Der Film zeigt, wie die verschiedenen Geräte die Aufgabe bewältigen. Welche Maschine auf welchen Betrieb passt, hängt stark von den Bodenverhältnissen, dem Unkrautdruck und den angebauten Kulturen ab und muss gut überlegt sein. Technische Daten zu den... |

| The work aims to investigate the effects of different soil management strategies on carbon sequestration and total nitrogen in areas of vineyards suffering from loss of soil functionality. Treatments, selected for inter-row management, to re-install soil functionality were based on compost or other organic amendments (COMP), green manure (GM), and dry mulching (DM) strategies using winter legumes and cereals. Cover crops were seeded in fall and mown in late spring, leaved in the ground for mulching in DM or incorporated into the uppermost soil layers in GM. Such approaches were investigated in six vineyards in Italy, six in France, and two vineyards in Slovenia and Turkey. The results showed that COMP significantly increased total organic carbon (TOC)... |

| Der Vorsorgewert wurde nur von Cr überschritten. Es zeigt sich, dass das Verhältnis von Schadstoff zu Phosphor eine wichtige Rolle spielt. Von Düngern mit einem geringen P-Gehalt, wie den Komposten, muss eine größere Menge ausgebracht werden, was in dieser Berechnung zu einer höheren Schadstoffanreicherung führte. Grüngutkompost hatte das höchste Akkumulationspotenzial für alle Schwermetalle, nur bei Cadmium wurde er von Triplesuperphosphat übertroffen. Vermutlich ist die atmosphärische Schermetallbelastung von Grünschnitt in Städten und entlang von Straßen besonders hoch und konzentriert sich im Kompost. Die Schadstoffgehalte der Dünger können, je nach Ausgangssubstraten, unterschiedlich sein. Als Phosphordünger eingesetzt, hatten Struvite, Fleisch- und... |

| Frente ao modelo de modernização da agricultura, centrado no uso intensivo do solo, agricultores enfrentam problemas de conservação de suas terras. Esses problemas associados à produção de fumo, em áreas de alta fragilidade ambiental, aumentam a suscetibilidade dos solos à degradação. A Qualidade do Solo (QS) é um fator importante para o desenvolvimento de uma agricultura sustentável e pode ser avaliada através de indicadores. Este trabalho objetiva promover a construção do conhecimento em relação à QS, com o intuito de definir um conjunto de indicadores a fim de entender e avaliar aspectos relacionados ao uso, manejo e conservação do solo. Para isso quatorze unidades agrícolas familiares localizadas no município de Canguçu-RS foram estudadas. O... |

| This webinar is focused on nutrient management on organic systems. It is addressed to US farmers, especially in the part dedicated to regulations. Agronomic information presented by the relator will be useful also for European organic farmers, both experts and newcomers. It is organised in sections: US regulations; evaluation of crops nutrient requirements; evaluation of nutrients release from organic matter, amendments and cover crops; fertilization, timing and application methods; leaching and runoff risk. Data values are presented in US units of measure: pounds per acre. The conversion factor to kg per ha is nearly 1 (1.12), so quite straightforward. |

| 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... |

| Zusammenfassung Die nachhaltige Erhaltung und Steigerung der Bodenfruchtbarkeit ist für ökologisch wirtschaftende Betriebe von höchster Bedeutung. Im Öko-Landbau hängt das Niveau der Bodenfruchtbarkeit – abgesehen von den kaum zu beeinflussenden standörtlichen Gegebenheiten – sehr von der Leistungsfähigkeit der Leguminosen (N2-Fixierungsleistung, Durchwurzelungsvermögen) ab. Sie haben somit die Schlüsselstellung für die Verbesserung des Bodenfruchtbarkeitsmanagements im Öko-Landbau, speziell im Marktfruchtbau. Leguminosen werden allerdings stark durch bodenbürtige Pathogene beeinträchtigt. Auch die Art der Bodenbearbeitung, die im Öko-Anbau vergleichsweise intensiv ist, und das Befahren der Böden haben einen Einfluss auf die Bodenfruchtbarkeit, da bekannt... |

| Abstract - In our research we have evaluated a series of soil indicators to determine the correlation between individual soil properties in organic farming. Regression analysis has proven that the biological activity of the soil on organically farmed areas (grasslands) as expressed by respiration is mainly influenced by the bulk density, moisture, porosity, humus content, the proportion of cation exchange capacity and total nitrogen content. The multiple regressions have proven the important dependency of basal respiration to the moisture, bulk density and total nitrogen. The supply of organic matter to the soil environment, thus greatly influences the studied soil biological activity. Similar dependences were visible in the results of both conventional... |

| Composts can influence soil fertility and plant health. These influences can be positive or negative, depending of the quality of the composts. Some practitioners already make use of the positive effects on plant health. For example, they use composts to protect their plants against soil borne diseases in substrate, or to detoxify and reactivate soil after steaming. In order to estimate the potential of Swiss composts to influence soil fertility and plant health positively, we analyzed one hundred composts representative of the different composting systems and qualities available on the market. The organic substance and the nutrient content of the composts varied greatly between the composts; the materials of origin were the major factor influencing... |

| No-tillage (NT) and reduced tillage (RT) systems are well-known management tools for reducing soil erosion and improving soil fertility. NT and RT may improve the environmental and economic performance of organic farming, but they are still not common practice among organic farmers. This paper presents the effects of tillage [RT versus conventional tillage (CT)], fertilization (slurry versus manure compost) and biodynamic preparations (with versus without) on soil fertility indicators such as soil organic carbon (Corg), microbial biomass and microbial activity, soil nutrients and nutrient budgets in an organic farming system during the first six-year crop rotation period of a long-term experiment on a clayey soil in a temperate climate. RT caused... |

| Understanding organic management practices is a key in developing sustainable organic farming systems. We report the results of four different organic fertilization strategies in a field trial on yields, soil quality and economic performance. We found highest yields and economic performance in two direct plant feeding strategies. One of these strategies, a newly developed strategy based on biowaste compost (GFT) and an additional fertilizer performed well in terms of yields but looks also very promising in terms of soil quality and biodiversity. The economic perspective of this strategy renders it promising in regions with little animal manures. |
