| Die Beurteilung von Bodenqualität stellt für die landwirtschaftliche Praxis ein wichtiges Instrument für die Sicherstellung einer nachhaltigen Bodennutzung dar. Die Erhebung chemischer, physikalischer und biologischer Bodendaten werden routinemässig zu diesem Zweck herangezogen. Bodenbiologische Qualitätscharakteristika werden weitgehend durch Summenparameter wie Biomasse, Basalrespiration und Enzymaktivitäten erfasst. Solche Methoden haben sich als äusserst hilfreiche Instrumente erwiesen, jedoch sind sie nicht geeignet, um Strukturen mikrobieller Populationen, deren Biodiversität und spezifische Aktivität in Böden zu erfassen. Ein intaktes mikrobielles Bodengefüge und die Vielzahl der mikrobiellen Umsetzungsprozesse und Funktionen stellen wichtige... |

| A lysimeter experiment was conducted to investigate the effect of past and current management practices on soil microbial biomass, activity and community composition. Intact monolith lysimeters were taken from sites of the same soil type that had been under long-term organic and conventional crop management. They were subjected to the same crop rotation and managed according to best organic and conventional practices. Mineral N loss was determined in leachates and soil samples taken before the experiment and after 30 months were analysed for biological soil properties, including microbial diversity. Results indicated that leaching losses were similar for all treatments and that crop was the main influence on microbial biomass composition and size, while... |

| In a long-term field trial recently launched (2002-2011), located in Frick (878 mm mean annual precipitation) near Basle, Switzerland, the effect of reduced tillage on soil fertility indicators and crop yield was studied in a heavy soil (45% clay) in a crop rotation under organic farming conditions. We present the results of soil analyses after three cropping years (2002-2005). Soil organic carbon (Corg) increased over that period by 7.4% (+1.5 g Corg kg-1 soil) in the 0-10 cm soil layer in the reduced tillage plots, while it remained constant in the ploughed plots. Soil microbial carbon (Cmic) and dehydrogenase activity (DHA, TTC-reduction) were 28% higher in reduced-tillage plots in this soil layer. Biological soil quality as calculated by Cmic to Corg... |

| Organically managed agroecosystems rely in part on biological control to prevent pest outbreaks. Generalist predators (Araneae, Carabidae and Staphylinidae) are a major component of the natural enemy community in agroecosystems. We assessed the seasonal dynamics of major generalist predator groups in conventionally and organically managed grass–clover fields that primarily differed by fertilisation strategy. We further established an experiment, manipulating the abundant wolf spider genus Pardosa, to identify the importance of these predators for herbivore suppression in the same system and growth period. Organic management significantly enhanced ground-active spider numbers early and late in the growing season, with potentially positive effects of plant... |

| Soil enzymes were used to assess the impact of different treatments applied in four farms, each one with three vineyards as replicates, on soil functionality. 8 enzymes related to C, N, S and P cycling were measured and functional diversity indexes were estimated. Three treatments were compared: compost, green manure and dry mulching with respect to degraded and non-degraded soil. The four vineyards showed different enzymatic patterns and response to treatments. Vineyards with the largest difference between degraded and non-degraded soil have benefited more largely from the treatments. In particular, dry mulching seemed to be more effective than green manure or compost, with the exception of San Disdagio. However, the effect the short term. |

| 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,... |

| A consortium of plant-probiotic microorganisms is under investigation in open field conditions, at the ICEA-certified Organic Farm “La Carioncella”, for its ability to ensure durable soil fertility while buffering nutritional inputs reduction. The primary objective of our QLIF-WP333 three-years-long project is to produce scientific data to help farmers in managing soil probiotics, as a way to reduce inputs, production costs, while keeping quality and sustainability of organic and low-input tomato production systems. |

| Bodemkwaliteit is een containerbegrip dat biologische, chemische en fysische componenten omvat. Bodemgezondheid is een nauwer begrip dat beschreven kan worden vanuit een ecosysteem benadering. De begrippen stabiliteit en zelfregulatie, vitaliteit, ecologische veerkracht, organisatiegraad en biodiversiteit worden ten opzichte van elkaar gepositioneerd. Ziektewerendheid is een weer nauwere invulling van het begrip bodemkwaliteit en heeft uitsluitend betrekking op het vermogen van gronden om, ondanks de aanwezigheid van pathogenen, de expressie van de pathogeen in het gewas laag te houden. Negen mechanismen waarop de ziektewerendheid gebaseerd kan zijn worden beschreven. Het feitelijk vaststellen (meten) van ziektewerendheid gebeurt in biotoetsen met... |

| Le sol, composante du Terroir doit être considéré comme une ressource non renouvelable essentielle au fonctionnement des agro‐écosystèmes. Or, les sols viticoles sont particulièrement vulnérables aux dégradations. L’objectif central de ma thèse est donc d’évaluer comment les pratiques viticoles affectent la qualité des sols dans le Languedoc‐Roussillon. Pour ce faire, j’ai d’abord évalué la qualité des sols sur 164 parcelles présentant une grande variabilité de pratiques culturales et réparties sur 9 zones pédologiques très diversifiées. Puis, j’ai évalué la vitesse de changement de la qualité des sols par l’analyse de 23 parcelles d’une zone homogène converties progressivement en viticulture biologique depuis un maximum de 17 ans. Plusieurs indicateurs... |

| A laboratory mesocosm experiment was performed to study the effects of copper-enriched sewage sludge application on a mesofauna community. For 12 weeks, characteristics and changes in this defined and artificial mesofauna community structure were monitored as well as the dynamics of leaf litter decomposition. The mesofauna community comprised six species of Collembola (Folsomia fimetaria, Isotomurus prasinus, Lepidocyrtus cyaneus, Mesaphorura macrochaeta, Parisotoma notabilis, Protaphorura armata), two species of acari Oribatida (Achipteria coleoptrata, Adoristes sp.), one species of acari Gamasida Hypoaspis aculeifer) and one species of enchytraeid (Enchytraeus crypticus). Three treatments included the addition of 22 g dry weight (DW) sludge spiked with... |

| The effects of ecological vs. conventional farming on several biological, chemical and physical soil properties were investigated at the arable test site Gülzow (Northeast Germany). After ten years of ecological farming increased activities of dehydrogenase, β-glucosidase and alkaline phosphatase in the soil were measured. Low effects on the chemical soil properties like content of Corg, Nt and soil organic matter and no significant effects on physical soil properties like density, porosity and water retention were observed. -- (Sprache des Volltextes: Deutsch) |

| A six-year study was carried out in an organically managed orange orchard located in Sicily (Southern Italy) to assess the effect of compost and organic fertilizers utilisation on soil quality. Adopting a randomized-block experimental design with three replicates, four treatments were carried out. In treatments 1 and 2, two different composts (C1 from distillery by products and C2 from livestock wastes) were applied. The plots of treatment 3 were fertilized using dried poultry manure. The control treatment was fertilized with mineral/synthetic fertilizers. In order to verify the hypothesis that composts and organic fertilizers improve soil fertility, soil quality was evaluated by selecting dynamic soil parameters, as indicators linked to C and N cycles.... |

| Mit dem Ziel, ökologische Bodenbewirtschaftungsverfahren zu erforschen, zu demonstrieren und das erarbeitete Wissen an die Praxis und Beratung weiterzugeben, wurde 1994 in Wörrstadt/Rheinhessen das Projekt Ökologische Bodenbewirtschaftung (PÖB) gestartet. Das auf zehn Jahre angelegte Projekt wird hauptsächlich durch das Land Rheinland-Pfalz finanziert und gemeinsam von der Stiftung Ökologie & Landbau und der Landesanstalt für Pflanzenbau und Pflanzenschutz, Mainz, durchgeführt. Bei dem Projekt werden regelmäßig erfasst: – Textur, Gefüge und Durchwurzelbarkeit des Bodens; – Luft- und Wasserhaushalt; – Stoff-Flüsse im Boden; – biologische Aktivität und biologische Vielfalt im Agrarökosystem. Dabei werden vergleichend die Einflüsse einer intensiven,... |

| Legume biomass or pulse meal may be considered as alternatives to farmyard manure (FYM) in organic farms with small scale animal husbandry or in stockless organic farms. From 1996 a field trial was established on a poor sandy soil to compare plant based organic fertilisers, FYM and inorganic fertilisers, each applied at 100 kg ha-1 N. Additionally, FYM was tested at a higher rate of 170 kg ha-1 N. Average soil organic carbon content in topsoil (Corg) of the last crop rotation period (2002-05) is compared to that in 1996. Corg remained at the same level of 0.78 % only with FYM, while plant based and inorganic fertiliser decreased carbon contents to 0.74 and 0.72 % Corg, respectively. The higher FYM rate increased Corg up to 0.84 %. Based on these results,... |

| Ved Norsk senter for økologisk landbruk (NORSØK) bygges det opp kompetanse innen feltet biologisk mangfold, blant annet om virvelløse dyr på og i jordbruksjord. Reidun Pommeresche har utarbeidet denne rapporten som en del av denne kompetanseoppbyggingen. Rapporten er basert på et litteraturstudium. Hensikten er å presentere en del temaer angående livet i jordbruksjord, med hovedvekt på jordfaunaen i lys av økologisk landbruk. Bakerst i rapporten finnes en ordliste som vil være nyttig for den som er lite kjent innen fagområdet. Økt kunnskap om livet i jorden, øker mulighetene for en bedre forvaltning av det naturlige mangfoldet i norsk landbruksjord og bidrar til interessant og nyttig kunnskap for utviklingen av økologisk landbruk. Dette ved å belyse hvilke... |
