| Gardens are hot spots for urban biodiversity and provide habitats for many plant and animal species, both above- and below-ground. Furthermore, gardens provide a wide range of ecosystem services, including carbon (C) storage and nutrient cycling. Although the soil is the foundation of sustainable gardens providing those ecosystem services, very little is known about the consequences of garden management on soil quality. Here we present a comprehensive assessment of urban garden soil quality, including biotic and abiotic site characteristics combined with land-use history and garden management information in a multivariate evaluation. A set of 44 soil quality indicators was measured at 170 sites of 85 gardens in the city of Zurich, Switzerland, comprising... |

| Aims Belowground legume nitrogen (N) composed of roots and rhizodeposition is an important N input to soils, but published data of belowground N vary broadly, probably due to extrapolation from short-term experiments and dissimilar growing conditions. We quantified belowground N inputs of red clover (Trifolium pratense L.) during two consecutive years in a clover-grass sward along a soil nutrient availability gradient. Methods We established a red clover-perennial ryegrass (Lolium perenne L.) model sward in microplots located in field plots of the DOK experiment, which has a 33-year history of organic and conventional cropping, resulting in a soil nutrient availability gradient. Four treatments were examined: the zero fertilisation control, bio-organic... |

| Naranjilla (Solanum quitoense) is a perennial shrub plant mainly cultivated in Ecuador, Colombia, and Central America where it represents an important cash crop. Current cultivation practices not only cause deforestation and large-scale soil degradation but also make plants highly susceptible to pests and diseases. The use of arbuscular mycorrhizal fungi (AMF) can offer a possibility to overcome these problems. AMF can act beneficially in various ways, for example by improving plant nutrition and growth, water relations, soil structure and stability and protection against biotic and abiotic stresses. In this study, the impact of AMF inoculation on growth and nutrition parameters of naranjilla has been assessed. For inoculation three European reference AMF... |

| Arbuscular mycorrhizal (AM) root colonization was studied in a long-term field trial in which four farming systems currently in use in Switzerland were continuously applied to a randomized set of plots at a single field site from 1978 till 1993. There were two low-input farming systems (organic and bio-dynamic) and two high-input (conventional) farming systems (according to Swiss guidelines of integrated plant production with and without farmyard manure). The systems had an identical 7-year crop rotation and tillage scheme and differed essentially only in the amount and type of fertilizer supplied and in plant protection management. The percentage of root colonization by AM fungi was determined in field samples 2–3 times over the growing season in crops in... |

| Despite the increase in organic cropland, knowledge on the impact of organic farming on soil-derived nitrous oxide (N2O) and methane (CH4) emissions is rather limited. To improve the knowledge base, N2O and CH4 fluxes were investigated in a 571 day lasting cropping sequence in the “DOK” field trial. Two organic and two non-organic farming systems and an unfertilized control were chosen. For the whole monitoring, the two organic systems combined emitted 40% less N2O than the two non-organic ones cumulated on area-scale. Yield-scaled cumulated N2O emissions were nearly 10% lower for the organic systems combined, despite the yield gap of 27%. We found that besides N input, management induced soil quality properties drive differences in N2O emissions between... |

| N2O is a major greenhouse gas and the majority of anthropogenic N2O emissions originate from agriculturally managed soils. Therefore, developing N2O mitigation strategies is a key challenge for the agricultural sector and biochar soil treatment is one reported option. Biochar's capacity to increase soil pH and to foster activity of specialized N2O reducers has been proposed as possible mechanisms for N2O mitigation. An experiment was undertaken to investigate whether changes in the community composition of N2O reducers was observed under field conditions after biochar application. The study objective was to assess the abundance and taxonomic composition of the functional marker genes nosZ and nosZ –II across a vegetation period of Zea mays L. after biochar... |

| Results › Carbon mineralization rates were highest in maize straw and lowest in pyrochar amended soil. › Pyrochar showed even lower CO2 fluxes than non-amended soil. › Initial mineralization rates of maize straw and hydrochar were higher in soil M, whereas in Soil D the pyrochar was decomposed slightly faster. › Hydrochar derived carbon was readily incorporated in the microbial biomass of both soils, pyrochar resisted nearly completely. › Comparison of carbon pools CO2 , Cmic and Corg at day 12 and day 205 shows that a stabilsation of maize feedstock of more than a double could be achieved with HTC and far beyond that scale with pyrolysis. |

| Mit der Umstellung des Gutes Rheinau von konventionell integrierter Bewirtschaftung auf bio-dynamische Wirtschaftsweise im Jahre 1998 wurde ein Monitoring der Bodenfruchtbarkeit begonnen, dass die biologische Veränderung im Boden während der Umstellungsphase dokumentieren sollte. Die ersten Bodenproben wurden 1999 auf drei Ackerschlägen und einer permanenten Naturwiese gezogen und dann wurden im Jahr 2002, 2005 und 2010 auf den in 1999 definierten Teilflächen je Schlag weitere Bodenproben entnommen. Neben mikrobiologischen Bodenparametern (mikrobielle Biomasse, Basalatmung, Dehydrogenaseaktivität) wurden die Regenwurmpopulationen und auch chemische Bodenparameter und lösliche und nachlieferbare Fraktionen wichtiger Nährstoffe ermittelt. Ausserdem erfolgte... |
