| In einem Feldversuch auf zwei Standorten (Lehm, Sand) wurde in zwei Serien der Einfluss der Stroh-Aufbereitung auf dessen Umsatz im Boden untersucht. Die untersuchten Düngervarianten umfassten: Stroh (STR) sowie Stroh mit zusätzlicher Stickstoffgabe in Form von Hühnertrockenkot (STR+N), Rottemist (RM) und flüssigem, wie trockenem Gärrest (GRflüssig, GRtrocken) aus der Strohvergärung mit Hühnertrockenkot. Das Stroh der Varianten STR und STR+N wurde nach Ernte der Vorfrucht (Sommergetreide) eingearbeitet. Die restlichen Varianten wurden im Frühjahr appliziert. Um den Umsatz der Düngervarianten zu erfassen wurde die Produktion von CO2, N2O und CH4 in regelmäßigen Abständen an beiden Standorten gemessen. Zusätzlich erfolgte die Erhebung von Kohlenstoff- und... |

| Currently, the only effective treatment for cocoa (Theobroma cacao L.) infected with the cocoa swollen shoot virus disease (CSSVD) is to cut and replant infected trees. Hence, the development of preventive control measures and strategies to mitigate the severity of the disease are of utmost importance. While past research has mainly focused on resistance breeding, mild strain cross protection and vector control, diversification measures such as agroforestry have received relatively less attention, despite their potential to mitigate CSSVD severity. Therefore, we studied the effects of shade on CSSVD symptom severity, capsid damage and cocoa yield along a gradient of increasing shade tree abundance in smallholder cocoa farms in Ghana. Furthermore, we... |

| Die zunehmende Relevanz biomassebasierter Treibstoffe führt zu verstärktem Interesse an verschiedenen Pflanzen als Energielieferant (z.B. Mais und Zuckerrohr für Bio-Ethanol, oder Raps und Ölpalmen für Biodiesel). Ein grosses Potential für den Süden wird dabei Jatropha curcas, einer Pflanze mit sehr ölreichen Samen, zugesprochen. Gleichzeitig wird jedoch auch starke Kritik am Anbau von Jatropha geäussert. Dieses Merkblatt stellt das vorhandene Wissen zu Jatropha zusammen, betont die möglichen Vorteile, Nachteile und Wissenslücken, und gibt weiterführende Referenzen für eine vertiefte Auseinandersetzung damit an. |

| In a field trial comprising organic farming and minimum tillage management strategies in Scheyern, Germany, we evaluated the long-term (21-year) effects of organic farming (use of a diverse crop rotation with legume cover crop and without application of synthetic fertilizer or pesticides) and minimum tillage (6–8 cm depth) on the microbial community structure and microbial residues in Cambisols. Organic farming had a positive effect on microbial biomass, total phospho-lipid fatty acids (PLFA), Gram (+) bacteria, Gram (-) bacteria and the arbuscular mycorrhizal fungi (AMF) indicator PLFA 16:1v5 and amino sugars. The increase in presence of Gram (+) bacteria when compared to integrated farming was also reflected by increased content of bacterial muramic acid... |

| Climate change mitigation is urgent and adaptation to climate change is crucial, particularly in agriculture, where food security is at stake. Agriculture, currently responsible for 20-30% of global greenhouse gas emissions counting direct and indirect agricultural emissions), can however contribute to both climate change mitigation and adaptation. The main mitigation potential lies in the capacity of agricultural soils to sequester CO2 through building organic matter. This potential can be realized by employing sustainable agricultural practices, such as those commonly found within organic farming systems. Examples of these practices are the use of organic fertilizers and crop rotations including legumes leys and cover crops. Mitigation is also achieved... |

| The cocoa swollen shoot virus disease is a major factor limiting cocoa (Theobroma cacao L.) productivity for West African farmers. The only treatment against this disease is to cut infected trees and replant with disease-free planting material. Research has recommended the prevention measures: (i) cordon sanitaire (leaving 10-m-wide cocoa-free zone around cocoa), (ii) barrier cropping, (iii) using partly tolerant hybrids, and (iv) removing specific alternative host tree species. Here, we evaluate the current adoption of these measures and identify their adoption constraints. We conducted a quantitative survey with 396 farmers in the Eastern and Western Regions of Ghana, held six focus group discussions and hosted a multi-stakeholder validation workshop... |

| Anthropogenic greenhouse gas emissions have increased since the pre-industrial era, driven largely by economic and population growth, and are now higher than ever. This has led to atmospheric concentrations of carbon dioxide, methane and nitrous oxide that are unprecedented in at least the last 800 000 years. Their effects, together with those of other anthropogenic drivers, have been detected throughout the climate system and are extremely likely to have been the dominant cause of the observed warming since the mid-20th century. |

| Based on urgent needs for food security compounded by a changing climate which impacts and is impacted by agricultural land-use and food distribution practices, we explore the processes of action in implementing agroecological food systems. We identified the following characteristics for an agroecological food system: 1. Minimizing use of external inputs, 2. Extent of internal resource recycling, 3. Resilience, 4. Multifunctionality, 5.Building on complexity and incorporating greater systems integration,6. Contextuality, 7. Equity and, 8. Nourishment. We focus on the city-region food systems context, concluding with practical drivers for realizing more agroecological food systems in cityregion contexts. Agroecological food systems are widely... |

| N2O is a potent greenhouse gas with an atmospheric lifetime of 114 years which also contributes to ozone layer destruction. Mitigating N2O emissions is especially challenging to the agricultural sector that is responsible for the majority of anthropogenic N2O release. In order to develop effective mitigation strategies, a detailed understanding of drivers for N2O production and reduction in agriculturally managed soils is needed. Denitrification is recognized as one of the most important source processes for N2O emissions from soils. However, the last step in denitrification, the reduction of N2O to N2 is the only known sink for N2O in soil. Although the impact of single parameters on denitrification is quite well documented, there is still a knowledge gap... |

| It is anticipated that organic farming systems provide benefits concerning soil conservation and climate protection. A literature search on measured soil-derived greenhouse gas (GHG) (nitrous oxide and methane) fluxes under organic and non-organic management from farming system comparisons was conducted and followed by a meta-analysis. Up to date only 19 studies based on field measurements could be retrieved. Based on 12 studies that cover annual measurements, it appeared with a high significance that area-scaled nitrous oxide emissions from organically managed soils are 492 ± 160 kg CO2 eq. ha− 1 a− 1 lower than from non-organically managed soils. For arable soils the difference amounts to 497 ± 162 kg CO2 eq. ha− 1 a− 1. However, yield-scaled nitrous... |

| The majority of soil organic nitrogen (N) is bound in protein-like compounds and therefore its proteolysis in peptides and amino acids is considered the initial and rate limiting step of N mineralization. Proteolysis of N bound in organic fertilizer and subsequent provisioning for crops is a central element in agro-ecological intensification. Long-term farming system effects on N provisioning from organic fertilizer to crops and its underlying functional microbial communities were analyzed in experiments conducted in soils from the “DOK” system comparison trial (bio-Dynamic, bio-Organic, and “Konventionell”) subjected to optimal and future projected drought scenarios. A plant nutrition experiment using 15N labeled lupine as a fertilizer (green manure)... |

| Organic farming and agroforestry are considered as sustainable alternative agricultural practices for intensive agriculture. In a long-term field trial in Scheyern Germany, we evaluated the effects of 21-year organic farming and 4-year agroforestry (robinia and poplar) on microbial community and microbial residues. Microbial biomass and microbial community were determined by fumigation–extraction method and the analysis of phospholipid fatty acid (PLFA), respectively. Microbial residues were evaluated by the measurement of amino sugars. The results showed that organic farming had significantly positive effect on soil organic carbon (SOC) but that it tended to decrease microbial biomass C (MBC), PLFA functional guilds, muramic acid (MurN), and glucosamine... |

| Soil microorganisms guarantee numerous soil functions, such as nutrient cycling, soil structure formation and the regulation of soil pathogens. Restoring soil fertility and increasing stability of soil is an urgent call to farmers. Soils also serve as a habitat for an almost uncountable diversity of soil microbes, which often is closely linked to the above ground one. Active, well-structured soils guarantee sustainable yields and safeguard natural resources simultaneously. Farming systems as a whole, but also individual practices such as tillage, the use of organic manures and crop rotations have a strong influence on soil microbial activities and biodiversity. Long-term trials are ideal bases to identify effects of agricultural management on the soil... |
