Thanks to positive interactions between species, growing mixtures of cover crops allows improving the ecosystem services provided by cover crop cultivation. In this study, the influence of species diversity but also of species identity and mixture composition on cover crop biomass production and its stability in diverse growing conditions was studied. Several field experiments (varying soil type, preceding crop, soil tillage, sowing density, nitrogen fertilization and spatial replication) were set up in Switzerland during the period 2013−2016. In these experiments, the performance of cover crop species grown as sole crops was compared to that of multispecific mixtures. Part of these experiments followed a simplex design in which four cover crop species... |

Conservation agriculture is arising as an alternative to conventional agriculture with the aim to have a reduced impact on the environment. This includes the use of cover crops to conserve soil quality by limiting soil erosion, adding organic matter, and enhancing soil nutrient content, as well as water availability, which are all factors that can greatly influence the presence of soil organisms. In the current study, we investigated whether winter cover crops can enhance the persistence of entomopathogenic nematodes (EPN) over the winter season. In a first trial we augmented EPN populations in plots without (bared) and with the cover crops, pea (Pisum sativum) or mustard (Brassica juncea). In late autumn, individual mini-plots in each of the three... |

To address the influence of soil tillage reduction on crop yield and soil properties, an experiment was set up in 1969 in the western part of Switzerland. A conventional tillage treatment with plough was compared to a minimum tillage treatment and a deep non inversion tillage treatment, converted to no till in 2007. Evolution of crop yield through time was investigated, as well as the soil properties in 2013. Mean soil properties and their stratification with depth were assessed. The results showed that, after 44 years, globally, all tillage treatments allowedtomaintainsimilaryieldsinthelongterm.However,duringthesametime,soilpropertieshavechanged deeply. Soil organic carbon has decreased compared to the initial situation, in all treatments except in the... |

As a key-element of conservation agriculture, the occasional or systematic suppression of full-inversion ploughing implies an adaptation of the cropping system. To assess the ability of cover crops to control weeds in a subsequent maize crop grown with reduced tillage, three annual experiments were implemented at the research station of Agroscope Changins, Nyon, Switzerland. Ten non-wintering cover crop (CC) species were sown in mid-summer and compared to a bare soil treatment in strip-plot experiments including different weeding strategies according to integrated weed management rules. In case of a predictable impasse for weed control, an alternative management option was chosen 1) at the end of winter: total herbicide application instead of no... |

Soils are of vital importance for sustainable food production. In order to maintain or improve soil quality, it is necessary to develop strategies for a sustainable use of soil. Alternative cropping practices such as reduced tillage and improved crop rotation are more and more adopted with the aim of decreasing the impact of agriculture on the environment. However, their on-the-ground impact in Swiss farming systems still has to be assessed. In this study, we quantified the impact of three farming systems (conventional farming, no-till, and organic farming) on plant and soil chemical, biological and physical properties. Our study included 20 fields for each farming system. All selected fields were cultivated with winter wheat the year of sampling. Soil was... |

There is an urgent need to identify and evaluate management practices for their biophysical potential to maintain productivity under climate change while mitigating greenhouse gas (GHG) emissions from individual cropping systems under specific pedo-climatic conditions. Here, we examined, through DayCent modeling, the long-term impact of soil management practices and their interactions on soil GHG emissions and GHG intensity from Swiss cropping systems. Based on experimental data from four long-term experimental sites in Switzerland (Therwil, Frick, Changins, and Reckenholz), we robustly parameterized and evaluated the model for simulating crop productivity, soil C dynamics and soil N2O emissions across a range of management practices and pedo-climatic... |

One of the primary challenges of our time is develop sustainable farming systems that can feed the world with minimal environmental impact. Some studies argue that organic farming systems are best because these have minimal impact on the environment and are positive for biodiversity. Others argue that no-tillage systems are better because such systems save energy and preserve soil structure and quality. A third group argues that conventional farming systems are best because yield per hectare is highest. However, so far, systematic comparisons of major arable production systems are rare and often it is difficult to compare the advantages and disadvantages of farming systems in a systematic way due to differences in soil/site characteristics and management.... |

Cette étude présente un indicateur agro- environnemental de la couverture du sol développé dans le cadre du monitoring agro-environnemental mis en place par l’Office fédéral de l’agriculture (OFAG). Cet indicateur est construit de façon à refléter les pratiques agricoles telles que le type de cultures, la rotation des cultures et les pratiques culturales. Il intègre à la fois des données techniques et des données issues de simulations faites à l’aide d’un modèle de culture. Cet outil a été appliqué aux données issues du Dépouillement centralisé des indicateurs agro-environnementaux (DC-IAE), ce qui représente en moyenne 226 exploitations sur cinq années. Les résultats montrent qu’une exploitation de grandes cultures n’atteint en moyenne que 62% de... |

Growing mixtures of species instead of sole crops is expected to increase the ecosystem services provided by cover crops. This study aimed at understanding the interactions between species and investigating how they affect the performance of the mixture. Four species were combined in six bispecific mixtures in a field experiment. The performance of each species when grown in a mixture was compared to its performance as a sole crop at different sowing densities, to characterise the influence of intra- and interspecific competition for each species. Intra- and interspecific competition coefficients were quantified using a response surface design and the hyperbolic yield-density equation. Interactions between the four species ranged from facilitation to... |

In dieser Studie wird ein auf dem Bodenbedeckungsgrad beruhender Agrarumweltindikator vorgestellt, der im Rahmen des vom Bundesamt für Landwirtschaft (BLW) lancierten Agrarumweltmonitorings entwickelt wurde. Dieser Indikator ist so angelegt, dass er die landwirtschaftliche Praxis – wie die Art der Kultur, die Fruchtfolge und die Anbaumethode – einbezieht. Er berücksichtigt gleichzeitig technische Daten und Daten aus einem Simulationsmodell. Dieser Indikator wurde auf Daten der Zentralen Auswertung der Agrarumweltindikatoren (ZAAUI) angewendet, in der durchschnittlich 226 Betriebe über fünf Jahre erfasst sind. Die Ergebnisse zeigen, dass ein Ackerbaubetrieb nur einen durchschnittlichen Bodenbedeckungsgrad von 62% erreicht, deutlich weniger als der fast... |

In arable systems, cover crops provide multiple ecosystem services involved in soil protection and fertility. They can efficiently compete against weeds, control erosion or recycle nutrients. The supply of these services is however largely dependent on cover crop growth as most of the services are related to biomass production. The choice of a cover crop adapted to the growing conditions is thus essential. Growing mixtures instead of sole crops is expected to be a way to overcome variable growing conditions and to insure high biomass production.Different field trials have been conducted from 2013 to 2016 in Nyon, Switzerland to assess cover crop biomass production and stability, and their influence on the following crop. Indian mustard, field pea, black... |

Les cultures intermédiaires multi services, ou CIMS, jouent un rôle essentiel en agriculture biologique (AB) du fait des nombreux services écosystémiques qu’elles peuvent rendre. La capacité des CIMS à apporter des nutriments à la culture suivante est particulièrement intéressante en AB en raison de la faible disponibilité en engrais. Les CIMS visent également de maintenir la teneur en matière organique des sols essentielle à leur fertilité en compensant les exportations des récoltes. Elles représentent aussi un moyen de lutte efficace contre les bioagresseurs, en particulier les adventices, par une compétition directe pour les ressources ou par des modifications du milieu de croissance. Le contrôle des maladies et ravageurs par les CIMS se fait... |
