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... |

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... |

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... |

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... |
