Phosphorus forms in fertilized arable soil profiles and related 33P uptake
(2019-09-13)
Arable soils usually store several thousand kg phosphorus (P) per ha, thus far exceeding the recommended P fertilizer dose to sustain crop yields. However, the soil profile is frequently not considered in fertilizer ...
Demand for organic food in Switzerland
(2019-08-20)
The aim of this dissertation is to better understand the functioning of the organic food market in Switzerland. Over the last three decades the market for organic food in Switzerland has developed positively and continues ...
Studies on nematode factors activating the plant immune system
(2019-05-15)
Plant-parasitic nematodes are destructive pests causing crop losses accounting for billions of dollars annually. To defend against invading pathogens plants rely on innate immune system which involves the recognition of ......

The role of Rboh-mediated ROS and glutathione in plant-nematode interaction
(2019-11-05)
Aerobic life forms are known for constant production of reactive oxygen species (ROS), the deleterious end-products of aerobic energy that are able to provoke cellular damage. The ROS production in plants can be triggered ......
Alle Formen aeroben Lebens produzieren Reaktive Sauerstoffspecies (ROS), Endprodukte der aeorben Energiegewinnung, die schwere Schäden an Zellen verursachen können. Die Produktion von ROS in Pflanzen kann darüber hinaus ......

Food waste reduction concepts for stakeholders in the food supply chain and auxiliary organizations
(2019-09-10)
The objective of this thesis was to develop concepts to support the reduction of food waste in the food sector. The concepts are targeted to private companies, such as manufacturing businesses, retailers, and large-scale ...
Untersuchungen zur Wirkung metallischer Nanopartikel auf Pflanzen
(2019-08-27)
Die zunehmende Verwendung von Nanopartikeln (Np) in Konsumgütern und industriellen Anwendungen löst im Hinblick auf deren mögliche Freisetzung in der Umwelt und die damit verbundenen Auswirkungen auf Ökosysteme und Organismen ......
The increasing use of nanoparticles (np) in consumer products and industrial applications raises concerns about their potential release into the environment and possible related impacts on ecosystems and organisms. Despite ......

Nitrogen sequestration in paddy and non-paddy soils formed from different parent materials
(2019-08-19)
Paddy soils exhibit low nitrogen (N) use efficiency. Prior research in this field suggested that paddy soils may sequester significant amounts of N in aged amino acids, microbial residues, or even in pyrogenic N. The ...
Partitioning Water Vapor Fluxes by the Use of Their Water Stable Isotopologues: From the Lab to the Field
(2019-09-04)
Water stable isotopes are powerful tracers for partitioning of the terrestrial ecosystem water vapor fluxes into process-based components, i.e. evapotranspiration (ET) into soil evaporation (E) and plant transpiration (T). ......
Analysis and mitigation of site-dependent effects in static and kinematic GNSS applications
(2019-10-08)
Satellitensignale unterliegen auf ihrem Weg von der Satelliten- zur Empfangsantenne einer Vielzahl an Einflüssen die zu Abweichungen führen. Heutzutage stellen in vielen Anwendungsbereichen insbesondere die stationsspezifischen ...
