Electron transfer reactions and their role in soil carbon cycling

Meret Aeppli

Electron transfer reactions are central to the transformation of energy in the environment and play an important role in biogeochemical element cycling. In soils, one of the main drivers of carbon cycling is the activity of organisms that utilize the energ ...

Reactions of hypobromous acid with dimethyl selenide, dimethyl diselenide and other organic selenium compounds: kinetics and product formation

Urs von Gunten

Selenium (Se) is an essential micronutrient for many living organisms particularly due to its unique redox properties. We recently found that the sulfur (S) analog for dimethyl selenide (DMSe), i.e. dimethyl sulfide (DMS), reacts fast with the marine oxida ...

Climatic and Ecological Impact of Greenlandic Glacial Outwash Plains

Devis Tuia, Julia Schmale, Nora Bergner, Ianina Altshuler, Gaston Jean Lenczner, Grace Emma Marsh

Warming in the Arctic is occurring at an accelerated rate compared to the rest of the world which is partially driven by ecological and climatic feedback loops. Accelerated glacial and ice sheet retreat in Greenland drives increased development of glacial ...

Linking Soil Structure, Hydraulic Properties, and Organic Carbon Dynamics: A Holistic Framework to Study the Impact of Climate Change and Land Management

Sara Bonetti

Climate change and unsustainable land management practices have resulted in extensive soil degradation, including alteration of soil structure (i.e., aggregate and pore size distributions), loss of soil organic carbon, and reduction of water and nutrient h ...

Nonmycorrhizal root-colonizing fungi are key determinants of plant growth, driving processes ranging from pathogenesis to stress alleviation. Evidence suggests that they might also facilitate host access to soil nutrients in a mycorrhiza-like manner, but t ...

Using PhenoCams to track crop phenology and explain the effects of different cropping systems on yield

Christoph Bachofen, Yujie Liu

CONTEXT: Crop phenology integrates information of how environmental drivers and management practices affect plant performance and crop yield. However, little is known about the impact of cropping systems (CS) on crop phenology and how this relates to diffe ...

Legacy effect of green manure crops fertilized with calcium phosphite on maize production and soil properties

Alexandre Buttler, Luca Bragazza, Thomas Guillaume, Mathieu Raymond Santonja, Mario Fontana

Recycling phosphorus (P) is crucial to meet future P demand for crop production. We investigated the possibility to use calcium phosphite (Ca-Phi) waste, an industrial by-product, as P fertilizer following the oxidation of phosphite (Phi) to phosphate (Pi) ...
