Valorization of calcium phosphite waste as phosphorus fertilizer: Effects on green manure productivity and soil properties

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

The potential to use calcium phosphite (Ca-Phi) as phosphorus (P) fertilizer may represent an effective recycling of P-containing by-products. A greenhouse experiment was conducted to investigate the effect of Ca-Phi (38 kg P ha(-1)) on soil properties and ...

Robust and sustainable cultivation of microalgae: recycling of nitrogen from liquid digestate and control of biological contamination

Adrian Pulgarin

The present doctoral thesis aimed to achieve a robust cultivation of microalgae by recycling nitrogen from a liquid digestate. However, the use of non-sterile nutrient source increases the risks of contamination of undesired organisms such as bacteria, vir ...

High summer temperatures amplify functional differences between coral‐ and algae‐dominated reef communities

Nils Rädecker, Hal Hunt Jones II

Shifts from coral to algal dominance are expected to increase in tropical coral reefs as a result of anthropogenic disturbances. The consequences for key ecosystem functions such as primary productivity, calcification, and nutrient recycling are poorly und ...

Big dairy data to unravel effects of environmental, physiological and morphological factors on milk production of mountain-pastured Braunvieh cows

Stéphane Joost, Elia Vajana, Solange Catherine Gaillard

The transhumance system, which consists in moving animals to high mountain pastures during summer, plays a considerable role in preserving both local biodiversity and traditions, as well as protecting against natural hazard. In cows, particularly, milk pro ...

Alternative Scenarios for the Development of Oil Palm in the Tropics: Carbon and Nutrients Dynamics

Juan Carlos Quezada Rivera

Expansion of agriculture in forested areas poses significant threats and pressure to ecosystems and potentially the global climate. More specifically, expansion of oil palm (OP) plantations has been found to exert great impact on key ecosystem functions li ...

Nutrients influence seasonal metabolic patterns and total productivity of Arctic streams

Luis Gómez Gener

The seasonality of gross primary production (GPP) in streams is driven by multiple physical and chemical factors, yet incident light is often thought to be most important. In Arctic tundra streams, however, light is available in saturating amounts througho ...

Long-term effects of crop succession, soil tillage and climate on wheat yield and soil properties

Mathieu Raymond Santonja, María Paula Sanginés De Cárcer

Climate change is increasing crop losses and yield variability with impacts for global food security. In this context, conservation agriculture appears as a potential solution to maintain crop productivity, soil fertility and environmental sustainability. ...

GeoFarmer: A monitoring and feedback system for agricultural development projects

Claudia Rebeca Binder Signer

Farmers can manage their crops and farms better if they can communicate their experiences, both positive and negative, with each other and with experts. Digital agriculture using internet communication technology (ICT) may facilitate the sharing of experie ...

Smart Factory Information Service Bus (SIBUS) for manufacturing application: requirement, architecture and implementation

Ian Anthony Stroud, Jumyung Um

The Smart Factory is an important topic worldwide as a means for achieving Industry 4.0 in the manufacturing domain. Contemporary research on the Smart Factory has been concerned with application of the so-called Internet of Things (IoT) to the shop floor. ...

Cost and benefits of climate change in Switzerland

Philippe Thalmann, Marc Vielle, Frank Vöhringer, Boris Thurm, Dario Stocker, Wolfgang Knoke, Anita Frehner

Understanding the economic magnitude of climate change impacts is a prerequisite for developing adequate adaptation strategies. In Switzerland, despite new climate scenarios and impact studies, only few impacts have been monetized. Our objective is to asse ...

Transpiration on the rebound in lowland Sumatra

Mitsunori Nomura, Thomas Guillaume

Following large-scale conversion of rainforest, rubber and oil palm plantations dominate lowland Sumatra (Indonesia) and other parts of South East Asia today, with potentially far-reaching ecohydrological consequences. We assessed how such land-use change ...

Responses of permanent grasslands to drought during the plant growing season: combining agronomic, functional and ecophysiological approaches

Amarante Vitra

Extreme summer drought events are predicted to increase in intensity and frequency within the current century. The resulting water scarcity could dramatically impact human activities related to agriculture, due to the strong relationship between precipitat ...

Time-Continuous Phosphorus Flows in the Indian Agri-Food Sector: Long-Term Drivers and Management Options

Claudia Rebeca Binder Signer

Phosphorus (P) is a major agricultural nutrient and, in its mineable form, a potentially scarce resource. Countries with limited physical access to P should hence develop an effective national P governance. This requires analyses of trends and variations i ...

Land-use change affects phosphorus fractions in highly weathered tropical soils

Thomas Guillaume

Deforestation and land-use change in tropics have increased over the past decades, driven by the demand for agricultural products. Although phosphorus (P) is one of the main limiting nutrients for agricultural productivity in the tropics, the effect of lan ...

Evaporation from cultivated and semi-wild Sudanian Savanna in west Africa

Marc Parlange, Natalie Claire Ceperley, Theophile Mande, Nicolaas Cornelis van de Giesen

Rain-fed farming is the primary livelihood of semi-arid west Africa. Changes in land cover have the potential to affect precipitation, the critical resource for production. Turbulent flux measurements from two eddy-covariance towers and additional observat ...

Effects of flooding on phosphorus and iron mobilization in highly weathered soils under different land-use types: Short-term effects and mechanisms

Thomas Guillaume

The strong affinity of phosphorus (P) to iron (Fe) oxides and hydroxides in highly weathered tropical soils limits P availability and therefore plant productivity in tropics. In flooded soils, however, P fixed by Fe oxides and hydroxides can be released in ...

Common reef-building coral in the Northern Red Sea resistant to elevated temperature and acidification

Anders Meibom, Stéphane Laurent Escrig, Thomas Krüger, Maoz Fine, Julia Marie Jeanne Yvonne Bodin, Maria-Evangelia Giovani

Coral reefs are currently experiencing substantial ecological impoverishment as a result of anthropogenic stressors, and the majority of reefs are facing immediate risk. Increasing ocean surface temperatures induce frequent coral mass bleaching events—the ...
