Interaction of compost additives with phosphate solubilizing rhizobacteria improved maize production and soil biochemical properties under dryland agriculture

Alexandre Buttler, Luca Bragazza, Bjorn Jozef Maria Robroek, Muhammad Saleem Arif, Muhammad Riaz, Muhammad Ashraf

Dry land soils from the Indo-Gangetic plains are inherently poor in organic matter content and phosphorus (P). Amendment of these soils with P-enriched compost, together with P solubilizing rhizobacterial (PSR) inoculation has been suggested to improve pla ...

Nitrogen-enriched compost application combined with plant growth-promoting rhizobacteria (PGPR) improves seed quality and nutrient use efficiency of sunflower

Alexandre Buttler, Luca Bragazza, Muhammad Saleem Arif, Muhammad Riaz

Ecological benefits associated with plant growth-promoting rhizobacteria (PGPR) inoculants offer a promising integrated nutrient management option to counteract plant nitrogen (N) deficiency. We performed field experiments to evaluate the effect of integra ...

Taxonomic and functional turnover are decoupled in European peat bogs

Alexandre Buttler, Luca Bragazza, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek

In peatland ecosystems, plant communities mediate a globally significant carbon store. The effects of global environmental change on plant assemblages are expected to be a factor in determining how ecosystem functions such as carbon uptake will respond. Us ...

Peatland vascular plant functional types affect dissolved organic matter chemistry

Alexandre Buttler, Luca Bragazza, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek, Adrian Pulgarin, Remy Jean Henry Albrecht, Samuel Thomas Gabriel Hamard

Northern peatlands are large repositories of carbon. Peatland vascular plant community composition has been functionally associated to a set of biogeochemical processes such as carbon cycling. Yet, we do not fully understand to what extent vascular plant f ...

Responses of soil properties and crop yields to different inorganic and organic amendments in a Swiss conventional farming system

Konstantin Svetlozarov Gavazov, Luca Bragazza, Guillaume Blanchet

In agro-ecosystems, fertilization practices are crucial for sustaining crop productivity. Here, based on a 50-year long-term experiment, we studied the influence of fertilization practices (inorganic and/or organic) and nitrogen (N) application rates on (i ...

Persistent high temperature and low precipitation reduce peat carbon accumulation

Alexandre Buttler, Luca Bragazza, Vincent Eric Jules Jassey, Constant Signarbieux, Bjorn Jozef Maria Robroek, Remy Jean Henry Albrecht

Extreme climate events are predicted to become more frequent and intense. Their ecological impacts, particularly on carbon cycling, can differ in relation to ecosystem sensitivity. Peatlands, being characterized by peat accumulation under waterlogged condi ...

Associative interplay of plant growth promoting rhizobacteria (Pseudomonas aeruginosa QS40) with nitrogen fertilizers improves sunflower (Helianthus annuus L.) productivity and fertility of aridisol

Alexandre Buttler, Luca Bragazza, Vincent Eric Jules Jassey, Muhammad Saleem Arif, Muhammad Riaz

The environmental and economic impacts of chemical fertilizer have encouraged farmers to integrate them with organic materials, an important nutrient management strategy for sustainable agriculture production. In the present study, we conducted field exper ...

Environmental drivers of carbon and nitrogen isotopic signatures in peatland vascular plants along an altitude gradient

Alexandre Buttler, Konstantin Svetlozarov Gavazov, Luca Bragazza

Peatlands are important sinks of atmospheric carbon (C) that, in response to climate warming, are undergoing dynamic vegetation succession. Here we examined the hypothesis that the uptake of nutrients by different plant growth forms (PGFs) is one key mecha ...

Loss of testate amoeba functional diversity with increasing frost intensity across a continental gradient reduces microbial activity in peatlands

Alexandre Buttler, Luca Bragazza, Vincent Eric Jules Jassey, Mariusz Lamentowicz, Constant Signarbieux, Bjorn Jozef Maria Robroek, Robert Thomas Edmund Mills, Maaike Louise Hofsommer

Soil microbial communities significantly contribute to global fluxes of nutrients and carbon. Their response to climate change, including winter warming, is expected to modify these processes through direct effects on microbial functions due to osmotic str ...
