Phytoremediation of soils contaminated by organic compounds: hype, hope and facts

Jean-Paul Schwitzguebel

The present opinion paper is focused on the phytoremediation of organic pollutants and is based on the lectures given by the author during the International Congress of Phytoremediation of Polluted Soils, held at Vigo, Spain, 29-30 July 2014. The aim of th ...

Tropical soils degraded by slash-and-burn cultivation can be recultivated when amended with ashes and compost

Alexandre Buttler, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek, Robert Thomas Edmund Mills, Justine Marie Gay des Combes

In many tropical regions, slash-and-burn agriculture is considered as a driver of deforestation; the forest is converted into agricultural land by cutting and burning the trees. However, the fields are abandoned after few years because of yield decrease an ...

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 ...

Anthropogenic charcoal-rich soils of the XIX century reveal that biochar leads to enhanced fertility and fodder quality of alpine grasslands

Soil incorporation of charcoal (biochar) has been suggested as practice to sequester carbon, improve soil properties and crop yields but most studies have been done in the short term. Old anthropogenic charcoal-rich soils in the Alps enable to explore the ...

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 ...

Climate change effects on the stability and chemistry of soil organic carbon pools in a subalpine grassland

Alexandre Buttler, Bjorn Jozef Maria Robroek, Konstantin Svetlozarov Gavazov, Robert Thomas Edmund Mills, Thomas Spiegelberger

Mountain soils stock large quantities of carbon as particulate organic matter that may be highly vulnerable to climate change. To explore potential shifts in soil organic matter (SOM) form and stability under climate change (warming and reduced precipitati ...
