Accumulation of century-old biochar contributes to carbon storage and stabilization in the subsoil

Autor: Julien Fouché, Victor Burgeon, Jeroen Meersmans, Jens Leifeld, Jean-Thomas Cornelis

Publikováno v: Geoderma, Vol 440, Iss , Pp 116717- (2023)

Soil organic carbon (C) is a key component of the global C budget. As soil organic C turnover rates decrease with depth, agricultural practices favoring deep organic C storage will gain importance as long-term climate change mitigation strategies. In

Permafrost degradation may lead to mobilization of carbon and nutrients and enhance microbial processing rates of previously frozen organic matter. Although the pool size and chemical composition of dissolved organic matter (DOM) are fundamental dete

Nutrient cycling differs between cropped soils with century-old and recently pyrolyzed biochar

Autor: Sarah Garré, Gilles Colinet, Julien Fouché, Ramin Heidarian-Dehkordi, Jean-Thomas Cornélis, Victor Burgeon

The amendment of biochar to soils is often considered for its potential as a climate change mitigation and adaptation tool through agriculture. Its presence in tropical agroecosystems has been reported to positively impact soil productivity whilst su

The SPLASH Action Group – Towards standardized sampling strategies along the soil-to-hydrosystems continuum in permafrost landscapes

Autor: Yannick Agnan, Lisa Bröder, Sarah Shakil, Julien Fouché, Frédéric Bouchard, Catherine Hirst, Ylva Sjöberg

The Action Group called ‘Standardized methods across Permafrost Landscapes: from Arctic Soils to Hydrosystems’ (SPLASH), funded by the International Permafrost Association, is a community-driven effort aiming to provide a suite of standardized fi

Ongoing warming of the Northern high latitudes has intensified abrupt thaw processes throughout the permafrost zone. The resulting terrain disturbances are prone to release large amounts of particulate organic matter (OM) from deeper permafrost soils
