The kaolinite-group minerals kaolinite, dickite, nacrite, halloysite including its metaform and
their associates allophane and imogolite are phyllosilicates characterized by a rather simple …

This study focuses on the dating of millimetric pisoliths from ferruginous duricrusts located in
central Amazonia (Brazil), by coupling detailed mineralogy and two relevant dating …

Although cosmic‐ray neutron sensing (CRNS) is probably the most promising noninvasive
proximal soil moisture measurement technique at the field scale, its application for …

Ferralsols and Acrisols are major types of soils of the Amazon basin observed on various
landform units comprising plateau surfaces, incised hills at their edges and slopes. The …

Over a billion tons of terrestrial carbon (C) is stored in deep soils from the Southeastern
Coastal Plain of the United States. While the size and extent of this pool, known as deep …

The Amazon rainforest presents one of the greater biodiversity in the world and a huge and
dynamic carbon reservoir, both in the vegetation and in the soil pools, so it is an attractive …

Soil carbon decomposition is primarily driven by microbial activities and is regulated by
factors which stimulate or impede microbial functions. Deep podzolized carbon (DPC), found …

Podzol soils are an important carbon pool in the Amazon, due to the high organic matter
(OM) content in their topsoil horizons and deep Bh. To quantify the evolution of the stock and …

Structural defects of kaolinite could be associated with its genetic (weathering, pedogenetic,
and hydrothermal) processes. Kaolinite crystallinity indices were evaluated in the context of …

Transfer of organic carbon from topsoil horizons to deeper horizons and to water table is still
little documented, in particular in equatorial environments despite the high primary …
