Rare calcium chloride-rich soil and implications for the existence of liquid water in a hyperarid environment
(Geological Society of America, 2019)
We discovered permanently hydrated CaCl 2 -rich soils in Earth's driest region, the Atacama Desert. The soils contain up to ~15% CaCl 2 . X-ray diffraction indicates the rare minerals sinjarite, schoenite, and tachyhydrite. ...
Amazonian Anthrosols Support Similar Microbial Communities that Differ Distinctly from Those Extant in Adjacent, Unmodified Soils of the Same Mineralogy
(SPRINGER, 2010)
We compared the microbial community composition in soils from the Brazilian Amazon with two contrasting histories; anthrosols and their adjacent non-anthrosol soils of the same mineralogy. The anthrosols, also known as the ...

One of the marks left by prehistoric man in the Amazonas landscape are the dark-colored soil stains, Archeological Dark Earth (ADE), which are rich in organic matter, phosphorus and calcium. The color in this soil is ...
Sistemas de culturas em plantio direto adaptados à pequena propriedade relacionados com a erosão e atributos de um argissolo vermelho
(Universidade Federal de Santa MariaBREngenharia AgrícolaUFSMPrograma de Pós-Graduação em Engenharia Agrícola, 2009-11-16)
Considering soil management systems, are rare the research projects that are carried on by a time period long enough to several soil attributes may be expressed conveniently. The no-till system influences several soil ...
Soil changes in model tropical ecosystems: effects of stand longevity outweigh plant diversity and tree species identity in a fertile volcanic soil
(Springer, 2014-01)
Plant or community longevity can strongly influence soil fertility, yet it is seldom among the functional traits considered in studies of biodiversity and ecosystem functioning. For 11 years we tracked the influences of ...
