Actinobacteria Structure in Autogenic, Hydrogenic and Lithogenic Cultivated and Non-Cultivated Soils: A Culture-Independent Approach

open access: yesAgronomy, 2019
The aim of the study was to determine the Actinobacteria structure in cultivated (C) versus non-cultivated (NC) soils divided into three groups (autogenic, hydrogenic, lithogenic) with consideration its formation process in order to assess the ...

Using [delta] ph as a geochemical index of illite neoformation in saprolite [PDF]

open access: yes, 2008
Sal pH is routinely measured for agronomic purposes. When the difference between KCI pH and H2O pH, or ApH, yields positive values, it is used by soil scientists as a classification criterion for identifying anionic subgroups according to the Soil ...

The double modal construction in English world wide

open access: yesWorld Englishes, EarlyView.
Abstract The dual foci of the present study of double modals are their semantic characteristics and their distribution across regional varieties of English world wide. Tokens were extracted from GloWbE:Blogs, a database whose great size and informal tenor facilitated the investigation of this low‐frequency non‐standard feature. Double modals were found

Degradation and Restoration of Anthrosols in the Amazonia Under Contrasting Agricultural Practices: Evidence From the Assessment of Soil Physical Quality and Carbon and Nitrogen Stocks

open access: yesJournal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT This study was conducted to assess the impact of different agricultural practices on the physical quality and the carbon and nitrogen stocks of anthropogenic soils used by smallholder farmers in Central Amazonia, Brazil. Undisturbed and disturbed soil samples were collected at three depths (0–0.10 m, 0.10–0.20 m, and 0.20–0.30 m), with five ...
