Chernozem. From concept to classification: a review

Acta Universitatis Carolinae Geographica, 2016
In this paper, we put together the most important facts that lead to the research on chernozem. Thanks to the work of V. V. Dokuchaev (1846–1903), chernozem stands at the forefront of pedology. In 1883, Dokuchaev introduced the first concept of chernozem:

Rangitīkei River Terraces Formed During the Otira Glaciation: Lithostratigraphic Type Sections, Review and Conceptual Model

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
The Rangitīkei Valley in the lower North Island of New Zealand contains flights of river terraces that are influenced by changes in sediment supply, stream power and base level associated with Quaternary climate events over the last ∼350 thousand years.

Gonadal Development in Larvae of the Paedomorphic Ambystoma mexicanum (Amphibia: Urodela)

Journal of Morphology, Volume 287, Issue 3, March 2026.
This research analyzes the gonads of Ambystoma mexicanum larvae of both sexes, revealing significant changes such as the onset of vitellogenesis in females at 9 months of age and oocytes with signs of maturity at 12 months. In males, gonadal maturity occurs earlier, with a notable cephalocaudal and lateromedial testicular regionalization, and ...

Cold desert soil formation in Heritage Range, Ellsworth Mountains, West Antarctica [PDF]

Anais da Academia Brasileira de Ciências
The Ellsworth Mountains represent a significant gap in pedological studies in Antarctica, particularly concerning soil formation at the local level. This study focused on 22 soil profiles from the southern portion of the Ellsworth Mountains, developed on

Soil carbon, nitrogen, and biological activity as affected by land use and grassland management across North Carolina

Soil Science Society of America Journal, Volume 90, Issue 2, March/April 2026.
Abstract Undisturbed land uses have the potential to enhance soil organic matter, but how and to what extent this occurs on private farms remains relatively unexplored. A cross‐sectional study of perennial grasslands and farm woodlots was undertaken across North Carolina to investigate stocks of soil organic C, total soil N, and soil‐test biological ...

Effects of land-use change on morphological, physicochemical, and mineralogical properties of volcanic soils in southern Chile

Geoderma
Chilean volcanic soils, such as Andisols and Ultisols, cover much of the country’s arable land and are valued for their unique mineralogical characteristics.

Defining soil: Proposals of zero‐states, active layer, and págousols (from ice parent materials) to fundamentally expand soil science

Soil Science Society of America Journal, Volume 90, Issue 2, March/April 2026.
Abstract Recent publications in soil science have reopened discussions over how soil and soil science should be defined, reflecting productive tension between historical constructs and the evolving frontiers of the discipline. While new definitions offered over the past decade provide valuable perspectives, they inevitably rely on past conventions and ...

Microtopography controls organic and inorganic carbon stocks in Vertisols: Insights from a climosequence on the Texas coastal plain

Soil Science Society of America Journal, Volume 90, Issue 2, March/April 2026.
Abstract Complex interactions between ecological and environmental factors govern soil organic carbon (SOC) and soil inorganic carbon (SIC) stocks across landscapes. In gilgai‐bearing Vertisols, submeter differences in water availability result in micro‐spatial variability in soil properties.
