Decrease in carbon stocks in an oxisol due to land use and cover change in southwestern Amazon. [PDF]

open access: yes, 2019
This study presents data on the influence of the land cover type on soil carbon stocks in an Oxisol in southwestern Amazon, Acre, Brazil, under three land cover types: mature forest, pasture and rubber tree plantation.

High‐Resolution Soil Total Phosphorus Mapping for the Conterminous USA Using Machine Learning

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 1, January 2026.
Abstract Accurate estimates of soil total phosphorus (TP) concentrations are essential for sustainable nutrient management, food security, and water quality protection. This study predicts and maps the spatial distribution of TP in the top 5 cm and C horizon of soils across the conterminous USA (CONUS) using data from the Geochemical and Mineralogical ...

Biological P cycling is influenced by the form of P fertilizer in an Oxisol

open access: yesBiology and Fertility of Soils, 2017
Phosphate rock (PR) is an alternative fertilizer to increase the P content of P-deficient weathered soils. We evaluated the effects of fertilizer form on indicators of biological cycling of P using an on-farm trial on a Rhodic Kandiudox in western Kenya.

Biogeochemical asymmetry and the diversification of tropical rain forests in Borneo: The endmember hypothesis

open access: yesFunctional Ecology, Volume 40, Issue 1, Page 4-14, January 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Mixed dipterocarp lowland tropical rain forests on Oxisols and Ultisols and heath forests on Spodosols are considered distinct vegetation types in Borneo. Here we present the endmember hypothesis of ecosystem diversification, which describes a continuum of forest ...

Charge characteristics in relation to mineralogy of selected soils from South-east Asia [PDF]

open access: yes, 1996
The mineralogy and charge characteristics of 7 soils from the Philippines, Indonesia and Malaysia were studied. The soils consisted of an Entisol, 3 Alfisols, an Andisol and 2 Oxisols.

Properties of iron oxides in some new caledonian oxisols

open access: yesGeoderma, 1986
Abstract Oxisols from two toposequences of New Caledonia formed from peridotite, consist essentially of Fe oxides (goethite, hematite, maghemite). These Fe oxides were characterized by their mineralogy, crystal size and morphology, Al substitution, thermal behaviour and dissolution kinetics in 6 M HCl at 25°C.

Biochar: A Sustainable Solution for Mitigating Greenhouse Gas Emissions and Enhancing Soil Productivity—A Review

open access: yesScientifica, Volume 2026, Issue 1, 2026.
Greenhouse gases (GHGs) resulting from human activities significantly impact crop production and agricultural sustainability, necessitating innovative solutions to mitigate their effects. One promising approach is employing biochar for GHG mitigation, providing a potential means to offset emissions and enhance crop productivity sustainably.

Nickel Effects on Growth and Phytolith Yield of Grasses in Contaminated Soils

open access: yesSoil Systems
Nickel (Ni) is extremely toxic to plants at high concentrations. Phytoliths have the potential to sequester the heavy metals absorbed by plants and act as a detoxification mechanism for the plant.
