Interactions Between Dissolved Organic Carbon and Aluminium Activity in Tropical and Temperate No‐Till Agroecosystems

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
Conceptual model of depth‐stratified soil acidification under long‐term no‐till in temperate (Washington, USA) and tropical (Brazilian Oxisol) systems. Nitrogen inputs promote surface acidification (↓pH) and increased Al3+ activity, while lime or silicate amendments modify base cation dynamics. Increased DOC–Al complexation reduces free Al3+ and alters

Soil chemical properties effect on phosphorus fractions and maximum adsorption capacity in Brazilian tropical soils

Soil Science Society of America Journal, Volume 90, Issue 2, March/April 2026.
Abstract Phosphorus (P) availability in tropical soils is strongly limited by high adsorption capacity, primarily driven by mineralogical and chemical characteristics. This study aimed to evaluate the influence of soil properties on P sorption kinetics, maximum phosphorus adsorption capacity (MPAC), and P fraction distribution across 17 soil samples ...

Properties of iron oxides in some new caledonian oxisols

Geoderma, 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.

Influence of Fertilization on the Phytoremediation of Lead‐Contaminated Soils Using Tropical Grasses

Environmental Quality Management, Volume 35, Issue 3, Spring 2026.
ABSTRACT Lead is an element intensively used by human activities, representing serious risks to food security due to soil contamination, making it essential to implement control strategies to mitigate its harmful effects. The objective of this study was to evaluate the influence of soil fertilization on the growth and lead accumulation of grasses used ...

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

Soil 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.

Phenological description for the initial development stage of five Brazilian native forest species according to BBCH scale

Annals of Applied Biology, Volume 188, Issue 2, Page 561-581, March 2026.
Morphology of the two main growth stages—germination and initial development of the forest species Ceiba speciosa (co, cotyledon; eo, eophyll; hp, hypocotyl; me, metaphyll; pk, prickles; pr, primary root; se, seed; sr, secondary root). Abstract A specific phenological scale designated for each forest species facilitates the standardization of different

Functional Redundancy Buffers Soil Fungal Turnover Against Vegetation Change in an African Savanna

Biotropica, Volume 58, Issue 2, March 2026.
Using a natural savanna‐forest gradient in South Africa, we show that vegetation transitions drive high turnover in fungal taxonomy but maintain functional stability. Distinct forest communities replaced savanna taxa yet preserved similar guild structures, highlighting a high degree of functional redundancy despite compositional change.
