Using a Portuguese regosol to derive soil reference values for arsenic

Revista de Ciências Agrárias, 2022
Abstract Soil reference values (SRV) are preliminary screening benchmark values used to evaluate the potential toxicity of specific contaminants in soils. The Portuguese Environmental Agency has proposed SRV for metals and metalloids based on soil uses but without consideration for the soil type. This project aims to derive SRV for arsenic (As) using a

Vegetación arbórea de selvas bajas caducifolias en suelos litosoles y regosoles eutricos degradados

REVISTA TERRA LATINOAMERICANA, 2020
En México, las selvas bajas caducifolias (SBC) son perturbadas por actividades agrícolas. Su regeneración origina el restablecimiento de vegetación arbórea secundaria que, con menor cobertura vegetal y arraigo, produce suelos termófilos e hidrófobos vulnerables a la erosión, que impiden la regeneración de SBC.

Variability of morphological, physical and chemical properties of soils derived from carbonate-rich parent material in the Pieniny Mountains (south Poland)

Soil Science Annual, 2017
Carbonate-rich soils are characterized by great diversity in content of carbonate and non-carbonate mineral substances in soil substrate which largely influences soil properties.

Grazing and climate interact to regulate greening trends in Mediterranean grasslands

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.
Our results show that traditional grazing systems can maintain grassland stability without causing degradation, but they can also increase the ecosystem's vulnerability to climate change. We provide clear evidence that GPS‐based livestock monitoring is a powerful and scalable tool for sustainable rangeland management.

The Restoration Debt Remains: Topsoil Removal and Different Mowing Regimes Reach Desired States of Calcareous Grassland but Do Not Match the Reference

Applied Vegetation Science, Volume 29, Issue 1, January/March 2026.
Restoration of calcareous grasslands on former arable land was evaluated using a long‐term experiment with topsoil removal and different mowing regimes. Vegetation surveys showed that neither approach reproduced old‐growth reference sites. Topsoil removal and mowing produced distinct species and trait assemblages, while mowing timing was irrelevant ...

Influence Mechanisms of Rainfall and Terrain Characteristics on Total Nitrogen Losses from Regosol [PDF]

Water, 2017
The upper reach of the Yangtze River is an ecologically sensitive region where water loss, soil erosion, and nonpoint source (NPS) pollution are serious issues. In this drainage area, regosol is the most widely distributed soil type. Cultivation on regosol is extensive and total nitrogen (TN) has become a common NPS pollutant.

Water and Dissolved Carbon Fluxes in an Eroding Soil Landscape Depending on Terrain Position

Vadose Zone Journal, 2014
Leaching of dissolved C in arable hummocky ground moraine soil landscapes is characterized by a spatial continuum of more or less erosion‐affected Luvisols, Calcaric Regosols at exposed positions, and Colluvic Regosols in depressions.

RELATING LOSS OF SOIL FERTILITY TO WATER AGGREGATE STABILITY AND NUTRIENT AVAILABILITY IN MOUNTAIN AGRICULTURAL CALCARIC SOILS

EQA, 2014
We investigated the topsoil from some mountain Regosols for their nutrient status and loss of fertility due to aggregate breakdown, establishing also the relationship between the nutrient losses, the soil characteristics and the aggregates stability. The

Effect of Regenerative Agriculture on Soil Health, Ecosystem Services and Economic Performance in a Commercial Olive Orchard in Southern Spain

Soil Use and Management, Volume 42, Issue 1, January‐March 2026.
ABSTRACT Regenerative agriculture (Reg) improves soil health, ecosystem services and economic performance, but its impact on olive groves remains underexplored. This study evaluates soil physical, chemical and biological properties, ecosystem services and economic outcomes in adjacent regenerative (Reg) and conventional (Conv) olive groves in southern ...
