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.

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.

Full‐pattern fitting of X‐ray powder diffraction data to determine allophane and organic matter contents in soils

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract Full‐pattern fitting of X‐ray powder diffraction (XRPD) data using reference materials has attracted increasing attention as a high‐throughput method to determine the contents of long‐range‐ordered (i.e., crystalline) materials in soils. We hypothesized that this XRPD method can also be used to quantify short‐range‐ordered (SRO) materials with

Understanding cation exchange capacity through the landscape lens of the Busoga Catena, Uganda

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract This study identifies the parent material (PM) and examines cation exchange capacity (CEC) across the Busoga catena. In 2022 and 2023, we described 32 pedons and collected 147 samples. Laboratory analyses were particle size analysis, organic carbon (OC) content, pH, and CEC.

Non-legume plant species effects on soil nematodes abundance in a Regosol

Agropecuária Técnica, 2019
The effects of a non-legume cover crop on total soil nematode abundance and soil groups of nematodes were investigated in a long-term field study. We compared total abundance of soil nematode and the abundance of both free-living soil nematode and root-feeding soil nematode under three different treatments (Pennisetum glaucum (L.) R.

Digital soil mapping from conventional field soil observations

Soil and Water Research, 2013
We tested the performance of a formalized digital soil mapping (DSM) approach comprising fuzzy k-means (FKM) classification and regression-kriging to produce soil type maps from a fine-scale soil observation network in Rišňovce, Slovakia.

Pedotransfer functions for estimating the maximum bulk density of major Brazilian agricultural soils: Model comparison and validation

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract The Proctor compaction test is the standard method for determining the maximum bulk density (Dbmax) of a soil, a key parameter for obtaining the degree of compaction. However, this method is labor‐intensive and time‐consuming, making it impractical for routine soil quality assessment.

Diversität von Ektomykorrhizapilzen unter Pioniervegetation auf einem küstennahen Regosol

, 2011
Die natürliche Pioniervegetation auf küstennahen Regosolen in Norddeutschland umfasst mehrere Wirtspflanzen von Ektomykorrhizapilzen, wie z.B. Salix, Populus und Pinus spp.. Ektomykorrhizapilze können auf diesen stark erosionsgefährdeten Standorten durch die Ausbildung von abziehenden Hyphen bzw. Rhizomorphen zur Stabilisierung der Oberböden beitragen.
