A Stochastic Approach to Quantifying the Propagation of Uncertainty in Soil Organic Carbon Content

open access: yesJournal of Plant Nutrition and Soil Science, Volume 189, Issue 1, Page 117-130, February 2026.
ABSTRACT Background Precision agriculture (PA) is a site‐specific management approach that utilises spatiotemporal information to improve productivity while also promoting sustainability. Accurate estimates of soil properties, along with the uncertainty of these estimates, are necessary for decision‐making in PA.

Influences of Sampling Design and Model Selection on Predictions of Chemical Compounds in Petroferric Formations in the Brazilian Amazon

open access: yesRemote Sensing
Morro de Seis Lagos, a region in the Brazilian Amazon, contains a small (less than 1%) formation of siderite carbonatites which is considered to be one of the world’s largest niobium reserves.

A pedogeomorphic strategy for tidal marsh carbon accounting

open access: yesSoil Science Society of America Journal, Volume 90, Issue 1, January/February 2026.
Abstract Tidal marsh soils have some of the largest carbon stocks of any ecosystem, yet uncertainty remains about the best approach to quantify these C stocks. We tested whether separating tidal marshes into pedogeomorphic units (PGUs) could improve regional‐scale blue C accounting in two separate regions on the Atlantic coast: southern New England (NE)

Complementary geophysical, geomorphometric and pedological approaches for characterizing shallow and deep subsurface materials in a colluvial‐alluvial plain in Atlantic rainforest

open access: yesEarth Surface Processes and Landforms, Volume 50, Issue 15, December 2025.
This study combines GPR, 2D ERT and UAV‐derived terrain models to characterize sediment variability in a colluvial‐alluvial plain. GPR identified sandy lenses and clay‐rich layers, while ERT revealed deeper conductive and resistive zones, including a gneissic basement.

Pedometric mapping for soil fertility management – A case study

open access: yesJournal of the Saudi Society of Agricultural Sciences, 2021
Information about soil physico-chemical parameters plays an important role in precision farming. To examine the relationship among soil properties, pedometric mapping is essential and has been widely applied in agricultural activities. This paper is aimed at soil nutrient assessment by generating the geospatial distribution maps for Kestur, a village ...

Adjusting Bulk Density Observations in the Hungarian Soil Information and Monitoring System Using Pedotransfer Functions

open access: yesEuropean Journal of Soil Science, Volume 76, Issue 6, November–December 2025.
ABSTRACT Bulk density (BD) is among the most important physical soil properties, influencing many other soil properties, functions and services. An earlier study revealed that BD observations in the Hungarian Soil Information and Monitoring System (SIMS) contain errors and need correction.

Soil legacy data: An opportunity for digital soil mapping [PDF]

open access: yesRevista Brasileira de Ciência do Solo
Soil legacy data is past information on soils available from various sources (e.g. survey reports and maps). When compiled and organized, data obtained through historical retrieval can be used as basic input or validation data for digital soil mapping. A
