ABSTRACT Soil organic carbon (SOC) plays a critical role in key soil functions, yet SOC is highly vulnerable to human activities, which can shift from acting as net sink becoming source. Despite considerable efforts monitor conditions, traditional evaluations often focus on temporal comparisons within similar locations, limit the understanding of broader changes. To address these challenges, this study employs pedogenon map framework systematically compare changes soils under natural conditions (genosoils) and those affected by activity (phenosoils) across Australia. By analysing fractions with different mean residence times – mineral‐associated (MAOC) particulate (POC) aims assess durability over time. The methodology includes selecting profiles pedogenons, evaluating changes, estimating impact SOC's time using tonne‐year (STYC) metric. findings reveal significant spatial variations their Areas where increased are mainly due genosoils lower values, while high values have significantly decreased when converted phenosoils, reflecting potentially unsustainable agricultural practices. Similar results been found concerning regarding values. demonstrates that an effective tool for detecting providing robust assessing storage informing targeted remediation strategies.

Abstract This study analyses the soil organic carbon to clay (SOC/clay) ratio, bulk density ( ρ B ) and packing P related some basic variables, classes types, land uses of various environments, assess recommendations made by European Commission (2023). Soil profiles from representative landforms, climate soils were analysed, properties processed. In cropland soils, which found be least healthy because both lower SOC/clay higher , values 1/13 should a target, not only for loamy clayey textures but also neutral pH alkaline soils. The ratio 1/10 target grassland soils; forest that generally presented highest ratios (the healthiest soils), there is no such recommendation. produced unexpected results within characterizing low‐fertile (Psamosols) as healthy, well‐structured rich‐in‐SOC (Chernozems, Phaeozems) unhealthy. Consequently, need improve this combining it with other properties, example, texture. recommended (2023, Annexes) are too high Romanian would encourage compaction. proposed start penalizing crops' yields 1.77 kg/dm 3 sandy, 1.73 loamy‐sandy, 1.67 sandy‐loamy, 1.63 loamy, 1.56 clayey‐loamy texture 1.44 Using adequate methods increase SOC, will improved.

Classification of remote sensing images using machine learning models requires a large amount training data. Collecting this data is both labor-intensive and time-consuming. In study, the effectiveness pre-existing reference on land cover gathered as part Land Use–Land Cover Area Frame Survey (LUCAS) database Copernicus program was analyzed. The classification carried out in Google Earth Engine (GEE) Sentinel-2 that were specially prepared to account for phenological development plants. performed SVM, RF, CART algorithms GEE, with an in-depth accuracy analysis conducted custom tool. Attention given reliability different metrics, particular focus widely used (ML) metric “accuracy”, which should not be compared commonly “overall accuracy”, due potential significant artificial inflation accuracy. LUCAS 2018 at Level-1 detail estimated 86%. Using updated dataset, best result achieved RF method, 83%. An overestimation approximately 10% observed when reporting average ACC ML instead overall OA metric.
