Knowing the taxonomy, mineralogy, and properties of soils is essential to understand their genesis, functionality, and potential use, and it is fundamental for implementing land-use planning and to characterize soil use management systems. The objective of this study was to describe and correlate the taxonomic characteristics (Soil Taxonomy and World Soil Classification), morphological, physicochemical, and mineralogical characteristics of soils in relation to their physiographic position, based on 15 profiles of a toposequence obtaining 81 horizons. It was verified that soil variability was linked to relief; likewise, soil orders ranging from Entisols to Inceptisols were identified according to the Soil Taxonomy classification. While through the World Soil classification, the groups: Fluvisols, Regosols, Umbrisols, Cambisols, and Luvisols were identified. Morphologically, the fluvial so...

Identifying the carbon isotopic ratio is valuable for analyzing and understanding soil classification and dynamics. This study evaluated and related the soil isotopic ratio and its main properties (physicochemical) in the Monzón Valley. Fifteen pits were sampled within the strata of a toposequence. δ13C was determined using an isotope ratio mass spectrometry system coupled with an EA-IRMS elemental analyzer. To obtain accurate results, samples were categorized based on their depth. Between 500 and 600 µg of soil were weighed for samples <40 cm deep, and between 1500 and 2000 µg for samples deeper than 40 cm. The results provided information on the stable carbon content of the soil, separating each sample by its soil profile, depth, pH, color, Al, cultivar, carbon stock, taxonomic classification, among others. Differences in properties were found among the profiles studied, with qu...
