Applying multivariate methods to soil–solution interactions in carbonate media

Assessing spatial variability in soil characteristics with geographically weighted principal components analysis

“…The observed relationships from the PCA analysis suggest that there exists an intricate connection among the various soil parameters across the entire state which can be difficult to observe physically. PCA has been used extensively by numerous researchers to: (i) study the factors that control the chemical properties of organic soil solutions [38], (ii) investigate how the chemical properties of slightly to moderate saline calcareous soil solutions change with time [32], (iii) assess how the parent material affects the chemical properties of soil solutions derived from calcareous and siliceous rocks [40], and (iv) evaluate how soil solids affect the chemical properties of soil leachates [12]. However, PCA has the limitation that the results obtained from this analysis are unable to explain the local spatial variations [21].…”

“…Na Sodium (meq/100 g) 10 K Potassium (K + ; meq/100 g) 11 EXACID Extractable acidity (meq/100 g) 12 BS Base saturation (%) are implications in that at least one covariance and, thus, correlation coefficient must be negative. In such a case, none of the correlation coefficients is free to range from −1 and +1.…”

Application of various methodological approaches for assessment of soil micromorphology due to VESTA program applicable to prediction of the soil structures formation

“…abs. intensity/ volume **2: 23.23709141 glycol solvation (González et al, 2007). Šucha et al (1993) as the first step samples have to be pulverized in agate mortal under 0.2 mm followed by ultrasonic probe disintegration.…”

“…from various type of matrices (Čurlík, 2011;Čurlík and Kolesár, 2014;Markgraf and Reeder, 1985;González et al, 2007). The X-ray analysis (beam of rays) belongs to part of electromagnetic spectra which be generated by the swift movement braking with fast flux electrons on the physical barrier.…”

Quantifying the crop management influence on arable soil condition in the Inland Pampa (Argentina)

“…However, few works have used multivariate analysis in addition to univariate analysis to study soil parameters (Gonzalez et al, 2007). The aim of this study is to introduce a novel approach to explore the nature of the relationship between a group of crop management factors and a response matrix of the soil properties.…”
