In this investigation, we consider different architectures of the dispersion and clustering of soil macropore space as deviations from the linear pattern of log-log lacunarity functions.
Cluster analysis of soil characteristics revealed 3 clusters, one of which including Hg species.
Cluster analysis of soil characteristics has confirmed the hypothesis of the anthropogenic origin of Hg in the area contaminated by the chlor-alkali industry by grouping Hg species in the same cluster, distinct from that including natural components of soil such as aluminosilicates.
Cluster and factor analyses of soil chemical and physical parameters confirm the redistribution of local sediments as a dominant factor behind the measured variables.
Tiny furry clusters of green hug that soil beneath it, shimmering a little, kind of like stringy, caterpillar coils of velvet in the softest sunlight.
In actively grazed sites, domestic livestock grazing also appears to lead to clustered, rather than random, spatial distribution of soil resources.
There are fields of vegetables, growing in the sandy soil, and clusters of fruit trees shading the houses.
In the second step, a sensitivity analysis of the attributes is performed with MDS: each attribute is made "neutral" one at a time, by assuming the median rather than the extreme values in each grid node before the distance evaluation, and the consequent impact on the shape and centroid displacement of the clusters (soil types) in the MDS reference frame is calculated.
The dendrogram in Figure 7 presents grouping of soil characteristics in three main clusters.
