ABSTRACT
Lovětín was a medieval village located in the Bohemian-Moravian Upland (Czech Republic). It existed ap-
proximately between the 14th and the 16th century and was comprised of up to 20 farmsteads. Arable farming
based on a short-fallow cultivation system was its main means of subsistence. The fields of the village consisted
of two main field areas (128 and 77 ha) and six smaller field areas (up to 8 ha). Our study focused on finding out
how human activities have impacted the soil environment imprinted in its geochemical characteristics. The
design was based on a 100-m grid (in some cases, a 50-m grid) covering the entire field system (plužina) of the
village; soil samples were taken from the B horizon at a depth of 15 cm. The analysis was based on XRF spec-
trometry, returning near total concentrations of the elements. The statistical and GIS analyses were performed on
338 samples, measuring the following elements: Al, Si, K, Ti, Cr, Mn, Fe, Ni, Cu, Zn, As, Rb, Sr, Zr, Pb, Th, LE
(light elements – combined concentrations for H to Na). The results of the analyses were processed by PCA after
ilr transformation. The PCA indicated 16 principal components, of which three were interpreted as direct pro-
ducts of past human activities. The main elements reflecting human activities were Mn, Sr, Th, K, Zn; P con-
tributed also to the interpretations, although it was detected and measured only in 132 cases. Some of the
elements were spatially connected to the village in terms of their concentrations, but the PCA did not reveal a
strong connection (Ti, Cr, Ni, Cu, Zr). The spatial distribution of the principal components was varied, indicating
a diversity in the spatial distribution of agricultural activities or of their intensity, as well as differences in land
use management. Management was most intensive in the vicinity of the village built-up area up to a distance of
300–400 m. The village was probably deserted due to inadequate soil management strategies.
1. Introduction
Human-soil relationships have been the focus of a large number of
studies in the fields of natural sciences and archaeology (Bork et al.,
1998; Walkington, 2010). The spectrum of sub-topics is wide and can
be divided into: i) links between past settlements and basic soil types; ii)
human influence on the pedogenesis and the topic of anthropogenic
soils; iii) detailed on-site analysis (soil sometimes serves as an archive of
human activities). The first sub-topic has a long tradition; e.g. in central
Europe, Neolithic cultures and their links to loess substrates or cher-
nozemic soils have been studied (Rulf, 1983, 1989, 1994) or the im-
pacts of settlers colonising regions of higher altitudes (Dreslerová et al.,
2013; Dreslerová and Kočár, 2013). The second sub-topic is probably
the most studied one (e.g. Pears, 2012) and well-known outside the
archaeological community. The traditional question of chernozems in
temperate Europe (Eckmeier et al., 2007) is connected to other dis-
ciplines (hypotheses of the influence of large herbivores; see Vera,
2000). There are also studies on soils anthropogenically ameliorated by
micro-charcoals (Schier et al., 2013) and the prevailing anthropogenic
characteristics of soils in the Amazon region (Mayle and Iriarte, 2014;
Lewis et al., 2017). The third sub-topic of on-site analyses (e.g.
Salisbury, 2013, Hejcman et al., 2013b) is often studied because the
application of geochemical analyses is almost a standard in archae-
ological research across Europe. On-site application has the advantage
of a detailed spatial view. Although a detailed view can be applied to
prehistoric sites (see Kristiansen (2001), who studied the diversity of
soil types based on prehistoric land use), using this practice for historic
sites enables us to work with the historic context (see Thurston (2009),
using the social context obtained from written sources to better inter-
pret the human-soil relationship on islands in the northern Atlantic).
Although the social context can significantly influence the environment
and soils, such studies are still scarce (Jones, 2009; Redman, 1999).
Historic eras are important not only in terms of written sources. For
example, the medieval era brought new technologies, new types of
