This book describes a wide range of soils, from the humid
subtropical coast of the Black Sea to the frozen peaks of the High
Caucasus with more than 5.000 meters above sea level and from
extremely humid areas in the West to dry, semi-desert regions in
the East, with an enormous variety of rock parent materials, a very
accentuated hydrology and a topography, ranging from large plains,
hilly regions to steep and strongly dissected slopes and gorges in
the High and Lower Caucasus. There is no other country in the world
the size of Georgia with such a variety of soil forming conditions
and soils. Therefore, V V Dokuchaev, one of the founders of the
genetic soil classification, called Georgia an "Open-Air Museum of
Soils". The book is subdivided into 6 chapters. In Chapter 1, the
physiography of Georgia and the factors of soil formation such as
topography, geology, climate and vegetation are described, followed
by Chapter 2, with the detailed description of 21 soil groups,
their morphological, physical and chemical characteristics, their
many different subtypes and variations, and their ecology, based on
72 tables, 25 figures and 20 photos. Moreover, the location of each
soil and its surface in % of the total surface of Georgia are
explained, including the history of their discovery and
investigation together with the relevant literature. In Chapter 3,
the overall ecological conditions, especially problems of soil
erosion by water and wind and the soil contamination by heavy
metals and radionuclides are described, followed by Chapter 4 with
an explanation of the soil use, based on physical and chemical soil
characteristics. Two further chapters with references and soil
photos conclude the book, which is written by Professor Tengiz F
Urushadze from the Agricultural University of Georgia in Tbilisi
and Professor Winfried E H Blum from the University of Natural
Resources and Life Sciences (BOKU) in Vienna, Austria.
