The Soils of Bulgaria offers a comprehensive analysis of the characteristics of soils and concepts on their magnitude. The purpose of the book is to introduce readers to the soil problematic and ecology in Bulgaria. The volume is divided into 3 parts. The first includes historical facts on soil research in Bulgaria, as well as general conditions and factors of soil formation, while the second applies an original pedological approach. The book’s third part focuses on essential information concerning land use/cover in Bulgaria. Each of the 13 chapters deals more specifically with fundamental chemical and physical soil properties, concepts of soil evolution, old and modern processes, geographic distribution, climatic conditions, topography, parent materials, plant associations, morphology and the relationship with different classification systems. The interactions between soil status and management are also highlighted. The use of the latest, statistically significant data ensures precise conclusions. The book also includes a large number of charts and new illustrations. The Soils of Bulgaria is crucial reading material for anyone interested in soil management and agriculture in Easter Europe, from students to policy makers and is also of particular interest for researchers in the field.

This book presents a systematic and analyzed available - own and published data on the content, composition and stocks of organic matter of the main soil types in Bulgaria. It is investigated variability of soil humus systems and their comparative characteristics by statistical methods of analysis and established relationships between some parameters associated with the processes of humus formation and equations are derived describing the relationships established. It is summarized available information of organic carbon composition; stocks in the soils of Bulgaria defined layers 0-25 cm, and the whole soil profile (0-100 cm), based on the data of the organic carbon content and bulk density, counting the soil surface of each soil type occupies on the territory of the country. Soils in Bulgaria are grouped according to the composition of soil organic matter and humus stability system.Details of this work can be used: by university and PhD students; researchers working on SOM; in theoretical developments concerning processes of humus formation; for for applicable purposes in drawing up models for the development of agriculture of the country and sustainable land management."

Here is a comprehensive analysis of chemical and physical soil properties, soil evolution, old and modern processes, geographic distribution, climatic conditions, topography, parent materials, plant associations, morphology, classification systems and more.

Soil Magnetism: Applications in Pedology, Environmental Science and Agriculture provides a systematic, comparative, and detailed overview of the magnetic characterization of the major soil units and the observed general relationships, possibilities, and perspectives in application of rock magnetic methods in soil science, agriculture, and beyond. Part I covers detailed magnetic and geochemical characterization of major soil types according to the FAO classification system, with Part II covering the mapping of topsoil magnetic signatures on the basis of soil magnetic characteristics. The book concludes with practical examples on the application of magnetic methods in environmental science, agriculture, soil pollution, and paleoclimate. - Provides an overview of the major findings of uncontaminated soil profiles and proposes a system of magnetic characteristics - Elucidates the relationship between geochemical and magnetic characteristics of different soil types, providing a basis for wider recognition and application of soil magnetism in classical pedagogical characterization of soils - Covers the peculiarities of the main taxonomic soil groups in terms of magnetic mineralogy and depth variations in concentration, grain size, and phase composition of iron oxides

Soil classification and terminology are fundamental issues for the clear understanding and communication of the subject. However, while there are many national soil classification systems, these do not directly correlate with each other. This leads to confusion and great difficulty in undertaking comparative scientific research that draws on more than one system and in making sense of international scientific papers using a system that is unfamiliar to the reader. This book aims to clarify this position by describing and comparing different systems and evaluating them in the context of the World Reference Base (WRB) for Soil Resources. The latter was set up to resolve these problems by creating an international 'umbrella' system for soil correlation. All soil scientists should then classify soils using the WRB as well as their national systems. The book is a definitive and essential reference work for all students studying soils as part of life, earth or environmental sciences, as well as professional soil scientists.
