O autorze

Prof. Pankaj Srivastava obtained M.Sc. Geology in 1986 and PhD in Earth Sciences in 1992 from University of Roorkee (now IIT Roorkee). The topic of his PhD dissertation was “A Holocene Soil Chrono association of the Gangetic Plains between Ramganga and Rapti rivers”. Prof. Srivastava has used micromorphology to explore soils and paleosols of the Himalayan Foreland Basin (HFB) to understand its evolutionary history. His lab on micromorphology in the University of Delhi has helped him to resolve several issues that are related to silicate weathering, pedogenesis, soil-geomorphology, polygenesis, pedogenic and non-pedogenic carbonates, diagenetic overprinting in lithified paleosols, and to provide basic principles of alluvial cyclicity in fluvial sediments. Prof. Srivastava is working on a mission to develop this technique further and disseminate the same as an important component of the academic curriculum in the country. His students are devoted to paleopedological research work covering the entire succession of the HFB from the oldest paleosols ca 31 Ma to the Holocene soils of the Ganga Basin. Prof. Srivastava has been actively collaborating with researchers from US, UK, and Germany for paleopedological studies.

 Dr D. K. Pal obtained his M.Sc. (Ag) degree in Agricultural Chemistry with a specialization in Soil Science in 1970 and was awarded his PhD degree in Agricultural Chemistry and continued his training as a DAAD Postdoctoral Fellow   in West Germany. The focus of his work has been major soil types of India that has expanded the basic knowledge in pedology, paleopedology, soil taxonomy, soil mineralogy, soil micromorphology and edaphology.  He has monitored several MSc and PhD students of land resource management. He has been an Invited Speaker at multiple national and international conferences and continues to serve as a Reviewer for many journals of national and international repute.  He has authored five books: three books published by Springer International Publishing AG, Cham, Switzerland, the fourth one published by the Clay Minerals Society of India, New Delhi in 2021, and the fifth one   published by the Indian Society of Soil Survey and Land Use Planning, Nagpur, in 2022. He has been an Awardee of several prestigious awards   and fellowships. He served as the Principal Scientist and Head, Division of Soil Resource Studies, ICAR-NBSS&LUP, Nagpur, and as a Visiting Scientist at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT)

This monograph covers uniqueness of micromorphology in resolving many important but enigmatic pedological issues such as clay illuviation, formation of pedogenic and non-pedogenic CaCO₃, modification of plasmic fabric, contemporary and relict pedogenic processes, polygenesis of soils in Alfisols, Mollisols, Ultisols, Vertisols and Inceptisols of the tropical Indian environments. Chapters in this title also include identification of paleosols, diagenetic overprinting of the pedofeatures in lithified paleosols, and alluvial cyclicity of the fluvial successions. The techniques mentioned in this title are of tremendous value in pedological and geological research for precise and unambiguous definitions of soil taxa to build the national soil information and refine the stratigraphy of the terrestrial sediments.

The information is for the benefit the students and researchers of pedology and geomorphology who often come across extreme difficulties in relating to examples applying the principles of soil formation from textbooks devoted almost exclusively to soils of the temperate climates. The format of this publication is arranged for a process-oriented text and figures on micromorphology of the tropical soils and paleosols as a reference for pedologists, earth scientists, M.Sc. and Ph.D. students, and also for land resource managers who are engaged in enhancing the productivity of such tropical soils in India and elsewhere.
