DeepDyve eBooks - A Treatise of Indian and Tropical Soils

Pal, D. K.

Pages: 1 –7

[The Indian subcontinent, which collided with the Asian mainland during the Eocene period, is a very old mass and has not been under water since the Carboniferous period. A girdle of high mountains, snow fields, glaciers and thick forests in the north, seas washing lengthy coasts in the...

Cracking Clay Soils (Vertisols): Pedology, Mineralogy and Taxonomy

Pal, D. K.

Pages: 9 –42

[A synthesis of recent developments in the pedology of Vertisols achieved through the use of high resolution micro-morphology, mineralogy, and age control data along with their geomorphic and climatic history, has contributed to our understanding of how the climate change-related pedogenic...

Red Ferruginous Soils: Pedology, Mineralogy and Taxonomy

Pal, D. K.

Pages: 43 –69

[Red ferruginous (RF) soils of Indian tropical environments belong to five taxonomic soil orders (Entisols, Inceptisols, Alfisols, Mollisols and Ultisols), which clearly indicate that tropical RF soils in India have captured wide soil diversity. The spatially associated Ultisols with acidic...

Soils of the Indo-Gangetic Alluvial Plains: Historical Perspective, Soil-Geomorphology and Pedology in Response Climate Change and Neotectonics

Pal, D. K.

Pages: 71 –90

[Indian earth scientists and soil scientists based on large number of well-presented pedons in the Indo-Gangetic Alluvial Plains (IGP), spread along the west hot arid climate to per-humid climate in the east, have led to new perspectives on the historical development of the IGP and the soils...

Conceptual Models on Tropical Soil Formation

Pal, D. K.

Pages: 91 –96

[Use of models to explain adequately the formation of tropical soils indicates that although among the most popular models applicable in soil formation, the residua and haplosoil models have relevance to formation and persistence of Indian tropical soils, they cannot explain the existence of...

Land and Soil Degradation and Remedial Measures

Pal, D. K.

Pages: 97 –114

[Most published research on soil degradation in general emphasizes the role of anthropogenic factors. Even among the natural soil degradation processes the regressive pedogenic processes that lead to the formation of CaCO3 and concomitant development of subsoil sodicity and the adverse effects of...

Clay and Other Minerals in Soils and Sediments as Evidence of Climate Change

Pal, D. K.

Pages: 115 –125

[Identification of paleoclimatic signatures in paleosols is a major challenge to soil scientists. It is realized that the clay minerals of the paleosols are potential promising materials for documenting and resolving a wide spectrum of different genetic environments and reactions. It is often...

Linking Minerals to Selected Soil Bulk Properties

Pal, D. K.

Pages: 127 –152

[Minerals in soils are the result of both inheritance and authigenic formation of both primary and secondary minerals. Comprehensive reviews on the soil clay minerals and other minerals in the past indicate that there are not many attempts to show the influence of minerals in soil genesis and...

Importance of Pedology of Indian Tropical Soils in Their Edaphology

Pal, D. K.

Pages: 153 –174

[Many consider that the soils of the tropical soils are acidic, infertile, and that they do not support a reasonable sustained agricultural production. Recent research in agricultural production in tropical Asia and Latin America indicate that universal infertility of tropical soils is a myth. In...

Summary and Concluding Remarks

Pal, D. K.

Pages: 175 –180

[The treatise of Indian and tropical soils ends with a chapter ‘Summary and Concluding Remarks’, which projects a concise but a precious synthesis of unique research results obtained by the soil and earth scientists on major soil types of tropical Indian environments. In the past, much valuable...
