SSAC 505/ AP 505 SOIL GENESIS, CLASSIFICATION AND SURVEY                                                           (2L+2P) II

Objective
To teach the students concept of pedon, Pedology as a core discipline of Soil Science, factors and processes of soil formation, soil classifications systems, survey and cartography. Main emphasis is on enabling the students to conduct soil survey and interpret soil survey reports for sustainable land use and planning.

Theory

UNIT I
Historical developments in Pedology; characterization and classification of rocks and minerals; weathering of rocks and minerals, weathering sequences of minerals with special reference to Indian soils; soil forming processes and factors of soil formation.

UNIT II
Concept of soil as an individual entity; soil classification – principles and historical development; soil classification systems - historical developments and modern systems of soil classification with special emphasis on soil taxonomy.

UNIT III
Soil survey and its types; soil survey techniques - conventional and modern; soil series – characterization and procedure for establishing soil series; benchmark soils and soil correlations; soil survey interpretations; soil mapping, thematic soil maps, cartography, mapping units, techniques for generation of soil maps; landform – soil relationships; application of remote sensing and GIS in soil survey and mapping; major soil groups of India.

UNIT IV
Land capability classification and land irrigability classification; land evaluation and land use type (LUT) – concept and application; approaches for managing soils and landscapes in the framework of agro-ecosystems.

Practicals
Morphological properties of soil profile in different landforms; classification of soils using soil taxonomy; calculation of weathering indices and its application in soil formation; grouping soils using available data base in terms of soil quality; aerial photo and satellite data interpretation for soil and land use; cartographic techniques for preparation of base maps and thematic maps; processing of field sheets, compilation and abstraction of maps in different scales
