Answer 1

Pebbly and gravelly soils are rare

Kankar (calcareous concretions) beds are present in some regions along the river terraces.

The soil is porous because of its loamy (equal proportion of sand and clay) nature.

Porosity and texture provide good drainage and other conditions favorable for agriculture
