Black soils:

The parent material for most of the black soil are the volcanic rocks that were formed in the Deccan Plateau (Deccan and the Rajmahal trap).
In Tamil Nadu, gneisses and schists form the parent material. The former are sufficiently deep while the later are generally shallow.
These are the region of high temperature and low rainfall. It is, therefore, a soil group typical to the dry and hot regions of the Peninsula.
A typical black soil is highly argillaceous (consisting of or containing clay)
The black soil is highly retentive of moisture. It swells greatly on accumulating moisture. Strenuous effort is required to work on such soil in rainy season as it gets very sticky
