Based on particle size, the soils can be classified as under, adopting the IS soil classification system:

mm     mm     mm     mm     mm     mm     mm     mm

All soils, as per the Indian Soil Classification System, are divided into three main groups:

(a) Coarse-grained soils, having more than half the total material by weight, larger than 75 micron sieve size.

(b) Fine-grained soils, having more than half the total material by weight smaller than 75 micron sieve size.

(c) Highly organic soils: these soils contain larger percentages of fibrous organic matter such as peat and particles of decomposed vegetation. Further, certain soils containing shells, concretions, cinders and other non- soil materials in sufficient quantities are also involved in this group.
