Soil consistency is the strength with which soil materials are held together or the resistance of soil to deformation and rupture. Soil consistency is measured for wet, moist and dry soil samples. For wet soil the consistency is expressed as both stickiness (ability of soil to adhere to other objects) and plasticity (ability of soil material to change shape but not volume). The stickiness may be classified as ‘non sticky’ and ‘sticky’ whereas the plasticity can be rated as non plastic, slightly plastic, plastic, very plastic etc. By feeling the soil resistance to pressure & rupture it can be rated as loose, friable, firm, hard and their further subcategories.
