Soil consistency is the strength with which soil materials are held together or the resistance of soils to deformation and rupture. Soil consistency is measured for wet, moist and dry soil samples.
Consistency
Class	In the field	
Extremely weak	The soil slips between the fingers when it is pressed in a hand.	
Very weak	A finger can be easily pressed up to 25 mm into the sample.	
Weak	A finger can be easily pressed up to 10 mm into the sample.	
Moderately weak	The soil can be molded by light pressure	
Moderately solid	The soil can't be molded with fingers, but can be hand rolled to strings with a thickness of 3 mm.	
Solid	The thumb can easily press the soil.	
Moderately hard	The thumb can leave a shallow imprint.	
Hard	The soil crumbles and breaks when rolled to string with a thickness of 3 mm.
