'''Soil Consistency''' the feel of the [[Soil|soil]], reflecting relative resistance to pressure: eg friable, firm, hard, loose, plastic. The term soil consistency is used to describe the resistance of a soil at various moisture contents to mechanical stresses or manipulations. It is commonly measured by feeling and manipulating the soil by hand or by pulling a tillage instrument through it. The consistency of soils is generally described at three soil moisture levels: wet, moist and dry. Terms used to describe soil consistency at these three moisture levels are shown in the table.

Terms such as weakly cemented, strongly cemented, and indurated are used to define categories of cementation. Consistency has importance for the practical use of soils such as soil tillage and compaction by farm machinery.

[[Acid Basin Clay|acid basin clay]]s are featured by heavy soil consistency (making the soils difficult to plough both when wet and when dry). Noncalcareous Grey Floodplain soils and Noncalcareous Dark Grey Floodplain soils show firmer consistency. Calcareous Brown Floodplain soils develop more friable consistency.
