Soil water storage properties

Recommended values for porosity, field capacity and wilting point for different soils.¹
Link to this table

Soil	Porosity (volume/volume)	Field capacity (volume/volume)	Wilting point (volume/volume)	Porosity minus field capacity (volume/volume)²	Field capacity minus wilting point (volume/volume)³
Sand	0.43	0.17	0.025 to 0.09	0.26	0.11
Loamy sand	0.44	0.09	0.04	0.35	0.05
Sandy loam	0.45	0.14	0.05	0.31	0.09
Loam	0.47	0.25 to 0.32	0.09 to 0.15	0.19	0.06
Silt loam	0.50	0.28	0.11	0.22	0.17
Sandy clay loam	0.4		0.07
Clay loam	0.46	0.32	0.15	0.14	0.17
Silty clay loam	0.47 to 0.51	0.30 to 0.37	0.17 to 0.22	0.16	0.14
Sandy clay	0.43		0.11
Silty clay	0.47		0.05
Clay	0.47	0.32	0.20	0.15	0.12
