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 |
