Description
Return dry bulk core density.
Soil measurements distinguish bulk volume, pore volume, water mass, fine earth and excluded rock or sand. Gravimetric water content and volumetric water content have different denominators; accessible-pore shares and bulk-volume shares are not interchangeable. Supplied normalization bounds do not establish a validated retention curve.
Return dry bulk core density.
When to use this tool
Use Core Density Dry Mass Term when checking the stated soil water, mass, pore or aggregate basis.
How to use the tool and how it works
- Enter dryMass, coreVolume. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read density. Use the output convention below.
Return dry bulk core density. Require dryMass >= 0 and coreVolume > 0; density = dryMass/coreVolume.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| dryMass | Dry Mass | Required. Finite number; minimum 0. |
| coreVolume | Core Volume | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| density | Mass or count divided by the explicitly stated volume/area basis; use compatible units. | Required. Finite number. |

}Limitations and assumptions
- This is dry mass per bulk volume, not particle density; moisture removal, rock basis and actual soil state are not verified.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified sampling, density and moisture measurements with the intended complete soil model for field water status, structure or management conclusions.
