Agriculture Soil Texture Clay Percentage Calculator
Expand independently isolated clay dry aliquot masses to whole matched dispersion using explicit aliquot-to-whole volume factors before pooling recovered sand+silt and uncaptured mass. Different from sieved sand or silt-by-fine-minus-clay sedimentation; caller establishes method and applicability, not texture identity or an agronomic recommendation.
Description
Clay measurements from an aliquot need a declared expansion to the whole dispersion.
Clay measurements from an aliquot need a declared expansion to the whole dispersion.1
Expanded recovered percentage and mass closure depend on that factor. Use Agriculture Soil Texture Clay Percentage Calculator to evaluate the supplied inputs under the model explained below.
When to use Agriculture Soil Texture Clay Percentage Calculator
Use Agriculture Soil Texture Clay Percentage Calculator to evaluate the supplied inputs under the model explained below. Establish the units, measurement scope and model assumptions before entering values.
How to use Agriculture Soil Texture Clay Percentage Calculator and understand its results
- Establish the units, measurement scope and model assumptions before entering values.
- Enter Observed separated clay mass kg, Observed separated sand silt mass kg, Uncaptured clay analysis mass kg, Caller matched aliquot to whole dispersion factors using the field table and validation rules below, then run the tool.
- Read Observed recovered component percent, Recovered mass closure fraction; interpret the units, signs, ordering and unknown-value placeholders described below.
- Correct reported input errors and rerun. Apply successful results according to their specific meanings and check the assumptions before using them in a decision.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedSeparatedClayMassKg | Observed separated clay mass kg | array of number | Required; constraints below |
| observedSeparatedSandSiltMassKg | Observed separated sand silt mass kg | array of number | Required; constraints below |
| uncapturedClayAnalysisMassKg | Uncaptured clay analysis mass kg | array of number | Required; constraints below |
| callerMatchedAliquotToWholeDispersionFactors | Caller matched aliquot to whole dispersion factors | array of number | Required; constraints below |
Enter nonempty aligned nonnegative measured clay, separated sand/silt and uncaptured masses in kg, plus matched positive aliquot expansion factors at least 1. Expand clay by its factor, require positive recovered=expandedClay+sum(sandSilt), and return 100×expandedClay/recovered and recovered/(recovered+uncaptured). No factor, sedimentation method or texture classification is selected.
expandedClay=ΣmeasuredClay×callerAliquotFactor; percent=100expandedClay/recovered; closure=recovered/total Use the field order, units and branch conditions described above.
| Output field | Meaning | Value type |
|---|---|---|
| observedRecoveredComponentPercent | Observed recovered component percent | number |
| recoveredMassClosureFraction | Recovered mass closure fraction | number |

}Limitations and assumptions
Expanded recovered percentage and mass closure depend on that factor. Apply the exact scope and assumptions explained above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse arrays fail validation. Domain-specific bounds, alignments and supported tokens are explained above; extremely large inputs or outputs can also be rejected. Input errors differ from successful false results, empty match lists and unknown-evidence placeholders.
