Agriculture Soil Texture Sand Percentage Calculator
Audit actual separated sand component across paired particle-fraction tests and independently uncaptured mass; recovery closure explicit, not complement of unverified percentages. Caller independently establishes units, regime, calibration and applicability; this does not establish design-code compliance, authenticity, operational safety, treatment efficacy or a validated forecast.
Description
Sand percentage can be based on recovered material while uncaptured mass is tracked separately.
Sand percentage can be based on recovered material while uncaptured mass is tracked separately.1
That closure check should not be confused with assigning the lost mass to a texture component. Use Agriculture Soil Texture Sand Percentage Calculator to evaluate the supplied inputs under the model explained below.
When to use Agriculture Soil Texture Sand Percentage Calculator
Use Agriculture Soil Texture Sand 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 Sand Percentage Calculator and understand its results
- Establish the units, measurement scope and model assumptions before entering values.
- Enter Observed separated sand mass kg, Observed separated silt clay mass kg, Uncaptured sand analysis mass kg 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 |
|---|---|---|---|
| observedSeparatedSandMassKg | Observed separated sand mass kg | array of number | Required; constraints below |
| observedSeparatedSiltClayMassKg | Observed separated silt clay mass kg | array of number | Required; constraints below |
| uncapturedSandAnalysisMassKg | Uncaptured sand analysis mass kg | array of number | Required; constraints below |
Enter nonempty aligned nonnegative separated sand, separated silt/clay and uncaptured-analysis masses in kg. Recovered=sum(sand)+sum(siltClay) must be positive. Return 100×sand/recovered and recovered/(recovered+uncaptured). Uncaptured mass is not assigned to sand, and no standard texture class is inferred.
recoveredSandPercent=100Σsand/(Σsand+ΣsiltClay); closure=recovered/(recovered+uncaptured) 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
That closure check should not be confused with assigning the lost mass to a texture component. 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.
