Description
Return measuredMass*dilution/sampledDryMass and multiply by referenceDryMass for referenceMass.
Soil and plant analytical results depend on sample mass, extraction volume, dilution, blanks and dry-matter basis. Concentration in an extract is distinct from analyte mass per soil mass or an inventory per field area. A unit conversion does not convert between analytical methods or establish nutrient availability.
Return measuredMass*dilution/sampledDryMass and multiply by referenceDryMass for referenceMass.
When to use this tool
Use Foliar Assay Reference Leaf Dry Basis when checking the stated benign analytical concentration, inventory or calibration basis.
How to use the tool and how it works
- Enter measuredMass, dilution, sampledDryMass, referenceDryMass. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read massPerDryMass, referenceMass. Use the output convention below.
Require nonnegative measured analyte mass/reference dry mass and positive dilution/sample dry mass. Return measuredMass*dilution/sampledDryMass and multiply by referenceDryMass for referenceMass.1

}Limitations and assumptions
- Measured mass must match the stated pre-dilution convention; no tissue diagnosis or suitable nutrient concentration is selected.
- 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 laboratory methods, compatible units and qualified laboratory/agronomic assessment for actual analytical interpretation, chemical handling or field management.
