Description
Format three supplied fertilizer-label percentage values as a grade token.
Agricultural chemical records distinguish wet-basis moisture, dilution direction, charge equivalents and supplied reporting bases. A fertilizer-grade token preserves reported percentages without converting elemental and oxide conventions or validating composition. Retest-date gaps and lot labels do not establish product safety or authorized use.
Format three supplied fertilizer-label percentage values as a grade token.
When to use this tool
Use Fertilizer Grade NPK Token when you already have nitrogenPercent, phosphateLabelPercent, potashLabelPercent and need to format three supplied fertilizer-label percentage values as a grade token.
How to use the tool and how it works
- Enter nitrogenPercent, phosphateLabelPercent, potashLabelPercent. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read gradeText. Use the output convention below.
Require each nitrogen/phosphate/potash label percentage individually in [0,100]; join their numeric spellings with hyphens.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| nitrogenPercent | Nitrogen Percent | Required. Finite number; minimum 0; maximum 100. |
| phosphateLabelPercent | Phosphate Label Percent | Required. Finite number; minimum 0; maximum 100. |
| potashLabelPercent | Potash Label Percent | Required. Finite number; minimum 0; maximum 100. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| gradeText | Each supplied label percentage joined with hyphens; no sum constraint, product validation or elemental/oxide conversion. | Required. Text; maximum UTF-16 length 8192. |

}Limitations and assumptions
- No combined-sum check or elemental/oxide conversion is performed. Reporting bases and product label are supplied; this does not verify a valid grade, composition, registration or suitable application.
- 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
Review original laboratory, product, sample and controlled-label records with the complete appropriate assessment. Verify units and reporting bases before applying local factors; these tools do not select chemicals, preparation procedures or application amounts.
