Petiole Nitrate Nitrogen Sufficiency Lookup
Audit actual petiole nitrate versus nitrate-N report bases with explicit atom/molecule masses and caller stage assay band; already N reports bypass conversion, not total N, fertilizer or universal sufficiency recommendation.
Description
Nitrate and nitrate-nitrogen reporting use different mass bases.
Nitrate and nitrate-nitrogen reporting use different mass bases. Nitrogen-equivalent conversion requires explicit compatible molecular masses.1
Enter nonempty aligned nonnegative assays/binary flags, positive masses with N mass smaller and two ordered nonnegative N-basis bounds. Return equivalents and outside indices.
When to use Petiole Nitrate Nitrogen Sufficiency Lookup
Use Petiole Nitrate Nitrogen Sufficiency Lookup when you need to evaluate the supplied records under the calculation and evidence rules below. No total-N measure, fertilizer recommendation or universal stage sufficiency range is supplied.
Prepare the measured vineyard records, aligned lists and independently verified local limits or catalog requested. Keep units, crop stages and observation periods consistent.
How to use Petiole Nitrate Nitrogen Sufficiency Lookup and understand its results
- Prepare the measured vineyard records, aligned lists and independently verified local limits or catalog requested. Keep units, crop stages and observation periods consistent.
- Enter observedPetioleNitrateMgKg, reportAlreadyAsNitrateNitrogenFlags, callerNitrogenAtomicMass, callerNitrateMolarMass, callerNitrateNitrogenBandMgKg using the field table and calculation rules, then run the tool.
- Read nitrateNitrogenEquivalentMgKg, petioleSamplesOutsideCallerNitrateNitrogenBand. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| observedPetioleNitrateMgKg | Observed petiole nitrate mg kg | list of number | Required |
| reportAlreadyAsNitrateNitrogenFlags | Report already as nitrate nitrogen flags | list of number | Required |
| callerNitrogenAtomicMass | Caller nitrogen atomic mass | number | Required |
| callerNitrateMolarMass | Caller nitrate molar mass | number | Required |
| callerNitrateNitrogenBandMgKg | Caller nitrate nitrogen band mg kg | list of number | Required |
Enter nonempty aligned nonnegative assays/binary flags, positive masses with N mass smaller and two ordered nonnegative N-basis bounds. Return equivalents and outside indices.
nitrateN=reported if already N; otherwise reported×NAtomicMass/nitrateMolarMass Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| nitrateNitrogenEquivalentMgKg | Nitrate nitrogen equivalent mg kg | list of number |
| petioleSamplesOutsideCallerNitrateNitrogenBand | Petiole samples outside caller nitrate nitrogen band | list of number |

}Limitations and assumptions
No total-N measure, fertilizer recommendation or universal stage sufficiency range is supplied.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Petiole Potassium Sufficiency Lookup: Potassium assay results may be reported as elemental K or K2O. A common reporting basis is needed before comparing a petiole band. For a complementary task, use Magnesium Petiole Sufficiency Lookup: Dry- and fresh-mass tissue assays need a shared basis before band comparison. Dry matter fraction converts concentration per dry mass to fresh-mass concentration.
