Replant Mortality Replacement Count

Budget block replant orders from confirmed dead positions plus explicit unlocated assumption and caller replant establishment, rounding each order separately; no missing-as-dead default or establishment guarantee.

Description

Confirmed dead vines and unlocated vines are different observations.

Confirmed dead vines and unlocated vines are different observations. Replant orders also depend on an assumed establishment fraction.

When to use Replant Mortality Replacement Count

Use this tool to budget block replant orders from confirmed dead positions plus explicit unlocated assumption and caller replant establishment, rounding each order separately; no missing-as-dead default or establishment guarantee.

Prepare vineyard measurements, dates or block records for the intended growing period. Keep weights, counts and weather observations in the stated units.

How to use Replant Mortality Replacement Count and understand its results

Prepare vineyard measurements, dates or block records for the intended growing period. Keep weights, counts and weather observations in the stated units.
Enter confirmedDeadVinesByBlock, unlocatedVinesByBlock, callerUnlocatedReplacementFractions, callerReplantEstablishmentFractions using the field table and calculation rules, then run the tool.
Read minimumConfirmedReplacementPositions, modeledGrossReplacementVineOrders, totalModeledGrossReplacementVines. 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
confirmedDeadVinesByBlock	Confirmed dead vines by block	list of number	Required
unlocatedVinesByBlock	Unlocated vines by block	list of number	Required
callerUnlocatedReplacementFractions	Caller unlocated replacement fractions	list of number	Required
callerReplantEstablishmentFractions	Caller replant establishment fractions	list of number	Required

Align nonnegative integer counts with unlocated replacement fractions in [0,1] and establishment fractions in (0,1]. Round each block separately and sum orders; report confirmed replacement positions separately.^[1]

Paired lists must be nonempty and have equal lengths.

order per block = ceil((confirmed dead + unlocated × replacement fraction)/establishment fraction)

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
minimumConfirmedReplacementPositions	Minimum confirmed replacement positions	list of number
modeledGrossReplacementVineOrders	Modeled gross replacement vine orders	list of number
totalModeledGrossReplacementVines	Total modeled gross replacement vines	number

Limitations and assumptions

Unlocated vines are not automatically treated as dead, and establishment is not guaranteed.

Numbers and computed results must be finite; overflow produces an error. Numeric lists are limited to 100,000 entries; the rules above may require smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Graft Success Rate Percent: Audit multi-batch graft take→rooting→saleable nested pipeline and distinct attrition, not simple binary seedling survival; unequal batch sizes are pooled by attempted grafts and stage quality criteria are caller established. For a complementary task, use Row Length Vine Count: Count endpoint-inclusive geometric vine positions for unequal measured row lengths, spacings and end exclusions; no area-density alias, field planting recommendation or rounding fractional plants.
