Pomelos and grapefruits

1. Scope and Applicability

This PCR guides a foreground data package for fresh whole pomelos and grapefruits from the declared orchard or grove production cycle through harvest, optional on-farm conditioning, and the declared farm-gate or pack-house hand-off. It covers perennial orchard establishment when that activity is included in the study, productive orchard care, irrigation, nutrient and crop-protection management, harvest rounds, and pre-gate sorting, washing, cooling, and primary packing when present.

Seedling and grafted-tree nursery production, breeding, juice and concentrate manufacture, cutting, peeling, drying, cooking, retail, consumer storage and use, and post-gate distribution are outside the default boundary. Durable orchard infrastructure, machinery, buildings, and irrigation assets are excluded unless separately attributed. Field residues, culls, rejected fruit, wastewater, and packaging waste remain in the foreground until their declared fate is recorded.

Required qualifiers	species and cultivar group; production geography; orchard age and productive status; planting density; crop-year and harvest dates; irrigated or rain-fed status; nutrient product and nutrient basis; crop-protection program; marketable yield; cull and residue fate; washing, cooling, and packaging state; declared gate

When constructing a foreground data package, the items listed in Required qualifiers must be declared in dataset metadata, process notes, reference-flow comment, product description, or an equivalent data package field. The reference product identity follows the declared qualifiers; no nearby citrus product is substituted.

This reference UUID denotes the fresh, unprocessed farm-gate product. Verify actual species, product state and handoff before applying the binding. An independent pack-house, further-processed or otherwise incompatible output requires separately verified identity and must not inherit this UUID. Identity verification does not change the actual system boundary or quantity-normalization requirements of this PCR.

The sole reference output is reference_product_at_declared_handoff at declared_reference_handoff, a mandatory measurement of the actual accepted product at the already declared gate. Process conditioning_and_farm_gate remains conditional: omission of its physical activities does not remove this reference. Select the actual last included product handoff and record its process/output id; accept only the same species, physical state, grade, moisture basis and gate as Section 3. The prior farm_gate_product_output row is the measured output of its actual operation when active, not an additional final sale. No bypass creates processing, a yield assumption, an extra burden or a change of product boundary.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_citrus_mass	harvested fruit, marketable fruit, culls, and residues	Mass	kg	Weigh marketable, downgraded, rejected, field-loss, and residual fruit streams separately and reconcile them before conversion to the 1,000 kg reference output.

nutrient_product_basis	fertilizer and soil-amendment inputs	Product and nutrient mass	kg product, kg N, kg P2O5, kg K2O	Give every actual fertilizer or amendment product its own card, retaining physical product mass, formulation, nutrient composition and application records. Nutrient quantities are not additional inputs of the same product; collection or group identifiers cannot substitute for a concrete flow identity.
water_delivery_basis	irrigation, fertigation, washing, and source withdrawal	Volume	m3	Keep crop irrigation, fertigation carrier water, post-harvest washing water, and natural-resource withdrawal as distinct records and disclose the meter or water-balance basis.
postharvest_mass_reconciliation	sorting, washing, cooling, and packing	Mass and moisture	kg and declared fraction	Retain measured soil removal, water uptake, cooling loss, culls, and packing loss separately from harvested fruit mass and disclose the reconciliation.

Marketable fresh whole pomelo or grapefruit (farm_gate_product_output)

Record the measured accepted output of conditioning_and_farm_gate only when that operation actually occurs. Preserve species, condition, grade, moisture, lot and its real outgoing gate.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_citrus_output	orchard and harvest operations producing pomelos, grapefruits, or multiple marketable grades	Allocate shared orchard and harvest inputs to product grades or species by measured marketable mass when the records support mass allocation. If quality grades have materially different economic functions, disclose and justify an alternative allocation before use.	iso-14044-2006; mass-balance-identity
allocation_residue_fate	culls, residues, and packaging waste	Treat culls, residues, and waste as waste flows unless a documented recipient and intended use support a co-product claim. Record any avoided-product or substitution claim separately from the foreground inventory.	iso-14044-2006; mass-balance-identity

Concrete cards do not inherit numerical ranges from the former aggregate card. Determine quantities from original records, stock/meter reconciliation and the declared reference flow; no default quantity or numeric screen is supplied without evidence matching the identity, unit, period and boundary. Missing range evidence is a quality disclosure, not zero use or proof of completeness.

rule_id	Applies to	Rule	source_ids
allocation_residual_precedence	remaining common burden with no specified primary branch	Resolve any study-specific joint-product instruction in this PCR that has no specified primary branch using this precedence; retain an already explicitly prescribed category-specific primary method. First directly assign separable output-specific activities. For the remaining common burden B, use a physical driver d_i only when measured operation or biological-service records demonstrate the causal consumption represented by that driver. A product being weighable, valuable or lower grade alone is insufficient; do not switch arbitrarily between area, time, mass and revenue. For comparable grades receiving the same common handling, measured processed mass is applicable only with the same service demand, state and moisture basis demonstrated. Share a_i=d_i/sum(d_j); B_i=Ba_i. If no defensible causal physical driver exists for that common operation, use gate- and period-matched economic shares a_i=(q_ip_i)/sum(q_j*p_j), with the complete independently intended output set, compatible quantity/price units, currency, representative prices and values before output-specific downstream processing. Missing price or denominator evidence makes the allocated result incomplete, not a zero-priced product or a single-output system. Report shares summing to one and sensitivity to a material alternative; an alternative is not an interchangeable primary result. Waste, retained residues and internal transfers receive no co-product share, while their attributable production/handling burdens remain with the producing saleable route. Retain unallocated physical quantities and mass balances separately. This branch gives no automatic substitution credit; any separately scoped substitution analysis retains the gross inventory and its actual displaced-function evidence.	ghg-protocol-product-standard-2011

8. Foreground Data Collection, Calculation, and Quality Rules

Specific input identification before dataset completion

Identify the actual input for this operation from supplier specifications, equipment and primary records. This is a mandatory collection requirement, not an exchange. Before dataset completeness, represent each used material, formulated product, carrier or independently purchased service by one physically specific card with its native quantity/property; confirm a compatible UUID, or retain an explicit unresolved identity and do not claim a fully linked dataset. Do not substitute a conditional example for an unknown actual input, invent a recipe, omit required use or infer zero from missing records. Attribute shared use, reusable assets and inclusive services once; preserve the original stage/period and measured throughput link to final reference output. The former aggregate range is not a component limit or consumption default.

requirement_id	collection_protocol_id	Preserved collection scope
crop_protection_input_specific_input	cp_nutrient_and_protection_records	Operation orchard_cultivation: Record herbicides, fungicides, insecticides, biological controls, and adjuvants crossing the boundary, retaining formulated product and active-ingredient quantities where available. Original quantity method: Sum invoices, spray logs, application records, and stock reconciliation for the represented orchard year.

Original quantity method: Sum fuel receipts, tank records, or machine-hour calculations assigned to the represented orchard year.

Original quantity method: Record container counts, material type, tare, reuse cycles, and loss or replacement records attributable to the campaign.
harvest_support_fuel_specific_input	cp_harvest_and_packaging_records	Operation harvest_and_field_handling: Record fuel used for harvest aids, orchard access, and movement of fruit to the on-farm handling point before the declared gate. Original quantity method: Sum campaign fuel records or machine-hour calculations and allocate them to the represented harvest output.
primary_packaging_specific_input	cp_harvest_and_packaging_records	Operation conditioning_and_farm_gate: When primary packaging crosses the boundary before the declared gate, record the actual packaging material, mass, format, and reuse or loss status. Original quantity method: Sum packaging issue records and allocate packaging mass to packed fruit output; record loose or reusable formats separately.

Retain raw site, lot, cycle and stage quantities and denominators in each collection protocol. Reconcile stocks, losses, moisture and co-product attribution first, then normalize: normalized exchange = attributable raw exchange × declared reference quantity / accepted hand-off product quantity on the same boundary and measurement basis. Apply perennial-establishment and shared-operation attribution before this normalization. Never set an internal-transfer quantity equal to the final reference quantity. Per declared reference flow means the amount, unit and product state in section 3; the data package must declare its actual route and gate.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
calc_orchard_year_normalization	all crop-year rows	Divide the attributed orchard-year inventory by accepted fresh whole fruit mass at the declared gate and scale to 1,000 kg.	block area, attributed input records, accepted output mass	normalized PCR inventory	mass-balance-identity
calc_nutrient_equivalents	fertilizer and soil-amendment rows	nutrient equivalent = formulated product mass × documented nutrient fraction; retain product mass and nutrient basis as separate fields.	product mass, N/P2O5/K2O fraction	nutrient-equivalent inputs	fao-gap-framework-2003
calc_water_withdrawal_balance	irrigation and fertigation	withdrawal = source withdrawal records reconciled to delivered water and declared return or consumption balance; do not infer withdrawal from rainfall alone.	source meters, delivered water, return flow	water withdrawal and delivered irrigation inputs	fao-crop-evapotranspiration-56
calc_citrus_mass_balance	harvest, conditioning, and gate output	harvested mass = accepted product + culls + recorded field, sorting, and packing losses; investigate unexplained residual mass.	lot weights and waste records	reconciled product and waste streams	mass-balance-identity
chemical_species_mass_accounting	elementary_nutrient_emissions	Final elementary exchanges use the mass of the identified substance and one actual receiving compartment. Keep nutrient/activity ledgers separate: species-specific N2O-N × 44/28 gives N2O, NH3-N × 17/14 gives NH3, nitrate-N × 62/14 gives nitrate, and phosphate-P × 95/31 gives phosphate. If the selected flow is elemental phosphorus instead, report kg P and convert phosphate mass by 31/95 only when that species basis is evidenced. Apply a conversion exactly once only when the method output is on the elemental basis; measured compound mass is not reconverted. Total nutrient losses cannot be assigned to a single species without a supported split, and residual/retained soil nutrient is not an emission. Keep direct/indirect pathway ledgers and avoid repeating a pathway already included in the chosen method or upstream inventory. Factor uncertainty ranges screen factors on their stated basis, not final compound amounts or admissible site emissions. Normalize the attributable compound mass once using the accepted reference quantity and the matched measured output. Unknown activity, identity or compartment remains an evidence gap and blocks a completeness claim.	cp_nutrient_and_protection_records; species-specific activity ledger, method pathway and factor basis, matched accepted output	Identity-specific exchanges and reconciled activity records

Environmental Coverage Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
calc_managed_environment_coverage	actual managed-production nodes	For the actual owned managed-production node(s), require an applicability ledger for direct soil N2O, volatilisation/deposition-derived indirect N2O, leaching/runoff-derived indirect N2O, NH3/NOx and nutrient losses, plus actual liming/urea-use CO2. Primary calculation precedence is a representative pathway measurement, then a validated site/national method applicable to the crop, soil and management; otherwise use the compatible 2006 IPCC/2019-refined managed-soil equations and climate/input-specific factor selection for N2O and lime/urea CO2. Retain the exact edition, equation, tier, activity and factor units, climate and management applicability; no universal dose or emission factor is prescribed. Non-soil/protected routes need a method valid for their actual medium; do not force soil factors onto an inapplicable route. Use the same period/field N ledger for synthetic and organic additions, residues, actual relevant mineralisation/organic-soil and excreta pathways; demonstrate absent pathways rather than infer zero. Calculate direct and each indirect component separately, then assign each once to matching existing or new concrete cards; never add a total to its components. Convert N2O-N to molecular N2O by 44/28 once. NH3, NOx and nutrient/pesticide loss require an applicable measured or documented substance/fate model; total N/P or an unexplained balance residual is not a compound release. Keep actual receiving compartments and molecular versus elemental/reporting bases explicit; indirect formation does not remove the same N from the source ledger twice. Include actual local combustion releases separately using fuel-specific combustion-only methods; purchased electricity/heat/services retain upstream coverage once. Add one identity-specific exchange only for a supported release and reuse an existing matching card, with verified UUID or explicit unresolved identity. Missing applicable method/activity/factor/identity blocks completeness; it is not a justified zero. Attribute raw activity/release totals and normalize once to the matched accepted reference output.	cp_phase1_environment_coverage	attributed native environmental quantities per matched final reference	review-ipcc-soils-2019

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
quality_identity	product and input rows	Declare species or cultivar, orchard block, lot, product formulation, and gate state; retain evidence gap flow identities as evidence gap rather than substituting a nearby flow.	lot record, supplier document, and review note
quality_measurement	mass, water, energy, and fuel rows	Use calibrated scales and meters where available; otherwise document the estimation method and uncertainty.	calibration record, meter check, or estimation worksheet
quality_temporal	all crop-year rows	Cover the complete represented orchard year and harvest campaign, including all harvest rounds and relevant applications.	crop calendar, application log, and harvest register
quality_completeness	input, output, and waste rows	Reconcile input records, accepted output, culls, residues, and packaging waste; explain missing records or material residuals.	mass-balance worksheet and waste receipts
quality_disclosure	dataset metadata	Disclose boundary gate, orchard age, allocation basis, water source, nutrient basis, crop-protection program, and identity evidence gaps.	dataset metadata and practitioner review

Preserve original activity records and all required qualifiers.	kg and native activity units	each accepted lot	matched production and handoff period	existing declared producer/primary gate	per declared reference flow	calibrated weighing, acceptance/grade records, lot chain, activation/bypass evidence and closed balances

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
calc_final_handoff_normalization	all foreground quantities and actual route outputs	Let R be positive measured accepted final mass in kg for one matched species/state/grade/gate/period, excluding tare, rejects, co-products and held stock. Physical ledger = raw physical quantity/R * 1000 kg, without burden-allocation scaling. Attributable inventory contribution = attributable raw quantity/R * 1000 kg, preserving native numerator units and the existing output/period attribution. A local intensity q_i=Q_i/O_i first reconstructs Q_i=q_iactual linked O_i; do not divide by R again after final normalization. Both handoff sides are the same measured event R/R1000 kg, not another physical yield. Include only actual active operations; record and substantiate bypass. Missing/nonpositive R or an unlinked terminal record blocks a normalized complete result, not zero. Preserve original stage data and cancel paired internal transfers once.	cp_declared_reference_handoff; original linked collection protocols	native quantities per declared final reference	declared-handoff-measurement-definition

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validate_mass_balance	harvest, conditioning, and gate output	Accepted product, culls, and recorded losses must reconcile to harvested fruit within the declared measurement tolerance; unexplained residuals require review.	mass-balance-identity
validate_input_records	orchard cultivation and conditioning	Every foreground quantity must identify the orchard block or facility, crop-year or campaign period, unit, collection protocol, and allocation basis when shared.	fao-gap-framework-2003; iso-14044-2006
validate_reference_qualifiers	reference flow and dataset metadata	The data package must declare species or cultivar group, geography, orchard age, production year, gate state, marketable grade, and identity evidence gap status before downstream use.	codex-fresh-produce-hygiene; usda-ams-citrus-standards

rule_id	Applies to	Rule	source_ids
validate_final_handoff_bypass	selected actual route and all conditional bypass states	Check both presence and absence of optional conditioning/packing/storage against actual records: exactly one required handoff reference persists, its source product/state/gate matches Section 3, active physical rows retain measured throughput, and inactive physical activities add no exchange. Require raw accepted mass, upstream closure, unique transfer pairing and single final normalization; an unexplained state or missing identity is not an assumed valid branch.	declared-handoff-measurement-definition

10. Published Dataset Profile

Field	Value
dataset_role	Foreground agricultural production dataset for fresh whole pomelos and grapefruits
downstream_use	May be used as a secondary dataset for orchard production and as a background dataset only when the declared gate, geography, year, and product state are compatible
allowed_use	Comparative or attributional modelling of fresh whole pomelo and grapefruit production through the declared farm-gate or pack-house gate
excluded_use	Juice, processed citrus, retail, consumer use, post-gate distribution, or any study that omits the required product, gate, crop-year, or residue qualifiers
required_metadata	species and cultivar group, geography, orchard block and age, crop-year, irrigation source, nutrient and protection basis, harvest campaign, marketable output, cull and waste fate, gate state, and identity evidence gap declarations
required_quality_disclosure	measurement basis, temporal coverage, allocation method, mass-balance result, water and nutrient accounting method, data gaps, and flow-identity status
update_trigger	New orchard route, irrigation or crop-protection technology, material change in yield or grade mix, revised nutrient or emission method, changed gate state, or resolution of an identity evidence gap

Evidence applicability: cited general farm-record and postharvest frameworks do not supply crop-specific yields, lifetimes, gate cutoffs or LCA allocation defaults. Those are this PCR methodology decisions; qualify them by the actual species, route and period and obtain compatible agronomic evidence before asserting completeness. Provisional author ranges are screening aids, not empirical acceptance limits or substituted measurements.
