Lemons and limes

1. Scope and Applicability

This PCR covers fresh, unprocessed lemons and limes from orchard establishment or the declared productive orchard cycle through cultivation, harvest, optional primary grading, washing or waxing, and hand-off at the declared farm-gate or pack-house gate. It includes orchard inputs, irrigation, crop protection, harvest, primary packaging, and documented residue or reject routing before the gate. It excludes nursery production, processed citrus, retail, consumers, downstream transport, unrelated land conversion, and infrastructure construction. The data package shall declare species, cultivar, geography, orchard age, crop cycle, gate, maturity, grade, handling state, and residue fate.

Use a compatible verified UUID or explicit unresolved identity; wastewater volume is not pollutant mass and missing effluent composition is a completeness gap. Link inclusive treatment services once, with no duplicate outgoing transfer and same downstream treatment burden.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_shared_orchard_cycles	establishment and multiple cycles	Allocate shared orchard burdens by documented area-time, tree-year or another justified physical basis and disclose the basis.	fao-gap-framework-2003
allocation_marketable_and_reject_outputs	harvest and gate handling	Treat marketable fruit as reference output; record downgraded fruit, culls, trim and recovered material separately, and allocate only where a genuine co-product function exists.	fao-postharvest-handling-ae075e; globalgap-ifa-fruit-vegetables-v6
allocation_recovered_residue_claim	recovered residues	Do not claim avoided production unless destination, function, quantity and receiving-system evidence are documented.	fao-gap-framework-2003

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
orchard_fuel_input_specific_input	cp_energy_and_fuel_records	Operation managed_citrus_orchard_cycle: Fuel used by tractors, sprayers and harvest equipment crosses the boundary when consumed. Original quantity method: Fuel issue records, tank measurements or invoices allocated to orchard work.
crop_protection_input_specific_input	cp_crop_protection_records	Operation managed_citrus_orchard_cycle: Crop-protection products cross the boundary when purchased or issued for orchard management. Original quantity method: Record formulated product, active substance when available, date and treated area.
primary_packaging_input_specific_input	cp_conditioning_and_packaging_records	Operation citrus_harvest_and_gate_handling: Crates, cartons, bags or other primary packaging are included when used before the declared gate. Original quantity method: Record material and quantity by packaging lot and allocate to packed output.

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_cycle_normalization	all process rows	normalized amount = recorded amount / marketable gate output * 1,000 kg.	block records; dates; gate output	normalized amount	fao-gap-framework-2003
calc_nutrient_basis	fertilizer and amendment rows	Keep product mass and N, P2O5 and K2O mass separate; calculate only from declared evidence.	product mass; nutrient fractions or result	product and nutrient amount	globalgap-ifa-fruit-vegetables-v6
calc_soil_emissions	soil emission rows	Apply one selected IPCC-compatible nitrogen method to documented inputs and disclose factors and conversions.	N input; factors; qualifiers	elementary-flow amount	ipcc-2019-refinement-afolu
calc_mass_reconciliation	harvest and gate rows	Reconcile harvest, marketable output, rejects, residues, wastewater and documented loss.	lot records; scale; water balance	mass balance	fao-postharvest-handling-ae075e
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_amendment_records; species-specific activity ledger, method pathway and factor basis, matched accepted output	Identity-specific exchanges and reconciled activity records

quality_temporal_completeness	full cycle	Cover all harvests and applications and identify missing months, blocks or lots.	cycle completeness checklist

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.
