Cantaloupes and other melons

1. Scope and Applicability

This PCR covers commercial production of fresh, whole, unprocessed cantaloupes and other melons from field preparation or protected-crop establishment through managed cultivation, harvest, grading, optional on-farm conditioning, and farm-gate hand-off. It covers cantaloupe, muskmelon, honeydew, Galia, Persian, casaba, and other non-watermelon melons when the cultivar and market state are declared. It applies to seeded and transplanted annual production under irrigated or rainfed management. It excludes watermelon, melon seed or transplants sold as planting material, preserved or cut melon, juice, drying, cold storage after farm-gate transfer, distribution, retail, and consumption.

Required qualifiers	cultivar or melon type; production geography; production year and crop cycle; seeded or transplanted route; irrigated or rainfed regime; fruit maturity and harvest window; size and grade criteria; whole or damaged state; washed or unwashed; packaging state; farm-gate hand-off

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. Missing required qualifiers make the reference flow definition incomplete for that data package.

Each foreground dataset must explicitly select one actual route, declared gate, product state and output row. Reconcile the selected terminal route with reference_product_at_declared_handoff; normalize that handoff output to the reference quantity and retain preceding-stage outputs as measured transfers. Raw weighing, mass reconciliation and lot traceability requirements continue to apply.

The sole reference output is reference_product_at_declared_handoff, receiving the selected actual route product at the declared gate. Existing route-output ids identify the source and physical state; they are no longer individually fixed to the reference quantity.

Process: Product Measurement at the Declared Handoff (declared_reference_handoff)

This node records the actual product handoff at the existing system boundary for reconciliation and reference-quantity normalization. It adds no physical processing and does not presume drying, cooling, storage, packaging or transport. Each data package declares one actual route, one terminal product state, moisture or dry-matter basis, and gate. Feed only the accepted product delivered by that route at that gate into this node; do not add other routes as extra inputs. Record co-products separately and apply Section 7. Count preceding inputs, losses and emissions once. Normalize using the measured accepted net mass at the handoff; this measurement node changes neither mass, yield nor allocation.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_avoid_by_subdivision	field management, harvest, and conditioning	Prefer separate records for production, harvest, conditioning, marketable fruit, residues, and waste before applying allocation.	iso-14044-2006
allocation_melon_grades	multiple marketable melon grades	Treat declared grades as one reference-product category when they share the same intended use; report grade-specific quantities and use economic or mass allocation only when separate modelling is infeasible.	iso-14044-2006
allocation_residue_and_rejects	residues, rejects, and useful secondary outputs	Treat material with a declared useful hand-off as a co-product only when the hand-off and destination are documented; otherwise record it as waste or residue with fate disclosed.	fao-postharvest-handling-ae075e; iso-14044-2006
allocation_shared_operations	shared field, protected-crop, or conditioning operations	Allocate shared operations by measured area, time, mass, or another documented physical relationship; disclose the choice and test a value-based sensitivity when the physical relationship is not representative.	iso-14044-2006

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.

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
melon_field_fuel_input_specific_input	cp_melon_field_operation_records	Operation melon_crop_management: Record fuel consumed by field preparation, crop care, and harvest machinery when the fuel crosses the foreground boundary. Original quantity method: Tank records, invoices, or contractor activity converted to a declared carrier basis.
melon_crop_protection_input_specific_input	cp_melon_crop_protection_records	Operation melon_crop_management: Record each herbicide, insecticide, fungicide, and other formulation separately by product and application event. Do not merge distinct formulations into one identity. Original quantity method: Sum measured formulation mass by product, production unit, and application event.

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

calc_area_to_reference_flow	field and crop-management flows	Crop-cycle amount per hectare divided by same-cycle marketable melon yield per hectare, multiplied by 1,000 kg	flow amount; production-unit area; marketable melon mass	amount per 1,000 kg marketable melon
calc_nutrient_content	fertilizer and amendment inputs	Product mass multiplied by documented nutrient fraction; preserve product and nutrient or oxide-equivalent basis	product identity; mass; assay; reporting basis	kg N, kg P2O5, or kg K2O by source

calc_conditioning_mass_balance	on-farm conditioning	Incoming batch mass equals accepted fruit plus useful outputs, rejects, and measured losses within uncertainty	batch masses; moisture; loss records	reconciled conditioning outputs per accepted fruit	mass-balance-identity
melon_planting_material_input_identity_and_fate	melon_field_establishment	For the original melon_planting_material_input collection role at this operation, identify the actual physical form, species/material, composition, state and supply/treatment boundary before creating exchanges. Each seed lot, transplant, crown, cutting, larval stage, formulation, coating, preservative or separated residue actually used/generated requires its own concrete card where relevant to this role; these examples are alternatives, not a required recipe. Retain existing collection records and route-specific source evidence. Count-based planting records require measured or supplier-supported mass-per-unit when matched to a mass-based provider; retain count and mass as linked attributes rather than two purchases. Do not merge separate husk/shell or separate agents. A real mixed stream requires composition and recipient evidence and is counted once. Before completeness, record every applicable amount and native unit, link a compatible verified UUID or explicitly unresolved identity, preserve stock/return attribution, and normalize the attributable raw quantity once to the accepted reference output. Missing records are not zero; aggregate ranges are not individual-input defaults.	cp_melon_establishment_records	Identity-specific exchanges and reconciled activity records	fao-gap-framework-2003
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_melon_emission_activity; species-specific activity ledger, method pathway and factor basis, matched accepted output	Identity-specific exchanges and reconciled activity records

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.
