1. Scope and Applicability

This PCR guides foreground data-package construction for commercial fresh green peas (Pisum sativum L.) from crop establishment through crop management, harvest, optional primary conditioning, and hand-off at a declared farm gate or pack-house gate. It covers fresh garden peas sold in pods and fresh shelled green pea seeds when the product form, cultivar or type, maturity, grade, production route, and gate state are declared. Open-field and protected routes may be represented, but route-specific inputs and infrastructure must remain identifiable.

Seed production, nursery production, dry peas, pulses harvested after physiological maturity, frozen peas, canned or otherwise preserved peas, prepared meals, retail, consumer storage, and consumption are excluded. Washing, cooling, primary packaging, and purchased transport are included only when they occur before the declared gate. Multiple fields, plantings, or harvest rounds may be aggregated only after each crop cycle and product form is reconciled to accepted output.

Reference unit	kg
Required qualifiers	production geography; pea form (podded or shelled); pea type or cultivar group; open-field or protected route; seed status; planting date; harvest dates and rounds; crop-cycle basis; maturity and tenderness; colour and size or grade; irrigation and nutrient delivery method; crop-protection program; washing and cooling state; packaging state; declared gate; accepted, downgraded, rejected, and crop-residue fate

When constructing a foreground data package, all Required qualifiers must be declared in dataset metadata, process notes, the reference-flow comment, product description, or an equivalent data-package field. Missing qualifiers make the reference-flow definition incomplete. The reference product-flow identity is platform-verified for CPC 3.0:01242 and retained without a dataset version.

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.

Urea fertilizer (`crop_management_agricultural_nutrient_inputs_urea`)

Collection scope and applicability for crop_management_agricultural_nutrient_inputs. The following concrete identities have separate cards and apply only when use or generation is evidenced inside the original process scope. They are not mandatory inputs or a default recipe. Document non-use; missing records are not zero. Add a separate concrete card for any other actual material instead of substituting one of these names or UUIDs. Preserve attribution and boundaries and avoid double counting components included in outsourced services.

Collect each fertilizer product separately. Preserve each actual product identity, quantity, formulation, nutrient composition, application event, and allocation; do not count a compound product more than once. Raw activity or stage basis: per 1,000 kg accepted fresh green pea output.

Confirm identity, grade, state and unit from equipment, supplier and contemporaneous measurements; the product UUID does not establish actual use or upstream-provider compatibility. Count physical product mass once and retain moisture, N/P/K composition and application events; nutrient quantities are calculated attributes, not additional purchases of the same product. Give unlisted compound and organic fertilizers separate cards identified by formulation or feedstock.

Flow property / unit: Mass / kg NO3-
Amount rule: Record or calculate nitrate loss from documented N inputs, drainage, runoff, and receiving medium using one declared method.

The final exchange is kg NO3-. Keep species-specific elemental-N activity and any N-based factor/range in a separate calculation ledger. Convert that species-specific N mass by 62/14 exactly once before normalization; never reconvert compound mass or apply an N-based range directly to compound mass. A total nitrogen-loss pool is not this species without a supported split. Retain the actual receiving compartment and method boundaries; unknown identity or activity is not zero.

Final exchange mass is kg PO4; retain P-based activity, factors and screens in a separate ledger. Convert only the mass of P attributed to this chemical species by 95/31 exactly once, then normalize once to the accepted reference output. Do not treat total nutrient balance, soil retention or unexplained deficit as this release. Record each actual receiving compartment separately. Any gas-volume record requires its measured temperature, pressure and a supported mass conversion; it is not interchangeable with compound mass.

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_accepted_and_downgraded`	accepted peas, downgraded peas, shell residue, and rejects	Allocate shared crop-cycle inputs first to declared accepted green pea output using measured mass reconciliation. Report downgraded or rejected produce and shell residue separately; apply a co-product allocation only when a documented productive recipient exists.	`iso-14044-2006`; `unece-ffv-27-peas-2025`
`allocation_podded_and_shelled_forms`	podded and shelled green pea products	Keep podded and shelled forms separate when shelling changes the product boundary or output basis. If shared operations are aggregated, allocate them by measured mass or another declared physical relationship and retain form-specific evidence.	`iso-14044-2006`; `mass-balance-identity`
`allocation_multiple_cycles_or_types`	multiple plantings, cultivars, or harvest campaigns	Keep cycles and types separate when input regimes, route, grade, or gate differ. If aggregated, allocate shared operations by measured accepted mass or another declared physical basis.	`iso-14044-2006`
`allocation_reusable_packaging`	reusable crates, pallets, and containers	Allocate packaging burdens over documented reuse cycles and declared capacity or mass basis. Include return and loss records when attributable to the declared gate.	`iso-14044-2006`
`allocation_residue_use`	crop residue, shell residue, wash solids, and wastewater solids	Keep residue treatment and productive use separate from accepted product. Assign a credit only when recipient, intended use, substitution claim, and allocation method are documented.	`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.

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_crop_protection_records`	Operation crop_management: Crop-protection products cross the boundary when applied to the represented green pea crop. Original quantity method: Record product, active ingredient, formulation, concentration, application date, treated area, and application purpose from the crop-protection plan and application log.
`primary_crate_packaging_specific_input`	`cp_packaging_records`	Operation harvest_and_gate_preparation: Reusable crates, pallets, and other rigid transport or presentation containers are recorded when supplied or consumed before the declared gate. Original quantity method: Record container material, tare, capacity, count, reuse cycles, return, and loss; allocate the documented burden to the pea lot.
`primary_carton_packaging_specific_input`	`cp_packaging_records`	Operation harvest_and_gate_preparation: Cartons and boxes are recorded when used for the fresh pea lot before the declared gate. Original quantity method: Record material, package mass, capacity, count, and reuse or recycling state, then allocate to the pea lot by declared capacity or mass basis.
`primary_flexible_packaging_specific_input`	`cp_packaging_records`	Operation harvest_and_gate_preparation: Films, bags, liners, or other flexible primary packaging are recorded only when used before the declared gate. Original quantity method: Record film or bag material, mass, count, lot assignment, and recycling or loss state.

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.

`calc_crop_cycle_normalization`	all crop-cycle amounts	Normalized amount = recorded or calculated amount ÷ accepted green pea output × 1,000 kg. Preserve production-unit, crop-cycle, and product-form denominators.	recorded amount; accepted output	amount per 1,000 kg accepted green peas	`mass-balance-identity`
`calc_nutrient_emissions`	direct and indirect nutrient emissions	Apply one declared method to documented nutrient inputs, soil or substrate conditions, drainage or runoff, and residue fate; do not sum overlapping factors.	nutrient inputs; method factors; drainage; runoff; residue fate	emissions by substance and receiving medium	`ipcc-2019-managed-soils`
`calc_reusable_packaging`	reusable crates and pallets	Allocated packaging burden = item burden ÷ documented reuse cycles × pea-lot share by capacity or declared mass basis.	item mass; reuse cycles; lot capacity or mass; return and loss records	kg packaging allocated to pea lot	`iso-14044-2006`
`calc_transport_service`	purchased road freight	Transport service = loaded mass in tonnes × verified route distance in kilometres; report return or backhaul assumption separately.	shipment mass; route distance; service record	tonne-kilometres	`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_emission_records`; species-specific activity ledger, method pathway and factor basis, matched accepted output	Identity-specific exchanges and reconciled activity records

System boundary rules · 5

Rule ID	Applies to	Rule	Source IDs
`boundary_crop_cycle`	establishment and crop management	Include production-unit preparation attributable to the crop cycle, planting, crop management, supplied water, nutrients, crop protection, energy, and direct crop emissions. Disclose prior land use and exclude unrelated infrastructure construction.	unece-ffv-27-peas-2025
`boundary_route_specificity`	open-field and protected production	Keep route-specific infrastructure, pumping, heating or lighting, substrate, recirculation, drainage, and crop-termination records separate when they materially change the inventory.	ucdavis-edible-pod-peas-postharvest
`boundary_gate_preparation`	harvest, grading, shelling, washing, cooling, and packing	End the default foreground boundary at the declared farm-gate or pack-house gate. Include shelling, grading, washing, cooling, and primary packaging only when they occur before that gate.	unece-ffv-27-peas-2025, ucdavis-edible-pod-peas-postharvest
`boundary_nitrogen_emissions`	nutrient inputs, soil, drainage, and residues	Estimate applicable direct and indirect nitrogen emissions with one declared method using recorded nutrient inputs, drainage or leaching evidence, and residue fate. Avoid double counting pathways.	ipcc-2019-managed-soils
`boundary_residue_fate`	pod shells, rejected peas, crop residues, wash solids, and wastewater	Record field return, composting, feed use, treatment, transport, or disposal for each residue stream. A credit requires documented recipient, intended use, substitution claim, and allocation treatment.	iso-14044-2006

Allocation rules · 7

Rule ID	Applies to	Rule	Source IDs
`allocation_accepted_and_downgraded`	accepted peas, downgraded peas, shell residue, and rejects	Allocate shared crop-cycle inputs first to declared accepted green pea output using measured mass reconciliation. Report downgraded or rejected produce and shell residue separately; apply a co-product allocation only when a documented productive recipient exists.	iso-14044-2006, unece-ffv-27-peas-2025
`allocation_podded_and_shelled_forms`	podded and shelled green pea products	Keep podded and shelled forms separate when shelling changes the product boundary or output basis. If shared operations are aggregated, allocate them by measured mass or another declared physical relationship and retain form-specific evidence.	iso-14044-2006, mass-balance-identity
`allocation_multiple_cycles_or_types`	multiple plantings, cultivars, or harvest campaigns	Keep cycles and types separate when input regimes, route, grade, or gate differ. If aggregated, allocate shared operations by measured accepted mass or another declared physical basis.	iso-14044-2006
`allocation_reusable_packaging`	reusable crates, pallets, and containers	Allocate packaging burdens over documented reuse cycles and declared capacity or mass basis. Include return and loss records when attributable to the declared gate.	iso-14044-2006
`allocation_residue_use`	crop residue, shell residue, wash solids, and wastewater solids	Keep residue treatment and productive use separate from accepted product. Assign a credit only when recipient, intended use, substitution claim, and allocation method are documented.	iso-14044-2006
`allocation_rule_6`	foreground_burden_allocation	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.
`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
