Truffles, farmed

1. Scope and Applicability

This PCR covers fresh farmed truffles produced in a managed perennial or woodland-or-orchard symbiosis with inoculated host plants and delivered at the farm gate. The boundary distinguishes host establishment, managed stand production, harvest, and any conditional on-farm preparation needed to meet the declared fresh market state. It applies to rainfed or irrigated stands, single-site or aggregated sites, and production systems that use orchard, plantation, or managed woodland practices.

It excludes wild-collected truffles, nursery-only inoculated host plants sold as planting stock, host-plant timber or fruit products, truffle-derived processed foods, preservation, freezing, drying, packaging supplied after the farm gate, off-farm storage, transport, distribution, retail, and consumer use. A host crop or other product that is intentionally sold as a co-product is recorded separately and handled under the allocation rules in Section 7.

Reference unit	kg
Required qualifiers	truffle species or cultivar; host-plant species; production geography; stand age and establishment period; reporting period; harvested and accepted mass; maturity and grading; soil adherence or cleaning state; rejected and co-product destinations

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.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_fresh_mass	reference product and accepted fresh truffle outputs	Mass	kg	Report the as-received mass at the farm-gate hand-off. Record soil adherence, visible moisture, and grading state separately; do not silently convert fresh mass to dry mass.
perennial_stand_annualization	establishment and managed-stand inputs	Mass, volume, energy, or activity-specific property	activity-specific unit	Allocate stand-establishment and shared perennial inputs to the declared reporting period using documented stand age, productive period, replacement events, and output records. Do not apply a universal lifetime or yield.
nutrient_product_and_basis	fertilizer or soil-amendment input	Product mass and nutrient content	kg product and kg N, kg P2O5, or kg K2O as applicable	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.
area_to_reference_conversion	area-based establishment, management, and harvest records	Activity-specific property	ha and kg fresh truffle	Convert same-site, same-period totals by dividing by accepted fresh-truffle output before scaling to the 1 kg reference flow.

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

Apply the following rules in order:

1. allocation_single_primary_output: Treat accepted fresh farmed truffle as the primary output. Internal host-stand hand-offs and rejected material are not co-products.
2. allocation_avoid_subdivision: Subdivide establishment, stand management, harvest, and conditioning where a separate co-product or service has a distinct measured hand-off. Avoid allocation when a process can be directly assigned.
3. allocation_co_product_evidence: If host timber, fruit, prunings, nursery stock, or another product is intentionally sold or transferred as a co-product, declare its quantity, quality, destination, and hand-off evidence. Use a physical-causality allocation where a defensible relationship exists; otherwise use an explicitly justified economic allocation or another ISO 14044-consistent method.
4. allocation_residue_not_product: Treat unmarketed mortality, prunings, removed soil, rejects, and losses as waste or elementary flows according to destination unless evidence shows an intentional product or service hand-off.
5. allocation_period_consistency: Apply the same allocation choice across the complete declared stand period and reconcile it with replacement, mortality, and output records.

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
stand_machinery_fuel_input_specific_input	cp_stand_management_records	Operation truffle_stand_management: Record fuel for mowing, vegetation management, pruning, access, irrigation equipment, and other machinery that crosses the foreground boundary. Original quantity method: tank records, invoices, contractor records, or equipment activity converted with carrier identity retained

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.
