Other sugar crops n.e.c.

1. Scope and Applicability

This PCR covers farm-produced sugar maple sap, sweet-purpose sorghum stalks, and stevia leaves at one declared crop-specific harvest or primary-conditioning hand-off. A dataset shall select exactly one species, plant part, intended crop purpose, market state, and hand-off. The three alternatives share a mass-based reference amount only; their exchanges, yields, routes, and environmental burdens shall never be aggregated into one inventory.

Include establishment and management attributable to the declared production period, field or sugarbush operations, harvest or sap collection, and only the primary conditioning needed to reach the declared hand-off. For stevia, declare fresh or dried leaves; this PCR's worked route and ranges use dried leaves. Exclude sugar or sweetener extraction, maple syrup concentration, sorghum juice extraction or fermentation, steviol-glycoside extraction/refinement, and all later manufacture. A different species or product state needs its own foreground record and evidence.

market_state	Unprocessed sap, harvested stalk, or harvested/primary-conditioned leaf, at a declared hand-off and moisture state

3. Reference Flow

Field	Value
What	One crop-specific raw output: sugar maple sap, sweet-purpose sorghum stalk, or stevia leaf; select one only
How much	1 kg of the selected output at its declared hand-off; retain the crop, plant part, moisture, and market-state qualifiers
How well	Identify species/cultivar where known, crop purpose, harvest or tapping method, moisture/state, grade, and destination
How long or cycle	One declared tap season for maple; one crop cycle for sorghum; one harvest cycle or declared multi-cut season for stevia
reference_flow_link	reference_product_at_declared_handoff

Field	Value
Reference amount	1
Reference product flow	Route-specific harvested product listed above; UUID unresolved
Reference flow property	Mass 93a60a56-a3c8-11da-a746-0800200b9a66
Reference unit group	Units of mass 93a60a57-a4c8-11da-a746-0800200c9a66
Reference unit	kg
Required qualifiers	Exactly one crop branch; species/cultivar; plant part; intended sugar-crop purpose; fresh/dried state and moisture; geography; production period; crop-specific hand-off; grade; allocation and multi-period treatment

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

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

Inventory one crop branch only. If one stand or field produces multiple intended products in the declared period, first test subdivision by field, operation, harvest, or lot. If subdivision is not feasible, choose and justify a physical or economic allocation driver consistent with the question, document all products and hand-offs, and test a material alternative. Maple timber, sorghum grain, and stevia stems are co-products only when they are intentionally harvested and leave the process as useful products. Leaves, tops, roots, weeds, rejected material, sap leakage, and field losses are residues or waste unless a real use and hand-off are documented. Record multi-year assets and shared equipment once, allocate them by measured productive area, use, tap-season, or machine time, and prevent duplicate attribution across periods or outputs.

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

Inventory completeness: conditional named cards are examples of individual exchanges, not an exhaustive recipe or a requirement to use those products. Before completing a foreground package, enumerate every actual planting stock, nutrient, crop-protection formulation, asset material, operating service, carrier, packaging material, waste stream and applicable elementary substance separately, using its physical identity, state, native property/unit, origin or receiving compartment, and measured or method-calculated quantity. Missing identity or quantity remains a completeness gap, never an assumed zero. Preserve the actual lot and phase basis; do not sum intermediate transfers as additional final output or duplicate burdens included in purchased services.

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.

Environmental Coverage Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
calc_managed_land_coverage	actual managed-production nodes	For each actual owned managed-production site, collect the occupied area and dated occupation intervals, including attributable establishment/immature and production periods. Occupation is area multiplied by actual duration, converted explicitly to the selected area-time unit (1 ha = 10,000 m2; time in years); hectares per crop-cycle alone are not an area-time result without duration. Partition or take the union of overlapping establishment/management intervals so the same area-time is counted once, with shares across actual co-users summing to one. Record evidenced land transformation separately by actual from/to land class, event area and date under the declared land-use method; transformation has area units and is not added to occupation. Planting, continued occupation or missing prior-land data do not establish a transformation or zero transformation. Preserve actual historical-event attribution and carbon-stock/emission method coverage where applicable; no invented land conversion or generic carbon credit. Instantiate separate compatible elementary identities with verified UUIDs or explicit unresolved identities; attribute once and normalize to the matched final reference. Purchased completed biological inputs inherit compatible upstream land coverage once instead of duplicating it locally. Missing applicable land identity, area, duration or prior-state evidence remains a completeness gap; documented no transformation is a valid absence.	cp_phase1_environment_coverage	attributed native environmental quantities per matched final reference
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

9. Validation Rules

• validate_single_branch: Exactly one route, species, plant part, intended purpose, product state, and hand-off are present for each dataset.
• validate_reference_identity: Keep the reference product UUID blank until an exact raw product identity and mass property/unit group are confirmed; never use grain, syrup, sugar, or extracted sweetener as a proxy.
• validate_process_chain: Match the selected route to its establishment/management, harvest or tapping, and declared primary-conditioning records; omit downstream extraction and manufacture.
• validate_mass_and_moisture: Reconcile harvested or collected mass, fresh/dry mass, moisture, losses, rejects, and coproducts; no double counting.
• validate_uuid_resolution: Before a final generated exchange, expand each parameterized card from actual records and verify a concrete compatible UUID, property, and unit. Resolve uncovered inputs and outputs independently; retain unresolved identities in this candidate.
• validate_period_allocation: Reconcile establishment, production, replacements, repeated cuts/tapping, and termination; prevent an asset or field burden from being attributed twice.
• validate_coproduct_and_reject: Trace each intended coproduct, downgraded product, rework, residue, and waste to one destination; rejected material is not accepted reference output.
• validate_extraction_exclusion: Reject syrup concentration, sorghum juice/sweetener extraction or fermentation, and steviol-glycoside extraction/refinement from the declared boundary.
• validate_range_and_quality: Check every card range, unit, basis, source scope, and foreground value; investigate exceedances without treating provisional ranges as conformance limits.
