Flower seeds

1. Scope and Applicability

This PCR covers seed of flowering plants produced and released specifically for sowing. It follows one declared species, cultivar and lot from parent stock and managed multiplication through harvest, extraction, drying, cleaning, testing, optional treatment and packaging at the seed producer or conditioner hand-off.

It excludes cut flowers, bulbs and other vegetative propagules, edible or oilseed uses, unmanaged wild collection, and seed without a declared sowing use. A dataset shall not combine unlike species, cultivars, production routes, or treated and untreated states without transparent weighting.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_mass_reconciliation	each process	Reconcile opening stock, inputs, outputs, moisture change, residues, rejects and closing stock on one basis.
allocation_secondary_outputs	saleable plant material or downgraded seed	Prefer subdivision or direct physical attribution; if allocation remains, disclose outputs, causal basis, formula and sensitivity.
allocation_rejects	all rejects	Do not include rejected seed in released output or credit a destination before routing is evidenced.
allocation_periods	perennial crops and shared assets	Attribute establishment and infrastructure over documented productive output using one consistent period rule.
allocation_batches	shared processing, storage and changeovers	Assign shared burdens by measured time, occupied storage, throughput or another causal driver without double counting.

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_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
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
