Cabbages

1. Scope and Applicability

This PCR covers open-field or comparable soil-based production of fresh headed cabbages, from the declared planting material at the farm boundary through managed cultivation, harvest, trimming, field sorting, and hand-off of saleable fresh cabbage at the farm gate. Purchased planting material, fertilizers, crop-protection products, water, and energy enter as upstream product inputs. Nursery production before purchased planting material, protected cultivation with materially different infrastructure or climate control, off-farm packing, cold storage, distribution, processing, retail, cooking, and end-of-life are outside the default boundary unless explicitly added as separate processes.

The category includes headed cabbages represented by CPC 3.0 class 01212. It does not cover cauliflower, broccoli, kohlrabi, leafy greens classified outside 01212, fermented or otherwise processed cabbage products, or seed production.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_subdivide_first	Cultivation and harvest processes	Use process subdivision and mass reconciliation before allocation; do not allocate between an internal standing-crop hand-off and the same crop after harvest.	fao-horticultural-marketing
allocation_residue_classification	Outer leaves and rejected heads	Classify field-returned leaves as residues and off-site rejected heads by actual destination; do not treat either as an intended co-product unless evidence shows a deliberate product function and market hand-off.	ipcc-2019-managed-soils; fao-postharvest-loss-manual
allocation_intended_coproduct	Any additional revenue-bearing intended output	If subdivision cannot isolate an additional intended output, apply economic allocation using documented farm-gate revenues for the same reporting period and disclose prices, currency, period, and sensitivity.

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

Route-specific energy identification requirements

Select energy exchanges from the actual product state, operation, equipment and supply records. The conditional cards below are not a mandatory or exhaustive fuel list. For each requirement, document applicability and the used carrier, supplier, service period, native quantity and allocation; add a separate physically specific card and verify its UUID for any actual input not yet represented. An unidentified input remains an explicit completeness gap, never a zero or a generic energy exchange. Evidence of manual work, ambient drying or a bypass can justify non-use only for the affected operation. Preserve every required operation even when no example card is supplied.

Separate purchased supply from on-site conversion. Link self-generated electricity internally to the foreground generator and count its actual fuel and emissions there once; do not also charge a purchased-electricity supply for the same internal transfer. Likewise do not count supplier-side fuel again with purchased heat. Reconcile shared meters and contractor-included energy against existing cards, with one physical quantity assigned once. Retain source quantities, output throughput, shared-service allocation and excluded post-gate activities. For each carrier, apply period/output attribution once and scale to the declared reference quantity using matched accepted final output in the same product unit; do not normalize an already normalized amount again. Process-native intensities require a measured throughput link to that final output. These requirements do not set a consumption default or certify dataset completeness.

requirement_id	collection_protocol_id	Required operation and evidence
field_operation_energy_identification	cp_field_energy	Actual diesel tractor operations for tillage, planting, nutrient application, crop protection and field movement. Irrigation pumping is separately assessed from its actual prime mover and must not be silently assigned to diesel. Raw activity or stage basis: per ha planted cabbage crop per crop cycle. (route-energy-fao)

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.

Foreground records must retain each physical identity and formulated product separately. Calculate each active ingredient from formulated-product quantity and composition; do not aggregate unlike substances into one final exchange. This is a mandatory specific-input collection requirement, not a selected exchange. Identify every actual formulation, carrier or independently supplied service from primary records, with physical identity, state, native quantity and supplier specifications. Create a separate concrete card for each actual input before dataset completeness; verify a compatible UUID or explicitly retain its unresolved identity. Product mass and contained active-substance mass are different ledgers: convert only using documented composition and never count both as two purchases. Finished feed and separately added ingredients must not duplicate its recipe. Distinguish fuel purchase, purchased electricity/heat and inclusive machinery services; charge only their actual boundaries once. Preserve the original operation, period, attribution and final-output normalization.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
calc_nutrient_mass	Nutrient inputs	nutrient mass = formulated-product mass × declared nutrient mass fraction; retain N, P2O5, and K2O separately	product mass; composition	kg N; kg P2O5; kg K2O
calc_field_energy	Field-operation energy	carrier energy = measured carrier quantity × documented lower-heating-value or electricity conversion; sum only after retaining carrier identities	carrier quantity; conversion factor	MJ by carrier and total MJ
calc_land_occupation	Agricultural land occupation	occupied area-time = planted area × occupation days / 365.25	planted area; establishment date; harvest-completion date	m2*a
calc_mature_crop	Mature cabbage crop hand-off	gross mature crop = measured gross harvest or sampled mean head mass × harvested head count	gross mass or head-count sample records	kg wet mature crop	fao-horticultural-marketing
calc_harvest_mass_balance	Harvest outputs	incoming mature crop = saleable cabbage + outer leaves + rejected heads + documented uncollected loss, within declared uncertainty	all harvest output masses; uncollected loss estimate	reconciled kg wet mass and closure ratio	fao-postharvest-loss-manual
calc_managed_soil_n2o	Managed-soil nitrous oxide	Apply the declared IPCC direct and applicable indirect N2O equations to collected N inputs and residue pathways; prevent double counting of removed, burned, or field-returned residues.	N inputs; residue N; removal and burning fractions; leaching and volatilization parameters; selected factors	kg N2O-N per crop cycle	ipcc-2019-managed-soils
cabbage_planting_material_identity_and_fate	field_cultivation	For the original cabbage_planting_material 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_cultivation_inputs	Identity-specific exchanges and reconciled activity records
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_soil_emissions; species-specific activity ledger, method pathway and factor basis, matched accepted output	Identity-specific exchanges and reconciled activity records
