Green garlic

1. Scope and Applicability

This PCR guides a foreground data package for fresh, whole green garlic harvested while the plant remains in its immature, green state. It covers open-field and protected cultivation of garlic grown for fresh sale as a bundle, bunch, loose whole plant, or trimmed whole plant, from the declared prepared field or protected unit through harvest, optional sorting, washing, cooling, primary packing, and the declared farm-gate or pack-house hand-off. The crop cycle includes planting material, soil and crop management, irrigation, crop protection, harvest, and all lifting or pulling operations attributed to the planting.

Dry mature garlic bulbs, garlic seed production, peeled or cut garlic, dehydrated, frozen, pickled, cooked, milled, or otherwise processed garlic, retail and consumer operations, durable farm infrastructure, machinery manufacture, land-use change, and transport after the declared gate are outside the default scope. A protected route, irrigation installation, or post-harvest service may be included when it occurs before the declared gate and its attribution is documented. Field residues, undersized or damaged plants, wash water, packaging, and other rejects remain in the foreground until their fate or hand-off is recorded.

Reference product flow	Green garlic 7fe025ea-1677-454e-8a33-4ff5df4833bd
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	variety or cultivar group; production geography; open-field or protected route; planting material type and source; planting date and density; harvest or lifting dates and rounds; maturity, bulb and leaf condition, trimming, grade, and defect criteria; irrigated or rain-fed status; actually applied fertilizer or soil-amendment products and nutrient basis; crop-protection program; washing and cooling state; primary packaging state; residue, reject, wastewater, and packaging fate; and declared gate

The reference product remains a semantic green-garlic output until the foreground data package resolves its platform flow, flow property, and unit group. No nearby mature-garlic or leek identity should be substituted for this category.

When constructing a foreground data package, every item in Required qualifiers must be declared in dataset metadata, process notes, the reference-flow comment, the product description, or an equivalent data package field. Missing qualifiers make the reference-flow definition incomplete.

This reference UUID denotes the fresh, unprocessed farm-gate product. Verify actual species, product state and handoff before applying the binding. An independent pack-house, further-processed or otherwise incompatible output requires separately verified identity and must not inherit this UUID. Identity verification does not change the actual system boundary or quantity-normalization requirements of this PCR.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids

allocation_shared_inputs	shared irrigation, electricity, machinery, storage, and packing loads	Allocate a shared input using the most physically causal documented driver, such as measured mass, area-time, operating time, or container count. Report the driver and residual unallocated amount.	iso-14044-2006
allocation_co_products	downgraded green garlic, feed, compost, or other recipient-bound outputs	Treat downgraded or recovered material as waste unless a documented recipient, intended use, quality, and hand-off demonstrate a co-product function. If allocation is required, use the stated physical driver first and disclose the alternative scenario.	iso-14044-2006; mass-balance-identity

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

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_management_records	Operation crop_management: Record each crop-protection product applied to the green-garlic crop, including active ingredient or product name, concentration, application date, treated area, application method, and pre-harvest interval where applicable. Original quantity method: Sum product quantities from application logs and supplier records for the declared crop cycle; retain product identity and active-ingredient concentration separately.
primary_container_packaging_specific_input	cp_gate_handling_records	Operation harvest_and_gate_preparation: Record crates, bins, cartons, or other primary containers that cross the foreground boundary with the green garlic. State whether each container is single-use, returnable, or reused and record the declared allocation of reusable packaging. Original quantity method: Record packaging material mass or container count, tare, reuse cycles, and the allocation basis for reusable containers.

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.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
calc_output_normalization	all process inputs and outputs	Normalize each crop-cycle quantity as recorded quantity / measured marketable green-garlic output * 1,000 kg. Keep the unnormalized record for audit.	field or facility record; marketable output	PCR-normalized amount	mass-balance-identity
calc_nutrient_basis	fertilizer_soil_amendment_input	For each actually applied product, calculate nutrient mass as product mass * documented nutrient fraction; retain product mass and each nutrient equivalent as separate fields.	product mass; supplier or laboratory nutrient concentration	kg product and kg nutrient	fao-good-agricultural-practices
calc_area_time	land_occupation_establishment; land_occupation_management	Calculate area-time as occupied area * declared occupation duration, then attribute it to the crop-cycle output.	area; occupation dates	ha*a	mass-balance-identity
calc_soil_nitrogen_emissions	soil_nitrous_oxide_emission; soil_ammonia_emission; soil_nitrate_leaching	Apply the selected measured or factor-based nitrogen method to documented nitrogen inputs, organic additions, irrigation, soil, and drainage evidence. Record direct, indirect, or leaching components separately when supported.	nutrient basis; soil and drainage records; selected factor or model	declared pollutant amount	ipcc-2019-refinement-managed-soils
calc_harvest_mass_balance	marketable_green_garlic_output; harvest_reject_waste; crop_residue_output	Reconcile gross harvested mass to marketable output, downgraded or rejected mass, field residue, trimming, and measured loss. Investigate any unexplained residual before normalization.	harvest tickets; grade sheets; residue and loss records	reconciled output and waste streams	mass-balance-identity
calc_wash_wastewater	wash_water_input; gate_wastewater	Use one defined process control volume and matched period in water-mass units. Discharged water = external supplied water + water in incoming product/material + other actual external water inflows + opening water stock - water in all outgoing products/residues - actual evaporation - water in separately exported streams - closing water stock. Convert measured volumes only with a compatible documented density. Internal recirculation remains within that boundary and cancels; do not subtract it again from fresh-water inflow. A genuinely external reclaimed-water receipt is an external inflow. Retain liquid discharge separately from its dry solids/pollutant masses. Prefer measured discharge and use the balance as reconciliation; missing components or unexplained residuals are gaps, not automatic wastewater, evaporation or zero.	wash-water meter; discharge meter; retained-water or loss record	wastewater volume or mass	mass-balance-identity; codex-cxc-53-2003-fresh-produce
calc_transport_service	pre_gate_transport_input	Calculate tonne-kilometres as transported mass in tonnes * documented one-way distance in kilometres; disclose shared loads and empty-return treatment.	shipment mass; route distance; load and return record	t*km	codex-cxc-53-2003-fresh-produce
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_emission_inputs; species-specific activity ledger, method pathway and factor basis, matched accepted output	Identity-specific exchanges and reconciled activity records
