Peaches and nectarines

1. Scope and Applicability

This PCR covers cultivated peaches and nectarines (Prunus persica) from a bearing orchard through the declared farm-gate or first market hand-off as fresh, marketable fruit.

It includes orchard management, irrigation, nutrient and crop-protection applications, pruning and thinning, harvest, field handling, and on-site sorting, cooling, and packing before hand-off. Nursery production, orchard establishment, post-handoff transport, retail, consumer use, end-of-life treatment, and processed fruit are excluded by default.

Reference unit	kg
Required qualifiers	species; cultivar; fresh market state; harvest maturity; quality or market grade; production system; production geography; harvest year or crop cycle; declared hand-off; net product-mass basis; on-site sorting/cooling/packing status

When constructing a foreground package, all required qualifiers must be declared in dataset metadata, process notes, the reference-flow comment, the product description, or an equivalent field.

The sole reference output is reference_product_at_declared_handoff at declared_reference_handoff, a mandatory measurement of the actual accepted product at the already declared gate. Process onsite_sort_cool_pack remains conditional: omission of its physical activities does not remove this reference. Select the actual last included product handoff and record its process/output id; accept only the same species, physical state, grade, moisture basis and gate as Section 3. The prior marketable_fresh_fruit row is the measured output of its actual operation when active, not an additional final sale. No bypass creates processing, a yield assumption, an extra burden or a change of product boundary.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	reference product	Mass	kg	Normalize to net marketable fruit mass; exclude containers, culls, and waste fruit.
water_volume	irrigation and washing water	Volume	m3	Convert metered or documented water volume to m3.
nutrient_basis	fertilizer and amendments	Product mass and nutrient basis	kg product; kg N/P/K	Record actual product and declared or measured nutrient basis.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Bearing orchard block ready for the declared crop cycle
starting_condition_role	Fixes the annual foreground boundary; existing orchard capital and prior establishment are excluded unless annualized
product_classification_scope	Cultivated fresh peaches and nectarines from orchard production through the declared hand-off
recursive_input_rule	Do not recursively model same-category harvested fruit; a separate packing route records the upstream fruit dataset
upstream_dataset_requirement	Use linked background or secondary datasets for purchased inputs and resolve identity and geography
disclosure	Declare orchard age, productive area, species/cultivar, irrigation source, production system, crop cycle, yield, loss routes, and on-site conditioning

Boundary Rules

rule_id	Applies to	Rule	source_ids
boundary_starting_condition	orchard production	Include the attributable orchard establishment, nursery-stock supply, immature years, replacement and termination contribution as well as the bearing-year crop cycle. Use the documented benefiting productive-life output basis: for each native activity pool E, year y receives E*Q_y/sum(Q_y) over the evidenced completed cohort life or site-specific actual-plus-forecast trajectory; do not pool unlike numerator units. Add directly measured bearing-year operations once, then apply Section 7 and final normalization. Missing history or a nonpositive/unknown lifetime output denominator blocks completeness, not permission to exclude establishment. Supplier-covered nursery production is linked once; no invented universal lifetime.	source_ucanr_peach_nectarine_cultural; source_iso_14044
boundary_management_and_harvest	orchard and harvest	Include crop management, irrigation, nutrient and crop protection, pruning/thinning, harvest, and field handling.	source_ucanr_peach_nectarine_cultural; source_ucanr_peach_fertilizer
boundary_optional_packhouse	on-site conditioning	Include on-site sorting, cooling, and packing only when before hand-off; otherwise disclose downstream.	source_usda_ams_fresh_fruit_grades

Urea fertilizer (orchard_management_agricultural_nutrient_inputs_urea)

Collection scope and applicability for orchard_management_agricultural_nutrient_inputs. The following concrete identities have separate cards and apply only when use or generation is evidenced inside the original process scope. They are not mandatory inputs or a default recipe. Document non-use; missing records are not zero. Add a separate concrete card for any other actual material instead of substituting one of these names or UUIDs. Preserve attribution and boundaries and avoid double counting components included in outsourced services.

Collect each fertilizer product separately. Preserve each actual product identity, quantity, formulation, nutrient composition, application event, and allocation; do not count a compound product more than once. Raw activity or stage basis: per 1 kg net marketable fruit output.

Record the measured accepted output of onsite_sort_cool_pack only when that operation actually occurs. Preserve species, condition, grade, moisture, lot and its real outgoing gate. This stable row id identifies an actual route output; the sole final reference is reference_product_at_declared_handoff. Retain raw output and link the selected final lot without counting it as another final product. Any UUID shown is usable only for its independently confirmed physical state/gate; an incompatible upstream/intermediate state needs a separately verified or explicit unresolved identity.

Process: Accepted-product measurement at declared handoff (declared_reference_handoff)

This measurement adds no processing, waste generation or emission. Preserve all real upstream operations and losses; bypass only operations demonstrated absent.

Measure only accepted product at the existing declared gate. Match one actual terminal source record; internal paired transfer and this reference represent the same event, not two sales. Verify identity for the actual species/state/gate independently; an identifier confirmed only for fresh farm-gate goods cannot represent an incompatible conditioned or independent pack-house state. Missing identity remains explicit and is not resolved by copying an adjacent output UUID.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_subdivision	separable blocks, species, cultivars, or runs	Avoid allocation by separately measuring peach and nectarine activities whenever records permit.	source_iso_14044
allocation_shared_crop_output	jointly managed outputs	If subdivision is impossible, allocate by documented net marketable mass and disclose mix, basis, and sensitivity.	source_iso_14044
allocation_residue_route	culls, residues, and diverted fruit	Treat culls and residues as waste unless a separate product hand-off is documented; do not apply an automatic avoided-burden credit.	source_iso_14044

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.

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

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
calc_final_handoff_normalization	all foreground quantities and actual route outputs	Let R be positive measured accepted final mass in kg for one matched species/state/grade/gate/period, excluding tare, rejects, co-products and held stock. Physical ledger = raw physical quantity/R * 1 kg, without burden-allocation scaling. Attributable inventory contribution = attributable raw quantity/R * 1 kg, preserving native numerator units and the existing output/period attribution. A local intensity q_i=Q_i/O_i first reconstructs Q_i=q_iactual linked O_i; do not divide by R again after final normalization. Both handoff sides are the same measured event R/R1 kg, not another physical yield. Include only actual active operations; record and substantiate bypass. Missing/nonpositive R or an unlinked terminal record blocks a normalized complete result, not zero. Preserve original stage data and cancel paired internal transfers once.	cp_declared_reference_handoff; original linked collection protocols	native quantities per declared final reference	declared-handoff-measurement-definition

rule_id	Applies to	Rule	source_ids
validate_final_handoff_bypass	selected actual route and all conditional bypass states	Check both presence and absence of optional conditioning/packing/storage against actual records: exactly one required handoff reference persists, its source product/state/gate matches Section 3, active physical rows retain measured throughput, and inactive physical activities add no exchange. Require raw accepted mass, upstream closure, unique transfer pairing and single final normalization; an unexplained state or missing identity is not an assumed valid branch.	declared-handoff-measurement-definition
