Chick peas, dry

1. Scope and Applicability

This PCR applies to mature, dry, unprocessed chickpea grain (Cicer arietinum), including desi and kabuli market classes, at the farm gate. It covers managed field production, harvest and threshing, farm cleaning and grading, and conditional aeration or drying needed to reach the declared farm-gate state.

Green or succulent chickpeas, planting seed sold as seed, flour, split or dehulled fractions, canned or cooked products, and downstream industrial cleaning, sizing, milling, fractionation or food manufacture are outside scope. The foreground package must declare geography, crop year, market class, production route, harvest route, moisture basis, grade or destination specification, and whether conditional stabilization occurred.

2. Product Category Identity

Field	Value
canonical_pcr_id	pcr.agriculture-forestry-and-fishery-products.products-of-agriculture-horticulture-and-market-gardening.chick-peas-dry
classification_refs	CPC 3.0 01703 Chick peas, dry; mapping relation: narrower
covered_products	Mature dry desi and kabuli chickpea grain at farm gate, unprocessed beyond farm cleaning, grading and necessary stabilization
excluded_products	Green chickpeas; planting seed sold as seed; sprouts; flour; splits; dehulled fractions; canned or cooked products; downstream industrial cleaning, sizing or processing
representative_product	Mature dry chickpea grain, desi or kabuli, meeting a declared farm-gate moisture and grade or destination specification
production_route	Managed field production followed by distinct harvest/threshing and farm conditioning; rainfed and irrigated production may coexist across fields, while straight cutting and swathing are mutually exclusive for the same harvest event; ambient aeration and supplemental low-temperature drying may coexist sequentially for a lot
market_state	Harvested grain, unprocessed; accepted at farm gate after declared cleaning, grading and any required stabilization

The managed biological production parent is field_production. Route deltas must be evidenced by changed inventory categories or records: irrigated fields add supplied-water and pumping records; swathing adds a separate cutting/windrow event; direct combining omits that event; heated drying adds fuel or heat and temperature records. A label alone does not establish a distinct route.

3. Reference Flow

Field	Value
What	Mature dry chickpea grain at the farm gate
How much	1,000 kg as-received mass at the declared moisture content
How well	Desi or kabuli class; declared grade or destination specification; declared moisture; accepted grain excludes unresolved rework, foreign material, unrecovered loss and downgraded output
How long or cycle	One crop cycle, with post-harvest operations linked to the harvested field and lot
reference_flow_link	reference_product_at_declared_handoff

Field	Value
Reference amount	1000
Reference product flow	Chick peas, dry
Reference flow property	Mass 93a60a56-a3c8-11da-a746-0800200b9a66
Reference unit group	Mass unit group 93a60a57-a4c8-11da-a746-0800200c9a66
Reference unit	kg
Required qualifiers	desi or kabuli class; cultivar where material; geography; crop year; rainfed or irrigated route; straight-cut or swathed harvest; moisture percentage and wet or dry basis; grade or destination specification; farm-gate hand-off; drying or aeration route; allocation choice

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

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	accepted reference product	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Measure as-received mass and state moisture percentage and basis; any conversion to a common moisture uses recorded inlet and outlet moisture and conserves dry matter.
nutrient_products	consolidated agricultural nutrient input	Product quantity and nutrient composition	kg or m3 product and kg N, P or P2O5, K or K2O as applicable	Record every actual product once; retain formulation and nutrient analysis so compound and organic products are not duplicated across product-mass and nutrient-mass reports.
grade_fraction	damage, green seed, foreign material, rework and rejects	Mass fraction	kg/kg or % by mass	Use a representative lot sample and state whether the denominator is incoming bulk grain or cleaned sample.
moisture_balance	drying and aeration	Mass and moisture fraction	kg and % wet basis unless declared otherwise	Reconcile inlet dry matter, outlet dry matter, water removed, downgraded grain and rejects for each lot.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	A declared field prepared for the chickpea crop cycle, with prior land use, soil condition, preceding crop and seed origin identified
starting_condition_role	Starting condition for managed biological production; burdens of purchased seed, products, energy and services enter through upstream datasets
product_classification_scope	Mature dry chickpea grain represented by CPC 3.0 01703; green chickpeas, seed commodities and processed fractions remain outside this product category
recursive_input_rule	Chickpea grain retained as planting seed is recorded as a seed input from a preceding crop or external supplier and is not recursively modelled as the current crop's reference output
upstream_dataset_requirement	Use geographically and technologically appropriate upstream datasets for concrete seed, nutrient products, crop-protection products, water supply, energy carriers and contracted services

Water removed from grain to air (removed_moisture)

Calculate water removed from measured inlet and outlet masses and moisture fractions. Do not treat this water as product yield or unexplained mass loss.

• Selected flow: Water to air

• Flow property / unit: Mass / kg

• Amount rule: Determine supported evaporation on a closed water-mass control volume: incoming material water + actual added water + opening water stock - water in all accepted/co-product/reject/residue exits - separate liquid discharge/exports - closing water stock. Use measured wet mass times wet-basis moisture for each material stream, and compatible density for liquid volumes. Internal recirculation cancels. Retain actual rain/rewetting where relevant; total fresh/dry mass difference is not all water. Independently support all terms and the evaporation pathway; investigate an unexplained or negative balance rather than force it into a vapour release or clip it to zero. Keep water quantities distinct from dry-solids loss and other volatiles. Attribute and normalize the evidenced water release once using the original matched final reference.

For the stated no-dry-matter-loss case, incoming mass = 1000 × (1 − 0.14)/(1 − w_in), with w_in between 0.14 and 0.18; water removed = incoming mass − 1000. Upper bounds are rounded upward to 0.001 kg. Actual dry-matter rejects, added water or other inlet moisture require a new lot balance, not these limits.

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

rule_id	Applies to	Rule	source_ids
allocation_subdivision_first	all multi-output nodes	Subdivide directly measured field, harvest, conditioning and stabilization operations before allocation. Assign lot-specific rework and reject burdens to the producing lot.	iso-14044-allocation
allocation_residue_status	straw, pods and downgraded grain	Classify a flow as an intended co-product only when deliberate collection, a documented destination and an economic or physical function are demonstrated. Field-returned biomass, shatter and discarded rejects are residues or losses and receive no product credit.	iso-14044-allocation; saskatchewan-chickpea-harvest
allocation_remaining_burdens	chickpea grain and intended co-products	When subdivision cannot resolve shared burdens, apply one declared allocation method consistently to all intended outputs. Prefer documented economic allocation at the first independent hand-off; report quantities, prices, reference period and sensitivity to a mass allocation.	iso-14044-allocation
allocation_run_integrity	batches, campaigns and rework loops	Assign shared cleaning, start-up and changeover burdens once across affected lots; a rework pass retains its burdens and material linkage, and rejected material is never counted as accepted output. This is single-period attribution and shared burdens do not cross the crop-cycle boundary.	mass-balance-identity

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.

Calculation Rules

calc_allocation	intended multi-output nodes	allocate only residual shared burdens after subdivision using the declared method and one complete output set	output quantities; prices or physical driver; shared burden	attributed burden by intended output	iso-14044-allocation
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_field_emissions; species-specific activity ledger, method pathway and factor basis, matched accepted output	Identity-specific exchanges and reconciled activity records
