Purpose and description
Enable an agent to recognise an agricultural harvest operation, assess readiness and progress, and decide whether, when and how to gather a crop for its intended use.
Harvest is the operation or set of operations by which a cultivated crop is gathered from its growing site when it reaches a maturity or condition suitable for its intended use.
It can be Compare readiness evidence with the criteria for the crop's intended use.; Schedule or defer collection passes within a documented harvest window.; Match collection methods and resources to crop condition and field access.; Pause or redirect collection when conditions breach specified operating limits.; Reconcile collected quantities with remaining crop, field losses and collection damage.; Close a harvest pass and hand off traceable lots with unresolved exceptions recorded..
Distinguishing features
The activity gathers a crop or usable crop part from its growing site; transporting an already collected lot alone is not a harvest.
Removal is directed toward an intended use of the collected material; pruning or clearing solely to manage vegetation is outside scope.
Readiness is judged against the intended use and collection method; biological maturity alone does not define the harvest decision.
An instance has an operational boundary such as a field, crop cohort or collection pass; the yield quantity and the harvest season are related records, not the activity itself.
Harvest completion concerns the specified target and pass; it need not mean that the whole plant was removed or that no later harvest is possible.
Scope
+ Identification of the crop, growing area, harvestable part and intended use
+ Assessment of harvest readiness and the permissible collection window
+ Selection of harvest method, collection sequence and operational resources
+ Tracking of harvested quantities, field losses and damage during collection
+ Completion of harvest passes and transfer of identifiable crop lots
- Crop establishment and cultivation before harvest readiness
- The harvested material as a product with its own enduring properties
- Long-term storage, processing, distribution and sale
- Fishing, forestry and wild gathering pending confirmation of registry scope
- Metaphorical harvesting of data, energy or financial returns
Characteristics
- Harvest target
- Crop identity, growing site or cohort, and usable plant part Establishes what is being collected and prevents mixing distinct crop operations.
- Intended use
- Food, feed, seed, fibre, fuel, industrial input, or another specified use Determines which readiness and acceptance criteria the operation must satisfy.
- Harvest readiness
- Unassessed, not ready, ready, past target, or mixed; supported by explicit criteria Supports a collection decision without assuming a universal maturity threshold.
- Readiness observations
- Crop-specific indicators with declared units, sampling method, time and spatial coverage Makes the readiness judgement inspectable and exposes variation within the target.
- Collection window
- Earliest and latest acceptable collection times, with timezone and uncertainty Constrains scheduling and identifies the consequences of delay.
- Harvest method
- Manual, mechanised or mixed; selective or whole-target; removal and collection technique specified Connects crop condition to feasible equipment, labour and handling choices.
- Operational status
- Planned, underway, paused, completed or abandoned, recorded per pass Distinguishes an unfinished pass from a completed pass awaiting later regrowth or ripening.
- Collected quantity
- Mass, volume or count, with gross/net and moisture basis where applicable Supports progress tracking and comparisons on a consistent quantity basis.
- Field loss and collection damage
- Quantity or percentage with denominator, assessment method and attribution confidence Separates usable collection from material lost, missed or damaged during the operation.
- Harvest lot lineage
- Links from collection events and source areas to receiving lots and handoff records Preserves origin when multiple areas, passes or containers contribute to a lot.

Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 17 findings · 27 questions.
Crop target and pass Defines the material and operational unit that make this a particular harvest.
A field, a crop season and a selective picking pass can describe different boundaries and must not be treated as interchangeable.
Harvestable material
Identifies the crop part being gathered and the use that motivates collection.
Target and use
Record crop identity, usable part, source area and intended use as the basis for interpreting this operation.
- Which crop and plant part are being gathered, from which growing area or cohort? definition
- What intended use determines whether the gathered material is acceptable? boundary
Collection pass boundary
Separates the current collection event from other passes and neighbouring activities.
Pass identity
Specify whether this is selective collection, a whole-target harvest or one pass in a repeated sequence.
- What area, cohort, time interval and selection rule delimit this pass? boundary
- Does completion leave material intentionally available for later picking, regrowth or another use? action
Readiness and timing Connects crop observations to a justified decision about when to collect.
A harvest decision depends on the required product condition and how that condition varies across the growing area.
Readiness evidence
Captures the indicators and sampling behind a readiness judgement.
Crop-specific readiness
Record explicit readiness criteria and observations without prescribing thresholds across all crops.
- Which observed indicators and thresholds define readiness for this crop and intended use? definition
- When, where and how were those indicators sampled, and what variation did the samples reveal? measurement
Collection window
Describes timing limits and the evidence for acting now or waiting.
Timing tradeoffs
Document expected consequences of early or delayed collection and the conditions that would change the decision.
- What evidence supports the earliest and latest acceptable collection times? provenance
- Which change in crop condition or forecast would trigger starting, delaying or prioritising a pass? action
Field collection execution Describes how the target crop will be removed and gathered under actual field conditions.
Readiness does not establish whether a chosen method can collect the crop effectively within the available window.
Removal and gathering method
Connects the crop target to collection technique, selectivity and resource capacity.
Method fit
Record the removal technique and the labour, equipment and containers required for the planned pass.
- How will the usable part be detached or removed and gathered, and how will unready material be treated? action
- What effective collection rate can the available crew and equipment sustain under the observed conditions? measurement
Field operating limits
Identifies conditions that permit, constrain or interrupt collection.
Go and stop conditions
Record applicable limits for access, crop wetness, terrain and other conditions affecting the selected method.
- Which observed field and weather conditions are outside the operating limits of the selected collection method? measurement
- What conditions require pausing, changing equipment or moving collection to another part of the field? action
Recovery, loss and completion Accounts for what was collected, what remained and whether the pass achieved its target.
Collected tonnage alone cannot distinguish successful recovery from incomplete coverage, intentional retention or avoidable loss.
Quantity and coverage
Measures harvest output against a declared target and measurement basis.
Recovered output
Record collected amounts and treated area while preserving measurement bases and uncertainty.
- How much material was collected, using what unit, tare adjustment and moisture basis where relevant? measurement
- Which source areas or crop cohorts have been covered, and what evidence supports declaring this pass complete? boundary
Uncollected and damaged material
Separates intentional retention, pre-existing loss and effects attributable to collection.
Loss attribution
Account for missed, dropped, rejected and damaged material without assuming that every uncollected portion is a harvest failure.
- What quantities were intentionally left, missed, dropped or rejected, and how were those categories measured? measurement
- What evidence distinguishes damage caused during collection from damage present before the pass? provenance
Lot integrity and handoff Preserves the identity and condition of collected material until responsibility passes to the next operation.
A harvest model must identify its output and endpoint so later handlers can interpret origin, elapsed time and collection exceptions.
Source-to-lot lineage
Links field collection events to containers and output lots.
Lot origin
Record which areas and collection intervals contributed to each lot, including splits and mixing.
- Which field areas, crop cohorts and collection times contributed material to this lot? provenance
- Were materials from different passes or readiness classes mixed, and can their contributions still be identified? boundary
Immediate transfer
Defines the collection endpoint and requirements for delivery to the next responsible operation.
Handoff condition
Record destination, transfer time, receiving responsibility and any unmet immediate handling requirements.
- At what event does harvest responsibility end, and who receives each collected lot? boundary
- What crop-specific handling or elapsed-time requirements must be met before handoff, and what action follows an exception? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.

Neighbouring kinds and how to tell them apart
Recalled without web access and unsourced; every item is a lead to verify.
- harvested produce - The gathered material is the result of harvesting; this entry covers the activity.
- harvest season - The season is the period during which harvesting occurs, rather than the operation itself.
- reaping - Reaping specifically involves cutting a standing crop, especially cereal grain; harvesting also includes picking, digging and other collection methods.
- threshing - Threshing separates grain or seed from the harvested plant material and may be integrated with harvesting or performed separately.
- postharvest handling - Postharvest handling concerns subsequent operations such as cooling, drying, sorting and storage; the exact operational boundary varies by crop and production system.
- Which of these neighbouring kinds and how to tell them apart hold for the sense of harvest this model covers, and on what evidence? provenance
What the second pass must settle
- Does vr.tr.harvest denote agricultural harvesting specifically, or also forestry, fishing and wild gathering, given the missing registry definition?
- Does an existing Vercy world model already own this agricultural activity sense, requiring a registry link instead of a separate publication?
- Which crop-specific references should establish readiness indicators, sampling practices and acceptable collection windows?
- Where should the harvest boundary fall for operations that combine cutting, field drying, threshing, cleaning or packing?
- Which accounting conventions should distinguish harvest losses from intentional retention, pre-existing damage and later postharvest losses?
