Understand the topic

Start with the explanation.

Post-harvest control begins at picking. Product temperature, handling time, pack design and distribution conditions should be recorded as a chain rather than treated as a cold-room claim.

Part 01

Why this matters

The post-harvest chain links harvest lots to cooling, grading, packing, storage, transport and customer specification.

AI teaching illustrationHarvest and reset

Picking, grading, packing and room reset are connected tasks. A strong flush can still lose value through poor handling or delayed dispatch.

Conceptual explanation—not a real farm photograph, diagnostic finding or construction specification.
Part 02

What to look for

Build a record before making a change.

  • Product temperature
  • Time and handling events
  • Surface condition and damage
  • Package and transport environment
Part 03

How to make the next decision

Use the observation to narrow a decision, then verify the response.

  • Prioritise cooling by risk
  • Choose and validate pack format
  • Maintain lot identity
  • Reject unsupported shelf-life promises
Part 04

What to check before moving on

This topic cannot be interpreted in isolation.

  • Harvest hygiene
  • Cooling capacity
  • Clean packaging
  • Cold-chain continuity
  • Market specification
Part 05

On the farm

Start in the room with product temperature and time and handling events. Record location, stage and recent events before changing the process.

Part 06

The technical explanation

The technical model joins harvest hygiene, cooling capacity, clean packaging. Any operating value must be attached to a registered parameter, measurement location and applicable condition.

Part 07

What the evidence can tell you

This page is grounded in: Technical Bulletins; Mushroom Cultivation, Marketing and Consumption. Source provenance does not remove the need to check stage, system, date and local applicability.

01

Pick with the next task in mind

The harvested crop is a delicate food product. Picking affects subsequent grading and handling. Skill and clean working practices matter beyond the amount picked.

Try this on your farm

Train pickers on the crop-specific method and buyer grade. Keep harvest containers and tools clean.

02

Separate grades and rejects

The lot is divided before it is priced or packed. Buyer requirements determine accepted grades. The illustrated sizes are not a universal grading standard.

Try this on your farm

Weigh each accepted grade and the rejected or unsold quantity separately. Record the reason for rejection.

03

Know what the scale includes

The pack and the mushrooms both add weight. Net produce weight and total packed weight are different. Blank displays in this illustration are not measurement evidence.

Try this on your farm

Check the scale and record tare, net weight, pack count and batch identity under the actual buyer's specification.

04

Record acceptance and payment

Product handover and the financial record are connected. A delivery can be accepted before its money is received. Sales revenue is not the same as cash collected.

Try this on your farm

Record accepted quantity, agreed price, returns, payment received and outstanding balance. Reconcile these with harvest records.
