Rows are grouped into Candidate, Watch, Early, Late, and Insufficient so the next action is obvious.
Orchard Harvest Readiness Memo
Enter Brix, firmness, skin color stage, days after bloom, and GDD, then sort the rows into candidate harvest notes.
Use it as a shared judgment memo across crops, blocks, and regions. It helps you compare signals; it does not predict a harvest date.

What this tool shows
A weighted score combines Brix, firmness, skin color, days after bloom, and GDD.
Use preset profiles, or switch to Custom when your crop needs its own threshold band.
Notes
- This is judgment support, not a harvest forecast.
- Treat the score as a memo for comparing blocks, cultivars, and dates, not as a fixed answer.
- If observations are incomplete, confidence drops and the row may stay in Insufficient.
- After rain, heat, or rapid fruit change, update the row and review the ranking again.
How to use
- 1. Choose a crop-family preset, or keep Custom if you want to define your own bands.
- 2. Enter the observed values for Brix, firmness, skin color stage, days after bloom, and GDD.
- 3. Adjust the candidate and watch thresholds, plus metric weights, if you want a stricter or looser profile.
- 4. Review the top candidate, the grouped rows, and the memo table to see why each row moved.
- 5. Save a profile or copy the share URL so the same comparison can be reused later.
Sample cases
Pome block close to harvest
Input
General orchard preset, Brix 14.8, firmness 68 N, skin color stage 4, 132 days after bloom, 1360 GDD
Output
Candidate. Score 86 with high confidence. Brix and color are inside the band, and firmness is near the upper edge.
Citrus block still maturing
Input
Citrus preset, Brix 11.2, firmness 32 N, skin color stage 2, 165 days after bloom, 1980 GDD
Output
Watch. Score 61 with medium confidence. Timing signals are close, but sugar is still behind the band.
Glossary
Brix
A refractometer reading that is often used as a rough sugar proxy.
Firmness
How strongly the fruit resists pressure. It is a useful texture and maturity clue.
Skin color stage
A local ripening scale for peel or skin color, usually based on stage numbers.
GDD
Growing degree days, or accumulated heat units, measured with the same base method across blocks.
Logic
Each metric is scored against the selected band and soft margin.
The row score is the weighted average of the present metric scores.
Rows at or above the candidate threshold become Candidate; rows at or above the watch threshold become Watch.
Below the watch threshold, direction decides whether the row is Early or Late.
Confidence is High when at least four metrics are present and the score is close to the candidate threshold.
Frequently asked questions
Is this a harvest prediction model?
No. It is a decision-support memo that helps you compare observations and organize a block-by-block judgment.
Can I use it across different crops?
Yes. Start with a preset profile, then switch to Custom if the crop needs a different band or weight set.
What if I only know some of the metrics?
You can still use the tool, but confidence will fall. Missing values make the result less complete and may keep the row in Insufficient.
Does it support both metric and imperial firmness units?
Yes. You can use N, kgf, or lbf, and set the default unit for new rows.
Can I save and share the same profile?
Yes. Profiles can be saved locally and the same context can be shared with a URL.
