Harvest and Planning

Harvest Loss Calculator

For a defined garden case, Harvest Loss uses crop lost and total crop produced to find harvest loss.

Enter values for harvest loss

Read each Harvest Loss field note before calculating harvest loss.

lb

Use the value that represents crop lost.

lb

Use the value that represents total crop produced.

Harvest Loss in practical terms

The planning question for Harvest Loss is whether you can express unharvested or damaged crop as a percentage of production. Harvest Loss measures this portion as Harvest loss.

Record adjustments outside Harvest loss separately.

Harvest loss: practical constraint

Define whether field culls and storage losses are included.

A zero Total crop produced leaves harvest loss undefined in Harvest Loss. Use the Stored Crop Remaining tool when crop remaining needs its own calculation.

Formula for harvest loss

harvest loss = crop lost ÷ total crop produced × 100

Harvest Loss compares Crop lost and Total crop produced and reports the relationship as a percentage.

The starting case sets crop lost at 28 lb and total crop produced at 320 lb. Its harvest loss is 8.75%.

Measurements for Harvest Loss

Prepare Crop lost and Total crop produced for Harvest Loss. Keep unrelated records separate.

Crop lost
Default in Harvest Loss: 28 lb.
Total crop produced
Default in Harvest Loss: 320 lb.

Harvest loss: interpretation

Read Harvest loss as the answer to “Express unharvested or damaged crop as a percentage of production.” Keep the Harvest Loss units attached.

Usable harvest share supplements harvest loss in Harvest Loss.

After calculating harvest loss

The Harvest Loss record should identify the scenario, Crop lost and Total crop produced, and Harvest loss.

For crop lost, note whether the entry came from a measurement, count, report, or planning assumption.

Compare the eventual field outcome with harvest loss on the same unit basis, keeping both values.

A second Harvest Loss scenario

Raise Crop lost from 28 lb to 30.8 lb; keep total crop produced fixed. Harvest loss moves from 8.75% to 9.63%.

Harvest Loss isolates crop lost in this test; biological response remains outside the arithmetic.

If crop lost has a plausible range, save low and high cases instead of averaging the endpoints.

Clarifying the Harvest Loss result

Should gross and marketable yield be combined in Harvest Loss?

No. Choose one yield definition for harvest loss. Track culls, edible yield, packed weight, and storage loss separately when they matter.

How does “Define whether field culls and storage losses are included.” affect harvest loss?

Run a separate case if it changes crop lost; combining unlike conditions can hide the practical difference.

Can Total crop produced be zero in Harvest Loss?

In Harvest Loss, zero total crop produced makes harvest loss undefined.
