Description
Return observedMass*totalArea/harvestedArea*moistureCorrection.
Extension-training comparisons depend on score ranges, credit weights, unit factors, plot support and cost bases. A normalized difference or area-scaled harvest describes supplied records rather than proving learning, causal adoption or an agronomic effect. Caller-chosen factors need separate justification.
Return observedMass*totalArea/harvestedArea*moistureCorrection.
When to use this tool
Use Farm Demo Partial Plot Harvest Factor when checking the stated training, credit, demonstration-plot, unit or cost convention.
How to use the tool and how it works
- Enter observedMass, harvestedArea, totalArea, moistureCorrection. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read plotEquivalent. Use the output convention below.
Require nonnegative observed mass, totalArea>=harvestedArea>0 and moistureCorrection>0. Return observedMass*totalArea/harvestedArea*moistureCorrection.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| observedMass | Observed Mass | Required. Finite number; minimum 0. |
| harvestedArea | Harvested Area | Required. Finite number; strictly above 0. |
| totalArea | Total Area | Required. Finite number. |
| moistureCorrection | Positive supplied mass multiplier; not a moisture fraction or automatically derived correction. | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| plotEquivalent | Plot Equivalent | Required. Finite number. |

}Limitations and assumptions
- Assumes harvested area represents the full plot; the moisture multiplier is supplied rather than derived from a moisture measurement.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified representative observations and appropriate complete educational, statistical or budget analysis for substantive training, agricultural or funding decisions.
