Description
Return rows*length*2*buffer as excluded area and subtract it from field area.
Agroforestry geometry separates row widths, root-zone intervals, canopy projections and repeated-strip area bases. Optical shade, optical porosity and a clear machinery corridor are different quantities. Ideal dimensions and supplied overlaps can support bookkeeping without establishing light conditions, aerodynamic shelter or safe access.
Return rows*length*2*buffer as excluded area and subtract it from field area.
When to use this tool
Use Alley Crop Netarea Tree Buffer Factor when checking the stated ideal tree-row, shade, buffer or area convention.
How to use the tool and how it works
- Enter fieldArea, treeRows, rowLength, bufferEachSide. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read excludedArea, cropArea. Use the output convention below.
Require nonnegative whole tree rows and nonnegative field area, row length and buffer width. Return rows*length*2*buffer as excluded area and subtract it from field area.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| fieldArea | Field Area | Required. Finite number; minimum 0. |
| treeRows | Tree Rows | Required. Safe integer; minimum 0. |
| rowLength | Row Length | Required. Finite number; minimum 0. |
| bufferEachSide | Buffer Each Side | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| excludedArea | Excluded Area | Required. Finite number. |
| cropArea | Crop Area | Required. Finite number. |

}Limitations and assumptions
- Buffer overlaps are not merged; negative remaining crop area is retained rather than demonstrating a valid layout.
- 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 measured terrain and canopy geometry, appropriate light/flow models and qualified agricultural/engineering assessment for actual layouts and operations.
