Description
Sum cations and return 100*sum/exchangeCapacity.
Agrochemical comparisons depend on reference-equivalent, charge, temperature and method conventions. A neutralizing-value product, charge-basis saturation or two-point interpolation is a limited calculation; it does not establish a soil treatment need, actual material performance or valid analytical certificate.
Sum cations and return 100*sum/exchangeCapacity.
When to use this tool
Use Soil Exchange Complex Base Saturation Term when checking the stated supplied chemical property, interpolation or metadata convention.
How to use the tool and how it works
- Enter baseCations, exchangeCapacity. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read baseTotal, saturationPercent. Use the output convention below.
Require positive exchange capacity and nonnegative base-cation amounts. Sum cations and return 100*sum/exchangeCapacity.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| baseCations | Nonnegative exchangeable base-cation charge amounts on the same basis as exchangeCapacity. | Required. Array of finite number; maximum items 256. |
| exchangeCapacity | Exchange Capacity | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| baseTotal | Base Total | Required. Finite number. |
| saturationPercent | 100*baseTotal/exchangeCapacity; may exceed 100. Unit: %. | Required. Finite number. |

}Limitations and assumptions
- Cation amounts and capacity must use the same charge basis; saturation can exceed 100% and no analytical consistency or soil-management decision is established.
- 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 methods and material properties with a complete suitable chemical/agronomic assessment for actual interpretation or handling decisions.
