Seeds and Propagation
Seedling Survival Calculator
Seedling Survival uses its formula to measure transplant survival from planted and established counts. Its seedling survival output is tied to seedlings established and seedlings transplanted.
Enter values for seedling survival
Keep Seedling Survival units with their measurements.
Seedling survival: practical constraint
Define the establishment date before counting survivors.
A zero Seedlings transplanted leaves seedling survival undefined in Seedling Survival.
Before entering seedlings established
For seedling survival, collect Seedlings established and Seedlings transplanted on the Seedling Survival basis.
Seedlings established. Default in Seedling Survival: 168 seedlings.
Seedlings transplanted. Default in Seedling Survival: 190 seedlings.
Field notes for Seedling Survival
Note temperature, moisture, and treatment conditions beside seedling survival. They make a later propagation result easier to interpret.
Purpose of the seedling survival estimate
The planning question for Seedling Survival is whether you can measure transplant survival from planted and established counts. Seedling Survival measures this portion as Seedling survival.
Record adjustments outside Seedling survival separately.
Formula for seedling survival
Seedling Survival compares Seedlings established and Seedlings transplanted and reports the relationship as a percentage.
For the prefilled measurements—seedlings established at 168 seedlings and seedlings transplanted at 190 seedlings—the calculated answer is 88.42%. Need seeds per gram? Open Seeds per Gram Calculator.
What the seedling survival output means
Use Seedling survival to measure transplant survival from planted and established counts. Keep the Seedling Survival inputs beside the output.
Seedling loss supplements seedling survival in Seedling Survival. The Pot Up Container Count Calculator provides containers to prepare.
Seedlings established source record
Date the Seedling Survival case and retain Seedlings established and Seedlings transplanted.
Record how seedlings established was obtained and whether a conversion or estimate was involved.
Use the same seedling survival units for the observed outcome so the comparison remains meaningful.
What changes when seedlings established changes
Raise Seedlings established from 168 seedlings to 184.8 seedlings; keep seedlings transplanted fixed. Seedling survival moves from 88.42% to 97.26%.
Seedling Survival isolates seedlings established in this test; biological response remains outside the arithmetic.
If seedlings established has a plausible range, save low and high cases instead of averaging the endpoints.
Common questions about seedlings established
How does “Define the establishment date before counting survivors.” affect seedling survival?
No automatic adjustment is applied for it. Use a site-specific value for seedlings established when the condition is present.
Do propagation conditions affect Seedling Survival?
Temperature, moisture, treatment, and handling can change the stage measured by seedling survival.
Can Seedlings transplanted be zero in Seedling Survival?
In Seedling Survival, zero seedlings transplanted makes seedling survival undefined.
