Soil Moisture Deficit Calculator
The calculation of moisture deficit depends on target moisture and current moisture. This page shows the relationship and a worked starting case.
Enter values for moisture deficit
Target moisture and the other Soil Moisture Deficit fields share one scenario.
Purpose of the moisture deficit estimate
Soil Moisture Deficit focuses on Moisture deficit and combines Target moisture and Current moisture.
Use moisture deficit to compare current soil moisture with a target level, then inspect target moisture in the field.
How Soil Moisture Deficit performs the calculation
Soil Moisture Deficit finds the difference using Target moisture and Current moisture.
Using target moisture at 28% and current moisture at 19%, the example returns 9.00 percentage points and 47.4%.
Reading moisture deficit
Use Moisture deficit to compare current soil moisture with a target level. Keep the Soil Moisture Deficit inputs beside the output.
Deficit relative to current moisture supplements moisture deficit in Soil Moisture Deficit.
Target moisture and the other inputs
Moisture deficit is calculated from Target moisture and Current moisture. Check the Soil Moisture Deficit units before editing. Soil Carbon Stock Calculator addresses how to estimate organic carbon mass in a defined soil sample.
- Target moisture
- The Soil Moisture Deficit target is 28% in the starting case.
- Current moisture
- Soil Moisture Deficit currently demonstrates 19%; substitute the observation being evaluated.
Collecting data for Soil Moisture Deficit
Recheck the bed after settling, cultivation, or heavy traffic if those changes affect target moisture. Continue with Salt Leaching Requirement Calculator to compare irrigation-water salinity with a root-zone salinity limit.
Soil Moisture Deficit beyond the formula
Sensor readings should come from the same depth and calibration.
For Soil Moisture Deficit, verify the basis of Target moisture and Current moisture. Similar percentages can describe different totals. Keep gypsum product in a separate Gypsum Application Amount Calculator case.
Clarifying the Soil Moisture Deficit result
What scale does Target moisture use?
Soil Moisture Deficit reads Target moisture on a 0–100 percentage scale.
Should wet and dry soil values be mixed in Soil Moisture Deficit?
Only when the formula explicitly converts them. Keep moisture condition attached to moisture deficit.
How does “Sensor readings should come from the same depth and calibration.” affect moisture deficit?
The displayed result will not detect that condition. Check target moisture against the actual site before using it.
