Soil Water Storage Calculator
Soil Water Storage Calculator
Estimate root zone available water and refill volume from soil measurements.
The root zone can store available water only within the soil's measured capacity.
Enter suitable field capacity, wilting point and rooting depth values. Compare available storage with the chosen refill basis.
How to use Soil Water Storage Calculator
- Enter field capacity by volume, wilting point by volume and root depth.
- Enter allowed depletion share, growing area and application efficiency.
- Select Calculate result. Read the returned values alongside the assumptions below before copying, exporting or acting on the result.
Why choose this tool?
The soil measurement basis helps separate water storage from a guessed watering interval.
Before you use the result
Field capacity and wilting point must come from suitable soil measurements. This is not a pH or soil amendment calculator.
Questions about Soil Water Storage Calculator
Does this calculate soil pH or amendments?
No. It uses water storage measurements, not acidity or fertilizer recommendations.
What should I check before using Soil Water Storage Calculator?
Check Field capacity by volume, Wilting point by volume, Root depth and Allowed depletion share. Use the exact units shown beside the controls and replace any example values with your own inputs.
