Enter the field capacity and the wilting point into the Calculator. The calculator will evaluate the Plant Available Water.

## Plant Available Water Formula

PAW = FC - WP

Variables:

- PAW is the Plant Available Water ()
- FC is the field capacity
- WP is the wilting point

To calculate plant available water, subtract the wilting point from the field capacity.

## How to Calculate Plant Available Water?

The following steps outline how to calculate the Plant’s Available Water.

- First, determine the field capacity.
- Next, determine the wilting point.
- Next, gather the formula from above = PAW = FC – WP.
- Finally, calculate the Plant’s Available Water.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

field capacity = 95

wilting point = 60
