The image above represents water application efficiency. To calculate water application efficiency, two essential parameters are needed and these parameters are Water stored in the Root Zone of the Plant (ws) and Water delivered to the Irrigated Plot (wf).
The formula for calculating water application efficiency:
Ea = ws / wf
Where:
Ea = Water Application Efficiency
ws = Water stored in the Root Zone of the Plant
wf = Water delivered to the Irrigated Plot
Let’s solve an example;
Find the water application efficiency when the water stored in the root zone of the plant is 45 and the water delivered to the irrigated plot is 9.
This implies that;
ws = Water stored in the Root Zone of the Plant = 45
wf = Water delivered to the Irrigated Plot = 9
That is, Ea = ws / wf
Ea = 45 / 9
Ea = 5
Therefore, the water application efficiency is 5.
Calculating the Water Stored in the Root Zone of the Plant when the Water Application Efficiency and the Water Delivered to the Irrigated Plot are Given
ws = Ea x wf
Where;
ws = Water stored in the Root Zone of the Plant
Ea = Water Application Efficiency
wf = Water delivered to the Irrigated Plot
Let’s solve an example;
Find the water stored in the root zone of the plant when the water application efficiency is 15 and the water delivered to the irrigated plot is 4.

This implies that;
Ea = Water Application Efficiency = 15
wf = Water delivered to the Irrigated Plot = 4
ws = Ea x wf
So, ws = 15 x 4
ws = 60
Therefore, the water stored in the root zone of the plant is 60.

Calculating the Water Delivered to the Irrigated Plot when the Water Application Efficiency and the Water Stored in the Root Zone of the Plant are Given
wf = ws / Ea
Where;
wf = Water delivered to the Irrigated Plot
Ea = Water Application Efficiency
ws = Water stored in the Root Zone of the Plant
Let’s solve an example;
Find the water delivered to the irrigated plot when the water convergence efficiency is 12 and the water stored in the root zone of the plant is 48.
This implies that;
Ea = Water Application Efficiency = 12
ws = Water stored in the Root Zone of the Plant = 48
Then, wf = ws / Ea
wf = 48 / 12
wf = 4
Therefore, the water delivered to the irrigated plot is 4.
