How to Calculate and Solve for Frequency of Irrigation | Methods of Application of Water

The image above represents frequency of irrigation. To calculate frequency of irrigation, two essential parameters are needed and these parameters are Minimum Depth of Water (d_w) and Depth of Water for Specified Period (c_u).

The formula for calculating frequency of irrigation:

f_w = ^d_w / _cu

Where:

f_w = Frequency of Irrigation
d_w = Minimum Depth of Water
c_u = Depth of Water for Specified Period

Let’s solve an example;
Find the frequency of irrigation when the minimum depth of water is 22 and the depth of water for specified period is 44.

This implies that;

d_w = Minimum Depth of Water = 22
c_u = Depth of Water for Specified Period = 44

That is, f_w = ^d_w / _cu
f_w = ²² / ₄₄
f_w = 0.5

Therefore, the frequency of irrigation is 0.5.

Calculating the Minimum Depth of Water when the Frequency of Irrigation and the Depth of Water for Specified Period are Given

d_w = f_w x c_u

Where;

d_w = Minimum Depth of Water
f_w = Frequency of Irrigation
c_u = Depth of Water for Specified Period

Let’s solve an example;
Find the minimum depth of water when the frequency of irrigation is 12 and the depth of water for specified period is 9.

This implies that;

f_w = Frequency of Irrigation = 12
c_u = Depth of Water for Specified Period = 9

So, d_w = f_w x c_u
d_w = 12 x 9
d_w = 108

Therefore, the minimum depth of water is 108.

Calculating the Depth of Water for Specified Period when the Frequency of Irrigation and the Minimum Depth of Water are Given

c_u = ^d_w / _fw

Where;

c_u = Depth of Water for Specified Period
f_w = Frequency of Irrigation
d_w = Minimum Depth of Water

Let’s solve an example;
Find the depth of water for specified period when the frequency of irrigation is 15 and the minimum depth of water is 75.

This implies that;

f_w = Frequency of Irrigation = 15
d_w = Minimum Depth of Water = 75

That is, c_u = ^d_w / _fw
c_u = ⁷⁵ / ₁₅
c_u = 5

Therefore, the depth of water for a specified period is 5.
