A crop require 240mm of water, the crop is grown in a clay loam soil with 120mm available water at the field capacity effective root zone depth is 1.35m.find Total available wate (TAW)in root zone?

Total available water (TAW) in the root zone can be calculated using the formula:

TAW = Available water at field capacity x Effective root zone depth

Given:
Available water at field capacity = 120mm
Effective root zone depth = 1.35m

Converting the root zone depth to millimeters:
1.35m = 1350mm

Now, calculate TAW:
TAW = 120mm x 1350mm
TAW = 162000 mm

Therefore, the total available water (TAW) in the root zone is 162000mm.

Step 1: Calculate Total Water Available (TAW)

TAW = Available water at field capacity x Effective root zone depth
TAW = 120 mm x 1.35 m
TAW = 162 mm

Therefore, the Total Available Water (TAW) in the root zone is 162 mm.
