Water Requirement of Crops MCQ with answer and solution

Easy level · Asked in State AE, State JE, GPSC AE

If the ratio of electrical conductivity of irrigation water to leached water is 0.25, then what would be the leaching requirement of that soil?

Solution

Concept

Leaching requirement

Formula

LR = EC_irrigation / EC_drainage

Step-by-step solution

1. LR = EC of irrigation water/EC of drainage (leached) water. 2. Given ratio = 0.25, so LR = 0.25.

Explanation

The ratio itself is the leaching requirement.

Why the other options are wrong

Others are not equal to the given ratio.

Shortcut

LR = ECw/ECdw.

Correct answer: B) 0.25
