Arrange the soil in the decreasing order of soil wetness:

(A) Friable / firm

(B) Very plastic

(C) Hard

(D) Inundated

Choose the correct answer from the options given below:

Correct option is C

Explanation of the Correct Option (c): (D), (B), (A), (C)
· Soil wetness refers to the amount of water present in the soil and is commonly described using field-consistency terms.
Correct decreasing order of soil wetness:
(D) Inundated
· Soil is completely saturated with free-standing water.
· Represents the maximum soil wetness condition.
(B) Very plastic
· Soil contains very high moisture content.
· Can be easily moulded and deformed.
· Indicates wet soil but without free water.
(A) Friable / firm
· Soil has moderate moisture.
· Crumbles easily when pressed.
· Ideal condition for tillage operations.
(C) Hard
· Soil is very dry.
· Strong resistance to deformation.
· Represents the lowest soil wetness.
· Hence, decreasing order of wetness is: Inundated → Very plastic → Friable/Firm → Hard
Explanation of Other Options
Option (a): (A), (B), (C), (D)
· Incorrect because:
· Inundated soil (wettest) is wrongly placed last.
Option (b): (B), (C), (D), (A)
· Incorrect because:
· Hard soil is drier than friable soil.
Option (d): (C), (B), (D), (A)
· Incorrect because:
· Hard soil cannot be the wettest condition.
Key Points:
· Inundated → saturated with free water
· Very plastic → very high moisture
· Friable/Firm → optimum moisture for cultivation
· Hard → very dry soil
