Question

Given below are two statements:
Statement (I): The soil moisture depletion method is usually employed to determine the consumptive use of unirrigated field crops grown on fairly uniform soils when the depth to the ground water is such that it will not influence the soil moisture fluctuation within the root zone.
Statement (II): The field experimental plots technique though satisfactory for computing seasonal water requirements, does not provide information on intermediate soil moisture condition, short term use, profile use, deep percolation losses and peak use rate of the crop.
In light of the above statements, choose the most appropriate answer from the options given below:

• A. Both Statement (I) and Statement (II) are correct.
• B. Both Statement (I) and Statement (II) are incorrect.
• C. Statement (I) is correct but Statement (II) is incorrect.
• D. Statement (I) is incorrect but Statement (II) is correct.

Hint:

To measure short-term, precise daily consumptive use, researchers use high-precision weighing lysimeters rather than soil moisture depletion or open field plots.

Answer 1

The Correct Option is A
