Question

Match List-I with List-II

List-I (Theory proposed) & List-II (Author)
(A) Father of fertilizer Chemistry & (I) Jackson
(B) Nutrient index & (II) Stanley A Barber
(C) Root interception & (III) Liebig
(D) Weathering index & (IV) Parker

• (A) - (II), (B) - (III), (C) - (IV), (D) - (I)
• (A) - (I), (B) - (II), (C) - (III), (D) - (IV)
• (A) - (I), (B) - (II), (C) - (IV), (D) - (III)
• (A) - (III), (B) - (IV), (C) - (II), (D) - (I)

Hint:

Remember the core contributions: Liebig is the Father of Agricultural/Fertilizer Chemistry, and Barber is famous for the Root Interception theory of nutrient uptake. Matching these two immediately points to the correct option.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
To solve this matching question, we must identify the prominent scientists, chemists, and soil scientists associated with foundational agricultural chemistry and soil mineralogy concepts.

Step 3: Detailed Explanation:
Let us match each concept in List-I with its correct author/proposer in List-II:
- (A) Father of fertilizer Chemistry $\rightarrow$ Liebig (III): Justus von Liebig is considered the "Father of the Fertilizer Industry" and agricultural chemistry.
He formulated the "Law of the Minimum" and popularized the use of mineral fertilizers over organic manures in the 19th century.
- (B) Nutrient index $\rightarrow$ Parker (IV): F.W. Parker proposed the concept of the "Nutrient Index" in 1951 as a standardized method to evaluate and compare the overall fertility status of different soils.
- (C) Root interception $\rightarrow$ Stanley A Barber (II): Stanley A. Barber proposed and quantified the three primary pathways by which plant roots absorb nutrients from the soil: root interception, mass flow, and diffusion.
- (D) Weathering index $\rightarrow$ Jackson (I): M.L. Jackson proposed the 13 weathering stages of clay-sized minerals in soils, which serves as a standard "weathering index" in soil mineralogy.
This matching sequence gives: (A) - (III), (B) - (IV), (C) - (II), (D) - (I).
This matches Option (D).

Step 4: Final Answer:
The correct matching sequence is (A) - (III), (B) - (IV), (C) - (II), (D) - (I).
