Match List-I with List-II:

List I (Soil parameters)	List II (Measurement)
(A) Bulk Density	(I) Cl³⁶
(B) Soil water content	(II) C¹³
(C) Seepage	(III) H²
(D) Soil Salinity	(IV) Am-Be
(E) Soil aggregation	(V) Cs¹³⁷

Choose the correct answer from the options given below:

Correct option is A

• Bulk Density is commonly measured using Cs¹³⁷ (V) due to its effectiveness in evaluating soil compaction and porosity.
• Soil water content is assessed using Am-Be (IV) neutron probes.
• Seepage measurement involves H² (III), especially in water movement studies.
• Soil Salinity is traced using Cl³⁶ (I) isotopes to track salt movement.
• Soil aggregation can be studied using C¹³ (II) labeled carbon in organic matter decomposition.
Hence, the correct match is:
(A)-(V), (B)-(IV), (C)-(III), (D)-(I), (E)-(II) → Option (a)
