The neutron scattering method is not useful in estimating the moisture in

A. Acidic soils

B. Alluvial soils

C. Lateritic soils

D. Organic soils

Answer: Option D

Solution(By Examveda Team)

The neutron scattering technique is used to measure water content in the soil. The principle involved in this method is when a source is lowered into the soil and fast neutrons are emitted, the soil causes the neutron to slow and scatter. The result is that the probe becomes surrounded by a cloud of slow neutrons. But this method is not useful in estimating the moisture in organic soils.
