Q150
The neutron scattering method is not useful in estimating the moisture in
A.
Acidic soils
B.
Alluvial soils
C.
Lateritic soils
D.
Organic soils
AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
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.
