Question

The particle density of soils with very high organic matter content may vary from:

A 1 to 1.3 Mgm-3 Correct Answer Incorrect Answer
B 2.60 to 2.75 Mgm-3 Correct Answer Incorrect Answer
C 0.9 to 1.3 Mgm-3 Correct Answer Incorrect Answer
D 1.3 to 1.8 Mgm-3 Correct Answer Incorrect Answer
E 2.25 to 2.5 Mgm-3 Correct Answer Incorrect Answer

Solution

Particle densities for most mineral soils vary between the narrow limits of 2.60 to 2.75 Mg m-3. The particle density of soils with very high organic matter content may vary from 0.9 to 1.3 Mgm-3.
