Question 1
What is bulk density?
- Mass of dry soil per unit volume including pore spaces
- Mass of solid soil particles only
- The ratio of voids to solids
💡 Hint: Focus on what bulk density measures.
Question 2
Is particle density generally higher than bulk density?
- True
- False
💡 Hint: Consider the definitions of both densities.

Challenge Problems
Push your limits with challenges.
Question 1
A researcher is studying two types of soil: Soil A has a bulk density of 1.4 g/cm³ and a particle density of 2.7 g/cm³. Soil B has a bulk density of 1.2 g/cm³ and a particle density of 2.65 g/cm³. Calculate the void ratios for both soils and discuss which soil might be better for plant growth.
💡 Hint: Use the void ratio formula from earlier.
Question 2
Analyze how different levels of bulk density might affect water retention and root development in agricultural practices.
💡 Hint: Think about how these properties interact with crop health.
