The average value of particle density of soil is:

Correct option is A

Correct Answer: (A) 2.65 g/cm³
Explanation:
→ The particle density of soil refers to the density of the solid particles in the soil, excluding the pore spaces.
→ On average, the particle density of most mineral soils is approximately 2.65 g/cm³.
→ This value is essential for calculating soil porosity, bulk density, and other physical properties related to soil health and water retention.
→ It serves as a standard reference for agronomic and engineering calculations in soil science.
Information Booster:
→ Average particle density: 2.65 g/cm³ for mineral soils.
→ Represents density of soil solids only, excluding pores.
→ Used to calculate soil porosity with bulk density.
→ Helps in determining soil compaction and water-holding capacity.
→ Crucial for agriculture, civil engineering, and environmental studies.
→ Particle density varies slightly for organic soils, usually lower than mineral soils.
→ Provides a reference standard for soil physical property calculations.
