1. What is Soil Density?

Definition: Soil density (ρ) is the mass of soil per unit volume, typically expressed in kg/m³.

Purpose: Understanding soil density is crucial for construction, agriculture, and environmental engineering projects.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density of soil (kg/m³)
• \( m \) — Mass of soil (kg)
• \( V \) — Volume of soil (m³)

Explanation: The mass of soil is divided by its volume to calculate its density.

3. Importance of Soil Density

Details: Soil density affects load-bearing capacity, water retention, and root penetration in agricultural applications.

4. Using the Calculator

Tips: Enter the mass of soil in kilograms and volume in cubic meters. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical soil density range?
A: Most soils range from 1,000 to 2,000 kg/m³, with clay soils typically denser than sandy soils.

Q2: How do I measure soil mass?
A: Use a scale to weigh a known volume of soil after drying to remove moisture.

Q3: How do I measure soil volume?
A: For loose soil, use a container of known volume. For in-situ measurements, use displacement methods.

Q4: What's bulk density vs particle density?
A: Bulk density includes pore spaces, while particle density measures only the solid particles.

Q5: Why does soil density matter in construction?
A: It determines bearing capacity and settlement characteristics for foundations.
