How to calculate soil porosity?
Understand the Problem
The question is asking for the method or formula used to calculate soil porosity, which is the measure of the void spaces in soil and affects water retention and soil health.
Answer
Soil Porosity = (1 - (Bulk Density ÷ Particle Density)) x 100
The final answer is obtained by using the formula: Soil Porosity = (1 - (Bulk Density ÷ Particle Density)) x 100

The final answer is obtained by using the formula: Soil Porosity = (1 - (Bulk Density ÷ Particle Density)) x 100
More Information
Soil porosity is typically expressed as a percentage and indicates the volume proportion of void spaces relative to the total soil volume. Higher porosity means better soil drainage and aeration.
Tips
A common mistake is incorrectly measuring the bulk density or particle density, which can lead to incorrect calculations. Ensure accurate measurements for reliable results.
