Soil Porosity Calculator
Determine the porosity of your soil to optimize water retention and aeration for healthier plants.
Typical range: 1.1-1.6 g/cm³
Default mineral soil value: 2.65 g/cm³
Frequently Asked Questions
Soil porosity refers to the percentage of pore space in soil that can hold air and water. It’s a critical factor in determining how well water drains through soil and how much air is available to plant roots.
Proper soil porosity ensures adequate oxygen for root respiration, sufficient water retention for plant needs, and good drainage to prevent waterlogging. Different plants thrive in soils with different porosity levels.
You can improve porosity by adding organic matter (compost), using cover crops, avoiding soil compaction, and incorporating coarse sand or perlite for heavy clay soils.
