Soil Compaction Calculator
Estimate soil bulk density to evaluate soil compaction risk.
Inputs
How It Works
Bulk Density (g/cm³) =
Dry Soil Weight ÷ Core Volume
Higher bulk density values may indicate soil compaction and restricted root growth.

FAQ
What is a critical bulk density?
For many soils, bulk density above 1.6 g/cm³ may restrict root growth. Clay soils may be restrictive at lower values.
How does compaction affect crops?
Compaction reduces pore space, limits water infiltration, and restricts root development.
How can compaction be reduced?
Minimizing traffic, avoiding field operations when wet, and using cover crops can help reduce compaction.
Understanding Soil Compaction
Soil compaction occurs when soil particles are pressed together, reducing pore space. This limits root penetration, water movement, and oxygen availability.
Bulk density is a common indicator of compaction. Higher bulk density means fewer pore spaces and greater resistance to root growth.
Monitoring bulk density helps producers identify compaction problems and adjust traffic, tillage, or soil health practices accordingly.
