What factors affect soil bulk density?
Density of soil mineral
Aggregates' packing arrangement
Soil organic matter
Soil texture
Presence and amount of rock fragment, soil depth, and soil texture affect the water capacity of soil
Loose, well-aggregated, porous, high organic matter soils have a lower bulk density
Sandy soils have a higher bulk density because of less pore space
Farmers can minimize soil disturbance by...
- Avoiding equipment operation on wet soil
- Using designated roads or rows for equipment transportation
Farmers can...
- Plant crops with a variety of rooting depths

Bulk Density
Farmers can increase soil organic matter by...
- Using no till
- Using cover crops
- Using solid manure or applying compost
- Using high residue crops
Farmers can decrease compaction by...
- Reducing the number of trips across the field with equipment
- Rotating livestock
Bulk density is a measurement of the weight of dry soil per unit volume
