Compacted Soils

Soils pressed by traffic or equipment, losing pore space so water, air and roots cannot move freely.

Soil condition

Profile

Bulk density
Above ~1.6 g/cm³ in loams
Causes
Foot traffic, mowers, construction
Remedies
Core aeration, deep tine, topdressing

Water & soil targets

Moisture (VWC)
Readings swing between saturated and dry
Salinity tolerance
Salts accumulate near surface
Drought tolerance
Roots stay shallow

Irrigation runs off; water doesn't reach roots.

Problems to watch

  • Runoff
  • Shallow roots
  • Black layer

Stress signs

  • Puddles
  • Thin, worn turf
  • Hard surface

Where you'll find it

  • High-traffic sports fields
  • Event lawns
  • Construction-affected trees
