Soil Compaction: Where, How Bad, What to Do?
www.ars.usda.govCompaction Definitions • Soil compaction – Decrease in soil volume and porosity, or increase in soil bulk density, due to mechanical stress on soil, for example, from traffic of agricultural machinery. Compaction can also occur naturally. • Surface compaction – compaction that occurs in the surface “plow layer”
