Soil Compaction – Tasmania . Key points. In agricultural soils, compaction is caused by compression from machinery traffic or stock trampling. Poor root growth and swollen root tips can indicate a compacted layer, usually between 10 and 40 cm. Nearly 70 per cent of the compaction caused by wheel traffic occurs on the first pass.
