Description of practice

Wheel load carrying capacity is a measure of soil strength. Wheel load is calculated for specific tyres and inflation pressures and, to avoid soil stress, should not exceed carrying capacity. It is a useful and easily interpreted parameter for portraying compaction risk and is therefore respecting it is an effective guide for preventing soil compaction.

AMP16 01

Modest wheel loads and inflation pressures

Modest wheel loads and tyre inflation pressures result in higher soil pore volume, lower penetration resistance and higher hydraulic conductivity than a higher wheel load.

AMP16 02

Wide tyres

Lower weight tractors with wide tyres distribute wheel load, resulting in less soil compaction.

Assess risk of soil compaction

Terranimo® is a computer model that predicts the risk of soil compaction by farm machinery for real operating conditions. It classifies this risk, helping the farm manager to decide on the use of agricultural machines  to avoid soil structure damage.

Tractors on tracks

Tracks distribute pressure over a larger soil surface helping to avoid compaction (under dry conditions).
