Throughout history the soil environment has been manipulated for increasing plant production by manuring and soil tillage, but with limited consideration of plant roots. During grazing soil is trodden to a greater or lesser extent and compaction of the soil surface will occur, depending on a number of factors, particulary soil moisture status at the time of grazing. Renewed interest in grass-white clover systems may result in compacted soils on intensively managed pastures because of high stocking rates and long grazing seasons. In future, persistency and productivity of white clover will be faced with more compacted soils. Compaction probably changes the soil environment in more ways that stress sward growth than any other single factor. It directly alters four physical properties: bulk density, soil strength, pore size distribution and aeration
