  • The science of soil compaction | Agriculture and Food

    Soil compaction is rearrangement of soil particles and reduction in macro-porosity and total pore space by stresses. Stresses can be external such as those from machinery or internal from increasing pore water suction during drainage and drying. The main cause of subsoil compaction on agricultural soils is cropping machinery, especially heavy air carts, harvesters and chaser bins.
