The science of soil compactionAgriculture 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.

Soil Tilth and Management Oxford Research Encyclopedia

Poor soil tilth is generally associated with compaction, induced by wheel traffic, animal trampling, and/or to natural soil consolidation (i.e., so-called hard-setting behavior). The soil-tilth concept dates back to the early days of arable farming and has been addressed in soil-science literature since the 1920s.

Impact of Soil Compaction on Bulk Density and Root Biomass

The impact of soil compaction on bulk density and root biomass of Quercus petraea L. was assessed after 85 years of reclamation of post-lignite mining soil at Welzow-South, in Lusatia, Germany. Bulk density of core soils sampled from 20 to 25 cm, 100 to 105 cm, and 200 to 205 cm depths and oven-dried biomass of Q. petraea roots sampled from 0 to 30‡cm and at successive depths of 20

How Soil Compaction Affects the Growth of PlantsHome

Soil compaction affects gardens large and small and can be made increasingly worse by foot traffic and improper tilling. Ideal soil is porous, allowing ample air flow between particles. When soils

Soil CompactionThe Center for Sustainable Agriculture

Soil health is critical for maximizing economic and environmental benefits in agriculture; preventing compaction is a key aspect of its management. Compacted soils hold less air and water, are less able to support diverse soil organisms, limit plant root depth and result in less infiltration and more runoff.

Soil compaction overviewAgriculture and Food

All surface and subsurface soils can be compacted; some more easily than others. Livestock and machinery easily compact surface soil, as well as natural forces mainly induced by wetting and drying. Subsoil compaction can occur in most Western Australian agricultural soils due to agricultural machinery or natural soil characteristics and conditions.
