Definitions for "SOIL COMPACTION"
Reduction of the total pore space in a soil. Results in a soil that retains less water and resists root penetration. Soils with high clay content are more easily compacted than sandy soils.
The reduction of soil volume. For instance, the weight of heavy equipment on soils can compact the soil and thereby change it in some ways, such as in its ability to absorb water. Compacted soil is a major problem, taking thousands of acres permanently out of wildlife habitat. Trees will not grow in compacted soil.
Compression of the soil which results in reduced soil pore space (the spaces between soil particles), decreased movement of water and air into and within the soil, decreased soil water storage, and increased surface runoff and erosion.
Increase in the soil density that reduces soil drainage and soil aeration, often leading to decreased plant growth.
An increase in soil bulk density from an undisturbed state
A process that occurs as soil is squeezed repeatedly, decreasing the air spaces between soil particles and making the soil very hard.
Keywords:  subsidence, avoid, pressed, fill
Fill soils that have been pressed to avoid subsidence.
