  • Soil compaction UMN Extension

    Soil compaction changes pore space size, distribution and soil strength. One way to quantify the change is by measuring the bulk density. As the pore space decreases within a soil, the bulk density increases. Soils with a higher percentage of clay and silt, which naturally have more pore space, have a lower bulk density than sandier soils.

    Inherent factors that affect bulk density such as soil texture cannot be changed. Bulk density is dependent on soil organic matter, soil texture, the density of soil mineral (sand, silt, and clay) and their packing arrangement. As a rule of thumb, most rocks have a density of 2.65 g/cm3 so ideally, a silt loamsoil has 50% pore space a bulk and density of1.33 g/cm3. Generally, loose,

    Some of the factors that affect the amount of heat dissipated from the soil down the profile include; moisture content 22 and bulk density (Abu-Hamdeh, 2013). Soil moisture content: Moisture influences soil heat dissipation down the profile. The flow of heat is higher in a wet soil than in a dry soil where the pores are filled with air.

  • Effects of Soil Compaction

    The most direct effect of soil compaction is an increase in the bulk density of soil. Bulk density is the mass of oven-dry soil in a standard volume of soil, often given as grams per cubic centimeter (g/cm3). Optimum bulk densities for soils depend on the soil texture (Table 1). Whenever the bulk density exceeds a certain level, root growth is restricted. A note of

  • Physical properties of soil - Wikipedia

    Soil structure affects aeration, water movement, conduction of heat, plant root growth and resistance to erosion. Water, in turn, has a strong effect on soil structure, directly via the dissolution and precipitation of minerals, the mechanical destruction of aggregates (slaking) and indirectly by promoting plant, animal and microbial growth.

  • Effect of soil compaction on root growth ... - Plant and Soil
