تعريف hardpan في الإنجليزية الإنجليزية القاموس.
- a distinct layer of soil that is largely impervious to water
- A hard, relatively impervious, layer of SOIL lying just below the surface Sometimes synonymous for TILL
- A soil layer with physical characteristics that limit root penetration and restrict water movement
- Firm dirt surface off the fairway
- A hardened or cemented soil horizon, or layer The soil material is sandy, loamy, or clayey and is cemented by iron oxide, silica, calcium carbonate, or other substance
- a subsurface indurated horizon Red-brown hardpans in Australia are characterised by the presence of a porous matrix, commonly red-brown in colour, cemented by silica (usually hyalite), in a variety of transported or residual host materials
- Impervious layer found within the soil It can result from the precipitation of iron, illuviation of clay or the cementing of sand and gravel by calcium carbonate precipitates
- Cemented or compacted and often clayey layer in soil that cannot be penetrated by roots. Lime, gypsum, iron, and other minerals may be carried up to the surface of soil by capillary action and deposited to form a natural concrete. In agricultural situations, special equipment may be used to chisel away hardpan so that crop plants can grow
- A packed, non-porous soil layer that is difficult for water or a shovel to penetrate
- very firm, unyielding ground (many times bare) Example: You can find a lot of hardpan on hot dry plains courses
- Describes a soil condition of extreme compaction; compaction in layers
- A general term used to describe a hard, cemented soil layer which does not soften when wet and may be impervious to water
- The hard substratum
- crust or layer of hard subsoil encrusted with calcium-carbonate occurring in arid or semiarid regions
- A layer of impermeable material (usually clay) that water cannot soak through
- very firm, unyielding ground Especially if there is little grass Example: "You can find a lot of hardpan on hot dry plains courses which often results in tons of roll"
- A hard impervious layer composed chiefly of clay or organic materials cemented by relatively insoluble materials, which does not become plastic when wet, and definitely limits the downward movement of water and roots
- {i} layer of clay or other solid matter; unbroken soil; solid base, strong foundation
- A hardened soil layer in the lower A or in the B horizon caused by cementation of soil particles with organic matter or with materials such as silica or calcium carbonate The hardness does not change appreciably with changes in moisture content, and pieces of the hard layer do not disintegrate in water
- Same as Hard pan, under Hard, a
- A layer of earth so compacted that roots cannot penetrate it Back to alphabetical list
