Examples
-
This acidic soil solution enhances the processes of eluviation and leaching causing the removal of soluble base cations and aluminum and iron compounds from the A horizon.
Soil 2008
-
This layer is composed primarily of mineral particles and has two characteristics: it is the layer in which humus and other organic materials are mixed with mineral particles, and it is a zone of translocation from which eluviation has removed finer particles and soluble substances, both of which may be deposited at a lower layer.
Soil 2008
-
Movements of large amounts of water through the soil cause eluviation and leaching to occur.
Soil 2008
-
Common characteristics of recognition include immature development of eluviation in the A horizon and illuviation in the B horizon, and evidence of the beginning of weathering processes on parent material sediments.
Soil 2008
-
The A horizon is commonly differentiated into a darker upper horizon or organic accumulation, and a lower horizon showing loss of material by eluviation.
Soil 2008
-
Good drainage enhances an number of pedogenic processes of illuviation and eluviation that are responsible for the development of soil horizons.
Soil 2008
-
Generally, these horizons result from the processes of chemical weathering, eluviation, illuviation, and organic decomposition.
Soil 2008
-
It reduces the eluviation of soluble nutrients from the soil profile.
Soil 2008
-
This soil, however, has a calcareous parent material which results in a high pH and strong eluviation of clay from the A horizon.
