Hydrophobic soil is a soil whose particles repel water. The layer of hydrophobicity is commonly found at or a few centimeters below the surface, parallel to the soil profile. [ 1 ] This layer can vary in thickness and abundance and is typically covered by a layer of ash or burned soil.
The hydrophobic soil particle is coated in a wax-like lipid compound with a hydrophilic head is attached to the individual particle and the hydrophobic tail is surrounding the outside of the particle. This hydrophobic tail shields any water from being absorbed by soil particles when many are affected.
Examples of hydrophobic molecules include the alkanes, oils, fats, and greasy substances in general. Hydrophobic materials are used for oil removal from water, the management of oil spills, and chemical separation processes to remove non-polar substances from polar compounds. [2] Hydrophobic is often used interchangeably with lipophilic, "fat ...
Soil compaction also impacts infiltration capacity. Compaction of soils results in decreased porosity within the soils, which decreases infiltration capacity. [4] Hydrophobic soils can develop after wildfires have happened, which can greatly diminish or completely prevent infiltration from occurring.
A gleysol or gley soil is a hydric soil that unless drained is saturated with groundwater for long enough to develop a characteristic gleyic colour pattern. The pattern is essentially made up of reddish, brownish, or yellowish colours at surfaces of soil particles and/or in the upper soil horizons mixed with greyish/blueish colours inside the ...
A Stagnosol in the World Reference Base for Soil Resources (WRB) is soil with strong mottling of the soil profile due to redox processes caused by stagnating surface water. Stagnosol (Ah-Bg1-Bgc-Bg2) showing pooled water. Stagnosols are periodically wet and mottled in the topsoil and subsoil, with or without concretions and/or bleaching.
Hydroponics is a type of horticulture and a subset of hydroculture which involves growing plants, usually crops or medicinal plants, without soil, by using water-based mineral nutrient solutions in an artificial environment.
A soil type is a taxonomic unit in soil science. All soils that share a certain set of well-defined properties form a distinctive soil type. [1] Soil type is a technical term of soil classification, the science that deals with the systematic categorization of soils. Every soil of the world belongs to a certain soil type. Soil type is an ...
