Podzol means "under-ash" and is derived from the Russian под (pod) + зола́ (zola); the full form is подзо́листая по́чва (podzolistaya pochva), meaning "under-ashed soil". The term was first given in mid-1875 by Vasily Dokuchaev.
Podzol soil monolith with inconspicuous eluviation; coarse granular structure of top mineral horizon (Ahe or Ap) is evidence of earthworm invasion. These acid soils have a B horizon containing accumulations of amorphous materials composed of humified organic matter associated with aluminum and iron. They develop most commonly in sandy materials ...
Podsolisation is an extreme form of leaching which causes the eluviation of iron and aluminium sesquioxides. [1]The process generally occurs in areas where precipitation is greater than evapotranspiration.
In the World Reference Base for Soil Resources, [1] these soils are called Umbrisols, and the Soil Atlas of Europe [2] shows a preponderance of this kind of soil in north-west Spain. There is a tendency for the soils to occur in oceanic areas, where there is abundant rainfall throughout the year, winters are mild and summers relatively cool.
Podzol soils (Polish: Gleby bielicoziemne; WRB: Podzols; ST: Spodosols) That order groups all soils where main soil developing process was podzolisation , spodic horizon is diagnostic for that group.
Plaggen soil or plaggic anthrosol [1] is a type of soil created in parts of northwest Europe [2] in the Middle Ages, as a result of so-called "plaggen" agriculture on marginal podzol soils. In order to fertilize the fields, pieces of heath or grass including roots and humus ("plaggen") were cut and used as bedding for cattle or sheep.
Berkshire soil series is the name given to a well-drained loam or sandy loam soil which has developed on glacial till in parts of southern Quebec, eastern New York State and New England south to Massachusetts.
The pH is measured in soil-water (1:1) and soil-salt (1:2 ) solutions. For convenience, the pH is initially measured in water and then measured in CaCl 2 {\displaystyle {\ce {CaCl2}}} . With the addition of an equal volume of 0.02 M CaCl 2 {\displaystyle {\ce {CaCl2}}} to the soil suspension that was prepared for the water pH, the final soil ...
