Podzolic soil, also termed as podzol, or called the lessive soil, is a soil that is usually formed in a broadleaf forest and is mostly characterised by the average leaching, which is also highly susceptible to compaction. The eluvium horizon is usually 4 cm to 8 cm thick, and is low in iron and aluminium oxides and humus. WebA direct source of slow-release nutrients, SOM leads to improved chelation of microelements, helps buffer soil pH, and increases soil cation and anion exchange capacity which improves plant nutrient availability and decreases leaching potential (Weil and Magdoff, 2004).
