Vertisols of the world A more detailed map of the global distribution of Vertisols. A vertisol is a Soil Order in the USDA soil taxonomy [1] and a Reference Soil Group in the World Reference Base for Soil Resources (WRB). [2] It is also defined in many other soil classification systems. In the Australian Soil Classification it is called ...
Expansive clay, also called expansive soil, is a clay soil prone to large volume changes (swelling and shrinking) directly related to changes in water content. [1] Soils with a high content of expansive minerals can form deep cracks in drier seasons or years; such soils are called vertisols.
Calcaric Cambisol (Humic) profile in Des'a forest in Ethiopia. A Cambisol in the World Reference Base for Soil Resources (WRB) [1] is a soil in the beginning of soil formation. ...
Oxytocin is another chemical in the feel good cocktail that orgasm produces and one that affects women more so than men—namely because “when female brains develop in utero there are more ...
Due to the physical and chemical properties of some clays [4] (such as the Lias Group) large swelling occurs when water is absorbed. Conversely when the water dries up these clays contract (shrink). The presence of these clay minerals is what allows soils to have the capacity to shrink and swell.
Argillipedoturbation, sometimes referred to as self-mulching, is a process of soil mixing caused by the shrinking and swelling of the smectite clays contained in soil. [1] [2] It is an effect specific to soils of the vertisolic variety, and is triggered by the constant cycles of wetting and drying [1] It is characterized by wide (up to 2 centimetres (0.79 in)), deep (50 centimetres (20 in) or ...
According to the World Health Organization (WHO), it affects about 8% to 13% of women of reproductive age worldwide. PCOS is also the most common cause of infertility in women.
