environments, soil pH decreases over time in a process called soil acidification, due to leaching from high amounts of In dry climates, rainfall. however, soil weathering and leaching are less intense and pH can be neutral or alkaline. Soils with high clay and organic matter content are more able to resist a drop or rise in pH have a (greater buffering capacity) than sandy soils. Although clay content cannot be modified, organic matter content can be changed by management. Sandy soils commonly have low organic matter content, resulting in alow buffering capacity , high rates of water percolation and infiltration making them more vulnerable to acidification . Soil pH Management Soil pH is affected by land use and management. Vegetation type impacts soil pH. For example, areas of land foresttend to be more acidic than. areas of Conversion of land from grassland. forestland or grassland to cropland can result in. drastic pH changes after a few years.
What is Hidradenitis Suppurativa? Hidradenitis Suppurativa (HS), also known in the European areas as Acne Inversa (AI), is a chronic, non-contagious, painful and quality of life impacting skin disease that causes boils to form in the folds of the skin and has a profound impact on quality of life1. Many will experience a boil at some point in life.
Onset is most common in the late teens and early 20's. HS outbreaks are painful in tender areas and may persist for years with interspersed periods of inflammation, often culminating in sudden drainage of pus. This process often forms open wounds that will not heal and frequently leads to significant scarring.
