Soil pH Soil pH Soil pH is a measure of the acidity or basicity (alkalinity) of a soil. pH is defined as the negative logarithm (base 10) of the activity of hydronium ions ( or, more precisely, ) in a solution. In soils, it is measured in a slurry of soil mixed with water (or a salt solution, such as 0.01 M ), and normally falls between 3 and 10, with 7 being neutral. Acid soils have a pH below 7 and alkaline soils have a pH above 7. Ultra-acidic soils (pH < 3.5) and very strongly alkaline soils (pH > 9)
Ortek Therapeutics Ortek Therapeutics Ortek Therapeutics, Inc. is a private healthcare company based in Roslyn Heights, New York which specializes in researching and commercializing oral care products. It was founded in 1998. To date, Ortek's commercial success is based on the company's patented AlkaGen Technology (an arginine bicarbonate/calcium carbonate complex). The Company plans on incorporating this technology in their sugarless soft chews, BasicBites. Arginine is a common amino acid found in many foods and is also naturally found in saliva. On tooth surfaces, arginine is broken down by certain pH rising plaque bacteria to acid-neutralizing alkali. This results in a sustained neutral
