  2. Acid sulfate soil - Wikipedia

    en.wikipedia.org/wiki/Acid_sulfate_soil

    The term ‘acid sulfate soils’ (ASS) was coined by the Working Party on Nomenclature and Methods for the first International Symposium on Acid Sulfate Soils (1972, Wageningen) to mean soils that contain, or have the potential to produce, sulfuric acid in quantities that cause significant and long-lasting changes in key soil properties. [22]

  3. Soil acidification - Wikipedia

    en.wikipedia.org/wiki/Soil_acidification

    Soil acidification is the buildup of hydrogen cations, which reduces the soil pH. Chemically, this happens when a proton donor gets added to the soil. The donor can be an acid, such as nitric acid, sulfuric acid, or carbonic acid. It can also be a compound such as aluminium sulfate, which reacts in the soil to

  5. Soil pH - Wikipedia

    en.wikipedia.org/wiki/Soil_pH

    Global variation in soil pH. Red = acidic soil. Yellow = neutral soil. Blue = alkaline soil. Black = no data. Soil pH is a measure of the acidity or basicity (alkalinity) of a soil. Soil pH is a key characteristic that can be used to make informative analysis both qualitative and quantitatively regarding soil characteristics.

  6. Phosphogypsum - Wikipedia

    en.wikipedia.org/wiki/Phosphogypsum

    Bioremediation may be used to clean up already contaminated water and soil. Microbials can remove heavy metals, radioactive material [citation needed], and any organic pollutants within, and reduce the sulfate material. [17] With suitable soil amendments and additives, PG can also support the growth of hardy plants, hopefully preventing further ...

  7. Soil chemistry - Wikipedia

    en.wikipedia.org/wiki/Soil_chemistry

    Soil chemistry is the study of the chemical characteristics of soil.Soil chemistry is affected by mineral composition, organic matter and environmental factors. In the early 1870s a consulting chemist to the Royal Agricultural Society in England, named J. Thomas Way, performed many experiments on how soils exchange ions, and is considered the father of soil chemistry. [1]

    This is a list of common chemical compounds with chemical formulae and CAS numbers, indexed by formula. This complements alternative listing at list of inorganic compounds. There is no complete list of chemical compounds since by nature the list would be infinite.

  9. Lignosulfonates - Wikipedia

    en.wikipedia.org/wiki/Lignosulfonates

    Lignosulfonates (LS) are water-soluble anionic polyelectrolyte polymers: they are byproducts from the production of wood pulp using sulfite pulping. [1] Most delignification in sulfite pulping involves acidic cleavage of ether bonds, which connect many of the constituents of lignin. [2]
