  2. 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 .

  3. Soil pH - Wikipedia

    en.wikipedia.org/wiki/Soil_pH

    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.

  4. Freshwater acidification - Wikipedia

    en.wikipedia.org/wiki/Freshwater_acidification

    Freshwater acidification is primarily caused by sulfur oxides (SO x) and nitrogen oxides (NO x) entering the water from atmospheric depositions and soil leaching. [1] Carbonic acid and dissolved carbon dioxide can also enter freshwaters, in a similar manner associated with runoff, through carbon dioxide-rich soils. [1]

  5. Acidification - Wikipedia

    en.wikipedia.org/wiki/Acidification

    Acidification may refer to: Ocean acidification, decrease in the pH of the Earth's oceans; Freshwater acidification, atmospheric depositions and soil leaching of SOx and NOx; Soil acidification, buildup of hydrogen cations, which reduces the soil pH; Souring, a cooking technique

  6. Alkali soil - Wikipedia

    en.wikipedia.org/wiki/Alkali_soil

    Water with excess H 3 O + ions is called acid (pH < 7), and water with excess OH – ions is called alkaline or rather basic (pH > 7). Soil moisture with pH < 4 is called very acid and with pH > 10 very alkaline (basic). H 2 CO 3 (carbonic acid) is unstable and produces H 2 O (water) and CO 2 (carbon dioxide gas, escaping into the atmosphere).

  8. Agricultural soil science - Wikipedia

    en.wikipedia.org/wiki/Agricultural_soil_science

    Soil acidity or soil pH and cation-exchange capacity: Root cells act as hydrogen pumps and the surrounding concentration of hydrogen ions affects their ability to absorb nutrients. pH is a measure of this concentration. Each plant species achieves maximum growth in a particular pH range, yet the vast majority of edible plants can grow in soil ...
