  2. Soil pH - Wikipedia

    en.wikipedia.org/wiki/Soil_pH

    With the addition of an equal volume of 0.02 M to the soil suspension that was prepared for the water pH, the final soil-solution ratio is 1:2 0.01 M . A 20-g soil sample is mixed with 20 mL of reverse osmosis (RO) water (1:1 w:v) with occasional stirring.

  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 .

  4. Orders of magnitude (length) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(length)

    The centimetre (SI symbol: cm) is a unit of length in the metric system equal to 10 −2 metres (⁠ 1 / 100 ⁠ m = 0.01 m). To help compare different orders of magnitude , this section lists lengths between 10 −2 m and 10 −1 m (1 cm and 1 dm).

    A pH of 9.5 has 10 −9.5 moles hydronium ions per litre of solution (and also 10 −2.5 moles per litre OH −). A pH of 3.5 has one million times more hydronium ions per litre than a solution with pH of 9.5 (9.5 − 3.5 = 6 or 10 6) and is more acidic. [115] The effect of pH on a soil is to remove from the soil or to make available certain ions.

  6. Physical properties of soil - Wikipedia

    en.wikipedia.org/wiki/Physical_properties_of_soil

    Clay cannot be resolved by optical microscopes as its particles are 0.002 mm (7.9 × 10 −5 in) or less in diameter and a thickness of only 10 angstroms (1010 m). [ 16 ] [ 17 ] In medium-textured soils, clay is often washed downward through the soil profile (a process called eluviation ) and accumulates in the subsoil (a process called ...

  7. Canadian system of soil classification - Wikipedia

    Eutric Brunisols have the same basic properties as Melanic Brunisols, except that the Ah horizon, if any, is less than 10 cm thick. Sombric Brunisols have an Ah horizon at least 10 cm thick, and are acid and their pH is below 5.5. Dystric Brunisols are acidic and do not have an Ah horizon 10 cm thick.

  8. pH - Wikipedia

    For instance, a 5 × 10 −8 M solution of HCl would be expected to have a pH of 7.3 based on the above procedure, which is incorrect as it is acidic and should have a pH of less than 7. In such cases, the system can be treated as a mixture of the acid or base and water, which is an amphoteric substance.

  9. Acid sulfate soil - Wikipedia

    en.wikipedia.org/wiki/Acid_sulfate_soil

    Sulfuric material refers to soil material that has a pH of less than 4 owing to the oxidation of sulfidic material. [ 27 ] Sulfidic material refers to “soil materials containing detectable inorganic sulfides (≥0.01% sulfidic sulfur) that can exist as horizons or layers at least 30 mm thick or as surficial features”, [ 27 ] and is further ...
