  2. Soil pH - Wikipedia

    en.wikipedia.org/wiki/Soil_pH

    The prevailing view in the 1940s and 1950s was that P availability was maximized near neutrality (soil pH 6.5–7.5), and decreased at higher and lower pH. [ 29 ] [ 30 ] Interactions of phosphorus with pH in the moderately to slightly acidic range (pH 5.56.5) are, however, far more complex than is suggested by this view.

  3. Soil acidification - Wikipedia

    en.wikipedia.org/wiki/Soil_acidification

    In plants, soil acidification results in smaller, less durable roots. [27] Acidic soils sometimes damage the root tips reducing further growth. [28] Plant height is impaired and seed germination also decreases. Soil acidification impacts plant health, resulting in reduced cover and lower plant density. Overall, stunted growth is seen in plants ...

  4. 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 ...

  5. Soil - Wikipedia

    en.wikipedia.org/wiki/Soil

    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. Soils with high acidity tend to have toxic amounts of aluminium and manganese. [116]

  6. Plant nutrients in soil - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrients_in_soil

    Lack of phosphorus may interfere with the normal opening of the plant leaf stomata, decreased stomatal conductance resulting in decreased photosynthesis and respiration rates [85] while decreased transpiration increases plant temperature. [86] Phosphorus is most available when soil pH is 6.5 in mineral soils and 5.5 in organic soils. [74]

  7. Proctor compaction test - Wikipedia

    en.wikipedia.org/wiki/Proctor_compaction_test

    The energy exerted by compaction forces the soil to fill available voids, and the additional frictional forces between the soil particles improves the mechanical properties of the soil. Because a wide range of particles are needed in order to fill all available voids, well-graded soils tend to compact better than poorly graded soils.

  8. Topsoil - Wikipedia

    en.wikipedia.org/wiki/Topsoil

    Topsoil is composed of mineral particles and organic matter and usually extends to a depth of 5-10 inches (13–25 cm). Together these make a substrate capable of holding water and air which encourages biological activity.

  9. Composting toilet - Wikipedia

    en.wikipedia.org/wiki/Composting_toilet

    The material from composting toilets is a humus-like material, which can be suitable as a soil amendment for agriculture. Compost from residential composting toilets can be used in domestic gardens, and this is the main such use. Enriching soil with compost adds substantial nitrogen, phosphorus, potassium, carbon and calcium.
