  2. Soil pH - Wikipedia

    en.wikipedia.org/wiki/Soil_pH

    The soil pH usually increases when the total alkalinity increases, but the balance of the added cations also has a marked effect on the soil pH. For example, increasing the amount of sodium in an alkaline soil tends to induce dissolution of calcium carbonate , which increases the pH.

  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 ...

    English: Effect of pH on the root availability of the essential elements in soil. Blue denotes the ideal soil pH for the majority of plants (slightly acidic). Inspired by an illustration from the North Carolina Extension Gardener Handbook

    Soil pH influences your plant’s ability to uptake nutrients from the soil. If the soil pH is too high, plants are not able to absorb many micronutrients, such as manganese and iron. When soil pH ...

  6. Soil biodiversity - Wikipedia

    en.wikipedia.org/wiki/Soil_biodiversity

    The number of seeds that are even able to germinate in acidic soil is much lower than the number of seeds that can sprout in a more neutral pH soil. [7] These limitations to the growth of plants can have a very negative effect on plant health, leading to a decrease in the overall plant population. These effects occur regardless of the biome.

  7. Plant nutrients in soil - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrients_in_soil

    Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...

  8. Base-cation saturation ratio - Wikipedia

    en.wikipedia.org/wiki/Base-cation_saturation_ratio

    Hence, any changes in mineral balance in the soil are unlikely to affect soil organism populations beyond the effects expected by altering pH. Studies have backed this up—Schonbeck [ 30 ] showed that a reduction of Mg saturation had no detectable effect on soil organic matter , biological activity, weed growth, or incidence of disease.
