  2. Soil acidification - Wikipedia

    en.wikipedia.org/wiki/Soil_acidification

    Likewise, acid rain that falls on soil and on plant leaves causes drying of the waxy leaf cuticle; which ultimately causes rapid water loss from the plant to the outside atmosphere and results in death of the plant. To see if a plant is being affected by soil acidification, one can closely observe the plant leaves.

  3. Acid rain - Wikipedia

    en.wikipedia.org/wiki/Acid_rain

    Acid rain is also capable of detrimenting soil composition by stripping it of nutrients such as calcium and magnesium which play a role in plant growth and maintaining healthy soil. In terms of human infrastructure, acid rain also causes paint to peel, corrosion of steel structures such as bridges, and weathering of stone buildings and statues ...

  4. Freshwater acidification - Wikipedia

    en.wikipedia.org/wiki/Freshwater_acidification

    Diagram depicting the sources and cycles of acid rain precipitation. Freshwater acidification occurs when acidic inputs enter a body of fresh water through the weathering of rocks, invasion of acidifying gas (e.g. carbon dioxide), or by the reduction of acid anions, like sulfate and nitrate within a lake, pond, or reservoir. [1]

  6. Soil pH - Wikipedia

    en.wikipedia.org/wiki/Soil_pH

    The pH is measured in soil-water (1:1) and soil-salt (1:2 ) solutions. For convenience, the pH is initially measured in water and then measured in CaCl 2 {\displaystyle {\ce {CaCl2}}} . With the addition of an equal volume of 0.02 M CaCl 2 {\displaystyle {\ce {CaCl2}}} to the soil suspension that was prepared for the water pH, the final soil ...

  7. Leaching (agriculture) - Wikipedia

    en.wikipedia.org/wiki/Leaching_(agriculture)

    soil type and structure. For example, sandy soil holds little water while clay soils have high water-retention rates; the amount of water used by the plants/crops; how much nitrate is already present in the soil. [3] The level of nitrous oxide (N 2 O) in the Earth's atmosphere is increasing at a rate of 0.2 to 0.3% annually.

  8. Pollution in Canada - Wikipedia

    en.wikipedia.org/wiki/Pollution_in_Canada

    Acid rain is rain that has been contaminated by airborne chemicals, making it acidic. [6] Two major causes of acid rain are sulphur dioxide and nitrogen oxide. [7] Acid rain can cause damage to soil, water, wildlife, plants and buildings. Additionally, the airborne particles that cause acid rain can also contribute to smog. [7]

  9. Alkali soil - Wikipedia

    en.wikipedia.org/wiki/Alkali_soil

    The causes of soil alkalinity can be natural or man-made: The natural cause is the presence of soil minerals producing sodium carbonate (Na 2 CO 3) and sodium bicarbonate (NaHCO 3) upon weathering. Coal-fired boilers / power plants, when using coal or lignite rich in limestone, produce ash containing calcium oxide.
