  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

    Use of an inexpensive pH testing kit, where in a small sample of soil is mixed with indicator solution which changes colour according to the acidity. Use of litmus paper. A small sample of soil is mixed with distilled water, into which a strip of litmus paper is inserted. If the soil is acidic the paper turns red, if basic, blue.

    soil acidification - reduction in pH, usually in soil. Acidification can result in poorly structured or hard-setting topsoils that cannot support sufficient vegetation to prevent erosion. soil bulk density – the relative density of a soil measured by dividing the dry weight of a soil by its volume. soil compaction – the degree of ...

  5. Soil conservation - Wikipedia

    en.wikipedia.org/wiki/Soil_conservation

    The rows formed slow surface water run-off during rainstorms to prevent soil erosion and allow the water time to infiltrate into the soil. Soil conservation is the prevention of loss of the topmost layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination

  6. 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]

  7. 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

  8. Topsoil - Wikipedia

    en.wikipedia.org/wiki/Topsoil

    Intensive farming methods to satisfy high food demands with high crop yields and growing crops in monocultures can deplete the soil nutrients and damage the soil microbiome. These factors can affect the consistency and quality of the soil resulting in increased erosion. Surface runoff from farm fields is a type of nonpoint source pollution.

  9. Land degradation - Wikipedia

    en.wikipedia.org/wiki/Land_degradation

    All are induced or aggravated by human activities, e.g. soil erosion, soil contamination, soil acidification, sheet erosion, silting, aridification, salinization, urbanization, etc. A problem with defining land degradation is that what one group of people might view as degradation, others might view as a benefit or opportunity.
