This compound causes rainfall pH to be around 5.0–5.5. When rainfall has a lower pH than natural levels, it can cause rapid acidification of soil. Sulfur dioxide and nitrogen oxides are precursors of stronger acids that can lead to acid rain production when they react with water in the atmosphere.
The plant is called wild ginger because the rhizomes and leaves taste and smell similar to ginger root, but the two are not particularly related. The FDA warns against consuming Asarum, as it is nephrotoxic and contains the potent carcinogen aristolochic acid. [1] [2] [3] The birthwort family also contains the genus Aristolochia, known for ...
Effect of soil pH on cation-exchange capacity. The amount of negative charge from deprotonation of clay hydroxy groups or organic matter depends on the pH of the surrounding solution. Increasing the pH (i.e. decreasing the concentration of H + cations) increases this variable charge, and therefore also increases the cation-exchange capacity.
Asarum canadense, commonly known as Canada wild ginger, Canadian snakeroot, and broad-leaved asarabacca, is a herbaceous, perennial plant which forms dense colonies in the understory of deciduous forests throughout its native range in eastern North America, from the Great Plains east to the Atlantic Coast, and from southeastern Canada south to around the Fall Line in the southeastern United ...
Then, using the initial soil pH and the aluminium content, the amount of lime needed to raise the pH to a desired level can be calculated. [68] Amendments other than agricultural lime that can be used to increase the pH of soil include wood ash, industrial calcium oxide , magnesium oxide, basic slag (calcium silicate), and oyster shells.
Measured on the pH scale, soil acidity is an invisible condition that directly affects soil fertility and toxicity by determining which elements in the soil are available for absorption by plants. Increases in soil acidity are caused by removal of agricultural product from the paddock, leaching of nitrogen as nitrate below the root zone ...

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.
