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. If the leaves are green and ...

[1] It has received some attention in the lay community, and has been used to support the diet known as the Alkaline diet . [ 1 ]

[33] Acidic foods, such as citrus fruits, tomatoes, and vinegar, typically have a pH below 4.6 [34] with sharp and tangy taste, while basic foods taste bitter or soapy. [35] Maintaining the appropriate pH in foods is essential for preventing the growth of harmful ...
Many soil fungi, although not all of them, acidify the soil by excreting oxalic acid, a product of their respiratory metabolism. Oxalic acid precipitates calcium, forming insoluble crystals of calcium oxalate and thus depriving the soil solution from this necessary element. [62] On the opposite side, earthworms exert a buffering effect on soil ...
