酸性土壤（Acidic soil）是指土壤的 pH 值低于 7 的土壤，通常 pH 值在 5.5 以下。酸性土壤含有过多的酸性离子和少量的碱性离子，这些离子包括硫酸、硝酸、氯化物、氢氟酸等。这些酸性离子在土壤中堆积过多会导致土壤酸化，使植物无法正常生长。酸性土壤会对植物的生长和发育产生负面影响，主要表现在以下几个方面...
The definition of pH, its significance to soil and plants are mentioned. Moreover, ways of testing the pH balance of soil, adding compost and lowering the alkaline soil's ph are also stated.PleasantBarbaraMother Earth News
and acidic environments are generally considered N2O emitters19,20,21,22,23. A few studies reported N2O consumption in denitrifying soil (slurry) microcosms with pH values below 520,24,25; however, soil heterogeneity and associated microscale patchiness of pH conditions...

In acidic soil P availability for plant uptake decreases due to P fixation with acidic cations such as Al and Fe21, which reduces the plant P uptake. Use of different organic and inorganic amendments has been reported in previous studies to enhance soil pH and PUE22,23. In a previous ...
An acidic substance would have a pH of less than7. A pH of 7 is considered neutral, and pure water has a pH of 7. A solution that has apH of less... Learn more about this topic: The pH Scale | Definition, Equation & Examples ...
A typical example is the condensation of acidic gases inside a metal flue when the temperature is allowed to fall below the dew point of the contained gas; firing with heavy fuel oils or sulfite residues can be particularly troublesome, and special attention should be paid to vulnerable areas ...
Poplars (Populus trichocarpaTorr. & A.Gray ex Hook.,Populus maximowicziiA.Henry and their hybrids) are known to be nutrient and water demanding and require a soil pH > 5 for optimal growth; below this, growth reductions are common due to nutrient limitations and increased susceptibility ...
