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...
Acidic soil is any soil with a pH balance below 7. Soils that are below 7 are acidic while those with a pH balance above 7 are considered to be alkaline. Knowing the pH balance of the soil is important because certain plants and crops grow best in a certain type of soil. The pH ...
Thus, soil acidification of CECt due to net losses of BC could not explain differences in soil pH and %BS among the soil profiles. A weak acid analogue, taking the pH-effect of metal complexation into consideration, combined with soil solution ionic strength as a covariate, could describe ...
march 26, 2025 acidic soil may seem like the be-all to end-all of plant growth, but it has unique characteristics that don’t necessarily mean a death sentence for your yard. controlling ph levels is extremely important for healthy plant development. soil tests, amendments, and care are ...
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 ...
microcosms with pH values below 520,24,25; however, soil heterogeneity and associated microscale patchiness of pH conditions, as well as pH increases during the incubation, make generalized conclusions untenable26,27. Attempts with denitrifying enrichment and axenic cultures derived from soil have thus...

Acidic Typic Cryoboralf soils amended with wood ash can raise soil pH and can supplement plant growth by adding minerals and micronutrients. However, presence of other elements in soils such as Cd, S, and Zn can affect plant growth and seed quality. In an earlier paper, we have shown ...
which regulates the abundance of AOA and AOB and their nitrifying ability. The soil environment rather than AOA or AOB could control nitrification in long-term fertilized farmlands with a pH below 4. These findings could improve fertilization efficiency and control nutrient runoff in hilly agricultural...
