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...
should be considered a long term project, rather than trying to accomplish it in one year. It is better to test your soil each year and make your adjustments gradually. The addition of hardwood ash, bone meal, crushed marble, or crushed oyster shells will also help to raise the soil pH....
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 ...
soil test should provide detailed instructions specific to your soil's needs. Generally, lime products such as ground limestone are used to raise the pH in very acidic soils, while sulfur products such as elemental sulfur are used to decrease soil pH. 如果分析显露它是必要的,调整土壤的酸碱度。
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, as well as pH increases during the incubation, make generalized conclusions untenable26,27. Attempts with...
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.PleasantBarbaraEBSCO_AspMother Earth News
Calculation of soil acidification rates requires knowledge of pH buffering capacity (pHBC), which is measured using titration methods. The pHBC is often quoted as a single value for a particular soil, implying a linear relationship between pH and the amount of acid or alkali added. However, over...
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 ...
If you have acidic soil, you do not have to spend a fortune on changing it. Simply plant any of these 43 acid loving plants. Soil which is below a 7pH, but ideally hanging out at around 5.5, could be great ground to grow an abundance of these delicious f
