WebOct 2, 2024 · ABC and ABC/P are relatively alkaline and can also increase soil pH by increasing soil base saturation, reducing exchangeable aluminum levels, and consuming soil protons. On the other hand, the soil cation exchange capacity (CEC) is an important basis for evaluating soil fertility retention, soil improvement and rational fertilization [ 21 ]. WebApr 13, 2024 · Alkalinity is primarily found as carbonate (CO 3 2−) and hydroxide (OH) salts above pH 8.3. Alkalinity is mostly found as bicarbonate (HCO 3) salts between pH 4.5 and pH 8.3. At pH 4.5, these salts’ buffering capacity is depleted, and it is almost completely converted to carbonic acid (H 2 CO 3). The different alkalinity constituents are ...
