WebSoil pH is one of the key factors that affect soil microbial abundance. Wakelin et al. (2008) reported that variation in soil bacterial structure and catabolic function were significantly linked to soil pH alone, with a correlation coefficient of 0.604 and 0.722, respectively. Acidification of soils in organic farming significantly affects the ... WebWhen the pH of a soil is increased, the release of H from carboxyl groups helps to buffer the increase in pH and at the same time creates the CEC (negative charge). With an increase in organic matter, the soil recovers its natural buffer capacity; this means an increase in pH in acid soils (Figure 19).
