WebJul 1, 2024 · Soil base cations (Ca 2+, Mg 2+, Na +) decreased while non-base cations (Al 3+, Fe 3+) increased with soil acidification. Soil respiration, fine root biomass, microbial biomass carbon and nitrogen were significantly reduced by 14.7%, 19.1%, 9.6% and 12.1%, respectively, under acid addition. WebSoil pH of 6.5 is usually considered optimum for nutrient availability. Lower pH increases the solubility of Al, Mn, and Fe, which are toxic to plants in excess. A critical effect of excess soluble Al is the slowing or stopping of root growth. Extreme pH values decrease the availability of most nutrients. Low pH reduces the availability of the ...
