WebSoil acidity and high cation exchange capacity contributed to high concentrations of AlKCl in the soil, whereas high base saturation and total C had the opposite effect. Total N decreased with increasing AlKCl in the topsoil (0–20cm), which is likely a response to the effects of Al toxicity on biological N fixation by pasture legumes. WebThis type of acidity is obtained by extracting soil with a neutral salt such as KCl. Neutral salt does not react with water, so it does not affect soil pH. Exchangeable Al 3+ and H+ are replaced by cations of the neutral salt and then they are titrated with a base. Al 3+ + OH-Al(OH)3 solid acid-base neutralization reaction. H+ + OH-H2O water
