Nitrification was much slower in five strongly acid (pH 4.0–4.3) soils from tea plantations in Sri Lanka than in a near-neutral grassland soil from the U.K., suggesting that the nitrifiers in these tea soils are close to the lower limit of their pH range. Nitrapyrin effectively inhibited nitrification in all the soils: dicyandiamide was less effective. Low concentrations of KC1 slowed nitrification in the acid tea soils but not in the near-neutral grassland soil. The concentrations of KC1 used (up to 20 mM) were sufficient to cause measurable decreases in soil pH in both acid and neutral soils. It is proposed that this salt-induced decrease in pH is detrimental to nitrifying organisms operating at the limit of their pH range but not to nitrifiers nearer their pH optimum.
