Abstract
INCUBATION investigations of the metabolisms of ammonium sulphate added to soils of Colombia (South America) showed that not all the added nitrogen could be accounted for by the usual metabolic processes (nitrification, nitrogen immobilization, etc.). Further work showed that significant amounts of ammonia were being evolved from these soils. Volatilization of ammonia was relatively high from soils of pH. of about 7 or greater, as shown by other workers1–3, but significant volatilization occurred even from six acid soils (pH 4.8–6.3).
