Indicators of soil acidification were studied in the group of Cambisols at the Kysuce region. Separation of soil aggregates into the core and surface according to Kayzer and Wilcke was used as the method. Direct and undirect indicators were determined. Acid load caused that surface of soil aggregates is acidified preferably what reflected in the lower pH/CaCl2 values in comparison with pH/CaCl2 values of core of aggregates. Cd, Pb input into the soil through the acid-metal load is adsorbed on the surface of aggregates and additionally Cd, Pb penetrate into the plant - oat (Avena sativa): root (average content of Cd 0.66 mg/kg, average content of Pb 10.42 mg/kg), straw (average content of Cd 0.06 mg/kg, average content of Pb 0.37 mg/kg), grain (average content of Cd 0.15 mg/kg, average content of Pb 0.51 mg/kg). The limit set up for food was over for Cd in the 46%, for Pb in 9%
