The studies are based on the field vegetation experiment in the second, third, and fourth year after the acid rain sprinkling had been applied. Acid rains or liming were applied in the following doses: 30 and 60 kg S ha⁻¹ year⁻¹, 0,85 t CaO or 1,7 t CaO ha⁻¹. It was found that the sulphurisation added to brown soil and liming has strong after effect on the microbiological processes studies (amonifications, nitryfications, numbers of microorganizms).
