Oxygen consumption as a measure of metabolic processes in the soil, ma
intained in a bare fallow state, was considered as an indicator of soi
l degradation under the influence of acid rain. This paper summarizes
the results of experiments, both field and laboratory, with simulated
acid precipitations. The reaction of soil aerobic metabolism proved as
sensitive to the impact of acid introduction as the change in soil pH
which had appeared earlier. The lowering of the metabolic rate is how
ever not directly proportional to progressive soil acidity.
