Południowopodlaska Lowland ecosystem soil buffer capacity

The paper presents the results of research on soil buffer capacity in Południowopodlaska Lowland ecosystems. The buffer curves were sketched and soil buffer areas measured with planimeter. The data obtained were compared with some soil physical and chemical properties using statistical methods. The greatest acid buffer capacity was observed in highly base-saturated meadow ecosystem soils (VCEB = 82.8 - 98.7%), while the greatest alkali buffer capacity low base-saturated soils of forest ecosystems (VCEB = 10.8 - 49.5%). Upper horizons of arable land soils showed a greater alkali rather than acid buffer capacity, while soil buffer capacity of deeper mineral horizons changed with soil physical and chemical properties.
