Soil Buffer Capacity
Soil buffering capacity refers to a set of properties determining its barrier function, which regulates levels of secondary contamination by chemical substances in media contacting the soil: vegetation, surface and groundwater, atmospheric air. The main components of soil creating buffering capacity are fine-dispersed mineral particles defining its mechanical composition, organic matter (humus), as well as medium reaction - pH
