Abstract

Abstract: The impact of acidified soil and the subsequent effects on terrestrial ecosystems has raised public concern and become a hot research topic over the past decade. From 2002 to 2004, a systematic soil geochemical survey was conducted with the aim of studying the changing trend of the soil chemical elements in the catchment area of Liaohe in Liaoning Province. The results showed that the pH is unaffected by acid inputs when CaO+K₂O concentration in soil is more than 3.86%, which may buffer against the acidity inputs, whereas the soil pH drops rapidly when CaO+K₂O concentration in soil is lower than 3.86%. A map of buffering ability was developed, and it predicted that the soil in the eastern region of Liaohe catchment is much more vulnerable to further acidification. We then discuss the effects of increased Cd leaching upon soil acidic processes, biogeochemical processes, areas susceptible to Cd in rice and maize seeds are manifested.

Key words: soil acidification, cadmium, staple crops, geochemical early warning, catchment area of Liaohe
