On the Characteristics of Leaching and Accumulation of Chemical Elements in Two Eutric Paddy Soils in Taoyuan County, Northern Hunan Province
The leaching and accumulation of chemical elements in the process of soil formation play an important part in revealing soil development and soil fertility. Based on the data obtained from the chemical determination of major and minor elements in two eutric paddy soil (No. s-48, s-76), and in comparison with the adjacent leached limestone soil (No. s-49) and leached purplish soil (No. s-47), a discussion is here made on the role of leaching and accumulation of the chemical elements in the formation of eutric paddy soils.
