- Abstract:
- Chemicals’ transport in soils can be influenced by some soil factors,such as soil moisture, texture, homogeneity and soil temperature.The influence of the texture and the bulk density on chemicals’ transport under the laboratorial conditions are studied. The result is that the value of the hydraulic dispersion coefficient (D) in loessal soil is greater than that in aeolian sandy soil because of the relatively high content of clay compared with aeolian sandy soil, but the value of the retardation factor in loessal soil is smaller than that in aeolian sandy soil; and that the value of D become smaller and smaller with the bulk gravity decreasing and the value of R increased gradually.
