文摘The formation of soil structure is mainly dependent on the dispersion and aggregation of soil colloids, and it has a close connection with varieties of cations adsorbed to soil, saturation and organic matters. It has been found that there are a great number of Ca and Na ions in comparison with others adsorbed on chernozem and yellow brown earth.
