Summary
The composition of alkaline – earth alkaline ions in surface layer of rice field in the Red River delta – northern Vietnam
The alkali ion concentration adsorbed on soil particle of Nam Dinh saline soil and Hai Phong acid sulphate soil have been clarified. It is reported that sodium adsorption was the main reason for salinity I the same soil, but it may not true in the acid sulphate soil. As result, it needed to carry out a further study about this topic in order to find out the optimal way to use the natural resource in the salt-effected soil area of the Red River delta.
