Effects of inorganic and organic amendments on desalting and preventing alkalization in coastal salinized soils

Progress of research and utilization of soil amendments;

Latosol was treated with various soil amendments,and one year after the field trial it was determined in terms of soil cation exchange capacity,effective cation exchange capacity,soil exchangeable base-cation concentrations and base saturation to observe the effect of different soil amendments application on the latosol exchangeable property.

Bentonite, lime, filtered mud, goat dung, bagasse and green manure(stylo) were used as soil amendments to apply to marine deposit latosol in the field at Ongtian township, Wenchang, Hainan, China, and the active acidity and exchangeable acidity of the latosol were determined 1 year after soil amendments were applied.

Effect of several soil amendments on the growth characteristics of perennial ryegrass in the riverside of Yellow River;

A pot experiment with Brassica Parachinensis Bailey, Maize and a field experiment with Maize were carried out to prove the effect of a new type of granulated soil amendment from paper mill sludge compost.

In agricultural production, alkali lignin can be used as pesticide slow release agent to produce slow release fertilizer and soil amendment.

The result of field experiment uninterrupted for three years showed that:when soil modifier was applied,litchi yield increased clearly.

According to the problem of soil sourness in the South of China,in a pot experiment,8 kinds of soil modifier were selected as soil improvement measures.

Therefore,using of the combustion residue of a waste site as soil modifier would result in serious pollution of PCDDs/PCDFs in soil,which we believe should solicit attention from the related authorities.
