Soil salinization is a kind of soil degradation with global impact，which has a greatly negative impact on agricultural production，such as tillage difficulty and crop yield reduction.Organic materials，as a kind of recyclable resource with less side effects，are a relatively effective remediation method applied to improve saline soils.This review summarized that how different organic materials(manure，plant residues，social by-products and processed products，etc.)influence the improvement effect of saline soils，including specific responses in terms physical properties(soil bulk density，permeability，porosity，etc.)，chemical properties(soil nutrients，pH value，cation exchange capacity，etc.)and biological properties(microbial activity，enzyme activity，biological abundance，etc.).In order to further improve saline soils and prevent soil degradation，this paper reviewed the specific improvement effects of different organic materials on saline soils and summarises the use of some materials，with a view to providing some theoretical basis for subsequent research on saline soils improvement.
