Abstract

To provide a reference for coastal saline soil improvement，an experiment with pig slurry amendments from coastal saline soils was conducted to determine the effects on content and particle fractionation of organic carbon and to demonstrate the accumulation and evolution law of soil organic carbon. Results showed that soil total organic carbon（TOC） and carbon content for different sized soil particles decreased with an increase of soil profile depth and increased with the length of time that pig slurry amendment was used. Also，soil carbon consisted mainly of silt carbon. In natural fallow land TOC was 8.90 - 14.40 gkg-1，and on fertilized land it was 5.45 - 13.55 gkg-1. Thus，both natural fallow and pig slurry amendments could improve TOC and carbon from different sized soil particles in coastal saline soils，thereby improving their quality.［Ch，1 fig. 2 tab. 16 ref.］
