Title: Reclaimed Soil Fertility and Its Response to the Physical-Chemical Properties in Fly Ash Disposal Sites
Abstract: The reclaimed field of fly ash disposal sites was selected as the research area in Shaoyao,Huainan.The cover soil thickness,some soil physico-chemical properties(bulk density,water content,pH and organic matter),soil nutrients(total nitrogen,available phosphorus and available potassium) and winter wheat biomass in heading stage were determined,and the correlation of the reclaimed soil physico-chemical properties and its nutrient was analyzed in fly ash disposal sites.The winter wheat growth differences were also studied under different coversoil thickness conditions.The results showed that the total nitrogen content was about 900 mg/kg in reclaimed soil of fly ash disposal sites,the content of available phosphorus and available potassium was 12-76 mg/kg and 114-135 mg/kg respectively.The soil fertility and crop growth conditions were not significant difference with natural agricultural soils.The available phosphorus content and reclaimed soil bulk density,water content had a significant correlation.In addition,the response relationship between the reclaimed soil fertility and its properties,topsoil thickness was not obvious.
