Progress in Selection and Application of Soil Improvement Materials for Acidic Farmland
There is a large proportion of acidic farmland in China,which is mainly distributed in the southern and the Bohai Bay areas with good light,mild and rain resources.The persistent acidification of soils has caused the decline of soil quality which affects food safety production and agricultural sustainable develop-ment greatly.Application of soil amendments is an efficient,economical and practical method for remediating acidified farmland soil and achieving nutrient utilization efficiency and green development.In this paper,the characteristics,effects and cost-effectiveness of soil amendments based on inorganic and organic materials on acidified soil improvement were reviewed,and the selection principle of materials suitable for acidic soil im-provement and the future development trend of soil amendments were analyzed,hoping to provide references for selection and development of soil amendments for acidic farmland.
