Effects of applying flue gas desulfurization gypsum and humic acid on soil physicochemical properties and rapeseed yield of a saline-sodic cropland in the eastern coastal area of China

摘要

Soil salinization is considered as the most important abiotic stress limiting crop production and degrading soil properties. The purpose of this study was to investigate the effects of applied flue gas desulfurization (FGD) gypsum and humic acid on the amelioration of coastal saline-sodic soil and their influence on rapeseed yield.
