Tanghai County, the city from 1964 onwards, with nitro humic acid salinization to achieve better results and caused the attention of all relevant departments. In the past 40 years, Hebei Institute of Rice Research has used humic acid fertilizer to transform saline-alkali soil so that a large amount of experimental popularization work has been done and completed the scientific research project of “humic acid transformation saline-alkali land” issued by Bureau of Comprehensive Utilization of Coal Industry.
