Abstract：Soil acidification is a common problem in agricultural development.In order to understand the degree of farmland soil acidification and nutrient status in Zhumadian City,Henan Province,17 soil samples were collected from Runan County,Xiping County and Suiping County,soil pH value,conductivity,quick acting phosphorus content and alkaline dissolved nitrogen content were determined.The results showed that the pH value of farmland soil in Zhumadian City ranged from 4.07 to 5.64,the conductivity ranged from 108.73 to 604.33 μS/cm,the content of quick acting phosphorus ranged from 9.04 to 144.74 mg/kg,and the content of alkaline dissolved nitrogen ranged from 74.37 to 248.86 mg/kg.The farmland soil was seriously acidified,and the contents of salinity,quick acting phosphorus and alkaline dissolved nitrogen were low,which was not conducive to crop growth and development.The results can provide reference for further improvement of the soil environment.
