Study On Impact On Rules Of Migration And Transformation Of Nutrient Elements In Soil Environment By Acid Rain

Based on the fact that the serious air pollution in ShiJiazhuang lead to acid rain in some months and acid rain can affect nutrient elements in soil, this paper analyzed the soil environment, origin, formation and countermeasure of acid rain and did a deep research on its impact on nutrient elements in soil environment through rinsing experiment with different pH. The result showed that acid rain in Shi jiazhuang belongs to the type of sulphate; SO42- and fast acting Phosphorus both in brown soil and wet soil and fast acting Nitrogen in brown soil have close relationship with acid rain; The sensitive order of various salt kation to acid rain is Ca2+>Mg2+>Na+>K+; This paper also disclosed the rinse rules of migration of Nitrate nitrogen, fast acting Phosphorus, fast acting Potassium in the soil environment by acid rain; This paper can provide scientific basis for protection of soil environment.
