Abstract

Through soil columns leaching, the effect of different simulated acid rain on the leaching amount of phosthorus in Chongqing grey purple soil with different fertilizers was investigated. The leaching amount of phosthorus in the soil changed with the acidity of simulated acid rain and generally was in an order: LpH5.5LpH4.5LpH3.5LpH6.5. Fertilizer kinds, including chemical, organic or mixed fertilizer, also influenced the leaching characteristics of the soils. More phosphorus leaching was found in the soil applied chemical or mixed fertilizer than that in the soils without chemical or mixed fertilizer.
