Abstract
The effect of acid rain and N fertilizer variety on leaching loss of NO_3~--N in purple soils has been studied by soil columns experiments. The results show that acid rain and N fertilizer variety affect leaching loss of NO_3~--N. To the neutral soil, the effect of pH on leaching loss of NO_3~--N is obvious,as follows:the lower the pH, the stronger the leaching loss of NO_3~--N;to the acidic soil is not very obvious.On the condition of the same of pH and different fertilization, the sequence of the leaching loss of NO_3~--N is:Organic manure+ FertilizerFertilizerOrganic manureControl treatment.
