Effects of Simulated Acid Rain on Soil Acidification in Different Fertilizing Conditions

By simulated acid rain experiment, the effect of acid rain of different pH values on soil acidification in different fertilizing conditions was studied. The results indicated that the leaching of acid rain led to increasing of latent acid of soil in short time though amortizing of soil to acid precipitation. With acid rain or normal rain leaching, the chemical fertilizer could result in decrease of pH value of soil, and chemical fertilizer and organic fertilizer could do so.
