Effect of acid precipitation on leaching of nutritionsand aluminium from forest soils

This paper principally deals with the effect of acid precipitation accelerating nutrients. such aspotassium, sodium, calcium, magnesium. leached out of forest soils and noxious element-aluminium releasedfrom soils on the basis of the result from leaching experiment of forest soils collected from southern and southwestern China under artificial rain of different acidity, PH 3. 5 , 4. 0 - 4. 5 - 5. 0 and 5. 6. It was discussedthat the released amount of nutrient elements and aluminiurn was related to physicochernical properties ofsoils, leaching volume and the acidity of artificial rain. respectively. The buffering capability generated by theelements releasing from soils against acid precipitation was discussed.
