摘要
一般范围内的酸沉降对热带土壤酸化的影响不大,但有机质含量出现一定程度的下降。阴离子态营养元素N、P、S的有效性提高,但阳离子态营养元素Ca、Mg、K等的供应水平降低,土壤交换性能的质量下降。
The acid precipitation of pH>3.0 haven′t remarkable contributions to the acidification of tropical soils. However, the contents of organic matter in soils decrease in varying degrees. The availabilities of anion nutrient elements N, P, S are increased after the acidic leaching. But the contents of cation nutrient elements such as Ca, Mg and K are reduced.
