土壤酸化过程的土壤化学分析

Soil Chemical Analysis on the Process of Soil Acidification.

要了解自然的抑或农业的土壤生态系统,认识和研究土壤酸化过程是必要的。土壤酸化过程在自然界是固然存在的。

Some important items and controlling factors involved in the process of soil acidification are discussed in this paper.Soil acidification,as reflected by alkali neutralizing capacityand pH,may be affect(?)d by atmospheric acid deposition,which is companied by the accelerated leaching loss of base cations,lowering of pH and mobilization of aluminum to formhydroxyl aluminum suflate minerals.Two parameters △M/△H and △pH/△H may be used asvalid indices for evaluating the soil responses to atmospheric acid deposition.
