The Influence of Long-Term Fertilization on Soil Acidification

Abstract

Based on the long-term experimental field of Jilin Agricultural University as a platform. Aiming at groping for the influence of long-term fertilized of the acidity changes on soil in research area. The results show that: compared with CK group. The soil pH declined as a result of applying nitrogenous fertilizer chronically. Instead the content of exchangeable acid, exchangeable hydrogen and exchangeable aluminum increased. The content of soil organic matters reduced with the decrease of soil pH application of phosphate fertilizer and potassium fertilizer could achieve the same objective. But the Influence was not as significant as the one fertilized with N.
