Effect of Suplhur in Rainfall, Irrigation Water and Percocolating Water on Soil Sulphur in Jiangxi Province

摘要

Ten rainfall and irrigation water-collecting posts were set up in different ecotype districts of Jiangxi Province, China, to quarterly measure S content in rainfall and irrigation water. A rainater chemical composition-collecting device was used to collect the sulphur in rainfall, and the amount of sulphur adsorbed on the resin column in the device was determined. The soil percolating water was gathered using a 6 lysimeters, built up according to the profile sequence of the red soil derived from red sandstone and the red soil derived from Quaternary red clay, separately.
