A Comparative Study of Physicochemical Properties Previous and after Remediation of Contaminated High-sulfur Soil in Huanjiang

In 2001,the Huanjiang suffered heavy rain makes the fall of tailings, so Huanjiang river basin along the farmland is heavily polluted. The study focuses on the contaminated high sulfur polymetallic soil of Huanjiang, and conduct a preliminary evaluation on it. According to the pre-collection, the experiment adopt a total of 54 samples, analysis the pH, density, organic matter, available phosphorus, total phosphorus, nitrogen, potassium, and nutrients preliminary of the soil. The data shows that thesoil remediation pH, density, organic matter, available phosphorus, total phosphorus, nitrogen and total potassium mean were 6.15,1.56g/cm329.60g/kg, 9.54mg/kg, 0.57g/kg, 87.724mg/kg, 12.43g/kg respectively, Coefficients ofvariation were15%, 15.5%, 80.61%, 42.23%, 84.73% , 16.6% respectively.however, the pH, density, organic matter, nitrogen, available phosphorus mean of were6.15, 1.56g/cm3, 29.60g/kg, 9.52mg/kg, 0.57g/kg , 84.724mg/kg , 12.43g/kg. The results showed that various nutrients in the soil is still insufficient, and the spatial distribution of the difference. To ensure the growth of crops and harvest, Should be noted that in the process of planting fertilizer applied.
