Effect of special soil amendment for improvement of saline soil in northern Yinchuan of Ningxia
摘要
Abstract
A field experiment was conducted to analyze the effect of special soil amendments in improving saline soil in northern Yinchuan of Ningxia. The results indicate that applying special soil amendments can decrease soil bulk density by 6.44% and increase porosity by 6.62%; decease soil clay and increase silt and sandy content; decrease soil pH and total saline, improve soil organic matter, nutrients content and yield significantly. The effect of amendment IE is the best method in improving physical and chemical properties of saline soil. However, the general economical benefit of special soil amendment II is the highest when the cost of soil amendments is considered.关键词
