- Abstract:
-
The effect of 3 typical water and soil conservation methods (soil and water conservation forest, horizontal terrace, and terrace botanical zone) on soil total nitrogen (TN) and total phosphorus (TP) had been systematically studied in Huanren Hun River Basin, and the slope cropland was used as a control. The experiment was performed from March to September, 2013. More than 336 typical soil samples were collected and analyzed. It was found that TN and TP of soil samples collected from the area protected by the above 3 typical soil and water conservation methods were significantly higher than those collected from the slope cropland without any protection of the conventional soil and water conservation method. The TN and TP of the soil samples collected from horizontal terrace were 24.6% and 35.7% higher than those collected from the slope cropland, and the soil TN and TP from the terrace botanical zone were 19.4% and 37.4% higher, accordingly. The more dramatic effect was observed from simultaneously deploying 3 typical water and soil conservation methods together, the TN and TP of the soil samples were 29.2% and 30.6% higher, respectively, than those of the control samples. The research can provide the scientific guideline and feasible methods for the control of non-point source pollution of the sloping cropland.
