The Effects of Land Use and Landscape Position on Soil Physicochemical Properties in a Semiarid Watershed, Northern Ethiopia

Figure 7

Pearson’s correlation matrix graph for selected soil physicochemical properties of the Ayiba watershed, northern Ethiopia (note: the correlation matrices present lower left in color and p values in asterisk and upper right in number (sampling depth 30 cm, n = 30). Positive correlations are displayed in blue, and negative correlations are in red color. Color intensity is proportional to the correlation coefficients, and , , and indicate significance at  < 0.05,  < 0.01, and  < 0.001, respectively).
