Soil Quality and Water Redistribution Influences on Plant Production over Low Hillslopes on Reclaimed Mined Land

Table 4

(a) Correlations between distance from bottom (toe) of hillslopes and water redistribution index (WRI), respread soil depth (RSD), and soil quality index (SQI). (b) Correlation matrices for WRI, RSD, and SQI. (c) Correlations between SQI and soil properties. All values given have . AWC, available water content; EC, electrical conductivity; P, available phosphorus; SAR, sodium adsorption ratio; SOC, soil organic carbon.
