Salt-affected soils in Argentina

Maps of pH on water, electrical conductivity (dS/m), exchangeable sodium percent (%) and soils affected by salts in Argentina at different depth intervals (0-30 and 30-100 cm) at 1000 m resolution. Including the tree standard layers and error estimation using random forest. Global accuracy based on cross-validation. <strong>sp</strong> <strong>RMSE</strong> <strong>Rsquared</strong> <strong>EC (dS/m) 0-30 cm</strong> <strong>5.53</strong> <strong>0.134</strong> <strong>EC (dS/m) 30-100 cm</strong> <strong>5.77</strong> <strong>0.208</strong> <strong>pH on water 0-30 cm</strong> <strong>0.84</strong> <strong>0.456</strong> <strong>pH on water 30-100 cm</strong> <strong>0.80</strong> <strong>0.523</strong> <strong>Exchangeable sodium percent (%) 0-30 cm</strong> <strong>13.08</strong> <strong>0.169</strong> <strong>Exchangeable sodium percent (%) 30-100 cm</strong> <strong>15.40</strong> <strong>0.187</strong>
