Salt-affected soils in Argentina

<p>&nbsp;</p> <p>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)&nbsp;at 1000 m resolution.&nbsp;Including the tree standard layers and error estimation using random forest. Global accuracy based on cross-validation.</p> <table> <tbody> <tr> <td> <p><strong>sp</strong></p> </td> <td> <p><strong>RMSE</strong></p> </td> <td> <p><strong>Rsquared</strong></p> </td> </tr> <tr> <td> <p><strong>EC (dS/m) 0-30 cm</strong></p> </td> <td> <p><strong>5.53</strong></p> </td> <td> <p><strong>0.134</strong></p> </td> </tr> <tr> <td> <p><strong>EC (dS/m) 30-100 cm</strong></p> </td> <td> <p><strong>5.77</strong></p> </td> <td> <p><strong>0.208</strong></p> </td> </tr> <tr> <td> <p><strong>pH on water 0-30 cm</strong></p> </td> <td> <p><strong>0.84</strong></p> </td> <td> <p><strong>0.456</strong></p> </td> </tr> <tr> <td> <p><strong>pH on water &nbsp;30-100 cm</strong></p> </td> <td> <p><strong>0.80</strong></p> </td> <td> <p><strong>0.523</strong></p> </td> </tr> <tr> <td> <p><strong>Exchangeable sodium percent (%) 0-30 cm</strong></p> </td> <td> <p><strong>13.08</strong></p> </td> <td> <p><strong>0.169</strong></p> </td> </tr> <tr> <td> <p><strong>Exchangeable sodium percent (%) 30-100 cm</strong></p> </td> <td> <p><strong>15.40</strong></p> </td> <td> <p><strong>0.187</strong></p> </td> </tr> </tbody> </table>
