Effectiveness of spectral data reduction in detection of salt-affected soils in a small study area
Data reduction is used to aggregate or amalgamate the large data sets into smaller and manageable information pieces in order to fast and accurate classification of different attributes. However, excessive spatial or spectral data reduction may result in losing or masking important radiometric information. Therefore, we conducted this research to evaluate the effectiveness of the different...
متن کاملRECLAMATION OF SOME SODlC SOILS BY THE HIGH SALT WATER DILUTION METHOD
, Abstract Results of the laboratory reclamation of four sodic soils by the high salt water dilution method are reported. The exchangeable sodium percentage (ESP) of all soils was decreased by leaching with solutions of decreasing sodium but constant calcium concentration. Although a final leaching with water of low electrolyte concentration (EC,, < 100 micromhos/cm) did not produce a rapid dec...
متن کاملThe Effect of reclamation of salt affected lands to Cropland on soil quality indicators
In this study the effects of land use change from salt affected land to cropland on soil quality indicators were studied in Chahafzal region, Yazd province, central Iran. Composite soil samples from 0-30 and 30-60 cm depths of saline and cultivated land were taken. Soil particle size distribution, calcium carbonate, Available water capacity (AWC), Electrical conductivity (ECe), Soil reaction (p...

متن کاملExperimental infection with western equine encephalomyelitis virus in wild rodents indigenous to Kern County, California.
Six species of rodents from Kern County, California, were inoculated subcutaneously with western equine encephalomyelitis (WEE) virus to determine their susceptibility to infection and their potential as natural hosts. Ammospermophilus nelsoni, Citellus beecheyi, Dipodomys heermanni, Dipodomys nitratoides, Peromyscus maniculatus, and Sciurus griseus were readily infected. Infection was usually ...
