Abstract:
This data contains measured soil indicators of salt-affected soils in northern Sudan. The soil indicators are electrical conductivity (EC), pH, exchangeable sodium percent (ESP). The data is from 318 locations and were collected between January and August 2018. Each location was sampled at varying depths between 0 and 200 cm and the samples analysed in the laboratory for EC (dS/m), pH, and ESP. Laboratory analyses were done using the saturated soil paste extracts approach. pH was determined using glass electrode while EC was determined using digital EC-meter. ESP was calculated from measured exchangeable sodium ions and cation exchange capacity
