Description: This layer representing the Soil Salinity from 0 to 50 cm is a derived dataset from the Abu Dhabi Soil Survey Project 2009. Evaluation of salinity in the first and second 50cm of the soil horizon respectively was based on electrical conductivity of the soil. Electrical conductivity is a measure of the concentration of water-soluble salts in soils. It is used to indicate the soil salinity level. High concentrations of neutral salts, such as sodium chloride and sodium sulfate, may interfere with the absorption of water by plants because the osmotic pressure in the soil solution is nearly as high as or higher than that in the plant cells. Salts may also interfere with the exchange capacity of nutrient ions, thereby resulting in nutritional deficiencies in plants. The EC values measured by soil surveyors (EC 1:1) at each soil horizon at each field site were used to calculate an average EC value (weighted for horizon thickness) for the first two 50cm layers of soil at each site. That EC value was converted to ECe by multiplying by a factor of 3. These values were used to find the median ECe value for the 0-50cm layer and 50-100cm layer for each soil component. Use limitations The data must be used appropriately for the scale of mapping. Prior to decisions about land use more detailed site inspection is likely to be required to develop detailed understanding of soil and site characteristics related to the planned use.
