Irrigation Water Quality Index. Respect to water quantity and quality. There are gentle differences between these methods and WQI based method was employed by WHO. The values fall within the Third category of 0 25 irrigation water. Water tem-perature dissolved oxygen pH biochemical oxygen demand nitrate phosphate turbidity total solids and fecal coliforms.
The assessment of water quality suitability for irrigation was carried with the help of indices like Sodium Absorption Ration Soluble Sodium Percentage Residual Sodium Carbonate 11 Schoeller Index 8 and Kellys Index 5 also converting. Irrigation water quality The water quality used for irrigation is essential for the yield and quantity of crops maintenance of soil productivity and protection of the environment. Soil structure stability of aggregates and permeability are very sensitive to the type of exchangeable ions present in irrigation waters. 1970 and consists of a weighted average index of nine parameters of water quality. High pHs above 85 are often caused by high bicarbonate HCO. The acidity or basicity of irrigation water is expressed as pH 70 acidic.
1970 and consists of a weighted average index of nine parameters of water quality.
The quality of the irrigation water. Water quality indices provide a simple and understandable tool for managers on the quality and possible uses for irrigation water. The Residual Sodium Carbonate RSC values ranges between 516 and 1057 with an average of -145 which agrees with less than 25 specified for the purpose of irrigation. It may be defined as a rating reflecting the composite influence of different water quality parameters on the overall quality of water. Soil structure stability of aggregates and permeability are very sensitive to the type of exchangeable ions present in irrigation waters. Water quality indices analysis.
