Determination of suitability of water quality for agricultural purposes using new scoring based Randev and Puri classification

Abstract

To determine the suitability of water for various purposes such as agriculture, domestic and drinking, different classification methods has been developed over the time. Each classification system use few parameters to determine suitability of water quality for different purposes. New scoring based Randev and Puri classification was developed to determine suitability of water quality for irrigation purposed, because it was noted that most of classification uses just one or two parameters. On the basis of one or two parameter, it is not possible to present overall estimation of water quality. In this system, water quality was classified on the basis of well-known ten classifications (total hardness, electrical conductivity, total dissolved solids, sodium absorption ratio, magnesium hazard, Kelley’s ratio, soluble sodium percentage, sodium absorption ratio, Stuyfzand’s classification, United Stated soil laboratory) and then score were provide to each class in different classification. Than overall scores were calculated and on the basis of these scores final class of water quality was determined.
