Well Waters of the Regional Agricultural Research Station, Tindivanam Their Suitability for Irrigation

Abstract

The quality of irrigation water is determined by four factors: viz., composition and concentration of soluble salts, nature of the soil to be irrigated, nature of the crop to be grown and the climate of the locality. Eaton (1950) classified irrigation waters into three classes: viz. suitable, marginal and unsuitable based on the excess of carbonates and bicarbonates over the lime content. The workers of the United States Salinity Laboratory (1954) proposed certain standards. for judging the irrigation suitability of a given water based on its electrical conductivity and sodium adsorption ratio. Quite recently Subramani and Varma (1969) developed a numerical rating for evaluating the quality of irrigation water taking into considration the soil and crop characteristics also. A quality appraisal of the irrigation waters of the farm based on the above recent concepts has not been made so far which at the same time is an important information. Hence, an attempt has been made in this paper to collect the quality data of the well waters of the station at a time when they were fully used for irrigation and interpret them with respect to their irrigation suitability.
