Salination of soil by salts in the irrigation water

This paper is a partial report on the quality of irrigation water. It is principally concerned with the salts of irrigation water which form salines in the soil. A method has been suggested for calculating the potential salinity of water and listed as ‘effective salinity.’ New conversion factors have been listed for changing from milliequivalents to parts per million or pounds of salt per acre foot for the soluble salts of effective salinity. A new standard has been suggested for the total salts of irrigation water based on the effective salinity, followed by a discussion concerning the application of this standard to irrigated agriculture.
