Abstract
The USSR classifications of soil salinity used in Central Asiawas based on laboratory measurement of the total dissolved(toxic) salts or the chloride ion concentration in the soil waterextracts (soil:water = 1:5). Current practices, however, startto differ between the republics because of different levels ofacceptance of international literature. This change in practiceis triggered partly by the cost of the laboratory measurements.The use of different methods next to each other affects thereliability of information on salinity. This paper promotes theused of the UC of a 1:1 soil-water suspension was found to givethe best fit to the soil extract with leaching of calcium andsulfate ions. The cost of data collection is significantly lowerthan that of the 1:5 extract.
