Abstract:

A field experiment was conducted in Central Anatolia, Turkey, with three different salinity levels of irrigation water (1.5, 3 and 4.5dS/m) and two leaching fractions (20 and 30 %) applied to a maize (Zea mays) plot and a control plot. Two different sets of inputs, one was normal measurements over a 2 year period and the other was for the effect of long-term rainfall leaching, were applied into the Watsuit simulation software. The resulting changes in actual soil salinity comprised vertical profile changes of actual EC (as well as SAR) were fairly stable, but with a slight tendency to increase with depth. In comparison model estimates of soil salinity (and SAR) were 20% (and 70%) more than the measured levels under the worst scenario. Thirdly a comparison of two year and estimated long term SAR values showed that as the SAR of irrigation water was higher than the soil, the values increased with time.
