Abstract

In arid area such as, Iran rainfall is low and evaporation is high. Therefore, accumulation salts on the surface of soil in these areas are unavoidable. For that reason application, practical method for determination water requirement for reclamation soil is necessary.The primary aim of this study is to evaluate mathematical models of DESALINIZATION in two zones of northeastern KHUZESTAN province (southwestern Iran) without the use of a SOIL AMENDMENT. At each experimental site, were applied four LEACHING-depth treatments (25, 50, 75 and 100 cm of water) and two soil-amendment treatments (with and without sulfuric acid), for a total of eight treatments, in one-meter-square plots. Also, were established four replicate plots of each treatment. Before and after each LEACHING, were collected soil samples every 25 cm from the surface to a depth of 150 cm and were measured the electrical conductivity of each sample. Then11 mathematical models were developed using SPSS 12.0 software. In each model, the ratio of the net depth of irrigation to soil depth was used as the independent variable (X), while the ratio of the difference between the final electrical conductivity and the equivalent electrical conductivity to the difference between the initial electrical conductivity and the equivalent electrical conductivity was used as the dependent variable (Y). Statistical analysis of these mathematic models indicates that in zone one and two, the cubic equation is the best and the s equation is the worst equation for DESALINIZATION. In addition in these regions the cubic equation is the best and the logistic equation is the worst for desodification. Generally, the cubic equation obtained here can be generally applied to determine the appropriate LEACHING depth in the Shavoor plain in northern KHUZESTAN province, southwestern Iran.
