DURSUN, Seyit Ali | MİKAİLSOY, Fariz
A considerable part of study area has boron-sodic and saline properties. In this study, in reclamation of boron soils were used water and sulphur (S). Empirical models were used in determining of leach water norm in the reclamation of soils. Analytical expressions of thesemodels are hyperbolic, force, exponential and logarithmic. At the same time, by choosing the most appropriate from these models, will use these models in large-scale leaches. Nine (2 x 2 m) parcels were used to obtain the necessary data to construct these models. Soil sampleswere taken from the parcels at depths of 0-25, 25-50, 50-75, 75-100 cm and leach water norm models were established with the obtained values. The parcels; sulphur in the amounts of control (S0 ), 4 kg (S1 ) and 8 kg (S2 ) were applied into the soil. Model selection criteria wereapplied to determine suitability of models. The following values were obtained for each application after the comparison of the eligibility criteria of the obtained models: For S0 ; Correlation Index (η) 65.3172, Root Mean Square Error (σ) 0.0547,Agreement Index (D) 0.7698 and Akaike Information Criterion (AICc)- 5.6368 with the power model, S1 ; the Logarithmic model with η: 77.8010, σ: 0.0958, D: 0.8655 and AICc: -4.5163 and S2; the Exponential model with η: 71.4723, σ: 0.0688, D: 0.8159 and AICc: -5.1790 reflected the most appropriate of the test data.
