Farklı Sodyum Adsorbsiyon Oranı Değerlerine Sahip Sulama Sularının Bazı Toprak Özelliklerine Etkisi.

Irrigating the soil with irrigation water, which has a high sodium concentration, usually increases the sodium content of the soil. The salt and the Sodium Absorption Rate (SAR) values of irrigation water cause significant changes in the physical structure of the soil. In the clayey soil, limiter variable amount of Na is specified as 1 - 1.5 meq 100-1 g soil, which corresponds to 4-8 Exchangeable Sodium Percentage (ESP) value. In this study, the effects of some parameters such as ESP, EC and pH of irrigation water with constant EC values and 0, 15, 30, 40 SAR values were investigated. During the experiment, 3 replicates were used from each subject and soil samples were taken at the end of the experiment from each layer. ESP values were found with divided into total Na to total Ca, Mg, K and Na values. EC and pH values were obtained by extracting soil samples from the laboratory and measuring them with EC and pH measuring devices. As the SAR values increased, the ESP values increased and statistically significant differences were observed between the soil layers. The highest ESP value averaged 4.124 on the third layer of SAR40, while the lowest ESP value was 1.312 on the second layer of SAR0. As the SAR values increased, EC and pH values increased, statistically significant differences between the layers were observed. [ABSTRACT FROM AUTHOR]
