The salt movement on soil profile at sprinkler and drip irrigation method applications

Abstract

In this study, the effects of sprinkler and drip irrigation methods on salt distributions within soil profile were researched. The irrigation interval for each irrigation methods was 7 (seven) days and water content of soil was replenished to the field capacity in each irrigation (FC). The irrigation content of soil was measured by Δt Profile Probe moisture meter.

As a result, when initial and final soil salinity values soil depth compared, it was observed that the soil salinity decreased 40.8% on sprinkler irrigation and 29.5% on drip irrigation method at depth of  0 -30 cm, 26.3% on sprinkler irrigation method and 25.5% on drip irrigation method at depth of 30 – 60 cm whereas the soil salinity increased 58.8% on sprinkler irrigation method and 56.2% on drip irrigation method at depth of 60 -90 cm, 54.6% on sprinkler irrigation method and 31.8% on drip irrigation method at depth of  90 -120 cm.
