Title

THE STUDY OF IRRIGATION ON SOIL SALINITY (CASE STUDY: YAZD-ARDAKAN PLAIN)

Pages

  197-210

Abstract

 Salinity has affected about 10% of world lands and damages due to SALINITY are recorded as 3 ha per minutes. Due to geographic and climate conditions which is arid and semi arid, Iran is 5th among Asian countries. The central part of Iran and specially Yazd province is one of the major centers of SALINITY and dust damage and desertification. SALINITY which is caused by human activities, especially agriculture & IRRIGATION activities (secondary SALINITY) is differ from normal SALINITY and is the most important factor for desert developing in arid and semi arid lands.An area in north of Ardakan was studied to find the IRRIGATION effect on Yazd-Ardakan desert SALINITY. At first, we collected the information about area, such as geology, topography, climate, water sources and agriculture. Then 8 study areas in three types (barren, agricultural and garden land) were sampled in 0-30 / 30-60 / 60-90 cm.We repeated for 3 times to collect more precious results and sent samples to laboratory. Results show that IRRIGATION with salty water in area has caused SALINITY. But in general, the comparison between rate of electrical conductivity of saturation extract (ECe) in barren, garden and agricultural lands showed that IRRIGATION decrease SALINITY in that area and its EC is very low. On the other hand the rate of EC in depth is more. This matter shows the effect of leaching and drainage factors by IRRIGATION on depth which lead to decrease SALINITY and so in that area which the elementary SALINITY is high, IRRIGATION can have a good effect on SALINITY.
