Evaluation and Determination of the Best Irrigation Methods Suitable for the Agricultural Lands of Abu Gharq in Babylon

Abstract

Abstract The aim of this research is to compare the suitability of land for surface irrigation sprinkle and drip irrigation methods according to a parametric evaluation system. The current study was carried out on the soils in the city of Abu Gharq Babylon Governorate south central area of Iraq. with an area of 25026.38 ha, the studied area lie between latitude 44 E, longitude 32 N, After analyzing and evaluating soil properties, Its coordinates were determined by a global positioning device (GPS). The samples were saved and brought to the laboratory to conduct the necessary laboratory measurements on them. The results showed that the silt and clay separations prevailed compared to sand. -400.59 gm kg−1. Also, a high calcium carbonate mineral, CaCo3, was observed, ranging between 16.82-27.00%. As for salinity, it was high in the area, ranging from 3.14-10.78 dm−1. Also, showed decrease in the ratio of organic matter ranged between(10.32-0.97) %. Conclusion as it was found that drip irrigation is more effective and efficient than the two methods of surface irrigation and sprinkler. Recommend irrigation management the drip irrigation system as the best method to be applied to the study area, the main factors determining the use of drip irrigation are the texture and slope, while sprinkler irrigation was the factor of soil texture and salinity. For drip irrigation methods, the main determining factor was calcium carbonate in the soil.
