The effect of irrigation water quality on soil properties under center pivot irrigation systems in central Saudi Arabia
A field experiments were conducted for three growing seasons (2007 to 2009) at five different sites of soil types and salinity levels. Five different ground water qualities were used to irrigate five fields each with area of 50 to 54 hectares planted with wheat crop and the irrigation system used at each field was center pivot sprinkler system. The irrigated fields were located at different loc...
متن کاملModelling evaporation and drift losses in irrigation with medium size impact sprinklers under semi-arid conditions
A proper understanding of factors affecting evaporation and drift losses in sprinkle irrigation is important for developing water conservation strategies. For estimating drift and evaporation losses during the set sprinkler irrigation event, several outdoor single-sprinkler and block irrigation tests have been conducted. Various sprinkler±nozzle±riser height combinations were used and the varia...
متن کاملComparison of Water Distribution Characteristics for Two Kinds of Sprinklers Used for Center Pivot Irrigation Systems
Sprinkler selection influences the water distribution uniformity of center pivot irrigation systems. The sprinkling uniformity of the center pivot is crucial for the yield and quality of crops on a large scale. Rotating and fixed spray plate sprinklers (RSPSs and FSPSs) are the two most popular types. However, sprinkler selection is mainly based on price, not on differences in performance betwe...
متن کاملInvestigation of infiltration in Center Pivot irrigation system
Use of the double ring infiltrometer to measure soil water infiltration in center pivot irrigation systems isn’t an accurate approach because the real conditions of infiltration under center pivot sprinklers is different from what happens in the double ring. In this study the infiltration parameters were evaluated in real conditions of a center pivot system. For this purpose a single ring...
متن کاملCSCE 996 Independent Research Controlling Center Pivot Irrigation Systems
Excessive, wasted water has prompted the creation of the Top 10 Water Challenges of Nebraska [1]. 70% of the world’s water usage is related to agriculture [7], more efficient irrigation solutions promise a large benefit for farmers, consumers and the environment. Through a USGS grant, the Cyber-Physical Networking Lab at the University of Nebraska-Lincoln has pledged to complete an autonomous i...
