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 کاملEffects of salinity and irrigation water management on soil and tomato in drip irrigation
In this research, the effects of irrigation with saline and fresh water through drip irrigation method and using two irrigation management strategies: M1, M2 (M1 is irrigation with fresh water in alternative with saline water, M2 is saline water in first half time of each irrigation event and fresh water in the second half), on the yield, water productivity (WP), soil salinity, plant height...
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 کاملWireless Sensor Network Effectively Controls Center Pivot Irrigation of Sorghum
Automatic irrigation scheduling has been demonstrated using wired sensors and sensor network systems with subsurface drip and moving irrigation systems. However, there are limited studies that report on crop yield and water use efficiency resulting from the use of wireless networks to automatically schedule and control irrigations. In this 2011 study, a multinode wireless sensor network (WSN) s...
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...
