Impact of agricultural water reallocation on crop yield and revenue: a case study in China
Our study area in the People's Victory Canal Irrigation District of Henan Province in China has been transferring agricultural water to the city for municipal use. This study starts with an examination of the impacts of irrigation frequency, irrigation water sources, and irrigation water supply performance on crop yield and net crop revenue, using data from a survey of 182 households in the ...

Characterization of bacterial pathogens in rural and urban irrigation water
The study aimed to compare the bacteriological quality of an urban and rural irrigation water source. Bacterial counts, characterization, identification and diversity of aerobic bacteria were determined. Escherichia coli isolated from both sites was subjected to antibiotic susceptibility testing, virulence gene (Stx1/Stx2 and eae) determination and (GTG)5 Rep-PCR fingerprinting. Low mean ...

Utilization of artificial recharged effluent for irrigation: pollutants' removal and risk assessment
The reclaimed water from soil aquifer treatment (SAT) column was reused for irrigation as the source water, pollutants' removal and health risk assessment was analyzed via the comparison with secondary and tertiary effluents. The effect of the SAT pre-treatment on the qualities and growth of different crops (Lachca sativa – lettuce, Brasica rapa var chinensis – pak choi, Cucumis sativus – ...

Microbial quality and suitability of roof-harvested rainwater in rural villages for crop irrigation and domestic use
The study aimed at assessing the microbiological quality and suitability of roof-harvested rainwater (RHRW) for crop irrigation and domestic use. In total, 80 rainwater tanks (246 samples) across three rural villages (Ga-Molepane, Jericho and Luthngele) were visited. Culture-based techniques were used to isolate bacterial microbes and identities were confirmed using matrix-assisted laser ...

Effect of irrigation with secondary treated effluent on essential oil, antioxidant activity, and phenolic compounds in oregano and rosemary
Shortage of water throughout the world dictates utilization of marginal water for irrigation. Treated urban wastewater is a common alternative water source for irrigation in arid and semiarid regions. In this study we aimed to evaluate the effect of irrigation with secondary-treated effluent on plant development, essential oil yield, antioxidant activity and selected antioxidant phenolic ...

Improving Irrigation in Browns Valley, California
In Northern California, the Browns Valley Irrigation District supplies water to hundreds of farmers. As this water source needs to supply many farmers in Northern California, accurate measurement is key as it ensures that farms are able to properly function and sustain the plants and/or livestock they have. The specific source of water that irrigates the fields in the Browns Valley District ...

Irrigating with reclaimed water through permanent subsurface drip irrigation systems
ABSTRACT In Hawaii, reclaimed water has been used in agricultural irrigation and the irrigation of golf courses and other large landscaped areas. However, the Hawaii Department of Health's new "Guidelines for the Treatment and Use of Reclaimed Water" published in November 1993, limits uses of reclaimed water through overhead sprinkler irrigation systems. The subsurface drip irrigation concept ...

Remote monitoring helps growers, water districts do their jobs
Propeller flow meters have long been an important tool for agricultural irrigation management. As water scarcity and resource management have become increasingly critical, getting the most timely, accurate readings available from those meters is becoming more important than ever. Here is how growers and water conservation districts (WCDs) are each getting the best of both worlds for their own ...

Water reuse through subsurface drip irrigation systems
Water reuse in Hawaii has been primarily relegated to agricultural irrigation and irrigation of golf courses and other large landscaped areas. The continuing effort to conserve and preserve potable water resources emphasizes using alternative water sources for irrigation. Agriculture, golf courses, highways, parks, playgrounds and cemeteries are among the heaviest users of irrigation water due to ...
