ADVANCES AND CHALLENGES WITH MICRO-IRRIGATION

摘要: As global concerns surrounding water scarcity and food security escalate, there will be more demand for micro-irrigation to meet growing demands. Micro-irrigation offers many advantages over conventional irrigation methods, including the ability apply limited amounts of directly crop root zone, incorporation fertigation, reduced weed pest infestation, lower capital operating costs. In recent decades, has been considerable growth in acreage under micro-irrigation, mainly as a result costs, improvements filtration emitter technology, increased grower confidence technology. Research advances technological have made applicable diverse set applications, cropping systems, quality conditions. Cost availability are also major drivers. nano- biofiltration techniques, soil moisture sensors, precision shows great promise advancement micro-irrigation. Nevertheless, several challenges remain, especially non-row or non-orchard crops, regions where is severely impaired. Innovations these areas required, well transfer technology small farmers water-scarce who traditionally surface irrigate. Copyright © 2013 John Wiley & Sons, Ltd.
