Evaluating Water Use and Management of Center Pivot Drag-line Drip Irrigation Systems

摘要

Center pivot irrigation is the most popular irrigation method used in Texas. Over the last 15 years, more farmers have gradually switched from furrow to center pivot irrigation. Center pivot drag line drip irrigation systems or Precision Mobile Drip Irrigation (PMDI) have gained attention in recent years because of their ability to combine the application efficiency of drip irrigation with the operational efficiency of center pivot systems. However many farmers are hesitant to implement this technology, unsure if the costs of installation and management will result in significant water and costs savings. This paper will review farmer management of such systems and attempt to quantify irrigation water use and perceived water savings from implementingthis technology concept.
