HighlightsSubsurface drip irrigation (SDI) has continued to expand in irrigation area within the U.S. during the last 15 years.Research with SDI continues for multiple crop types (fiber, grain and oilseed, horticultural, forage, and turf).SDI usage on many crops has matured through research and development of appropriate strategies and technologiesDespite some persistent challenges to successful use of SDI, important opportunities exist for further adoption.Abstract. Subsurface drip irrigation (SDI) offers several advantages over alternative irrigation systems when it is designed and installed correctly and when best management practices are adopted. These advantages include the ability to apply water and nutrients directly and efficiently within the crop root zone. Disadvantages of SDI in commercial agriculture relative to alternative irrigation systems include greater capital cost per unit land area (except for small land parcels), unfamiliar management and maintenance protocols that can exacerbate the potential for emitter clogging, the visibility of system attributes (components and design characteristics) and performance, and the susceptibility to damage (i.e., rodents and tillage) of the subsurface driplines. Despite these disadvantages, SDI continues to be adopted in commercial agriculture in the U.S., and research efforts to evaluate and develop SDI systems continue as well. This article summarizes recent progress in research (2010 to 2020) and the status of commercial adoption of SDI, along with a discussion of current challenges and future opportunities. Keywords: Drip Irrigation, Irrigation, Irrigation systems, Microirrigation, SDI, Water management.

“…With soil moisture content during the first half of the 2017 growing season, the potential for deeper root development into the soil profile after three consecutive growing seasons of DRZ application is also a consideration. Periodic digital imaging of root growth in both field and greenhouse studies is currently being analyzed and may contribute to a better understanding of the root growth dynamics influenced by DRZ application (Zuniga et al, 2017(Zuniga et al, , 2018. These data will be presented for publication following the completion of observations during the 2018 growing season.…”

In 2015, a project was launched to evaluate the potential for using a new form of sub‐surface drip irrigation. Rather than applying micro‐irrigation through horizontal buried lines, drip irrigation was delivered into vertical tubes placed 1 to 4 ft into the root‐zone soil. Juice and wine grapes were selected as the model plant systems for these proof‐of‐concept trials.
