Interpretive Summary: Subsurface drip irrigation (SDI) has been used to irrigate a variety of crops in the United States. SDI can achieve high crop water use efficiency if proper design, operation, and maintenance procedures are followed. More farmers are using SDI because of recent improvements in its various components, as well as new knowledge on how to design and manage SDI systems. However, several barriers have prevented the more widespread adoption of SDI. The main barrier is the initial cost. Besides cost, many farmers feel that SDI is difficult to manage, and they feel that there is not enough education and technical support available. Many SDI systems have been damaged by rodents chewing on laterals, and this remains a serious problem in some areas. Continued research and education on SDI can overcome these problems. This will require cooperation between the irrigation industry, federal, state, and local agencies, and universities.

Technical Abstract: Subsurface drip irrigation (SDI) although a much smaller fraction of the microirrigated land area than surface drip irrigation, is growing at a much faster rate, and is the subject of considerable research and educational efforts in the United States. This paper will discuss the growth in SDI, highlight some of the research and extension efforts, and point out some of the challenges to SDI adoption and some of the future opportunities for SDI.
