Abstract.

System longevity of systems is an important economic factor to minimize amortized investment costs for subsurface drip irrigation (SDI) systems, especially when growing lower valued commodity crops. Kansas State University established a research site to study SDI in 1989 and one research study area was used for continuous production of SDI corn for 27 seasons without replacement. This paper discusses the long term performance of this system and the implications of its longevity. The system was abandoned at the end of the 2015 crop growing season due to leaks arising from breakdown in the plastic material.
