Abstract

Abstract only available. A new form of low-pressure subsurface drip irrigation (LPSDI) system has been introduced in 2003 by the Netafim-USA company. It is a relatively low-cost system to irrigate irregular-shaped and/or relatively small fields with limited water supplies. The system is operated under low pressure (approximately 20.7 to 34.5 kPa). The pressure to operate the system is maintained using a 3-m standpipe. An experiment is currently being conducted to research soybean yield response to irrigation water and to quantify crop evapotranspiration (ET c) and crop coefficients (K c) using the LPSDI system in south central Nebraska. In addition to the results of the first year of field research, challenges, issues, and experiences associated with using LPSDI system and practical solutions to the issues will be discussed.
