A Web-Based Advisory Service for Optimum Irrigation Management

Implementing the dual crop coefficient approach in interactive software. 1. Background and computational strategy

“…However, none of the examples describes the use of an irrigation scheduling water balance model adopting the dual K c approach. The Irrigation Management-Online software of Abourached et al (2007) and Hillyer and Sayde (2010) is one of only a few irrigation scheduling programs that employs the dual K c method. Most of the examples given do illustrate the robustness of the dual approach and the diversity and relative complexity of related applications.…”

Application of a New Web-Based Tool(CropWaterUse) for Determining Evapotranspiration and Irrigation Requirements of Major Crops at Three Locations in Queensland

“…Tools can be developed that use weather data to assist growers make both strategy and tactical decisions based on daily weather data. There is a long history of development of computer programs that use weather data to aid in irrigation scheduling, some recent and some dating back to the time when personal computers first became available (Abourached et al, 2007;Brown et al, 2010;Car et al, 2008;Chapman et al, 2008;Chauhan et al, 2011;Chopart et al, 2007;Cull, 1979;Davidson et al, 1998;Evett and Lascano, 1993;Fox et al, 1993;Howell et al, 1995;Inman-Bamber and Attard, 2005;Jensen, 1969;Kincaid and Heermann, 1974;McKay et al, 2009;Raes et al, 2009;Richards et al, 2008;Steduto et al, 2009;Thysen and Detlefsen, 2006). Unfortunately, however, historically growers have been slow to adopt these tools for practical decision-making.…”
