Irrigation scheduling : a review of techniques and adaption of tje USDA irrigation scheduling computer program for Swedish conditions
Erpenbeck, Joseph Matthew
Irrigation scheduling is deciding when to irrigate and how much water to apply. The objective is maximum crop production for the farmer but other benefits are possible toward better management of water resources. This report reviews soil water depletion measurement and computation approaches. Examples are given of how these irrigation scheduling methods are used in practice in the western United States. The USDA irrigation scheduling computer program is adapted for Swedish conditions. Model theory and program usage is discussed to provide the basis for establishment of an irrigation scheduling service in Sweden. The scheduling program is run for two potato fields near Ultuna to illustrate program operation. Recommendations are made toward improvement of the scheduling computer program. The development of an irrigation scheduling service in Sweden based on United States experience is also briefly discussed.
