Various advisory software programs to assist farm managers with irrigation scheduling have been developed or older versions modified in the last decade. The fundamental procedures for irrigation scheduling are relatively straightforward and simple, but the diversity of the programs that have recently been developed is remarkable and significant. The range of analytical options offered by these programs is increasing; some have evolved from simple irrigation scheduling programs into comprehensive and sophisticated irrigation planning and management programs. Software development and the cost to maintain weather networks for its use can be inherently very complex, and oftentimes is beyond the resources of most individual states or agencies. Some scheduling efforts manage to economize by doing things such as replacing weather station networks with satellite imagery. To enhance their power and usability, various programs make use of many ancillary databases such as the NRCS Soil Data Mart, the NRCS WEB Soil Survey, NOAA weather records, aerial images, etc. This paper provides an overview of existing and developing irrigation management programs in the U.S. and elsewhere.
