The program uses information generated by any soil moisture and crop stress measurement devices including tensiometers, gypsum blocks, neutron probes, infra red guns and manual soil probes.

The area monitored by the program is divided into fields. Each field is a unit with a single crop that is irrigated by the same irrigation system. The field record determines the number of layers monitored at the field and the depth of each layer. In each field, there are several measurement stations. Each station monitors all the field layers. The soil types may differ from one layer to the other in a single station and may differ on the same layer from one station to the other. Soil moisture readings, crop stress readings and irrigation events are recorded as they occur during the irrigation season. Numeric and graphic analysis of the soil moisture status are generated as the irrigation season progresses.

The program was designed in a modular fashion to allow the user to pick and choose only the configuration he needs at the current time and to expand the system as his monitoring network develops.

Two versions of the program are available the Ag Version and the Non Ag Version.

The basic program can handle up to 30 measurement stations.

The extra modules that can be added to the program include:

1. 30 Station Expansion Modules: Each such module adds 30 stations and fields to the data base of the program.
2. Consultant Module: This module allows the consultant to define growers to which the fields belong and prepare reports by ranch.
3. Device Interface Modules: Each module makes it possible to read directly soil moisture and crop stress readings directly from text files created by the data loggers of the measurement devices.
