METHOD AND SYSTEM FOR AUTOMATED DIFFERENTIAL IRRIGATION

摘要

The present invention discloses an automated method for optimizing irrigation, whereby different parts of a field are irrigated different amounts, based at least in part on an analysis of spatial soil properties of the field, and extrapolation of data from soil sensors placed in the different parts of a field.

主权项

1. A computerized differential irrigation system comprising:
a computerized Topography Integrated Ground watEr Retention (TIGER) map generator receiving at least the following inputs:
an input describing topographical features of an area to be irrigated; andan input describing physical soil properties of the area to be irrigated, and in which the computerized Topography Integrated Ground watEr Retention (TIGER) map generator includes:
a computerized topographic feature processing functionality providing information relating to at least one of slope, aspect and catchment area features of said area to be irrigated; anda computerized topographic feature utilization functionality employing at least one of slope, aspect and catchment area features of the area to be irrigated for automatically ascertaining water retention at a plurality of different regions within the area to be irrigated; and a computerized computing functionality employing the Topography Integrated Ground watEr Retention (TIGER) map together with at least current outputs of wetness sensors located at the plurality of different regions within the area to be irrigated to generate a current irrigation plan; and a computerized irrigation control subsystem automatically utilizing the current irrigation map to control irrigation within the area to be irrigated based on the current irrigation instructions and to cause different amounts of water to be provided to the different regions within the area to be irrigated.
