Abstract
An automated irrigation control comprising crop sensor physically attached to a crop and a light sensitive sensor having a photo-detector for monitoring light intensity of a crop, an irrigation conduit extending along the span of the irrigation zone and adapted to carry fluid, with one or more controllable valves and sensors, growth sensors placed in close proximity of the crop sensors, a computer control system, an irrigation controller, and a communications link between the computer control system, the one or more crop sensor, the three or more growth sensors, and the irrigation controller.
Claims17
A method for automated irrigation control, the method comprising;
- monitoring a received light intensity of a crop;
- converting the light intensity of a crop into electronic data;
- determining crop health conditions based on a water invariant chlorophyll index and a second vegetation index, wherein determining crop health comprises:
- calculating a first vegetation index using detected light;
- calculating the water invariant chlorophyll index from the first vegetative index using a plurality of spectral bands;
- and
- referencing the first vegetation index to the second vegetation index, wherein the second vegetation index comprises past electronic data collected, and is calculated from the same crop location;
- determining an irrigation schedule based on the crop health conditions;
- calculating a projected health value of the crop based on one or more crop conditions that include a reflection spectral image, a temperature value of the crop, and an orientation of crop leaves during high heat periods;
- adjusting the irrigation schedule based on forecasted weather data, the calculated projected health value, and a time period;
- monitoring the light intensity of the crop over the time period;
- and
- adjusting the irrigation schedule based on the projected health value crossing being between a predetermined range of threshold values.
