1. 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.
