Minimum Overnight Temperature

Estimates minimum overnight temperature using Brunt Equation, and sunset air and dew point temperatures.

Irrigation Risk (Evaporative Cooling Potential)

Evaporative cooling may result in plant damage when water is used for cold protection during dry windy conditions. Below is a table that categorizes evaporative cooling potential as "irrigation risk".

View irrigation risk criteria.

Station Current Irrigation Risk Current Air Temp ° F Current Wet Bulb Temp ° F Current Max Wind Speed mph
Forecast Irrigation Risk
Irrigation Risk Time Air Temp ° F Wet Bulb Temp ° F Wind Speed mph

*Note: 'None' for Irrigation Risk indicates that Tair was at least 10 degrees F above your critical temperature, or at least 6 degrees above Twetbulb with little wind. In either case you should always use your best judgement to determine whether to irrigate.

Irrigation Cutoff Temperature

Once the cutoff temperature has been reached, it is not necessary to continue irrigation until all ice has melted from the plant.

Crop Water Use and Irrigation Scheduling Guide for North Florida

Show/Hide Directions

  1. Select the crop of interest below
  2. Use the table to determine the Average Daily Water Use of your crop.

    -Find the current month along the left side of the table.

    -Determine the point of interest in the growing season across the top of the table.*

    -The intersection of month (vertical column) and plant growth stage (horizontal row) shows the average daily water use for your crop.

  3. Select an Irrigation Interval and Application Amount table based on your soil water holding capacity (either 0.7 or 1.0 inches per foot).

    -Find your crop’s estimated rooting depth along the left side of the table.

    -Find your crop’s average daily water usage (from the previous table) along the top.

    -The intersection of rooting depth and average water usage shows the irrigation interval and application amount for your crop.**

    4. *Week after planting is the least accurate method for estimating plant growth stage due to the effects of planting date and weather, so should be used with caution.
    **Suggested irrigation schedules apply for the following conditions:
    -Overhead irrigation systems with an application efficiency of 75%.
    -Soil water holding capacity of 0.7 or 1.0 inches per foot.
    -Available soil moisture depletion of 50%.
