Monitoring the Delta T value, helps you determine whether conditions are suitable for spraying, fertilizers, or other treatments.

  1. To use Delta T on your farm, you will need a sensor or weather station to measure the dry bulb temperature, wet bulb temperature, and relative air humidity. Once you have that in place, connect them to Farmable.

    We will automatically calculate Delta T by subtracting the wet bulb temperature from the dry bulb temperature, measured by your station.

  2. Next, you will need to determine the optimal range for Delta T for the crop treatments you plan to apply. This information can typically be found in the product instructions or by consulting with your agronomist.

  3. Check the current Delta T value right before starting your job. Delta T can be found inside your weather station or on the screen where you start your job. Determine whether conditions are suitable for spraying.

    When the Delta T value falls within the optimal range between 2 and 8, you can plan to apply your crop treatments. If the Delta T value is outside of the optimal range, either below 2 or above 8, you may want to wait for conditions to improve.

It's important to note that Delta T is just one of several factors that influences the performance of sprays and other crop treatments. You should therefore also consider other factors including wind speed, humidity, temperature, and the type of treatment being applied. Also, check with your agronomist in case of doubt.
