F.A.Q.
  • How does AQUATEK estimate the water use of my field?
    The AQUATEK model combines regular satellite images of the crop canopy with data from a network of local weather stations and information on soil type, actual rainfall and irrigation, producing updated maps of daily crop water use in 6-metre squares across your fields. This provides you with an additional tool for applying the right amount of water, when and where your crops need it.
  • When does AQUATEK give me an alert?

    AQUATEK will provide you with an alert when:
    1: It detects that a field is close to being under water stress;
    2: A substantial change has been detected in the health of a crop; or
    3: Irrigation and rainfall records have not been updated for an extended period.
    You will also be alerted to the arrival of the first satellite image for a new field and to the dates your AQUATEK service starts and ends.

  • Can I still access AQUATEK if I decide not to pay for the service?
    Yes. Even if you decide not to pay for the service, after trial period expiration, you will still be able to access the AQUATEK platform. However, you will be unable to receive our service such as field-specific data intended to help with your crop management.
  • Is my subscription automatically renewed?
    No. As the cost of AQUATEK depends upon the area of cropping you use it for, each year you will be able to select the fields you wish to be included in the service for that specific year and then confirm payment for the number of hectares they cover.
  • What happens at the end of the trial period?
    Towards the end of the AQUATEK trial period you will receive reminders that your trial period is coming to an end and in order to continue using the service, you will have to pay for further use. Selecting the fields for which you would like to keep using AQUATEK and filling in your payment details is easy and straightforward. If you decide not to continue using the service, you don't have to do anything. You will simply stop receiving new water use and crop health information.
  • When will AQUATEK be offered for crops other than corn?
    We are constantly working to upgrade both the scope and functionality of AQUATEK, including extending the service to other crops. We will keep you informed of all AQUATEK developments through the service and other suitable communication channels.
  • How often will I receive a new satellite image and field health data for my crop?
    You will receive new AQUATEK satellite images and health updates on regular basis through the growing season - subject, of course, to weather conditions and crop stage
  • How often is the irrigation advice updated?
    Typically your AQUATEK irrigation advice is updated every day.
  • How should I interpret the irrigation forecast?

    Your AQUATEK irrigation advice is provided daily from the latest information and forecasting available to us. In the Irrigation Forecast dashboard for each field you will find:
    1) Water Stress Period: The estimated number of days before the soil water is forecast to reach the level at which we expect your crop to starts experiencing water stress.
    2) Crop Water Consumption: Estimated total water consumption of your crop in millimeters forecast over the next seven days.
    3) Maximum Water Limit: The total water application in millimeters AQUATEK suggests you do not exceed over the next seven days to optimize water and energy use.

  • What does Field Crop Water Use mean ?
    Field Crop Water Use is the assessed amount of water in millimeters used by the crop. AQUATEK calculates this for every 6-metre square to provide an estimation of average water use for each of your fields.
  • What does the Water Dashboard show?
    Updated daily to show the estimated value for the previous day, the Water dashboard displays the projected soil moisture status of every one of your fields as a percentage number:
    1: At 100% your soil is estimated to be at field capacity;
    2: At 0% our estimation is that the Minimum Allowable Depletion level has been reached and your crop should start experiencing water stress;
    3: At -100% your field should have reached Permanent Wilting Point.
    The Water dashboard needs to be kept above 0% for reaching maximum field performance.
  • What does the Health Dashboard show?
    Based on the latest available satellite data, the Health dashboard provides an immediate summary of estimated crop health across each of your fields.
    Overall health projection is displayed as the percentage of the field coded green, representing the proportion of your field which should be able to achieve the projected maximum yield potential for a particular field.
    Green areas of the field health map indicate where our system evaluated your crop as growing better than grey/black areas which may be under stress from pests, disease or other factors and should be prioritised for investigation.
  • Over what period can I expect to receive maps, irrigation suggestions and crop water use data?
    You will typically receive your first AQUATEK image from soon after crop emergence through to harvesting, although not before April 1st and after October 31st.
    In Andalucía in southern Spain the service is available from March 15th until October 15th.
  • What does the Soil Deficit Graph show?
    This AQUATEK graph shows the estimated soil moisture level of your field from its planting date typically on a daily basis, using data from more than 275 'virtual' probes per hectare and information on irrigation, rainfall, local weather conditions and soil type.
    It comprises three main lines: (1) Soil Water Depletion; (2) Minimum Allowed Depletion; and, (3) Wilting Point.
    For the projected efficient production, our suggestion is that you should schedule your irrigation to keep the soil moisture level between Field Capacity and Minimum Allowed Depletion line.
  • How should I interpret the Water Use Map?
    The water use map gives you a colour-coded projection of your crop's use of water across the field based on AQUATEK's 6-metre square resolution, allowing you to plan your irrigation more precisely.
    More water in white and yellow areas is assessed being consumed and less water in red areas which depending on the stage of crop development, suggests they may be growing slower than the yellow areas through estimated lack of water.
  • How should I interpret the Crop Health Map?
    Precision satellite monitoring also allows AQUATEK to map areas of particular crop stress within your fields so we can help you in taking early action to tackle performance-limiting conditions. Green areas of a particular field health map indicate where your crop is estimated to grow better than grey/black areas for that particular field which may be under stress from pests, disease or other factors and should be prioritised for your investigation.
  • How often I need to enter irrigation and rainfall data?
    You need to enter any water supply data as soon as the irrigation is carried out or rainfall occurs. This will ensure your AQUATEK monitoring is up-to-date and accurate . This way we will be able to support you in your cost-effective irrigation management.
  • How can I take into consideration my irrigation equipment efficiency?
    AQUATEK monitors your crops' actual and forecast water consumption to alert you to the projected amount of extra water they will need over the coming week. The amount we suggest you to apply is easy to calculate from the efficiency of your irrigation equipment. For example:
    >> DRIP IRRIGATION with 95% Efficiency
         AQUATEK Water Use Consumption (next 7 days) = 45 mm
        Approximate Irrigation Required (45 x 100/95) = 47.4 mm
    >> DRUM/SPRINKLERS with 70% Efficiency
        AQUATEK Water Use Consumption (next 7 days) = 45 mm
        Approximate Irrigation Required (45 x 100/70 ) = 64 mm
  • I am using flood irrigation: How does AQUATEK help me make my irrigation decisions?
    AQUATEK can support you in making a decision on when, where and by how much to irrigate. The system's water use maps and soil deficit graphs provide you with an additional tool to track your crops' water consumption through the growing season. It also gives you a daily forecast of the number of days before each field is projected to enter water stress if it receives no rainfall or irrigation
  • I am using pivot or ranger irrigation: How does AQUATEK help me make my irrigation decisions?
    AQUATEK can support you decide in making a decision on when, where and by how much to irrigate. The system's water use maps and soil deficit graphs provide you with an additional tool to track your crops' water consumption through the growing season. It also gives you a daily forecast of the number of days before each corn field is estimated to enter water stress if it receives no rainfall or irrigation, together with the amount of extra water we assess the crop will require over the next 7 days to avoid this.
