Questions & Answers

Quickly and clearly summarized

 

 

What do the colors of my fields stand for?

They provide a quick overview of the usable field capacity of your fields:

Field is too wet

If your field is colored dark blue, the usable field capacity is 95% - 110%

Optimally irrigated

Light blue fields have a usable field capacity of 80% - 95%

Sufficiently irrigated

The green color represents a usable field capacity of 60% - 80% 

Irrigation needed shortly

Yellow fields have a usable field capacity of 40% - 60%

Irrigation needed

The orange color represents a usable field capacity of 20% - 40%

Irrigation overdue

If your field is colored red, the usable field capacity is 0% - 20%

In which countries is WaterFox available?

Fields can be created all over the world. Our analyses are currently only activated for the European region.

Can I consider sub-crop specific management in WaterFox?

Yes, you can divide fields as often as you like in WaterFox and create plots or sets, beddings and irrigation areas of overhead sprinkler or hose wheel cart.

Can I also document cultures under foil or fleece in WaterFox?

It is possible to mark which fields are covered with foil or fleece in WaterFox. For these lofts, the soil moisture calculations are disabled to maintain clarity.

Does WaterFox offer a weather forecast?

You will not find classic and complete weather forecasts in WaterFox. This is already done by other products. WaterFox considers local seven-day rain forecasts from other providers and shows them. In addition, the expected development of the soil moisture is forecast seven days in advance, with day accuracy, according to the Geisenheim model.

Can I connect my weather station in WaterFox?

Yes, you can either manually enter the data of your own weather station into WaterFox or connect it automatically via a data interface. Just contact the customer support for this purpose.

How do I get access to data from public weather stations?

To do this, enter your company address in the settings under farm address. You will then get access to public weather stations in your area.

Questions about the technology behind it

What does the usable field capacity (ufc) mean?

How well the plant can access the soil water is essential for plant growth. The measure of the availability of water is the usable field capacity (nFK). It describes the amount of water that the roots can extract from the soil with their suction power.

The higher the ufc, the more water is available - as capacity - in the soil for the specific plant. Different plants can extract different amounts of water from the same soil, so they also have different ufc. If the ufc is above 100%, the soil is overwatered.

In addition, the amount of field capacity depends on the grain size distribution of the soil, the soil structure and its content of post-mortem soil organic matter (humus). The water in the fine pores of a soil cannot be absorbed by plant roots. If only this water is still present, the ufc drops to 0%, because the plant cannot take up any water, even though there is still water in the soil.

What do the parameters soil points and soil type mean? How are they related to soil moisture?

The soil type describes the composition of the field soil on which a crop is grown. The grain size distribution of the soil is considered, which results from various processes, such as weathering or other soil formation processes. A distinction is made between the grain sizes sand (S), loam (L), silt (Si) and clay (C). Due to the different grain size distribution, the respective soil types can hold different amounts of water. Therefore, soil type has a significant influence on soil moisture.

Soil points describe the quality of an agricultural area. The initial point is a standard value, which is modeled by various factors, such as climate, slope, and forest shade. Basically, a low value represents poor soil and a high value represents good soil.

There is no causal relation between soil type and soil points. They are two separate parameters that can be saved in WaterFox. To achieve a realistic representation of your farm in the software, simply enter these values to the corresponding fields.

Why does the usable field capacity decrease when I change from sandy soil to loamy soil?

Sand soil can hold more water than clay soil. However, due to the grain size of sand, the plant can extract less water from the soil. Therefore, if you change the soil type in WaterFox from sand to clay, the analysis result will change.

How is soil moisture calculated with the Geisenheim model?
The Geisenheim model, also called "climatic water balance", is defined as the difference between the measured rainfall and the simultaneously climatically possible evapotranspiration.
Since the climatically possible evapotranspiration only represents the actual water consumption of a plant stand inadequately accurately, a correction factor is required for adjustment. This factor depends on the plant species and the growth stage of the plant.
The desired result is the potential water demand of the crop species, which is determined by the evaporative demand of the atmosphere and the crop species-specific stage of development.
If you use the Geisenheim model in WaterFox, your irrigation amount will be calculated depending on soil property, crop type, development stage and potential evaporation.
How do we get to the automated irrigation recommendations?

The heliopas.ai irrigation model and the resulting automatic irrigation recommendations have their origin in the so-called Geisenheim irrigation control. With the help of the Geisenheim model, predictions can be made about the potential water need of the respective crop type (in the next 7 days).

WaterFox requires the following four specifications in order to generate automated recommendations for the irrigation of the fields or sets: 

    1. Crop type
    2. Seeding date
    3. soil type
    4. Weather data: Rainfall and evapotranspiration

In the automated irrigation recommendation, all these factors, as well as the predicted precipitation and water buffers, are taken into account and included in the planning. A proposal is created with the goal of ensuring that the soil does not exceed or fall below the deficit limit. All necessary tables and data, as well as the calculations are integrated in WaterFox and run in the background. As a result, you get an irrigation proposal that is customized to the individual situation of your field.

What is the difference between satellite data and the Geisenheim model?
You can choose in WaterFox to receive irrigation recommendations based on analyses of satellite data. Then the current soil moisture is calculated based on specially developed analyses of satellite images. Future forecasts are not currently available, but are planned.
We recommend to select the Geisenheim model in the settings. Here, crop-specific properties are also included in the calculation. In practice, these recommendations have proven to be more reliable, especially for dense vegetation. With the Geisenheim model, you receive the irrigation deficit exactly to the day in millimeters of deficit quantity and also receive a forecast for the next seven days.
Are the satellite images live?

By now we have connected a large number of satellite data sources, so that we receive a new measurement within 24 at least. These are analyzed by our artificial intelligence and immediately integrated into the calculation of the soil moisture of your fields. The satellite image analyses are therefore up-to-date on a daily basis, but not live.

Do the soil moisture analyses also consider differences in soil moisture within the field?

WaterFox calculates soil moisture with a spatial accuracy of 10×10 meters. This is unique in the world and for the first time enables a soil moisture analysis that also takes into account differences in soil moisture within the field. Thus, sub-crop-specific irrigation becomes possible.

Is it possible to insert my irrigation documentation, previously kept in Excel spreadsheets, retroactively into WaterFox?

Yes, just send your file as an email attachment to kundenhilfe@waterfox.com

How can I import data from other systems into WaterFox?

Simply send your punch list as an e-mail attachment to kundenhilfe@waterfox.com

Administration

What are the costs?

The fee for WaterFox is composed of a basic amount of 250 € per year for a farm and a variable price depending on the type of irrigation and the number of hectares.

Depending on the irrigation type, the variable costs are as follows:

  • Drip irrigation: 2 € / ha / year
  • Mobile irrigation: 2 € / ha / year
  • Circular and linear irrigation: 6 € / ha / year

Do I have to buy a WaterFox license for every user in my company?

No, you pay nothing extra for additional employees. You can even include contractors and agricultural consultants for free. You can adjust the level of rights and access yourself. With WaterFox you pay only once for your entire farm, depending on the tariff and hectare size. After that, you can add as many employees and externals to your farm as you like.

Can I limit the access rights of employees or externals in WaterFox, and if so, how?

Yes, you can assign permissions within WaterFox completely individually. To do this, open our WaterFox browser application. On the "Settings" tab, you will find the User Management button. Here you can add new users, remove users and manage the permissions of each user.

We recommend assigning the rights depending on the activity. Here is an example distribution of access rights:

The administrator is given the following permissions:

  • Be able to create, edit and delete a field
  • Be able to add, edit and delete your own weather stations
  • Add and remove new users from the company and manage their permissions.

  • Be able to plan irrigation measures
  • Be allowed to request irrigation measure
  • Be allowed to block a field/set for other measures
  • May view the irrigation diary
  • Can delegate the execution of measures
  • May start and stop irrigation operations
  • Set fields and employees active or passive
  • Can adjust warnings individually

    The kappo or irrigation coordinator would have the following permissions:

    • Enter and edit the irrigation tasks
    • Enter and edit rainfall
    • May view the irrigation diary
    • Can delegate the execution of measures
    • May start and stop irrigation operations
