Quickly and clearly summarized.

 

 

What do the colors of my strokes mean?

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%

Optimal irrigation

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

Sufficient irrigation

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

Irrigation soon necessary

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

Irrigation necessary

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

In which countries is RiverFox available?

You can create fields worldwide. Our Analyses are currently only available for the European region.

Can I take site-specific management into account in RiverFox?

Yes, in RiverFox you can divide sections as often as you like and create sets, beds and irrigation areas for flying pipes or large-scale pivots.

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

In RiverFox, you can mark which fields are covered with foil or fleece. The soil moisture calculations are then deactivated for these fields in order to maintain clarity.

Does RiverFox offer a weather forecast?

RiverFox does not offer classic, complete weather forecasts. Other products already do that. RiverFox takes into account local seven-day rain forecasts from other providers and displays them. In addition, the expected development of soil moisture is forecast seven days in advance to the exact day according to the Geisenheim model.

Can I connect my weather station to RiverFox?

Yes, you can either enter the data from your own weather station into RiverFox manually or connect it automatically via a data interface. Simply contact customer support.

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

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

Questions about the underlying technology

What does the usable field capacity (nFK) mean?

The decisive factor for growth is how well the plant can access the soil water. The measure for the availability of water is the usable field capacity (nFK). It describes the proportion of water that the roots can extract from the soil with their suction forces.

The higher the nFK value, 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 nFK. If the nFK exceeds 100%, the soil is overwatered.

The level of field capacity also 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 the plant roots. If only this water is left, the nFK falls to 0%, as the plant cannot extract any water, even though there is still water in the soil

What do the parameters soil points and soil type mean? How do they relate 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 is created by various processes such as weathering or other soil formation processes. A distinction is made between the grain sizes sand (S), loam (L), silt (U) and clay (T). Due to the different grain size distribution, the respective soil types can hold different amounts of water. The soil type therefore has a significant influence on soil moisture.

Ground points describe the quality of an arable area. The starting point is a standard value, which is modeled by various factors such as climate, slope inclination and forest shade. In principle, a low value stands for poor soil and a high value for good soil.

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

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

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

How is soil moisture calculated with the Geisenheim model?
The Geisenheim model, also known as the "climatic water balance", is defined as the difference between measured precipitation and the simultaneous climatically possible evaporation.
As the climatically possible evaporation does not accurately represent the actual water consumption of a plant population, 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 requirement of the respective crop, which is determined by the evaporation demand of the atmosphere and the crop-specific stage of development.
If you use the Geisenheim model in RiverFox, your irrigation quantity is calculated depending on soil properties, crop type, stage of development and potential evaporation.
How do we arrive at the automated watering recommendations?

The heliopas.ai irrigation model and the automatic irrigation recommendations generated from it have their origins in the so-called Geisenheim irrigation control system. With the help of the Geisenheim model, predictions can be made about the potential water requirements of the respective crop type (over the next 7 days).

In order for RiverFox to generate automated recommendations for the irrigation of the fields or sets, the following four details are required: 

    1. Culture type
    2. Sowing date
    3. Soil type
    4. Weather data: Precipitation and evaporation

The automated irrigation recommendation takes all these factors, as well as the predicted precipitation and water buffer, into account and includes them in the planning. The result is a proposal with the aim of ensuring that the soil does not exceed or fall below the deficit limit. All the necessary tables, data and calculations are integrated in RiverFox and run in the background. The result is an irrigation proposal that is tailored to the individual situation of your field.

What is the difference between satellite data and the Geisenheim model?
You can set RiverFox to provide you with irrigation recommendations based on analyses of satellite data. The current soil moisture is then calculated using specially developed analyses of satellite images. Future forecasts are not currently available, but are planned.
We recommend selecting 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 with dense vegetation. With the Geisenheim model, you receive the irrigation deficit to the day in millimeters of deficit and also receive a forecast for the next seven days.
Are the satellite images live?

We have now connected a large number of satellite data sources so that we receive at least one new measurement within 24 hours. These are analyzed by our artificial intelligence and immediately included in the calculation of the soil moisture of your fields. The satellite image analyses are therefore updated daily, but are not live.

Do the soil moisture analyses also take into account differences in soil moisture within the field?

RiverFox 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 the differences in soil moisture within the field. Partial field-specific irrigation is therefore possible.

Is it possible to retroactively add my irrigation documentation, which was previously kept in Excel spreadsheets, to RiverFox?

Yes, simply send your file as an e-mail attachment to kundenhilfe@heliopas.com

How can I import data from other systems into RiverFox?

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

We will import your strikes as soon as possible and inform you about them afterwards.
