For our customers, we have developed the Varistar portal, which stores all data related to the farm. Users have constant access to a map representation of the variable applications carried out, including detailed information, to application maps, to maps of relative yield potential, to maps of soil analysis and soil conductivity* or to maps based on data from thresher yield meters*. A new feature is our Satellite Portal, which allows you to view current and historical satellite data from two satellite constellations (Sentinel 2 and Landsat 8), create composite images, and perform analyses such as Smart Scouting based on several years of history. 


The user interface of the portal is very intuitive. The portal serves as an excellent source of information and feedback for the agronomist. Based on the evolution of the measured stand condition, the agronomist can select the application strategy or identify problem zones for local field surveys. On the basis of the applications and their results, it is easy to evaluate the benefits of individual cultivation interventions and adjust their nature for future applications. All data is permanently stored in the portal, so it is easy to go back for any historical information.

Agricultural data is burdened with a high error rate. All information needs to be cleansed of such errors; it is not possible to use one algorithm that always follows the same procedure. Additional review of the outputs with an expert is needed for proper evaluation. There are a number of portals and automated systems on the market that use automated processing, but the validity of these data and their benefits tend to be very low. Our approach is that the partner for you is not a computer, but a human who takes care of your data and consults with you on the whole process of variable applications. 


Satellite portal


Our portal includes a portal of current satellite data. The satellite portal offers a plethora of ways to view and analyze hunting information. The satellite portal has two basic functionalities - one is the creation of composite images, i.e. the combination of several satellite images over a certain period of time that together create a cloud-free image, and the other is the viewing of satellite images from a specific date. Our satellite portal integrates a complete database of all Landsat 8 and Sentinel 2 imagery over the entire lifetime of the satellite constellations - so you have a view of your field going back several years.

The satellite portal offers many different vegetation indices that can be displayed in the browser, so there is no need to stick to the well-known NDVI (Normalized Difference Vegetation Index). For example, the image below shows the enhanced vegetation index (EVI), which is particularly useful to use at later vegetation stages when the NDVI no longer provides sufficient resolution of the best zones.

Another new index that can be displayed is the so-called LAI (leaf area index). It can be defined as the leaf area occurring over a certain unit of soil surface. Thus LAI = total leaf area in m2 / ground area of 1 m2. At the same time, the figure shows a different palette for displaying the data - this is particularly useful when the normal display does not provide sufficient contrast between the individual values. A larger number of palettes and settings are predefined in the portal to efficiently obtain a contrasting display for any stand.

Smart Scouting

Smart Scouting is one of the most important tools that our clients get. SmartScouting analysis evaluates current satellite data against the long-term normal and identifies risk zones in terms of vegetation development. It divides the production zones into 3 groups: below 90% of the long-term normal (problem sites), 90-110% of the long-term normal and above 110% of the long-term normal (potentially risky zones in terms of e.g. high fouling).

Smart Scouting helps the agronomist to search for places that are worth his attention and should be visited. Smart Scouting therefore does not tell you exactly what is happening at a given place, this is not possible to determine remotely. Zones that are not doing well may have been attacked by a disease or pest, there may have been more damage to the crop from wildlife, etc., zones that are doing above average may be excellent but may, on the other hand, have increased levels of weeds for example. Therefore, the role of the agronomist in evaluating the Smart Scouting evidence is irreplaceable.

However, Smart Scouting is the most important tool for optimizing variable applications. Thanks to the new Satellite Portal, it is possible to monitor the dynamics of stand development in each production zone, especially taking into account the variable applications made and their cultivation response in each zone, with updated data every five days. It is the only tool on the market that allows this and thus provides feedback for the deployment and subsequent optimisation of variable applications in the future. Analysis can also be generated for previous years and the development of individual soil blocks can be compared year-on-year.
