Kurz und knapp - Du hast Fragen, wir haben die Antworten.
The application volume is calculated using specially developed algorithms. When applied in single-point mode (e.g. organic or mineral nitrogen fertilization or growth regulator application), the desired application amount is specified by the farmer and then, depending on current plant development, optimally distributed by the ISARIA system.
However, some crops also have so-called ISARIA expert systems. Here, the ISARIA system completely independently calculates the optimal application amount for the current plant population and the current yield potential based on integrated, plant-growing know-how. As a result, plant populations are always supplied with exactly the optimal amount of application and losses are minimized.
The calculated output quantity is passed on to the attachment immediately during the crossing. It is also possible to use the online portal ISARIA CONNECT to calculate application maps based on sensor measurements carried out. These application cards can then be processed at a later stage.
In addition to plant sensors, the ISARIA system also offers the free data management application ISARIA CONNECT on. Here, the individual shots can be managed and measurement data from the sensors can be read in and stored, compared and analyzed. ISARIA CONNECT visualizes the measurement data in an easy-to-understand way and also offers access to satellite maps as well as temperature and precipitation data. In ISARIA CONNECT, application maps can be created and the measurement data can be used for crop management. The data management application also offers the option of transmitting measurement data in various file formats to other data portals.
With ISARIA PRO Active and ISARIA PRO Compact, ISARIA offers farmers two reliable sensors for site-specific management. The two sensors differ in their measurement technology. The ISARIA PRO Active is an active plant sensor because it actively irradiates the plant population with its own light source. The ISARIA PRO Compact, on the other hand, uses sunlight as a light source and does not have its own light source. This is why we speak of a passive measurement principle. A passive plant sensor depends on a reference (irradiation sensor on the roof of the tractor), which is used to measure the intensity of solar radiation. This allows the reflection of the plant population to be measured regardless of irradiation conditions (e.g. cloudiness).
Both plant sensors measure the red and near-infrared light reflected by the plants in the same way while crossing the plant.
This reflection correlates very strongly with biomass and the N supply of plants. Based on these values, the optimal application quantity is then calculated in accordance with the chosen strategy and transmitted directly to the attachment.
In principle, ISARIA plant sensors allow you to measure either the nitrogen supply status of the plants or the biomass growth of the stock.
Depending on the state of development and the application carried out, the appropriate index can be selected. In early development phases and smaller plant populations, very good results can be achieved with the biomass measurement value. In later development phases and when stocks are dense, biomass-based measurement values can no longer differentiate the stocks from one another. Here, the N supply then provides reliable measurement values.
With ISARIA plant sensors, application agents are applied where they are actually needed. Compared to uniform distribution, the amount of fertiliser available is optimally distributed, application agents are applied as needed and oversupply and undersupply can thus be minimized. Expensive seeds can also be saved when reseeding grassland with the help of plant sensors. With regard to yield increases, practical results have shown that yield can be maximized through site-specific management using plant sensors.

ISARIA plant sensors can generally be used for all crops. The sensors measure the N supply and biomass growth of the plants. Depending on the treatment, the appropriate measurement value is selected. We would be happy to advise you which plant sensor is the most suitable for your farm.
The purchase of an ISARIA plant sensor includes initial use, first-year support and all future software updates for your plant sensor. Should further support be required in subsequent years, we offer cost-effective support packages. You can also use the ISARIA CONNECT data management application free of charge. There you can set up your business with all possible steps, upload, analyze and evaluate the sensor data. The application also gives you access to satellite maps as well as temperature and precipitation data from previous years. Based on this data, you can make well-founded crop management decisions and evaluate the success of plant protection measures. Additional costs only arise when the application cards, e.g. based on satellite maps, are downloaded.
The two plant sensors differ primarily in size and usability. The ISARIA PRO Active is an active sensor with its own light source and can therefore be used day and night. The ISARIA PRO Compact is a passive sensor and requires daylight for measurements. In addition, the ISARIA PRO Active is controlled via a separate terminal, and the ISARIA PRO Compact is controlled via the tractor's ISOBUS terminal.
Sensor data offers the advantage that you always have an up-to-date view of the state of the plant population, regardless of external influences such as cloudiness or peripheral influences (e.g. roadsides or forest edges on the edge of the field). Especially when fertilizing, it is essential to react to the current nitrogen uptake in the individual areas of the crop. This is the only way to influence the plant population in the right direction. Satellite maps have the disadvantage that up-to-date images are not always available — for example because no new images could be taken due to cloudiness. Here it may be that no usable recording is available for a period of three weeks or even more — and this is of course insufficient to deduce the current state of care.
In addition, when creating application maps from satellite data, the NDVI vegetation index (Normalized Difference Vegetation Index) is usually used, but this becomes saturated when plant stocks are well supplied (i.e. can no longer differentiate well-supplied plant populations). In late development phases, satellite maps no longer show any difference in plant population. Independent studies show that this is the case from a leaf area index of 1.5 — and a winter barley population already has a leaf area index of 1.5 at the beginning of the lap phase. This means that stocks can no longer be differentiated on satellite maps at the time when nitrogen fertilization actually really starts.
No separate GPS system is required to use the ISARIA plant sensors, as the sensors are already equipped with their own GPS system.
Site-specific management using plant sensors primarily helps you to allocate your resources as needed and to maximize your yields through optimal distribution. The risk of yield losses cannot be completely ruled out even by using plant sensors. But the optimal, demand-oriented application provides your plants with what they really need so that you can fully exploit the yield potential of your stock.
In principle, the ISARIA plant sensors are also worthwhile for farms with less than 100 ha of agricultural land. Whether a plant sensor is worthwhile for your farm depends on a wide variety of factors. What yield benefits can be achieved with the ISARIA plant sensor in practical use can be found in our white papers Read up.
Arrange a non-binding Consultation appointmentto check whether a plant sensor is worthwhile for your individual requirements.
Also interesting: The ISARIA plant sensor is on the BMEL positive list and is funded with up to 40% government subsidy. The individual federal states also offer their own funding programs. You can find more information about this here.
The ISARIA PRO Active has its own light source and can therefore be used day and night as it works independently of sunlight. Even taunlogging does not interfere with the measurement. Over the year, you can let the sensor run along with you every trip across the field. This means that you always have an up-to-date view of the status of your plants and can evaluate the collected data in ISARIA CONNECT and make decisions about your cultural management based on these findings.
The ISARIA PRO Active is usually mounted on the front hydraulics of the tractor. There are various mounting brackets for this purpose, which, for example, also allow the ISARIA PRO Active to be mounted directly on a front weight. It is controlled via a separate terminal. Both the sensor system and terminal only require a three-pin socket to supply power. There are various ways to communicate between the ISARIA terminal and the tractor or application device terminal. We offer various adapter solutions here. Feel free to talk to us about this.
The ISARIA PRO Active is mounted at the front of the tractor's front hydraulics. We offer various mounting brackets. This means that the ISARIA PRO Active can be easily assembled and disassembled by a single person. The ISARIA PRO Active is ready for use within a few minutes.
If your tractor does not have front hydraulics, we also offer alternative farming methods.
The ISARIA PRO Active is very lightweight compared to other sensors on the market. For tractors with front hydraulics, there is an attachment console with rollers, which can simply be rolled into the tractor. The rollers can be dismantled and stored on the back of the sensor while driving via a plug-in connection. This also makes dismantling easy and uncomplicated.
ISARIA also offers appropriate mounting brackets for vehicles without front hydraulics or with frontal weight.
Installation takes just a few minutes.
A WLAN module is installed in the ISARIA PRO Active terminal. This allows you to quickly and easily connect the terminal to an existing WLAN (e.g. home network or personal hotspot with the mobile device) and send or receive the data directly. Alternatively, the data can be transferred via a USB stick.
Application cards or orders created in ISARIA CONNECT can also be loaded onto the operator terminal via online data transfer or via USB stick.
The ISARIA PRO Active can be paired with all attachments known to us that support a variable output rate. Application devices controlled both serially and via ISOBUS can be connected.
When using the ISARIA PRO Active for the first time, a few settings must be made so that the application device can be controlled. When the sensor is delivered, you will be instructed by our employee. If you have any questions later or would like to pair a new attachment, you can find all information about this in the user manual for your sensor.
The ISARIA PRO Compact consists of two compact measurement sensors, which are mounted on the tractor's side mirrors, for example. There is also a reference sensor that is mounted on the roof of the tractor with a strong magnet and measures the incidence of sunlight. The sensor units are connected to each other via cable and to a small job computer, which is positioned in the tractor cabin. This job computer is then connected to ISOBUS.
The ISARIA PRO Compact is an ISOBUS device (AEF certified) and therefore does not require a separate control terminal. It is therefore operated via a standard ISOBUS terminal. If your tractor does not have an ISOBUS terminal, feel free to contact us. We can also offer you alternative solutions.
The ISARIA PRO Compact can be connected to all attachments that support a variable output rate. The output rate is transmitted via ISOBUS or via RS232.
The ISARIA PRO Compact sensor data is exported from the ISOBUS terminal together with all other data via a USB stick and can then be uploaded to the ISARIA CONNECT data management application. Application cards and order data, which are created in ISARIA CONNECT, can in turn be loaded onto a USB stick and then uploaded to the ISOBUS terminal.
The ISARIA PRO Compact can be easily assembled by yourself. The two sensor elements are mounted on the side-reflecting tractor; the reference sensor, which measures the incidence of light, is attached to the tractor roof with a magnetic plate. In the manual, you will find the height and angle angle requirements for the correct installation of the sensors. The components of the sensor can also be installed by a single person in just a few minutes.

The ISARIA PRO Compact is a passive sensor, meaning it does not have its own light source. The sensors record the sunlight reflected by plants in the red and near infrared ranges. A reference sensor on the tractor roof measures the prevailing lighting conditions and supplements the system. As long as there is sufficient daylight, the sensor can be used. If the prevailing lighting conditions are no longer optimal, you will receive a corresponding message from the system. So you don't have to check by yourself whether there is still enough light. During the fertilization season, for example, there is usually enough light from 7 a.m. to around 8 p.m., meaning that the sensor can be used around 13 hours a day. Of course, the working time varies depending on the season and the location.
An ISARIA CONNECT account can be connected to multiple sensors, but an ISARIA plant sensor can only be linked to one ISARIA CONNECT account. Your sensor data is therefore protected and cannot be viewed by anyone but you and the users you have created. In addition, the data is stored on secure servers in accordance with European or German data protection regulations and is not shared with third parties.

In ISARIA CONNECT, you can create application maps either based on your sensor data or on the basis of available satellite images. After entering a few parameters, the application map is calculated and saved. The application cards can be downloaded via an online shop and then transferred to the tractor.
This is due to various things, such as the measurement values used or the spatial resolution. When creating application maps from satellite data, the NDVI (Normalized Difference Vegetation Index) — this therefore measures the biomass growth of the plant population. At late stages of development, NDVI no longer recognizes differences in plant population and therefore does not show reliable data. Edge influences such as forest edges, fields, roadsides or defects can also lead to falsified results.
The ISARIA plant sensors, on the other hand, use reflected light in the red and near-infrared range to measure biomass growth and nitrogen saturation and thus provide reliable data both for moderate plant growth and for dense plant growth. Neighboring paths, meadows and trees are generally not included in the measurement from the tractor and therefore do not influence the measurement. Environmental influences such as deunlogging also do not influence the measurements.
