These calculated estimated emergence data can be used, for example, to adjust the application of a herbicide in the next planting season. For example, it can be determined when the weeds shown in the images have emerged.

This information can be used, for example, in the next planting season to apply a herbicide as close as possible to the time when a respective weed emerge, e.g. before the weeds sprout.
In an embodiment of the method for providing herbicide application data, the weed growth model may be configured to provide growth stage time data for at least one weed species, wherein the growth stage time data preferably refers to a growth stage of the weed species between BBCH 11 and BBCH 14, most preferably to a growth stage of the weed species of BBCH 12.

In an embodiment of the method for providing herbicide application data, the method may further comprise: providing historical weather data, actual weather data and/or predicted weather data; and wherein the weed growth model is further configured to provide weed emergence data and/or weed growth data for the agricultural field further based on the weather data.
Since the efficacy of some herbicides, e.g. soil herbicides, may dependent on a sufficient precipitation, in order to transport a soil herbicide to the roots of the plants, weather data may be used to decided to select a specific herbicide product, e.g. a specific soil herbicide dependent on the cumulative precipitation amount.
In an embodiment of the method for providing herbicide application data, the method may further comprise: providing historical weed distribution data for the agricultural field; and wherein the weed growth model is further configured to provide weed emergence data and/or weed growth data for the agricultural field further based on the historical weed distribution data. Because weeds may often occur in recurring local distributions, such weed distribution data, for example from previous seasons, may improve the application of a herbicide
In an embodiment of the method for providing herbicide application data, the method may further comprise: providing historical treatment data comprising information about treatments performed in previous seasons on the agricultural field, preferably comprising information about the mode of the historical treatment action; and wherein the weed growth model is further configured to provide weed emergence data and/or weed growth data for the agricultural field further based on the historical treatment data. By taking into account historical treatment data, for example, the risk of resistance formation due to the use of repetitive agents may be reduced.
In an embodiment of the method for providing herbicide application data, the method may further comprise: providing crop data comprising information about crops planted and/or planned to be planted on the agricultural field; and wherein providing herbicide application data is further based on the crop data. For example, by considering crop data, it is possible to evaluate whether a particular weed is at all harmful to a particular crop. In addition, the growth stage of the crop may also be taken into account. For example, it may be evaluated when a certain weed is no longer harmful for a certain growth stage of the corps, e.g. at a certain size of the crop, it may be determined that certain smaller weeds are essentially no longer harmful to the crop because the crop can suppress the weeds itself.
In an embodiment of the method for providing herbicide application data, the herbicide application data may spot application data for spot applying the herbicide product.

DETAILED DESCRIPTION OF EMBODIMENT
The following embodiments are mere examples for implementing the method, the system, the apparatus, or application device disclosed herein and shall not be considered limiting.
Figures 1 to 3 illustrate different computing environments, central, decentral and distributed. The methods, apparatuses, computer elements of this disclosure may be implemented in decentral or at least partially decentral computing environments. In particular, for data sharing or exchange in ecosystems of multiple players different challenges exist. Data sovereignty may be viewed as a core challenge. It can be defined as a natural person’s or corporate entity’s capability of being entirely self-determined with regard to its data. To enable this particular capability related aspects, including requirements for secure and trusted data exchange in business ecosystems, may be implemented across the chemical value chain. In particular, chemical industry requires tailored solutions to deliver chemical products in a more sustainable
way by using digital ecosystems. Providing, determining or processing of data may be realized by different computing nodes, which may be implemented in a centralized, a decentralized or a distributed computing environment.
Figure 1 illustrates an example embodiment of a centralized computing system 20 comprising a central computing node 21 (filled circle in the middle) and several peripheral computing nodes 21.1 to 21. n (denoted as filled circles in the periphery). The term “computing system” is defined herein broadly as including one or more computing nodes, a system of nodes or combinations thereof. The term “computing node” is defined herein broadly and may refer to any device or system that includes at least one physical and tangible processor, and/or a physical and tangible memory capable of having thereon computer-executable instructions that are executed by a processor. Computing nodes are now increasingly taking a wide variety of forms. Computing nodes may, for example, be handheld devices, production facilities, sensors, monitoring systems, control systems, appliances, laptop computers, desktop computers, mainframes, data centers, or even devices that have not conventionally been considered a computing node, such as wearables (e.g., glasses, watches or the like). The memory may take any form and depends on the nature and form of the computing node.
In this example, the peripheral computing nodes 21.1 to 21. n may be connected to one central computing system (or server). In another example, the peripheral computing nodes 21.1 to 21. n may be attached to the central computing node via e.g. a terminal server (not shown). The majority of functions may be carried out by, or obtained from the central computing node (also called remote centralized location). One peripheral computing node 21. n has been expanded to provide an overview of the components present in the peripheral computing node. The central computing node 21 may comprise the same components as described in relation to the peripheral computing node 21. n.
Each computing node 21, 21.1 to 21. n may include at least one hardware processor 22 and memory 24. The term “processor” may refer to an arbitrary logic circuitry configured to perform basic operations of a computer or system, and/or, generally, to a device which is configured for performing calculations or logic operations. In particular, the processor, or computer processor may be configured for processing basic instructions that drive the computer or system. It may be a semi-conductor based processor, a quantum processor, or any other type of processor configures for processing instructions. As an example, the processor may comprise at least one arithmetic logic unit ("ALU"), at least one floating-point unit ("FPU)", such as a math coprocessor or a numeric coprocessor, a plurality of registers, specifically registers configured for supplying
operands to the ALU and storing results of operations, and a memory, such as an L1 and L2 cache memory. In particular, the processor may be a multicore processor. Specifically, the processor may be or may comprise a Central Processing Unit ("CPU"). The processor may be a (“GPU”) graphics processing unit, (“TPU”) tensor processing unit, ("CISC") Complex Instruction Set Computing microprocessor, Reduced Instruction Set Computing ("RISC") microprocessor, Very Long Instruction Word ("VLIW') microprocessor, or a processor implementing other instruction sets or processors implementing a combination of instruction sets. The processing means may also be one or more special-purpose processing devices such as an Application- Specific Integrated Circuit ("ASIC"), a Field Programmable Gate Array ("FPGA"), a Complex Programmable Logic Device ("CPLD"), a Digital Signal Processor ("DSP"), a network processor, or the like. The methods, systems and devices described herein may be implemented as software in a DSP, in a micro-controller, or in any other side-processor or as hardware circuit within an ASIC, CPLD, or FPGA. It is to be understood that the term processor may also refer to one or more processing devices, such as a distributed system of processing devices located across multiple computer systems (e.g., cloud computing), and is not limited to a single device unless otherwise specified.
The memory 24 may refer to a physical system memory, which may be volatile, non-volatile, or a combination thereof. The memory may include non-volatile mass storage such as physical storage media. The memory may be a computer-readable storage media such as RAM, ROM, EEPROM, CD-ROM, or other optical disk storage, magnetic disk storage, or other magnetic storage devices, non-magnetic disk storage such as solid-state disk or any other physical and tangible storage medium which can be used to store desired program code means in the form of computer-executable instructions or data structures and which can be accessed by the computing system. Moreover, the memory may be a computer-readable media that carries computer- executable instructions (also called transmission media). Further, upon reaching various computing system components, program code means in the form of computerexecutable instructions or data structures can be transferred automatically from transmission media to storage media (or vice versa). For example, computer-executable instructions or data structures received over a network or data link can be buffered in RAM within a network interface module (e.g., a “NIC”), and then eventually transferred to computing system RAM and/or to less volatile storage media at a computing system. Thus, it should be understood that storage media can be included in computing components that also (or even primarily) utilize transmission media.
The computing nodes 21 , 21.1 to 21. n may include multiple structures 26 often referred to as an “executable component, executable instructions, computer-executable instructions or instructions”. For instance, memory 24 of the computing nodes 21, 21.1 to 21.n may be illustrated as including executable component 26. The term “executable component” or any equivalent thereof may be the name for a structure that is well understood to one of ordinary skill in the art in the field of computing as being a structure that can be software, hardware, or a combination thereof or which can be implemented in software, hardware, or a combination. For instance, when implemented in software, one of ordinary skill in the art would understand that the structure of an executable component includes software objects, routines, methods, and so forth, that is executed on the computing nodes 21 , 21.1 to 21. n, whether such an executable component exists in the heap of a computing node 21, 21.1 to 21. n, or whether the executable component exists on computer-readable storage media. In such a case, one of ordinary skill in the art will recognize that the structure of the executable component exists on a computer- readable medium such that, when interpreted by one or more processors of a computing node 21, 21.1 to 21. n (e.g., by a processor thread), the computing node 21 , 21.1 to 21n is caused to perform a function. Such a structure may be computer-readable directly by the processors (as is the case if the executable component were binary). Alternatively, the structure may be structured to be interpretable and/or compiled (whether in a single stage or in multiple stages) so as to generate such binary that is directly interpretable by the processors. Such an understanding of example structures of an executable component is well within the understanding of one of ordinary skill in the art of computing when using the term “executable component”. Examples of executable components implemented in hardware include hardcoded or hard-wired logic gates, that are implemented exclusively or near-exclusively in hardware, such as within a field- programmable gate array (FPGA), an application-specific integrated circuit (ASIC), or any other specialized circuit. In this description, the terms “component”, “agent”, “manager”, “service”, “engine”, “module”, “virtual machine” or the like are used synonymous with the term “executable component.
The processor 22 of each computing node 21 , 21.1 to 21. n may direct the operation of each computing node 21, 21.1 to 21. n in response to having executed computer-executable instructions that constitute an executable component. For example, such computer-executable instructions may be embodied on one or more computer-readable media that form a computer program product. The computer-executable instructions may be stored in the memory 24 of each computing node 21 , 21.1 to 21. n. Computer-executable instructions comprise, for example, instructions and data which, when executed at a processor 21, cause a general purpose computing node 21 , 21.1 to 21. n, special purpose computing node 21, 21.1 to 21. n, or
special purpose processing device to perform a certain function or group of functions. Alternatively or in addition, the computer-executable instructions may configure the computing node 21, 21.1 to 21. n to perform a certain function or group of functions. The computer executable instructions may be, for example, binaries or even instructions that undergo some translation (such as compilation) before direct execution by the processors, such as intermediate format instructions such as assembly language, or even source code.
Each computing node 21, 21.1 to 21. n may contain communication channels 28 that allow each computing node 21.1 to 21. n to communicate with the central computing node 21, for example, a network (depicted as solid line between peripheral computing nodes and the central computing node in Figure 1). A “network” may be defined as one or more data links that enable the transport of electronic data between computing nodes 21 , 21.1 to 21. n and/or modules and/or other electronic devices. When information is transferred or provided over a network or another communications connection (either hardwired, wireless, or a combination of hardwired or wireless) to a computing node 21 , 21.1 to 21. n, the computing node 21 , 21.1 to 21. n properly views the connection as a transmission medium. Transmission media can include a network and/or data links which can be used to carry desired program code means in the form of computer-executable instructions or data structures and which can be accessed by a general- purpose or special-purpose computing nodes 21, 21.1 to 21.n. Combinations of the above may also be included within the scope of computer-readable media.
The computing node(s) 21, 21.1 to 21. n may further comprise a user interface system 25 for use in interfacing with a user. The user interface system 25 may include output mechanisms 25A as well as input mechanisms 25B. The principles described herein are not limited to the precise output mechanisms 25A or input mechanisms 25B as such will depend on the nature of the device. However, output mechanisms 25A might include, for instance, displays, speakers, displays, tactile output, holograms and so forth. Examples of input mechanisms 25B might include, for instance, microphones, touchscreens, holograms, cameras, keyboards, mouse or other pointer input, sensors of any type, and so forth.
Figure 2 illustrates an example embodiment of a decentralized computing environment 30 with several computing nodes 21.1 to 21. n denoted as filled circles. In contrast to the centralized computing environment 20 illustrated in Figure 1, the computing nodes 21.1 to 21. n of the decentralized computing environment are not connected to a central computing node 21 and are thus not under control of a central computing node. Instead, resources, both hardware and software, may be allocated to each individual computing node 21.1 to 21. n (local or remote
computing system) and data may be distributed among various computing nodes 21.1 to 21. n to perform the tasks. Thus, in a decentral system environment, program modules may be located in both local and remote memory storage devices. One computing node 21 has been expanded to provide an overview of the components present in the computing node 21. In this example, the computing node 21 comprises the same components as described in relation to Figure 1.
Figure 3 illustrates an example embodiment of a distributed computing environment 40. In this description, “distributed computing” may refer to any computing that utilizes multiple computing resources. Such use may be realized through virtualization of physical computing resources. One example of distributed computing is cloud computing. “Cloud computing” may refer a model for enabling on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services). When distributed, cloud computing environments may be distributed internationally within an organization and/or across multiple organizations. In this example, the distributed cloud computing environment 40 may contain the following computing resources: mobile device(s) 42, applications 43, databases 44, data storage and server(s) 46. The cloud computing environment 40 may be deployed as public cloud 47, private cloud 48 or hybrid cloud 49. A private cloud 47 may be owned by an organization and only the members of the organization with proper access can use the private cloud 48, rendering the data in the private cloud at least confidential. In contrast, data stored in a public cloud 48 may be open to anyone over the internet. The hybrid cloud 49 may be a combination of both private and public clouds 47, 48 and may allow to keep some of the data confidential while other data may be publicly available.
Figure 4 illustrates a flow diagram of an example method for providing for providing herbicide application data for applying a herbicide product on an agricultural field.
In a first step, providing image data of an agricultural field are provided, e.g. by means of a camera unit mounted on a sprayer device. In a second step, a weed classification model configured to provide weed data based on the image data of the agricultural field is provided. In a further step, the weed classification model is applied to process the provided image data and to provide weed data as an output data. The weed data may comprise information about the weed plants, weed species, weed plant size, weed distribution, weed relevance for the crop, etc. In a further step, the provided weed data is used as input data for a provided weed growth model which is configured to provide weed emergence data and/or weed growth data for the agricultural field based on the weed data for the agricultural field. The weed emergence data and/or the weed growth data may subsequently be used to provide herbicide application data at
least comprising application timing data for at least one herbicide product, wherein the timing data may refer to the same season and/or to a subsequent season. In other words, the weed growth model may be applied for back-calculation to determine the time of weed emergence and/or the optimal timing of a herbicide application. This back-calculation data can then be used to determine a herbicide application time for the next season. However, the weed growth model may be applied for pre-calculation/prediction to determine a herbicide application in the same season, e.g. in a specific growth stage of the weed.
Figure 5 illustrates a schematic illustration of a system 10 for providing for providing herbicide application data for applying a herbicide product on an agricultural field. The system 10 for providing herbicide application data may comprise a first providing unit 11 configured to provide image data of an agricultural field, a second providing unit 12 configured to provide a weed classification model configured to provide weed data based on the image data of the agricultural field, a third providing unit 13 configured to provide weed data for the agricultural field based on the weed classification model and the image data; a fourth providing unit 14 configured to provide a weed growth model configured to provide weed emergence data and/or weed growth data for the agricultural field based on the weed data for the agricultural field; a fifth providing unit 15 configured to provide weed emergence data and/or weed growth data for the agricultural field based on the weed growth model and the weed data for the agricultural field; and a sixth providing 16 unit configured to provide herbicide application data based on the weed emergence data and/or weed growth data, wherein the herbicide application data at least comprising application timing data for at least one herbicide product for applying on the agricultural field.
Figure 6 illustrates exemplarily the different possibilities to receive and process field data.
For example, field data can be obtained by all kinds of agricultural equipment 300 (e.g. a tractor 300) as so-called as-applied maps by recording the application rate at the time of application. It is also possible that such agricultural equipment comprises sensors (e.g. optical sensors, cameras, infrared sensors, soil sensors, etc.) to provide, for example, a weed distribution map. It is also possible that during harvesting the yield (e.g. in the form of biomass) is recorded by a harvesting vehicle 310. Furthermore, corresponding maps/data can be provided by land-based and/or airborne drones 320 by taking images of the field or a part of it. Finally, it is also possible that a geo-referenced visual assessment 330 is performed and that this field data is also processed. Field data collected in this way can then be merged in a computing device 340, where the data can be transmitted and computed, for example, via any wireless link, cloud
applications 350 and/or working platforms 360, wherein the field data may also be processed in whole or in part in the cloud application 350 and/or in the working platform 360 (e.g., by cloud computing).
