DETAILED DESCRIPTION OF EMBODIMENTS
[0043]
[0044] According to embodiments, the device comprises a GPS unit 70. The processing unit is configured to determine at least one geographical location of the field. The determination of the at least one geographical location comprises utilization of the GPS unit. The information transmitted by the transmitter can then comprise the at least one geographical location of the field.
[0045] In some embodiments, the device is configured to receive satellite imagery of the landscape. In this way, a GPS determined location can also be correlated to satellite imagery in order to determine the extent and boundaries of the farmer's field from field boundaries observed in the satellite imagery. In some embodiments, the processing unit is configured to use imagery processing, such as edge detection filters to determine the field boundaries.
[0046] In some embodiments, from a general GPS determined location, satellite imagery can be interrogated to provide the farmer with a number of bounded fields, any one or more of which could be their field or fields. These for example could be colour coded. These images of fields are then presented to the farmer, for example on the screen of a smart phone. The farmer, looking at these fields located as they are within satellite imagery, will immediately, from geographical contextual information, such as his field has a big tree in the corner or is next to a stream or is next to the triangular field, for example, be able to indicate which of these fields is his field. This can be done by touching the screen at the position of his or her field, where for example a smart phone has a touch sensitive screen. The potential fields can be presented in different colours to the farmer, making it easier to see the different fields in terms of structure and in the context of the surrounding geographical information.
[0047] Advice to the farmer can relate to information such as, what crop to grow, how to grow a crop, what herbicide, insecticide or fertilizer to use, when and for what reason, whether there is no need to use a herbicide, insecticide or fertilizer and why they are not needed, when to water the crop, when to sow to the crop and when to harvest the drop. The information provided to the farmer can relate to what disease is affecting the crop, what pest is affecting the crop and how to remedy the situation through for example application of a herbicide or insecticide and when and how it should be applied. The advice can relate to when to harvest the crop, how much of the harvest in a field to harvest at any time, where and when to sell the crop and what price is to be expected. The cost implications of all of these actions, with respect to profit and loss, when the farmer finally comes to sell the product can be presented to the farmer.
[0048] According to some embodiments, determination of the at least one geographical location of the field comprises at least one movement of the GPS unit.
[0049] According to some embodiments, the at least one movement comprises the device being moved around at least one boundary of the field.
[0050] According to some embodiments, the at least one movement comprises the device being moved around all of the boundaries of the field.
[0051] According to some embodiments, the device comprises a camera 80. The camera 80 is configured to enable the user to acquire at least one image relating to the at least one crop. The information transmitted by the transmitter can then comprise the at least one image relating to the at least one crop.
[0052] In some embodiments, the at least one image relating to the at least one crop comprises an image of the ground or soil within which the at least one crop is growing and or is to be grown.
[0053] In some embodiments, the at least one image relating to the at least one crop comprises at least one part of the field. Determination of the at least one geographical location of the field in these examples can then comprise utilization of the at least one image.
[0054] In some embodiments, the device is configured to receive satellite imagery of the landscape, and the processing unit is configured use the satellite imagery and the at least one image acquired by the camera of the device in determining the at least one geographical location. In other words, features that are in the acquired image can be compared and/or mapped onto satellite imagery in order to augment the GPS information to determine the at least one geographical location.
[0055] In some embodiments, the at least one image comprises at least one image of at least one boundary of the field.
[0056] In some embodiments, the at least one image comprises images of all of the boundaries of the field.
[0057] Thus, the exact size and location of the boundaries of a field can be determined on the basis of GPS derived information and image derived information. In this way, positional errors in GPS data can be mitigated through utilization of a whole series of images of a boundary of a field. These images can be compared with satellite imagery in order to determine the location of the field. Or, as the farmer walks around a field a whole series of images of the field boundary can be acquired. These can be rendered together to form a seemless synthetic boundary of the field, enabling the exact location of the field boundary and this the exact size of the field to be determined. As part of this image based process, the device such as a smart phone can utilize motion sensors, such as inertial navigation sensors, to determine the distance moved between the acquisition of each image. This information can be used to provide a real size to the dimensions of the synthetic boundary rendered from the images of the field boundary, enabling the exact geographical location of the boundary to be determined. This can augment the GPS derived location information.
[0058] According to some embodiments, the at least one image relating to the at least one crop comprises an image of the at least one crop. In some embodiments, the at least one image relating to the at least one crop comprises an image of a weed, and/or pest and/or disease of the at least one crop. According to some embodiments, the economic information relating to the at least one crop comprises pricing information relating to the at least one crop.
[0059] In some embodiments, the pricing information relates to historical pricing information. In some embodiments, the pricing information relates to predicted pricing information. In some embodiments, the pricing information is predicted making use of historical pricing information. In some embodiments, the pricing information is predicted making use of weather forecast information. In some embodiments, the pricing information is predicted making use of at least one image relating to the crop. In an example, the image relates to the plants that are growing thus an assessment can be made as to the health of the crop and the expected price that the crop could get when harvested. In some embodiments, the image relates to the fruits that are growing thus an assessment can be made as to the expected price that could be achieved when harvested. In some embodiments, the at least one image relating to the crop comprises satellite imagery of the area surrounding the field. In this way, image analysis can determine what type of crops are being grown in the locality. Thus, if the farmer is growing the same crop as other farmers then the price she may achieve may not be as good as the price she could get if the surrounding farms are growing different crops. Satellite imagery over a number of years can be interrogated to determine what crops were grown over previous years and this can be correlated with the price of different crops in the local markets over those same years, and this information can be used with satellite imagery of the fields in the area this year in order to better determine the expected price for the farmer's crop in the local markets when she comes to sell the crop, and can better determine which markets top sell the product. This information can also be used to advise the farmer what crop to grow, in that it could be a good decision to grow a crop that other farmers are not or appear not to be growing, because there could be a price premium for such a scarce resource when she comes to sell the crop in a local market.
[0060] In some embodiments, the economic information relating to the at least one crop comprises information relating to markets in the locality of the field.
[0061] In some embodiments, the economic information relating to the at least one crop comprises information relating to the crops sold at markets in the locality of the field.
[0062] In some embodiments, the pricing information relates to historical pricing information at markets in the locality of the field.
[0063] In some embodiments, the economic information relating to the at least one crop comprises historical information relating to the quantities of crops sold at markets in the locality of the field.
[0064] According to some embodiments, the input unit is configured to enable the user of the device to input an information request relating to the at least one crop. Determination of the economic agricultural management information can then comprise utilization of the information request relating to the at least one crop.
[0065] According to some embodiments, the economic agricultural management information comprises one or more of: what crop to sow; when to sow the crop; when to harvest the crop; when to sell the crop; where to sell the crop; what price is expected for the crop; whether to harvest and sell in stages and where to then sell the harvested crops; what to do to improve the quality and/or yield of the crop and what effect this has on the expected financial return for the crop; and whether to use a fertilizer, a herbicide and/or an insecticide and what effect this has on the expected financial return for the crop.
[0066]

in an outputting step 150, also referred to as step f), outputting, using an output unit of the device, the economic agricultural management information to the user of the device.
According to some embodiments, the device comprises a GPS unit, and wherein step a) comprises determining at least one geographical location of the field, the determination comprising utilization of the GPS unit. The information transmitted by the transmitter can then comprise the at least one geographical location of the field.
[0067] In some embodiments, determination of the at least one geographical location of the field comprises at least one movement of the GPS unit.
[0068] In some embodiments, the at least one movement comprises the device being moved around at least one boundary of the field.
[0069] In some embodiments, the at least one movement comprises the device being moved around all of the boundaries of the field.
[0070] According to some embodiments, the device comprises a camera, wherein step a) comprises the user acquiring at least one image relating to the at least one crop using the camera. In step c) the information transmitted by the transmitter can comprise the at least one image relating to the at least one crop.
[0071] In some embodiments, the at least one image relating to the at least one crop comprises an image of the at least one crop.
[0072] In some embodiments, the economic information relating to the at least one crop comprises pricing information relating to the at least one crop.
[0073] According to some embodiments, the method comprises step b) inputting 160 by the user, via an input unit of the device, an information request relating to the at least one crop. Step e) can then comprise utilization of the information request relating to the at least one crop.
[0074] In some embodiments, the economic agricultural management information comprises one or more of: what crop to sow; when to sow the crop; when to harvest the crop; when to sell the crop; where to sell the crop; what price is expected for the crop; whether to harvest and sell in stages and where to then sell the harvested crops; what to do to improve the quality and/or yield of the crop and what effect this has on the expected financial return for the crop; and whether to use a fertilizer, a herbicide and/or an insecticide and what effect this has on the expected financial return for the crop.
[0075]
[0076] At this point, the mobile phone accesses a remote server via normal telecommunication transmissions, and information is downloaded to the smart phone. This information indicates what crops would be best to grow in that field, where to sell such crops, what prices could be obtained for such crops, and information enabling the cost/benefit of using fertilizers, herbicides, pesticides to be determined. Knowing the size of the field, the farmer is provided with information regarding how much seed for example is required, with this information being presented for example on the screen of a mobile phone such as a smart phone. The farmer is also provided with information relating to what the expected yield for her crop will be, and whether local markets at the expected time of harvest will be able to accommodate her harvest. The farmer is also provided with information relating to which markets it would be best to use, and what price she might be expected to get. If the farmer has uploaded information relating to the crop, such as information on the soil type, images of the plants growing, and images of the fruits/crop themselves/itself, as well as images that shows information relating to pests and diseases this information can be used to provide the farmer with more accurate expected pricing information, and information relating to how to mitigate such problems and the associated cost and how it could impact the price she could achieve. Thus, the farmer can be provided with information relating to the costs of using fertilizer, herbicide and pesticide and what effect these would have on an anticipated sale price. Also, if there is no need to use fertilizer, herbicide/pesticide the farmer can be provided with this information.
[0077] Thus the remote server, from the general location of the user, and the other information as detailed, can provide information regarding the type of crop that could be grown and the seed sowing rate per unit area, as well as economic data relating to selling the product and how best to prepare the product for sale. A processor in the smartphone can then process this downloaded information, to provide the farmer with information regarding the actual amount of seed required for her field, and where to sell the final product and when.
[0078] In addition to being advised what crop to grow, the farmer can indicate the specific crop that she is growing, and can provide information via a keyboard (keypad of the mobile phone) and or take images regarding other information such as images of weeds, diseases and pests, and images of the crop/fruit itself and be provided with economic information relating to the crop, for example where and when and for what price to sell the crop. The information indicated by the farmer is again transmitted to the remote server, and the information provided back to the farmer indicates information such as what herbicides or pesticides/insecticides to use and how and when to use them as well as the quantities required, as well as the cost benefits relating to such use in terms of the effect of price that is to expected. The farmer is also provided with information relating to what markets to use, what the expected sale price could be, based on historical information, and the expected quality and yield of her crop when she will harvestagain she can be advised when to harvest, that could be at a non-optimum time with respect to the quality of her crop, but which is at a time when a better price is expected to result. The information also specifies when to water the crop and when to harvest it, in addition to how to prepare the crop for sale and where and when to sell, and what price could be expected.
[0079] Rather than use a remote server, if the smartphone has sufficient memory the database of information is held on the remote server and the processing that is done to locate the field, and determine weeds/pests, and determine the economic information etc resides on the smartphone itself. In this case, information need not be sent to the remote server, but the farmer can be provided with the economic agricultural management information even in remote locations with no telephonic coverage.
[0080]
[0081] Information downloaded to the phone also relates to the location of local markets, what they sell, and pricing information at those markets for different products as well as the quantities of products that can be sold in particular markets. This information can be considered to form part of agricultural data, and the processor of the smart phone utilizes this dataset to drill down and provide specific tailored information to the farmer. In
[0082] With continued reference to
[0083]
[0084] Continuing with
[0085] The farmer also requests information relating to how she should manage the tomato crop in her field, with
[0086]
[0087]
[0088] In
[0089] Different factors relating to the provision of the cropping calendar are now discussed:
CONTENT LIBRARY
Crop
[0090] This relates to agronomic growth stages, time and timing for each crop. The crop dynamics influence the farming practices. E.g.: Farming practices followed in a paddy are different to those required in growing Tomatoes.
Products
[0091] Product catalog consists of products details, such as products from Bayer. And provides detail such as: features, benefits, mode of action, recommended crop, target pests, method of application, pre harvest interval etc.
Pests
[0092] The pests module consist of pest name, symptoms caused by pests, control measures recommended control measures.
Best Practices
[0093] The farming practices recommended for profitable farming. These practices include standard practices and custom practices. Standard practices: The farming practices generally followed by farmer in a specific crop stage. E.g. basal fertilizer application during sowing stage. Spacing to be followed during later stages. Custom practices: The farming practices followed by the farmer as a special case to improve the farm productivity.
[0094] Influencing Factors refer to the external factors that define the set-up of crop stages, time and timing.
INFLUENCING FACTOR
Season
[0095] Agriculture year is divided into several seasons (spring, summer, autumn, and winter) marked by particular weather patterns which influence the growth cycle of crop and incidence of pests.
Crop
[0096] Crop is the plants cultivated for commercial purpose in the field. In case of mixed cropping, more than one kind of crop might be grown in the same field. Primary crop/main crop shall be considered for creating cropping calendar. A field can have only one main crop for which the cropping calendar will be generated.
Variety
[0097] Self-pollinated varieties or hybrids of a crop grown by the farmer. Eg: Abhinav, Laxmi in Tomato.
Farm
[0098] Unit of land where the crops are grown. This will be a permanent location, area or the coordinates are not changed often. A farmer can have multiple farms.
Field
[0099] Sub unit of Farm, which may change (area) every season as the farmer grows different crops. A farm can have multiple fields.
[0100] Core components are integral components of cropping calendar that controls the life cycle of cropping calendar (start to end).
CORE COMPONENTS
Controller
[0101] Controller is, for example, a kind of rule engine developed specifically for the purpose of the cropping calendar. Controller analyzes the data received from external services and interacts with other core components.
Scheduler
[0102] Spring scheduler initiates the process to gather information from external services, run the rule engine and identify the events that should be sent to the mobile application.
Notification Service
[0103] Notifications service allows server to send different types of alerts and notifications to the mobile app. To generate notifications, Cropping Calendar service interacts with external services.
Sync Service
[0104] Sync Service enables users to synchronize the data from the server. It will be invoked in periodic fashion (at a scheduled time) or on a state change (dynamic/real time). Last successful sync timestamp will be used for syncing subsequent state changes between server and app.
[0105] If the response is too big to handle in a single response then it will be split into multiple logical parts and will be transferred. Client receives all the splits and updates it in local data repository. If the data is not completely received due to any reason then it will be completely rolled back at client side and a fresh request for update will be initiated during next execution of Sync invocation.
Crop Stage Model
[0106] The timelines of a crop calendar is generated based on the Crop stage, timing and time. Standard crop stages defined by agronomists will be mapped with the local crop stages that will be shown in mobile app. Timelines of crop calendar start from specific date (e.g. sowing date1 Sep. 2017) and end after harvesting. The interval between crop stages is timing (e.g. Germination takes 10 days after sowing) and the dates derived based on timing will be shown as time (Germination commence on 10 Sep. 2017).
Events
[0107] An event is a triggered cropping calendar information which will be displayed along crop stages. Events are classified into 4 categories based on the severity.
1. InformationNo remedial action is required. for example, notify famer on a new growth stage attained by the crop.
2. Alert/WarningInvestigate to decide if an action is required. For example, Alert sent when the weather conditions congenial for pests and diseases
3. Input adviceAction is required by the farmer. For example, Spray Nativo to control late blight of Tomato.
4. Fatal eventA disaster is likely to occur. For example, cyclone/hurricane is predicted to destroy the crop
Feedback
[0108] Feedback is a component that allows farmers to provide information related to the events/farming practices. Standard feedback is the data capture in a predefined template. Custom feedback is a general data capture template designed to allow farmers provide specific feedback which is not covered in standard templates. Example of data types required for specific farming related data capture is given below. [0109] Date: Date of sowing, date of application, date of harvest, etc. [0110] Text/comments: A text entry field required in all the feedback templates to capture verbal and qualitative inputs from farmer [0111] Number entry: A field to capture the data like cost of plant protection application, dosage applied by farmer etc. [0112] Picture: Attach a picture along with the feedback entered. E.g. capture the picture of a product used for plant protection, capture the picture of pests and diseases in farm. [0113] Radio button: Allow farmer to select Yes/No answers. E.g. was the recommendation useful [0114] Yes/No. [0115] Drop down or Combo-box: Allow farmers to select from the pick list instead of data entry. Eg. List of Bayer products in a drop down menu. [0116] Check box: For example, allow farmers to select the check box if a recommended practice is followed.
[0117] Mobile platform plays a vital role in enabling most of the features built in the mobile application. Mobile device with better OS capabilities provide optimal user experience.
MOBILE PLATFORM
Mobile Controller
[0118] Mobile controller rule engine is similar to the controller in server which is designed specifically to analyze the data gathered from external services and interact with other core components.
Mobile Operating System
[0119] Operating system (OS) interact with the mobile controller and allows the application to utilize the hardware and software resources. E.g. the capabilities for local language, keyboard, screen size, camera resolution, performance, processing speed, offline usage etc.
[0120] Digital farming services and other third party services provide information related to external factors that trigger core components to generate events in cropping calendar.
EXTERNAL SERVICES
Weather
[0121] Weather API from digital farming services provide weather daily and hourly weather forecast on regular intervals. The information is useful for farmers to plan and manage farm activities.
Alertas/Risk Service
[0122] The Alertas provide weather and location based alerts and information related to pests and disease incidence, which in turn filtered by controller and relevant crop stage specific alerts are provided in cropping calendar.
Scouting
[0123] Service provided by digital farming platform enables farmers to send pictures of weeds, pests and diseases and identify pests and obtain control measures.
Market Price
[0124] Market price information from third party services will be funneled through controller for personalized alerts to farmer's interest.
Partner Service
[0125] Services from other partners/stakeholders, for example of Bayer, to provide information like recommendation on application of fertilizer for better results based on soil nutrient conditions.
